Mercedes-AMG presents the high-end super sports car version of the gull-wing model, the new SLS AMG Coupé Black Series. Inspired by the SLS AMG GT3 racing version, the fifth Black Series model from Mercedes-AMG boasts a fascinating mix of breath-taking design, outstanding driving dynamics and uncompromising lightweight construction in accordance with the “AMG Lightweight Performance” strategy. With a DIN kerb weight of 1550 kilograms, the SLS AMG Black Series achieves a power/weight ratio of 2.45 kg/hp. The AMG 6.3-litre V8 engine generates a power output of 464 kW (631 hp) at 7400 rpm and accelerates the most dynamic gull-wing model of all time to 100 km/h in 3.6 seconds. The coil-over AMG RIDE CONTROL performance suspension, the AMG ceramic high-performance composite brake system and the weight-optimised forged AMG light-alloy wheels with newly developed sports tyres combine with the electronically controlled AMG rear-axle differential lock and the AMG SPEEDSHIFT DCT 7-speed sports transmission featuring uncompromisingly emotional shift and response times to raise the SLS AMG Black Series to a new level. The AMG Aerodynamics package is optionally available to further boost the vehicle’s driving dynamics.
Black Series – a name that resonates with automobile experts and enthusiasts. Following on from the SLK 55 AMG Black Series from 2006, the CLK 63 AMG Black Series (2007), the SL 65 AMG Black Series (2008) and the C 63 AMG Coupé Black Series (2011), the fifth exponent sees the Black Series entering a new dimension with the gull-wing model.
“The new SLS AMG Coupé Black Series is a perfect study in the one hundred percent transfer of technology and engineering from motorsport to the road. We have drawn inspiration from the worldwide success of the SLS AMG GT3 customer sport racing car on both a conceptual and a technological level. Boasting numerous lightweight components and fascinating driving dynamics, our fifth Black Series model guarantees pure, unadulterated ‘Driving Performance’. The SLS AMG Coupé Black Series is the ultimate choice for fast laps and highly emotional driving experiences”, says Ola Källenius, Chairman of Mercedes-AMG GmbH.
“The most dynamic gull-wing model of all time goes by the name of the SLS AMG Coupé Black Series. Fans of high-performance super sports cars will be fascinated by its high-tech package. The basis for passionate performance and supreme driving dynamics is provided by numerous new developments in the area of the engine, power transmission, suspension and aerodynamics – also according top priority to our “AMG Lightweight Performance” strategy. Great efforts in the field of lightweight design have resulted in a DIN kerb weight of 1550 kilograms,” notes Tobias Moers, head of overall vehicle development and member of the management board of Mercedes-AMG GmbH.
AMG 6.3-litre V8 engine a byword for thrilling driving dynamics
The uprated AMG 6.3-litre V8 engine generating a power output of 464 kW (631 hp) and 635 Newton metres of torque is a byword for thrilling driving dynamics, making the SLS AMG Coupé Black Series the most powerful AMG high-performance automobile with a combustion engine at present. Only the SLS AMG Coupé Electric Drive with a maximum output of 552 kW comes with greater power reserves.
The SLS AMG Coupé Black Series accelerates to 100 km/h in 3.6 seconds. The top speed stands at 315 km/h. The additional 44 kW (60 hp) of power in comparison to the 420 kW (571 hp) offered by the SLS AMG has been achieved by the following measures:
• Increase in maximum engine speed from 7200 to 8000 rpm
• Fully revised high-speed valve train with modified camshafts, adapted cam geometry and optimised bucket tappets featuring a special coating which is otherwise exclusive to racing vehicles
• Modification of the intake air ducting: derestriction and adaptation to the new maximum engine speed
• Adaptation of the engine application and increase in peak pressure
The engineers at Mercedes-AMG have further optimised the crank assembly in the interests of optimum stability in tough racing use. The measures carried out here include modified oil bores in the crankshaft, new crankshaft bearings, a new oil pump and high-strength screwed connections for the conrods. The entire water and oil cooling system for the engine and transmission has also undergone further optimisation. The AMG V8 engine in the SLS AMG Coupé Black Series is additionally provided with a special support system. A gas-filled strut braces the eight-cylinder engine on the body, effectively eliminating undesired load change reactions in highly dynamic driving on the race track. The AMG 6.3-litre V8 engine is hand-built at the AMG hand-finishing section in Affalterbach, according to the philosophy “one man, one engine”. This hand-made quality is confirmed by the black AMG engine badge bearing the responsible engine fitter’s signature which is a hallmark of the Black Series models.
The eight-cylinder naturally aspirated engine installed as a front mid-engine behind the front axle boasts racing car-style response and livelier than ever revving ability. The powerful AMG V8 engine’s race track aspirations are also apparent in its sound: the newly designed AMG sports exhaust system, produced in titanium for the first time, features distinctive centre and rear mufflers which provide for a more powerful and even more striking engine sound. The switch from steel to titanium has spawned substantial weight savings: at just under 17 kilograms, the new AMG sports exhaust system is around 13 kilograms lighter than its predecessor. The new system features the performance-enhancing fan-type exhaust pipes which have been in use to date.
Systematic application of the AMG Lightweight Performance strategy
Lightweight at its core: with a kerb weight of 1550 kilograms (DIN), the new SLS AMG Coupé Black Series is not only 70 kilograms lighter than the SLS AMG, but also attains the best power/weight ratio of all AMG Black Series vehicles to date by far. The figure of 2.45 kg/hp will also bear up to comparison in the super sports car scene. Such a ratio is made possible by systematic application of the “AMG Lightweight Performance” strategy. Numerous body elements, such as the bonnet, the rear panel behind the AMG sports bucket seats, the diagonal braces on the underbody and the torque tube between engine and transmission consist entirely of the motorsport material carbon fibre (carbon fibre-reinforced plastic). In contrast to its 26.6-kilogram counterpart with sand-cast aluminium housing, the carbon-fibre torque tube weighs only 13.3 kilograms. As previously, power transmission between the engine and the dual clutch transmission (transaxle principle) which is flange-mounted on the rear axle is effected by means of a carbon fibre-reinforced plastic (CRP) drive shaft weighing only 4.7 kilograms. A number of parts on the aluminium spaceframe have also been replaced by CRP components. A lithium-ion battery which is used in place of the conventional starter battery saves a further eight kilograms.
Dual clutch transmission for even more emotional dynamism
The overall power transmission system is also a major contributory factor to the outstanding driving dynamics of the SLS AMG Coupé Black Series. The AMG SPEEDSHIFT DCT 7-speed sports transmission is installed ten millimetres lower in order to achieve a lower centre of gravity for the vehicle and is braced against the body by gas-filled struts in order to avoid stress cycles. The dual clutch transmission features four driving modes (C, S, S+ and M). “Sport plus” and “Manual” in particular provide for markedly sportier performance than with the SLS AMG and SLS AMG GT models. In addition to an increase in shifting speed, the reduced response time to shift commands from the driver and the shifting hardness provide for pure dynamism.
An even more thrilling feature is the automatic double-declutching function during downshifting: the throttle blips when shifting gear are more pronounced and more strikingly audible than ever, due to the AMG titanium sports exhaust system. There is also a new temporary M mode. In C, S or S+ mode, this enables the driver to activate manual mode without having to remove a hand from the steering wheel, by pressing the “up” or “down” shift paddle once. In temporary M mode the driver experiences the dynamism and performance of gear-shifting in manual mode in all of the automatic driving programmes, with automatic up- and down-shifting into the bargain. This allows the driver to devote his full attention to the vehicle’s impressive performance.
New, electronic AMG rear-axle differential lock
A newly developed, electronically controlled AMG rear-axle differential lock with a shorter rear-axle ratio replaces the mechanical variant; it is integrated in the compact transmission housing. This system operates with a variable locking effect in acceleration and deceleration mode; in addition, the electronics respond more sensitively than to date, enabling excellent traction for the driven wheels at all friction levels. The electronic AMG rear-axle differential lock also benefits driving safety: in slaloms or when changing lane at high speeds the system has a stabilising effect, as it is able to attenuate the vehicle’s yaw rate around its vertical axis. The standard-fit 3-stage ESP® system featuring the functions “ESP ON”, “ESP SPORT Handling Mode” and “ESP OFF” is precision-tuned to the electronic AMG rear-axle differential lock. The same applies to the RACE START function, which provides for perfect traction when accelerating from a standing start in conjunction with the electronic differential lock.
AMG RIDE CONTROL performance suspension and sports tyres
The chassis and suspension of the SLS AMG Coupé Black Series are also new. The basic layout with double wishbones all-round in aluminium remains unchanged, but barely a component has gone untouched in the interests of much enhanced race track performance.
The new developments in detail:
• AMG RIDE CONTROL performance suspension with tauter basic tuning and electronically controlled two-stage damping (Sport, Sport +) for individual adjustment to the preferred personal driving style
• Coil-over spring retainers to enable adjustment of wheel loads for personal race track set-ups
• Elastokinematics 50 / 42% more rigid (front/rear axle) for greater stability in fast double bends
• Track width increased by 20 / 24 millimetres (front/rear axle) for added grip in fast bends
• New wheel carriers on front axle and new front stabiliser tuning for added grip, reduced roll angle in fast cornering
• AMG 10-spoke light-alloy wheels, in particularly light forged design with optimised strength, painted matt black with high-sheen finish, dimensions: 10×19 at fron; 12×20 at rear. Weight saving: 4.0 kilograms
• Newly developed Michelin Pilot Sport Cup 2 sports tyres. Dimensions 275/35 R 19 at front and 325/30 R 20 at rear, for added grip and sporty cornering limit
AMG speed-sensitive steering with newly defined power steering characteristic for optimum steering precision and outstanding control of the vehicle
AMG ceramic high-performance composite brake system as standard
The brake system of the SLS AMG Coupé Black Series boasts excellent deceleration performance and outstanding stability. The AMG ceramic high-performance composite brake system comes as standard. The ceramic brake discs measuring 402 x 39 millimetres at the front and 360 x 32 millimetres at the rear feature increased hardness for enhanced thermal stability, accompanied by a weight reduction of around 40 percent. As a result of the reduced unsprung masses, they optimise both comfort and grip. The reduced rotating masses on the front axle provide for more direct steering response. Weight savings with the AMG ceramic high-performance composite brake system compared to a conventional steel/aluminium brake system: 16 kilograms.
Design inspired by the SLS AMG GT3 customer sport racing car
The design of the SLS AMG Coupé Black Series derives a special fascination from its similarity to the SLS AMG GT3 customer sport racing car. The gull-wing racing car developed in accordance with FIA GT3 rules has quickly become established as a serious contender among the super sports car elite. In the 2012 motorsport season the SLS AMG GT3 is competing in more than 15 series on four continents. The triple victory in the 24-hour Dubai race in January 2012, three driver and team titles in the FIA GT3 European Championship, the ADAC GT Masters and the FIA GT3 World Championship along with numerous places on the podium at various short-distance, 4- and 6‑hour races demonstrate the SLS AMG GT3′s sporty performance in impressive style. To date, the car has notched up 37 victories in the 2012 season (as per 28 October 2012).
Wide flared wings with an added width of 13 mm (front) and 26 mm (rear) on each side create the necessary space for the 275 mm and 325 mm sports tyres. Darkened headlamps and black surrounds for the rear lights provide the SLS AMG Coupé Black Series with a muscular and aggressive look. The vehicle’s aerodynamic balance is optimised by the front apron and rear apron with diffusor along with side sill panels in Black Series-specific design featuring carbon fibre-reinforced plastic front splitter, carbon inserts in the side sills and the rear apron made of carbon fibre. The enlarged air intakes with carbon-fibre flics additionally ensure an optimum air inflow into the cooling modules at the front.
As on the SLS AMG GT3, the carbon-fibre bonnet features a central air outlet. Apart from effectively discharging the engine heat, this outlet also increases downforce at the front axle and improves the Cd value. The wing-like cross-fin and the star recess in the radiator grille are finished in high-gloss black to match the exterior mirrors and the fins on the bonnet. The carbon-fibre insert on the sides with air outlet and a black fin is also reminiscent of the GT3; this feature also helps to reduce the temperature level in the engine compartment. The upshot is maximum stability, even in tough race track use.
Matt black AMG forged wheels in Black Series-specific design
A striking feature on the sides is the attractive integration of the side skirts, which combine with the side feature line in appealing fashion. The carbon elements fitted along the bottom at the sides continue the line of the carbon-fibre front splitter along to the rear. AMG forged wheels in a series-specific 10‑spoke design, painted in matt black with a high sheen finish, provide glimpses of the AMG ceramic high-performance composite brake system. AMG forged wheels in matt black with high-sheen rim flange are alternatively available.
The rear of the SLS AMG Coupé Black Series presents a brawny appearance on a par with that of the front end. The wide wings and the striking rear diffusor are the predominant features here. The diffusor extends beyond the profile of the rear apron and produces additional downforce at the rear axle. This results in greater driving stability at high speeds. Visible air openings behind black grilles serve to control the dischrage of hot air in the area of the AMG titanium sports exhaust system. The two sets of twin chrome tailpipes with a square cross-section provide a visual demonstration of the gull-wing super sports car’s power and dynamism – an impression that is backed up by a corresponding sound. The exclusive AMG logo with contrasting Black Series lettering in black adds a discreet yet striking touch at the top right of the boot lid.
AMG Aerodynamics package with carbon-fibre components
The SLS AMG Coupé Black Series can be upgraded with the optional AMG Aerodynamics package. This package features a fixed, adjustable carbon-fibre rear aerofoil in the style of the SLS AMG GT3 in place of the standard-fit aerofoil which extends automatically at speeds of over 120 km/h. The rear aerofoil is braced by aluminium elements on a special insert on the boot lid and provides for even greater negative lift force on the rear axle – not least of all as a result of the Gurney flap, named after its inventor, Dan Gurney, a former racing driver, designer and team owner. This eight millimetre-high spoiler lip fitted to the rear aerofoil at an angle of 90 degrees results in a further increase in downforce without significantly increasing drag. The rear aerofoil is complemented by additional carbon-fibre flics on the front apron which further reduce downforce at the front axle, as opposed to the more inward-lying standard-fit carbon-fibre flics which serve to optimise the inflow of air into
the cooling modules.
The optionally available expressive colour AMG solar beam is exclusive to the SLS AMG Coupé Black Series. Six other exterior paint finishes from the SLS AMG range are available, including the matt paint designo magno alanite grey.
Sporty, functional interior exuding high quality
A functional, sporty racing-car atmosphere is prevalent inside the SLS AMG Coupé Black Series, with high-quality materials demonstrating precision workmanship and exquisitely designed details. There is a choice of two colour variants: Alcantara® black or Alcantara® black/red. With the two-tone variant, the door centre panels and the applications on the centre console and above the glove compartment are finished in red. The AMG Performance steering wheel with flattened bottom rim section features Alcantara® all round for a good grip. In the top section the steering wheel features a sporty red 12 o’clock marking. The real metal bezel features a high-gloss black paint finish to match the high-gloss black surrounds of the air vents. A particularly high-quality and exclusive Black Series detail is the so-called “3D seam” which runs horizontally along the dashboard: a fine Alcantara® strip in anthracite features across the entire width of the leather covering. Red contrasting stitching in the leather lend an accomplished finish to the 3D seam, underscoring the hand-crafted character.
The combination of designo leather and Alcantara® features throughout the interior – on the bottom section of the dashboard, for example, on the door centre panels and on the AMG sports bucket seats, whose centre sections are covered with Alcantara®. Embossed AMG emblems on the head restraints are further exclusive eye-catchers. In addition to providing first-class lateral support at high cornering speeds, the AMG sports bucket seats are also 15 kilograms lighter than the standard AMG sports seats.
The absence of the COMAND APS multimedia system reduces the vehicle’s weight by an additional six kilograms as a further demonstration of the SLS AMG Coupé Black Series’ uncompromisingly purist character. In place of the screen between the air vents, a carbon-fibre trim element exudes an authentic racing atmosphere. COMAND APS is optionally available ex-factory. The vehicle’s occupants will also discover the motorsport material carbon fibre on the entire centre console with the AMG DRIVE UNIT. Bold highlights are added by red seat belts and red contrasting stitching on the AMG sports bucket seats, the centre console, the upper and lower section of the dashboard and the door panelling. The floor mats similarly feature red edging.
Bang & Olufsen BeoSound AMG high-end surround sound system
A highlight among the optional equipment and appointments is the Bang & Olufsen BeoSound AMG high-end surround sound system, developed by Mercedes-Benz and Mercedes-AMG together with renowned Danish audio specialist Bang & Olufsen. The Bang & Olufsen BeoSound AMG high-end surround sound system with Dolby Digital 5.1 enables an exclusive music experience of the very highest standard. This is made possible by a 1000 W amplifier and 11 loudspeakers in conjunction with precise distribution of the music signals by the sound processor according to the selectable seat positions – driver, co-driver or central. The DSP digital sound processor additionally enables the user to switch between the high-end studio sound (“Reference”) and a surround sound option. All functions are controlled via COMAND APS (optional item) in a special Bang & Olufsen menu. The illuminated 50 W lens tweeters are a special highlight on the dashboard. The 250 W subwoofer is accommodated in the rear shelf. High-quality loudspeaker covers sporting the Bang & Olufsen logo indicate the high-end system’s exclusive character.
Further individualisation options are also available (selection):
AMG carbon-fibre exterior mirror
AMG carbon-fibre engine cover
AMG Interior Carbon-Fibre package
AMG infotainment system (incl. COMAND APS, AMG Performance Media and backup camera)
The market launch of the SLS AMG Coupé Black Series will begin in June 2013.

The performance brand within Mercedes-Benz Cars is presenting a new dream-car: the SLS AMG Roadster. This super sports car thrills with a perfect synthesis of open-top driving pleasure, outstanding driving dynamics and systematic lightweight construction. The overall visual appearance of the new two-seater is marked by its purist design.
The technological highlights of the SLS AMG Roadster read like an A-B-C of modern sports car engineering: the combination of an aluminium spaceframe body, an AMG 6.3-litre V8 front-mid engine with dry sump lubrication developing a peak output of 420 kW (571 hp) and 650 newton metres of torque, a seven-speed dual clutch transmission in a transaxle arrangement and a sports suspension with aluminium double wishbones is guaranteed to make the hearts of sports car enthusiasts beat faster – while ensuring outstanding driving dynamics and roadster motoring pleasure.
The compact fabric soft top of the SLS AMG Roadster opens and closes in just eleven seconds, and can be operated on the move at speeds up to 50 km/h. The new AMG RIDE CONTROL sports suspension with electronically controlled damping is available as an attractive optional extra. It enables the damping characteristics to be modified at the touch of a button. Using the AMG DRIVE UNIT, the driver of the SLS AMG Roadster is therefore able to choose his own suspension setup. Three modes are available: “Comfort”, “Sport” and “Sport plus”.
“AMG Performance Media” is a unique new feature: this innovative multimedia system inspired by motorsport offers an unrivalled combination of numerous telemetric displays such as lateral and linear acceleration, various engine data and lap times on a racetrack, and also features high-speed mobile internet access.
Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and CEO of Mercedes-Benz Cars: “The SLS Roadster is a super sports car, cruiser and highly desirable dream-car all in one. It its distinctive way, it continues the succession of iconic and exciting sports cars from Mercedes-Benz.”
Ola Källenius, Chairman of Mercedes-AMG GmbH: “Systematic lightweight construction, outstanding performance and a breathtaking design combined with sensuous open-air driving pleasure – the new SLS AMG Roadster perfectly embodies the AMG philosophy of German engineering and craftsmanship. The gull-wing model has already thrilled sports car fans all over the world, and now the open-top version is bound to cause a sensation.”
Purist roadster design with perfect proportions
The new Roadster adds a second exciting dream-car to the AMG model family. Head of Design at Mercedes-Benz, Gorden Wagener: “As in the gull-wing model, the purist, athletic design immediately captures the attention. Whether with the roof open or closed, the SLS AMG Roadster is an impressive visual delight!” The perfect proportions are particularly memorable: a long bonnet, the greenhouse positioned well to the rear and a short rear end. Plus the automatically extending rear aerofoil, long wheelbase, wide track and short overhangs – in short, the open-top SLS AMG likewise exudes effortless dynamism and an authentic charisma. The pronounced shoulder sections are reminiscent of tensed muscles, and suggest sheer power in combination with the large wheels in size 265/35 ZR 19 (front) and 295/30 ZR 20 (rear). The attractive metallic paint finish AMG Sepang brown and weight-optimised forged wheels in a 10-spoke design, painted in matt black with a high-sheen rim flange, are available as new optional extras.
Features reminiscent of the 300 SL Roadster, the classic dream-car from the 1950s, include not only the wide radiator grille with its large Mercedes star and the wing-shaped cross-fin, but also the fins on the bonnet and on the vehicle flanks. Like the SLS AMG Roadster, the 300 SL Roadster appeared slightly later than the original gull-wing 300 SL, but unlike in the former case both AMG dream cars are available at the same time.
Interior atmosphere as in an aircraft cockpit
The interior continues the breathtaking design idiom of the exterior, and awakens associations with an aircraft cockpit: prominent stylistic features include the dashboard in the shape of a wing section and the air vents with adjustable, cruciform nozzles reminiscent of jet engines. The extended centre console of matt, solid metal and the new E-SELECT lever in the shape of an aircraft’s thrust control are also design features adopted from the world of aviation. Another discreet, fine detail is the embossed AMG emblem on the leather-lined selector lever.
The AMG DRIVE UNIT – which like numerous other interior features is available in real carbon-fibre – is the central control unit in the centre console: it allows the driver to choose a personal vehicle setup, including adjustment of the AMG RIDE CONTROL sports suspension (optional). The AMG Performance steering wheel with its high-grade nappa leather lining and flattened lower rim section allows perfect vehicle control. The shift paddles and lower steering wheel bezel are of solid metal.
Fully automatic, weight-optimised soft top
The sensual experience in the SLS AMG Roadster is enhanced further when the soft top is open, and the powerful, naturally aspirated eight-cylinder engine with 420 kW (571 hp) and 650 newton metres of torque asserts itself and makes the heart beat faster with its typical AMG eight-cylinder sound. The fabric soft top can be opened and closed while on the move at up to 50 km/h; the fully automatic opening/closing process takes only eleven seconds. The driver only needs to operate the roof control unit conveniently integrated at the front of the centre armrest. When open, the soft top is space-savingly deposited behind the seats in a folded Z-configuration. Three soft top colours – black, red and beige – are available to suit the nine exterior and eight interior colours.
The three-layered fabric soft top is a weight-optimised magnesium/steel/ aluminium construction, and contributes greatly to the car’s low centre of gravity. The soft top has a seamlessly bonded rear window of heated single-layer safety glass. The flush, gap-free transition between the outer roof skin and the rear window keeps wind noise at a low level. A continuous, flexible water pocket running under the soft top catches rainwater and directs it to the underbody via two apertures on each side. The boot capacity is 173 litres with the roof either open or closed, and therefore roughly equal to that of the SLS AMG Coupé (176 litres).
Outstanding material quality and standard of finish
The finest leather, matt-finished solid metal or optional, real carbon-fibre trim create an exclusive ambience and correspond with the authentic feel of the cockpit. Precisely executed decorative and contrasting stitching enhances the visual impression, heightens the hand-crafted look and reflects the attention to detail which is the hallmark of Mercedes design.
The standard appointments of the SLS AMG Roadster include black designo leather, AMG sports seats with heating, a slot-in glass draught-stop, COMAND APS with DVD player, anti-theft alarm system with tow-away protection and interior monitoring, THERMOTRONIC luxury automatic climate control and the KEYLESS-GO starting function. The optionally available AIRSCARF® system exclusive to Mercedes-Benz acts like an invisible scarf warming the head and neck areas of the occupants. It is integrated into the backrests of the AMG sports seats, and blows warm air from vents in the head restraints. The airflow can be adapted for different occupant sizes by means of adjustable louvres, and the level of warmth can be selected in three stages at the touch of a button.
Leather-lined roll-over bars with integrated mesh in a “Silver Shadow” look are available in conjunction with the optional designo Exclusive leather to reduce turbulence in the cockpit. Ambient lighting is integrated into the optionally available, electrically folding exterior mirrors.
Single-tone or two-tone designo leather in espresso brown is available as a new interior colour – this dark shade of brown perfectly matches the new metallic paint finish AMG Sepang brown.
AMG Performance Media and Bang & Olufsen as optional highlights
Another optional highlight is available in addition to the Bang & Olufsen BeoSound AMG surround sound system, which provides exclusive musical enjoyment at the highest level: AMG Performance Media. In an unprecedented way, this system inspired by motor racing combines numerous telemetric displays such as engine data, lateral and linear acceleration and lap times on a racetrack, as well as providing high-speed mobile internet access. AMG Performance Media is activated by pressing the AMG key in the AMG DRIVE UNIT, and operated using the COMAND Controller. Key functions at a glance:
Real-time display of engine oil, coolant and transmission fluid temperature
• Real-time display of engine output, torque and accelerator position
• Real-time display of individual tyre pressures
• Real-time display of acceleration time from 0-100 km/h (alternatively: quarter-mile)
• Real-time display of lateral and linear acceleration combined with braking performance and accelerator position, including memory function
• Recording of individual lap times on a closed-off racetrack, with sector times and memory function
• Integration of DRIVE UNIT functions to save setup data to memory and initiate RACE START
The different functions of AMG Performance Media are shown by the colour display integrated into the dashboard. Three displays are shown at any one time, with the most important information positioned in the centre. Digitally simulated dial instruments with red needles ensure outstanding legibility.
High-speed mobile internet access
AMG Performance Media also provides high-speed mobile internet access: when the car is stationary, the driver and passenger are able to surf the web, download and install apps, and send or receive emails – this unrivalled system has functions comparable to those of a PC, notebook or smartphone. AMG Performance Media uses the widespread, high-performance Android operating system. This exclusive new development will also be installed in other AMG high-performance cars in the future.
Specifically reinforced aluminium spaceframe, low DIN kerb weight
In addition to a high level of occupant comfort, the key factor for driving pleasure in the new SLS AMG Roadster is of course the outstanding performance. The basis for this is the innovative body design: the chassis and body are of aluminium, a design combining intelligent lightweight construction with high strength. With a DIN kerb weight of 1660 kilograms, the Roadster is only 40 kilograms heavier than the Coupé. The result is a remarkable power-to-weight ratio of 2.9 kilograms per hp.
To achieve the same level of driving dynamics despite the lack of a fixed roof, the SLS AMG Roadster has features specifically designed to rigidify the bodyshell, for example side skirts with greater wall thicknesses and more chambers. The dashboard cross-member is supported against the windscreen frame and centre tunnel by additional struts, and a curved strut between the soft top and the tank reinforces the rear axle. The omission of the Coupé roof and gull-wing doors means that the open-top SLS AMG has a reinforcing cross-member behind the seats to support the fixed roll-over protection system. This also accommodates the 250 watt subwoofer of the Bang & Olufsen BeoSound AMG high-end sound system.
All this prevents unwanted vibrations right from the start, and makes it unnecessary to use the additional, weight-increasing vibration dampers that are often found in open-top sports cars. The weight-optimised aluminium spaceframe weighs 243 kilograms, tipping the scales at just two kilograms more than the gull-wing model.
Intelligent material mix and low centre of gravity
50 percent of the intelligently designed, weight-optimised aluminium spaceframe is of aluminium sections, 26 percent of sheet aluminium, 18 percent of cast aluminium and 6 percent of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars.
The entire vehicle concept has been designed to achieve the lowest possible centre of gravity. This applies both to the low connection of the powertrain and axles, as well as to the arrangement of the rigidity-conducive bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torsional connections between the front and rear section and the safety passenger cell, which have been realised consistently using force paths that are as low as possible. This results not only in a low centre of gravity but also in a harmonious and therefore efficient force path in the vehicle structure.
Passive safety at a high level
The aluminium spaceframe provides the basis for outstanding passive safety. The extensive safety features include the fixed roll-over protection system, three-point seat belts with belt tensioners and belt force limiters, and eight airbags: adaptive front airbags and kneebags, two seat-integrated sidebags and two windowbags deploying from the door beltlines.
The optionally available Blind Spot Assist helps the driver with a visual warning symbol and acoustic alert if the danger of a collision with another vehicle is detected when changing lanes.
Powerful AMG 6.3-litre V8 engine with 420 kW (571 hp)
The SLS AMG Roadster has the same, muscular engine as the gull-wing model. The 6.3-litre V8 with a peak output of 420 kW (571 hp) at 6800 rpm makes the open-top SLS one of the most powerful sports cars in its segment. Its power-to-weight ratio is 2.9 kg/hp. This naturally aspirated engine generates its maximum torque of 650 newton metres at 4750 rpm. The open-top SLS AMG accelerates from zero to 100 km/h in 3.8 seconds, and the top speed is 317 km/h (electronically limited) – which means that the Roadster has a performance comparable to the gull-wing variant.
The high-revving V8 engine with a cubic capacity of 6208 cc has the typical characteristics of powerful racing engines. It responds immediately to accelerator movements and is extraordinarily willing. The use of a dry sump lubrication system makes for a considerably lower installed position in the vehicle. The resulting, lower centre of gravity allows high lateral acceleration and ensures thrilling driving dynamics.
Achievement of demanding fuel consumption targets
Despite its uncompromisingly sporty character, very ambitious fuel consumption targets have been met. The SLS AMG consumes 13.2 litres per 100 kilometres (NEDC combined), corresponding to CO2 emissions of 308 grams per kilometre. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimised twin-wire arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimised oil supply and intelligent generator management: during the engine’s overrun phases, kinetic energy is used to charge the battery rather than being wasted by simply generating heat. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine. Sophisticated catalytic converter technology enables current and future emission standards such as Euro-5, LEV 2 and ULEV to be met.
Double-declutch transmission with transaxle configuration and torque tube
The AMG 6.3-litre V8 engine delivers its abundant power to the rear axle via an ultra-light carbon-fibre driveshaft – similar to the setup used in the DTM C‑Class racing touring car. The double-declutch transmission is mounted at the rear (transaxle principle), and connected to the engine housing via a torque tube. A carbon-fibre shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution lie in the rigid link between the engine and transmission and, in turn, the optimum support for the forces and torque generated.
The AMG SPEEDSHIFT DCT 7-speed sports transmission boasts fast gear changes with no loss of tractive force – in as little as 100 milliseconds. The driver has a choice of four different driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) or “M” (Manual). In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. The RACE START function provides optimum traction — as does the mechanical differential lock, which is integrated into the compact transmission housing.
Sophisticated suspension layout with double-wishbone axles
The chosen solution with a front-mid-engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing right through to Formula 1. With a double-wishbone axle, the wheel location and suspension functions remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.
Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminium – substantially reducing the unsprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimetres not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle’s tendency to dive and squat when braking and accelerating. The broad track width – front 1682, rear 1653 millimetres – ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tyres to retain more grip.
New AMG RIDE CONTROL sports suspension on request
The new AMG RIDE CONTROL sports suspension with electronically controlled damping is available as an attractive optional alternative to the AMG sports suspension. It enables the damping characteristics to be modified at the touch of a button. Using a button in the AMG DRIVE UNIT, the driver of the SLS AMG Roadster is therefore able to choose his own suspension setup. Three modes are available: “Comfort”, “Sport” and “Sport plus”. The current mode is shown in the instrument cluster.
“Comfort” delivers a sensitive response with soft damping characteristics, while in “Sport” mode the shock absorbers have a much stiffer response depending on the driving situation. This not leads to better road contact, but also effectively suppresses body roll and pitching. “Sport plus” is ideal for challenging laps on a racetrack: in addition to the higher damping force, this mode comes with specific control algorithms that have been tailor-made for a decidedly sporty driving style on level road surfaces. The new, variable suspension will also be optionally available for the SLS AMG Coupé in future.
Direct steering, differential lock and 3-stage ESP®
The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The SLS AMG comes with 3-stage ESP® as standard, providing the driver with access to the three “ESP ON”, “ESP SPORT” and “ESP OFF” modes at the touch of a button. In “ESP OFF” mode too, operating the brake pedal restores all the normal ESP® functions.
The acceleration skid control (ASR) system’s traction logic is active in all three ESP® modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction significantly – especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.
AMG ceramic high-performance composite braking system available as an option
The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under enormous loads. From now on, red-painted brake callipers all-round are available on request. The newly developed, optional ceramic composite brakes with even larger brake discs guarantee even better braking performance. The ceramic brake discs perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the unsprung masses has further improved both comfort and grip, and the reduced rotating masses at the front axle ensure a more direct steering response.
Lightweight construction was also key when it came to the wheels: AMG light‑alloy wheels based on the innovative flow-forming principle reduce the unsprung masses while improving driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and weight-optimised 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tyres developed exclusively for the SLS AMG ensure optimum performance. A tyre pressure monitoring system is fitted as standard to permanently monitor tyre pressure in all four wheels, with an individual display for each tyre.
Production in Sindelfingen, market launch in autumn 2011
The SLS AMG Roadster was designed and developed in parallel with the Coupé under the autonomous aegis of Mercedes-AMG GmbH. The open-top super sports car will be produced at the largest Mercedes-Benz production plant in Sindelfingen. The AMG 6.3-litre V8 engine comes directly from the AMG engine workshop in Affalterbach, where it is hand-assembled according to the traditional “One man, one engine” philosophy.
The Mercedes-Benz SLS AMG Roadster can be ordered from 1 June 2011, and its market launch commences in autumn 2011.

Carbon fiber, handling and ultra lightweight! That’s the guiding principle of BRABUS for refining the Mercedes SLS AMG. The exclusive sport program comprises aerodynamic-enhancement components made from carbon fiber, ultra-lightweight forged wheels, an electronically adjustable smooth-ride suspension (Ride Control) suspension, a titanium exhaust system with bypass gate, and BRABUS leather.
Extremely light yet enormously strong carbon fiber identical to the one used in Formula 1 racing was chosen as the material for the BRABUS aerodynamic-enhancement components. The components were developed in the wind tunnel. They give the gullwing car an even more striking appearance while optimizing its aerodynamic properties. All components are available either made from clear-coated carbon fiber for a true racing flair or can be painted to match or contrast with the car’s exterior color.
The front fascia of the coupe receives a visual upgrade with the BRABUS front spoiler. But that’s not all: The spoiler further reduces lift on the front axle at high speeds which results in even better directional stability. The two BRABUS covers for the upper air inlets in the bumper lend the SLS an even more striking face while optimizing the cooling air supply.
BRABUS also lends the sides of the SLS a sharper profile. The new air outlets for the front fenders feature a modern design with integrated blue-illuminated BRABUS lettering. The illumination is activated via the keyless-entry remote or by pulling on a door handle.
BRABUS also adds some more visual pizzazz to the rear appearance of the SLS with the BRABUS rear spoiler and the BRABUS rear fascia element that features custom-tailored cutouts for the four exhaust tips of the BRABUS sport exhaust system.
Forged wheels that were custom-developed for the SLS are also elementary for the electrifying BRABUS look. By choosing a staggered tire/wheel combination with diameters of 20 inches in front and 21 inches on the rear axle BRABUS further emphasizes the sporty character of the two-door car. The ultra-light BRABUS Monoblock F PLATINUM EDITION cross-spoke wheels are up to twelve percent lighter than the stock wheels of the SLS and are mounted in size 9.5Jx20 in front and in size 11Jx21 on the rear axle. The extremely wide high-performance tires in sizes 275/30 ZR 20 and 295/25 ZR 21 are supplied by BRABUS technology partners Pirelli and YOKOHAMA.
Another custom development is the height-adjustable BRABUS smooth-ride suspension (Ride Control). It can lower the ride height of the sports car by up to 40 millimeters (1.6 inches). At the push of a button the driver can choose between damper settings that offer a more comfortable or sportier ride compared to the production suspension. To complement this suspension BRABUS will soon offer the BRABUS Front Lift system. It raises the front of the car by some 50 millimeters (2 inches) at the push of a button to safely navigate steep parking ramps or other obstacles.
While engine tuning for the 6.3-liter V8 is still in the final development phase there already is an extremely lightweight BRABUS titanium sport exhaust system with four slanted exhaust tips. The tips have a diameter of 84 millimeters (3.3 inches). This exhaust system weighs 12 kilograms (26 lbs.) or 40 percent less than the production exhaust and adds an extra ten horsepower to the engine’s output. A special feature of this exhaust system is a pneumatically controlled bypass gate that is activated from the cockpit. The normal mode represents a “coming home” sound level that is quieter than the production exhaust. It appeals especially to the neighbors when the SLS returns home late at night. With open bypass gate the eight-cylinder engine sounds even sportier than with the stock exhaust system.
For the cockpit of the two-seater the BRABUS interior designers have developed exclusive accessories and masterfully crafted custom interiors. The speedometer with 400-km/h scale (250 mph) already hints at the car’s future performance with BRABUS engine tuning. An ergonomically shaped sport steering wheel is also part of the BRABUS customization program as are stainless-steel scuff plates with illuminated BRABUS logo and matte-anodized pedals.
The BRABUS upholstery shop creates fully custom interiors for the SLS from top-quality materials. Customers can choose from different types of leather and Alcantara in any desired color and design to suit their individual tastes.
BRABUS can also fulfill individual requests for the trim on dashboard, center console and door panels. BRABUS manufactures carbon-fiber and wood trim sets in any color and with any desired surface finish.
In the matter of individualisation the traditional fine tuner KICHERER has taken on the new AMG Mercedes SLS.
True to the company’s philosophy to only make coherent amendments and to retain the basic form of the AMG, an in essence even more sporty version than the wing-door version was created. Especially the aerodynamics have benefited from a high-class fine tuning. For this the developers developed and mounted a sports spoiler skirt at the front and special diffuser fins on the rear of the vehicle. All new parts designed by KICHERER are naturally made of high quality carbon. A further highlight on the sports car are the 3-part 20 inch RS-1 lightweight wheels. The classic double-spoke design harmonises perfectly with the equally classic sportscar silhouette of KICHERER’s SLS Supersport Edition Black.
For this a sports screw-thread suspension was fitted with a so-called “front-up” system. This enables not only a more sporty driving mode but also suits the sports car very well. In addition it allows the vehicle to be raised at the front at the press of a button so that obstacles such as entries to underground carparks and ?sleeping policemen” can be more easily overcome.
At the rear of the vehicle a KICHERER stainless steel exhaust system with four oval endpipes sonorously eject the exhaust fumes into the open.
An integrated valve control gives the driver – as the occasion demands – the possibility of choosing between a sonorous and a discreet tone.
The KICHERER developers have also tuned the performance screw and thus achieved an every day engine output of 620 PS – instead of the 575 PS of a standard vehicle.
The distinctive name change is based on the special foliation applied to the SLS’ chassis. The matt-black film has no cut edges, is extremely elastic and in addition protects the original varnish from damage or pollution.
So, when all is said and done the KICHERER SLS in the truest sense of the word black, matt and powerful.
Automotive fascination combined with spectacular racing car design – the new Mercedes-Benz SLS AMG GT3. This racing version of the gullwing model was designed as customer sports car for competing in race series according to the near-series FIA GT3 rulebook. Outstanding handling dynamics are ensured by uncompromising lightweight construction and specific modifications to the suspension, brakes and aerodynamics. This very special gullwing model will deliver its debut performance on the racetrack in 2011.
The purist design and breathtaking contours of this gullwing model are effectively emphasised by specific modifications to the bodywork. The new components made mainly from carbon-fibre are an unmistakable testimony to the outstanding racetrack performance and extensive aerodynamic development work.
At the front the GT3 racing car has a new front apron with larger air intakes: the wide aperture below the characteristic radiator grille with a large Mercedes star and a wing-shaped transverse fin supplies the engine oil cooler and brake discs with cooling air. The two air intakes below the vertically arranged bi-xenon headlamps have the same function. Downforce at the front axle is provided by four externally mounted “flics” and the carbon-fibre front splitter: this blends into the smooth underbody cladding which ends with the rear diffuser.
The bonnet has a central aperture to dissipate the engine heat. The hot air is vented in the wheel arches from side vents in the front wings. Particularly lightweight polycarbonate is used to glaze the side and rear windows, and this is also available for the windscreen.
The front and rear wings have been widened to make space for the large racing tyres. With a width of 1990 millimetres, the body of the GT3 is a good 50 millimetres wider than that of the standard SLS AMG. The new side skirts have apertures for cooling the rear brakes. The smooth underbody is visible at the lower edges of the side skirts. The standardised filler pipe for the fast-refuel system is accommodated in the B-pillar. The 120-litre fuel tank is centrally located behind the driver.
Wide rear apron of carbon-fibre
Viewed from the rear, the SLS AMG GT3 impresses with its sheer width. The boot lid is surmounted by a wide carbon-fibre rear aerofoil, which has multiple adjustments and allows a perfect setup for the type of racetrack concerned. The new rear apron features two apertures designed to vent the rear wheel arches. The carbon-fibre rear diffuser is another eye-catching feature: as an extension to the smooth underbody, it gradually rises in the rear axle area and generates a downforce thanks to its shape. The overall aerodynamic concept of the SLS AMG GT3 was refined and finalised in extensive wind tunnel and racetrack tests.
The black exhaust tailpipes emit a thrilling and very characteristic AMG eight-cylinder sound. The rain light prescribed by the rulebook is integrated into the boot lid – it must remain permanently switched on if the weather conditions are poor.
Near-series AMG 6.3-litre V8 engine
As prescribed by the FIA GT3 rules, the AMG 6.3-litre V8 engine is practically identical to that in the standard model. Thanks to its lower weight, the GT3 will easily better the already outstanding acceleration of the standard model – 3.8 seconds from zero to 100 km/h; depending on the final drive ratio, the top speed will exceed 300 km/h.
The AMG 6.3-litre V8 engine also has a dry sump lubrication system in the racing model. Using vacuum and pressure pumps, as well as an external oil tank, makes it possible to dispense with a conventional sump. This technology ensures reliable engine lubrication even under the high lateral acceleration forces encountered on the racetrack.
Dry sump lubrication also allows a low installed position for the V8 engine – one of the key technological highlights of the SLS AMG. Installing the eight-cylinder engine in the lowest possible position behind the front axle as a front-mid engine, and combining it with the transmission in a transaxle arrangement, produces a very favourable weight distribution.
Six-speed racing transmission with sequential gear-changes
Unlike in the standard model, power in the SLS AMG GT3 is transferred by a six-speed racing transmission with sequential gear-changes. Thanks to its compact construction, this race-tested transmission has advantages in terms of packaging – after all, the GT3 version has a smaller ground clearance than the standard model. The driver shifts the gears using two shift paddles on the steering wheel. The transmission is mounted directly on the rear axle, and connected to the V8 engine via a flexurally and torsionally rigid torque tube. This has decisive advantages with respect to handling dynamics, as this sophisticated solution enables the entire powertrain to be configured with far less free play. In conjunction with the traction control sysem, a multi-disc locking differential integrated into the transmission ensures outstanding acceleration. A drive shaft rotates at the engine speed within this torque tube. As in the standard model, and also the Mercedes-Benz C-Class DTM racing cars, the shaft is made from carbon-fibre.
The vehicle concept of the SLS AMG is predestined for top-class racetrack performance, with a long wheelbase, a low centre of gravity and a wide track. Its strengths include precise over/understeer characteristics, first-class agility, low inertia during fast changes of direction and high physical limits when cornering.
Very few modifications were required for perfect racetrack performance: the lowered, lightweight aluminium suspension with double wishbones all-round has the ideal kinematics. Multiple adjustments allow the best possible adaptation to the relevant racetrack characteristics and prevailing weather conditions. Not only the spring and damper setups, but also the track width and camber, the suspension height and the stabilisers at the front and rear axles can be adjusted.
The rack-and-pinion steering system with speed-sensitive servo assistance is basically the same as in the standard SLS AMG. The more direct steering ratio makes for even more agile handling on the racetrack.
AMG motor sports braking system with composite technology
The AMG motor sports braking system ensures extremely short braking distances, outstanding fade-resistance and great sensitivity: race-tested composite technology is used for all the brake discs. In this system, the grey cast-iron discs are mounted on an aluminium bowl via stainless steel connections in a radially and axially floating arrangement. This sopisticated technology allows perfect heat conduction, and therefore reliable fade-resistance. The SLS AMG GT3 also features precisely configured cooling ducts: apertures in the front apron and in front of the rear wheels supply the brake discs with cool air when on the move. All four brake discs are ventilated, grooved and perforated. Six-piston fixed calipers at the front and four-piston fixed calipers at the rear in anthracite with a white AMG logo allow generous brake lining surfaces. An anti-lock braking system with a special racing configuration is standard. For space reasons, the AMG high-performance ceramic composite braking system optionally available for the standard model is not compatible with the 18-inch wheels prescribed by the FIA rulebook.
The size 12 x 18-inch (front) and 13 x 18-inch (rear) AMG light-alloy wheels with central locking are shod with racing tyres in size 287 x 682 mm (front) and 315 x 708 mm (rear). Depending on the conditions, untreaded slicks, intermediates or rain tyres are used. The classic multi-spoke design assists ventilation of the braking system. Rapid pitstops and wheel-changes are assured by the pneumatic jacking system integrated into the underbody: four pneumatic jacks lift the GT3 racing car by around 190 millimetres to allow very rapid wheel-changes by the pit crew.
Interior with racing bucket seat and racing steering wheel
Opening the gullwing doors of the SLS AMG GT3 reveals a functional interior with a racing car atmosphere. The driver is seated in a racing bucket seat, his safety assured by a six-point seat belt and the HANS system (Head and Neck Support), which fixes his helmet in a defined position during an accident to minimise the risk of injury. Additional safety is provided by the steel rollover cage, which also serves to reinforce the aluminium spaceframe.
A racing steering wheel with a diameter of 330 millimetres allows perfect vehicle control. Thanks to the open upper section of the rim, the driver always has a clear view of the central display. This keeps him informed about all the relevant parameters such as speed, engine rpm, operating temperatures, lap times and the selected gear. The steering wheel also has a quick-locking feature which allows much easier access and egress. Switches on the steering wheel boss enable the driver to activate additional functions such as the radio link to the pits, headlamp flasher or the drink function. Further controls are mounted on the centre console, for example the start/stop function for the AMG V8 engine, the traction control system, reverse gear and – if the worst should happen – the integrated fire extinguisher system. The brake balance adjustment control is mounted on the tunnel of the torque tube.
The near-series specification of the GT3 version is reflected in the dashboard, whose powerfully arching wing section gives an impression of width. Strikingly integrated into the dashboard, the air vents galvanised in “Silver Shadow” have adjustable, cruciform nozzles reminiscent of an aircraft’s jet engines.
Deliveries of customer vehicles will commence in spring 2011
The new SLS AMG GT3 was developed to comply with the international FIA GT3 race rules, and is entitled to take part in all GT3 race series – which of course includes the popular 24-hour race in Spa-Francorchamps (Belgium) or the Nürburgring. Interested customers are able to order the GT3 from autumn 2010, and delivery will take place in time for the start of the 2011 racing season. Homologation will be completed in March 2011.

Read the full press release from Daimler below the photo gallery.
The new Mercedes-Benz SLS AMG, which is about to celebrate its world premiere on 15 September 2009 at the International Motor Show (IAA) in Frankfurt/Main, embodies a blend of consummate automotive fascination and high tech. The super sports car delivers a compelling mix of purist styling, consistent lightweight design and superior driving dynamics. At the same time, the SLS fully lives up to all the expectations of hallmark Mercedes everyday practicality and optimum safety. In essence, the new ‘Gullwing’ offers the ideal synthesis of the strengths of Mercedes-Benz and AMG.
The new super sports car from Mercedes-Benz and AMG makes for an alluring proposition with its unrivalled technology package: aluminum spaceframe body with gullwing doors, AMG 6.3-litre V8 front-mid engine developing 420 kW/ 571 hp peak output, 650 Nm of torque and dry sump lubrication, seven-speed dual-clutch transmission in a transaxle configuration, sports suspension with aluminium double wishbones and a kerb weight of 1620 kilograms based on the DINstandard – this superlative combination guarantees driving dynamics of the highest order. The ideal front/rear weight distribution of 47 to 53 percent and the vehicle’s low centre of gravity are testimony to the uncompromising sports car concept. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed of 317 km/h (electronically limited). The fuel consumption of 13.2 litres per 100 kilometres (combined) puts it at the front of the competitive field (all figures provisional).
“Mercedes-Benz is presenting an exhilarating super sports car in the guise of the new SLS AMG, which is bound to set the pulses of all car enthusiasts racing that extra bit faster. The brands Mercedes-Benz and AMG have joined forces to create the SLS AMG– which is set to become one of the most alluring sports cars of all time”, says Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.
“Our customers will experience with the SLS AMG the expertise of Mercedes-AMG, built up over 40 years of motor racing. The unrivalled technology package delivers outstanding driving dynamics coupled with moderate fuel consumption figures – part and parcel of the modern-day AMG,” says Volker Mornhinweg, Chairman of Mercedes-AMG GmbH.
“The styling of the new Mercedes-Benz SLS AMG is not only very special because of the exclusive gullwing doors. Our aspiration is to utilise this interpretation to create the classic of tomorrow and roll out the most alluring sports car of the 21st century. Our aim is also to create a new design icon, which shapes the incomparable legend of our brand, alongside Mercedes models like the CLS or the SL. At the same time, the new SLSpaves the way for the design philosophy of forthcoming Mercedes-Benz sports cars”, says Gorden Wagener, Head of Design at Mercedes-Benz Cars.
Design: purist, distinctive and passionate
The distinctive styling of the new Mercedes-Benz SLS AMG enthrals with its passionate sportiness and reinterprets the breathtaking lines of the Mercedes-Benz 300 SL – one of the outstanding design icons of the Mercedes-Benz brand. With its purist design the new SLS AMG reflects the philosophy of contemporary sports car engineering: the bonnet which measures just under two metres, the low greenhouse positioned well to the rear and the short rear-end with an extendable aerofoil are just as powerful a reminder of the superlative dynamism as the long wheelbase, the wide track and the large wheels. The short overhangs feed through into the proportions, just as does the design of the super sports car with its low-slung front-mid engine set well back and dual-clutch transmission in transaxle configuration. An undoubted styling highlight comes courtesy of the gullwing doors which lend the SLS AMG its incomparable charisma – making a unique statement in this vehicle segment.
The gullwing doors are not alone in rekindling memories of the Mercedes-Benz 300 SL; the hallmark wide radiator grille with the large Mercedes star and the wing-shaped cross fins are a throwback to the front-end of the sports car legend. The three-dimensional, sculptured front-end with its low-set, swept-back front apron set well into the sides lends the ‘Gullwing’ its powerful stance on the road. Six large cooling air intakes and the vertically arranged headlamps set well to the outside with their alluring inner ambience provide a dominant aura: the central bi-xenon low-beam headlamp with its metallic wing section is framed at the top by two LED indicators and the LED daytime driving lights at the bottom.
Influences from aircraft construction
Allusions to aircraft construction come courtesy of the prominent Mercedes star, whose tubular section is reminiscent of the air intake on a jet engine when viewed from the side, as well as the long bonnet: as the eye is drawn forward, so the observer becomes more aware of the curve. The design of the four fins with their Silver Shadow finish that adorn the two air outlet grilles on the end of the bonnet create the same visual impression. These aircraft-style lines also visually accelerate the air that flows past – and make the SLS AMG appear extremely dynamic even while stationary.
The fins on the bonnet are taken up on the vehicle flanks: the connoisseur also discovers here a hallmark styling feature of the 300 SL. The “6.3″ lettering placed between the fins provides a clear reference to the high-displacement naturally aspirated V8 engine. The side air outlet feeds through into a stylistically prominent feature line, which together with the convex flanks and the exhilarating surface treatment, combines aesthetics with power. The compact passenger compartment proves as alluring as it is unmistakable. With its high beltline, low side windows and steeply angled windscreen it comes across as a kind of visor. The forward angled B-pillar with its stylish flowing sweep to the rear window exudes pure dynamism.
Side view dominated by muscle and shoulder
Seen from the side, the eye is drawn to the prominent vehicle shoulder of the SLS, which stretches like a taut muscle from the front to the rear. Distinctive 19-inch (front) and 20-inch (rear) light-alloy wheels fill the wheel arches, which stand out prominently from the sidewall. Three different wheel variants all provide a glimpse of the large high-performance composite brakes. Seen from above, a prominent, uninterrupted line runs from the muscle to the rear. This styling feature is also picked up on the bonnet where the eye follows a distinctive contour which flows over the roof between the gullwing doors, right through to the third brake light.
Rear view that emphasises width
The rear view of the SLS also exudes dynamism and power: the gently sloping boot lid emphasises a sense of width, an impression reinforced by the prominent vehicle shoulder and the sleek tail lights: fitted with LED technology, the horizontally structured lighting units provide a scintillating view. Wing-shaped LED lighting elements ensure a distinctive, enthralling night design. The Formula-1-style LED fog lamp/reversing light is set down low in the centre. Similarly inspired by motor racing are the black diffuser insert and the two chromed tailpipes of the sports exhaust system. The strikingly tapered rear apron provides an unimpeded view of the wide rear wheels, lending the ‘Gullwing’ its self-assured stance on the road. The spoiler integrated in the boot lid is automatically deployed from a speed of 120 km/h to ensure optimum stability at high speeds.
New colours: “AMG ALU-BEAM silver” and two matt finishes
The colour charts for the SLS include nine exclusive paint finishes. The highlight comes in the shape of the unique “AMG ALU-BEAM silver” paintwork: the new, unique process makes the paint shine like liquid metal. The paint covers the body panels like a metallic skin, emphasises the scintillating design lines of the ‘Gullwing’ more strongly than any previous paint job and makes them even livelier by means of targeted light reflections. This effect is made possible thanks to tiny pigments measuring between 30 and 50 nanometres.
The two matt finishes “designo magno allanite grey” and “AMG magno sylvanite grey” are just as eye-catching: with their matt silk surface they reinforce the sporty character of the two-seater through specific contouring of the crease lines.
Interior with allusions to aircraft construction and motor sports practicality
You only need to open the gullwing doors on the Mercedes-Benz SLS AMG and ease into the sports seats to experience a whole new level of interior. The Mercedes-Benz designers took their inspiration from aircraft construction when styling the interior – immediately bringing an aircraft cockpit to mind. The characteristic styling feature is the dashboard, whose powerful and dramatic wing shape makes for an impression of width. Strikingly integrated into the dashboard are the galvanised air vents with their adjustable, cruciform nozzles and Silver Shadow finish – their shape reminiscent of a jet’s engines. The instrument cluster with its LED upshift indicator and two white backlit dial instruments add another decidedly sporty touch with their metallic Silver Shadow finish. The silver dials have red needles and a 360 km/h speedometer scale. As a central feature of the cockpit, the COMAND APSmultimedia system with its 7-inch screen is integrated between the two centre air vents.
The elongated centre console in matt metal similarly picks up on the design theme of the aircraft cockpit. It is home to the AMGDRIVE UNIT, which is inclined towards the SLSdriver and allows them to choose their very own vehicle setup. The E-SELECT shift lever, whose styling recalls the thrust control of a jet, controls the AMG SPEEDSHIFT DCT 7-speed sports transmission. All the controls are made out of solid metal, with a high-sheen Silver Shadow surface.
The concave inner panels of the gullwing doors, the high beltline and the powerful side sill panels round off the cockpit-like impression, while imparting a feeling of sports car-like ergonomics. Fine materials such as nappa leather, solid metal and (optional) genuine carbon-fibre facings underline the pronounced “custom-built” nature of the SLS interior, and show enormous attention to detail. Five different designo leather colours are available to meet individual preferences: black, classic red, sand, porcelain and light brown.
Wide-opening gullwing doors for easy entry
Despite the low sitting position of just 369 millimetres in typical sports car fashion, the wide-opening gullwing doors make it easy to get in and out of the vehicle. At the design stage great attention was paid to the widest possible opening angle – it is a full 70 degrees. Equally importantly, the distance between the open doors and the road surface is a generous 1.50 metres, while the entry aperture between the open doors and the upper edge of the door sills measures no less than 1.08 metres. The entrance height, i.e. the distance between the road surface and the upper edge of the door sills is a very low 45 centimetres. As another important criterion for dignified access and egress, two gas-pressure struts positioned next to the door hinges require only very little pressure when opening and closing the doors – even at very low ambient temperatures.
The gullwing doors require less opening space than conventional coupé doors, and can be fully opened in a normal garage. The door is opened from inside by a handle finished in Silver Shadow. The grip section of the armrest moulded into the interior door panel ensures problem-free door closing. The operating buttons for the power windows, central locking system and exterior mirror adjustment are also located in the interior door panels for easy access. The feeling of comfortable spaciousness is in large measure due to the generous shoulder-room of 1483 millimetres and elbow room of no less than 1606 millimetres. In conjunction with the generous maximum headroom of 990 millimetres and effective legroom for the driver of 1058 millimetres, the result is a low but extremely relaxed seating position. At the same time the intentionally steep angle of the windscreen ensures good all-round visibility for the passengers.
Sports seats with magnesium backrests
The sports seat backrests are made from magnesium, a high-tech material that combines light weight with high strength. This leads to significant advantages where weight distribution and a low centre of gravity are concerned. The sports seats feature so-called two-zone seat cushions. Prominent side bolsters with a harder foam filling provide optimal lateral support, while the inner areas of the seat cushion and backrest are softer for a high level of comfort on long journeys. In conjunction with the Memory package (optional), the fore-and-aft position, seat height, backrest angle, squab angle and steering column are electrically adjustable; three individual settings can also be stored.
Four-way lumbar supports reliably protect the lower spine, while adjustable side bolsters in the backrests effectively improve lateral support on fast bends. Three-stage seat heating and seat occupancy/child seat recognition in the passenger seat are also standard equipment.
The sports seats with integrated head restraints and sporty transverse fluting are upholstered in designo leather – and two-tone seats are also available in classic red, sand and porcelain. If light brown is chosen as an interior colour, the sports seats are upholstered in natural leather with particularly high-quality woven leather on the centre seat panels. Depending on the colour combination, fluorescent or black piping provides another sporty touch.
The Performance leather steering wheel in a three-spoke design has a 365-millimetre rim with a flattened lower section, shift paddles and a metal insert, underlining the authentic custom-built look and ensuring the best possible vehicle control.
A host of stowage space for hallmark Mercedes day-to-day suitability
The interior of the SLS AMG also impresses with the practical stowage space that makes for the day-to-day suitability typical of a Mercedes. The 3.7-litre glove compartment with a spectacles section is integrated into the dashboard on the
passenger side. To the right of the E-SELECT shift lever there is a small stowage tray with a 12 V socket, or an ashtray with cigar lighter. The armrest behind the centre console not only serves to operate the COMAND Controller: at the touch of a button, the armrest can be moved in two stages to reveal a stowage compartment underneath. This has two cupholders and the telephone cradle (optional), and a holder for the ignition key in the rear section. Other items can be stowed on the rear wall between the seats and in the parcel net in the passenger footwell. Two fixed clothes hooks are attached to the seat backrests, while those in the roof liner fold down and are silicon-insulated.
The button to unlock the boot lid is located underneath the light switch. Alternatively the boot can be opened using the ignition key. The luggage compartment can hold up to 176 litres. A made-to-measure luggage set is available as an option, which enables the boot space to be used to full advantage.

Aluminium spaceframe for lightweight design and outstanding strength
The SLS is also breaking the mould when it comes to the body concept: for the first time, Mercedes-Benz and AMG are presenting a car with an aluminium chassis and body. Compared with the traditional steel design, this results in a significant weight saving, clearly illustrated in the DIN kerb weight of 1620 kilograms.
The newly developed bodyshell comprises an aluminium spaceframe. This exclusive design combines intelligent lightweight design with outstanding strength – thus delivering superlative driving dynamics. Lightweight aluminium sections connect the force nodes to a sturdy structure. The large, low-set cross-sections of these aluminium sections ensure high resistance torque, thus providing the required direct transfer of drive, braking and suspension forces. The structure prevents unwanted flexibility; the vehicle responds rigidly, almost without twisting and directly.
45 percent of the intelligent, weight-optimised aluminium spaceframe is made out of aluminium sections, 31 percent out of aluminium sheet, 20 percent out of aluminium cast and 4 percent out of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms – an absolute benchmark in the super sports car segment when compared with the peak output of 420 kW/571 hp.
Low centre of gravity and transverse reinforcing struts for superb dynamism
The entire vehicle concept has been designed to achieve a centre of gravity that is as low as possible. This applies both to the low connection of the powertrain and axles as well as to the arrangement of the stiffness-relevant bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torque connections between the front and rear section and the safety passenger cell, which have been realised consistently using force paths that are as low as possible. This results not only in a low centre of gravity but also a harmonious and, thus, efficient force path in the vehicle structure.
Another prominent feature of the lightweight construction design is the transverse reinforcing struts at the front and rear axle that are integrated into the bodyshell structure. The sections connect the side members precisely where the highest forces act upon the bodyshell under dynamic cornering. The advantages of this sophisticated solution include unrivalled transverse rigidity and the
absence of heavy secondary stiffening or supports.
Passive safety of the very highest calibre
Naturally, the aluminium spaceframe meets all the requirements in terms of passive safety and the hallmark Mercedes-Benz body quality that applies to any car sporting the Mercedes star. The best possible passive safety for the occupants is ensured by the standard-fit three-point seat belts, belt tensioners, belt force limiters and eight airbags: two adaptive airbags and a kneebag each are available for the driver and passenger. Two sidebags integrated into the seats and two separate windowbags that deploy from the door waistline are also available.
Fine-tuned AMG 6.3-litre V8 engine developing 420 kW/571 hp
A powerful eight-cylinder engine manufactured by Mercedes-AMG forms the heart of the new SLS. The fine-tuned 6.3-litre V8 engine develops 420 kW/571 hp at 6800 rpm, turning the SLS AMG into one of the most powerful sports cars in its segment. A power-to-weight ratio of 2.84 kg/hp comes courtesy of the low vehicle weight. The naturally aspirated engine delivers maximum torque of 650 Nm at 4750 rpm. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed electronically limited to 317 km/h (all figures are provisional). Bearing the internal designation M 159, the V8 high-revving engine with its displacement of 6208 cubic centimetres has been thoroughly reengineered compared with the M 156 entry-level engine and boasts all the hallmarks of powerful racing engines.
The principal measures in increasing output include the all-new intake system, the reworked valve train and camshafts, the use of flow-optimised tubular steel headers and the de-throttling of the exhaust system. This results in much better cylinder charging, which feeds through into an increase in output of almost nine percent. The eight-cylinder engine responds swiftly to movements of the accelerator pedal, demonstrating much more pronounced high-revving flexibility across the entire rev range. The switch to dry sump lubrication also translates into a much lower position of the engine in the vehicle. And lowering the vehicle’s centre of gravity has also paved the way for high lateral acceleration and exhilarating driving dynamics.
Perfect synthesis of lightweight design and strength
The use of high-strength components compensates for the increased engine load associated with the higher output. Forged pistons, a reinforced crankshaft bearing, optimised crankcase structure, along with improved lubrication thanks to an on‑demand high-performance oil pump ensure optimum durability. Despite these higher loads, the engine weight for the M 159 has been further reduced. The forged pistons as oscillating masses play a particularly valuable role in this respect, resulting in a kerb weight of 205 kilograms and, in turn, a power-to-weight ratio of 0.36 kg/hp – an unrivalled figure compared with the competition. Sophisticated catalytic converter technology enables current and future exhaust emission standards such as EU 5, LEV 2 and ULEV to be met.
A match for demanding fuel consumption targets
Despite its uncompromisingly sporty character, the demanding fuel consumption targets have been met. The SLS AMGconsumes 13.2 litres per 100 kilometres (combined, provisional figure), earning it a place at the top of the competitor rankings. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimised twin-wire-arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimised oil supply and intelligent generator management: during the engine’s overrun phases and braking, kinetic energy is used to charge the battery, rather than being wasted by simply generating heat. This recuperation assists the driver not only during braking action but also helps convert the braking energy into electrical energy. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine.
Dual-clutch transmission with transaxle configuration and torque tube
The AMG 6.3-litre V8 engine delivers its abundant power via an ultra-light carbon-fibre driveshaft at the rear axle – similar to the set-up used on the DTM C-Class racing touring car. The dual-clutch transmission is mounted at the rear (transaxle principle) and is connected to the engine housing via a torque tube. A carbon-fibre shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution are associated with the rigid link between the engine and trans-mission and, in turn, the optimum support for the forces and torque generated.
A new AMG SPEEDSHIFT DCT 7-speed sports transmission takes care of power transfer. The dual-clutch transmission boasts fast gear changes with no loss of tractive force – in as little as 100 milliseconds. The driver has a choice of four different driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) or “M” (Manual) along with a RACESTART function. In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. Optimum traction comes courtesy of the mechanical differential lock, which is integrated in the compact transmission casing.
Sophisticated suspension layout with double-wishbone axles
The chosen solution with a front-mid engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. The commitment of Mercedes-Benz and AMG to building an alluring super sports car that combines consummate racetrack performance with hallmark Mercedes long-distance comfort has given rise to an ingenious suspension layout. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing, right through to Formula 1. With a double-wishbone axle, the wheel location and suspension function remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.
Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminium – substantially reducing the unsprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimetres not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle’s tendency to dive and squat. The broad track width – front 1682, rear 1653 millimetres – ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tyres to retain more grip. The large caster angle of 11.5 degrees significantly increases negative wheel camber when cornering and also improves tyre grip – this also ensures outstanding stability when braking heavily while cornering.
Direct steering, differential lock and 3-stage ESP®
The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves the feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The ‘Gullwing’ comes with 3-stage ESP® as standard, providing the driver with access to the three “ESP ON”, “ESP SPORT” and “ESP OFF” modes at the push of a button. The result is even more driving pleasure without compromising active safety at all. In “ESP OFF” mode too, operating the brake pedal restores all the normal ESP® functions.
The system’s traction logic of the acceleration skid control system (ASR) is active in all three ESP®modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction notably – especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.
Ceramic composite brakes, innovative flow-forming wheels
The AMGhigh-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under enormous loads. The newly developed, optional ceramic composite brakes with larger brake discs guarantee even better brake performance. The ceramic brake discs will perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the unsprung masses has further optimised the handling of the ‘Gullwing’ – which pays dividends particularly when tackling fast bends on motorways.
Lightweight construction was also key when it came to the wheels: weight-optimised AMG light-alloy wheels – 9.5 x 19 inch (front) and 11.0 x 20 inch (rear) – based on the innovative flow-forming principle reduce the unsprung masses while increasing driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tyres developed exclusively for the SLS AMG ensure optimum performance. A tyre pressure monitoring system is fitted as standard to permanently monitor tyre pressure in all four wheels; individual tyres are shown on the display.
The reinterpretation of the legendary ‘Gullwing’ is scheduled to be launched in spring 2010. The sales price is EUR 177,310 (incl. 19% VAT).
