2010 Koenigsegg Agera

Koenigsegg is celebrating 15 year of outstanding performance by unleashing their latest creation – The Agera.

Koenigsegg celebrate 15 years of making dream cars, by unleashing their latest jewel – the Koenigsegg Agera. A new supercar aimed to take the Koenigsegg experience to the next level, both on the road and the track.

Agera, the Swedish verb “to act”, has been chosen as the name for Koenigsegg´s latest super creation, as it symbolizes the Koenigsegg philosophy well. Koenigsegg is always striving forward, seeking challenges beyond limitations. The new supercar Agera is an outcome of that creative process and its functions respond very well to the given name.

When we believe in something, we do it. We act. the car also has to act, when commanded to unleash its performance, forcefully and fawlessly. The development of the Agera has been evolutionary, following the Koenigsegg tradition of continuous improvements, by honing and perfecting the end result, all based on previous experience and innovative mindsets. The focus when developing the Agera was to maximize, driving experience, cornering speed, braking and adaptability, says Christian von Koenigsegg.

A testament to time

The Koenigsegg Agera is a testament to time. The original shape and concept of the Koenigsegg CC, created 15 years ago, is still valid, fresh and highly competitive today. The Agera still stay true to the original philosophy, shape and size of the original CC. At the same time, it looks, feels and performs like something belonging to the future, with all new content.

A Supercar is not better than the tires it use, as it is the only link between the road and the car. Therefore Koenigsegg has a deep and long term collaboration with Michelin, when it comes to tire development. The Agera program will take this collaboration to the next level and is expected to set new standards when it comes to overall performance -wet as well as dry handling.

The Agera is as wide at the front as in the rear of the car. This gives very good balance in corners and minimizes body roll.

The Agera also features the latest in braking technology, incorporating an adjustable ABS system, 392×36 and 380×34 ventilated and drilled ceramic discs, for unparalleled braking performance and zero fade regardless of track or road condition.Thanks to optimized breathing and Twin Turbo, power is now 910 hp, running on regular petrol. Torque is maximum 1100 nm and is reached at 5100 rpm. There is over 1000 nm of torque available from 2680 to 6100 rpm.

The new traction control is the fastest reacting in the industry, with auto adapt functionality for different road conditions and driving styles as well as several manual settings.

Koenigsegg has also developed a new type of interior illumination, which is a worlds first in the car industry – Ghost light. The illumination shines through the billet aluminium buttons and surfaces by way of invisible nanotubes, creating excellent visibility of the symbols, as well as a very clean and stylish appearance, framed by an all-new carbon fibre centre console and tunnel assembly.

Furthermore, the driver can easily select the information he wants displayed in front of him, on the all new multi-info cluster combined with the upgraded infotainment display, ranging from basic functionality, to G force meter, power meters, Sat-nav, music, lap-timer or compasses – to best suit the current driving conditions, be it highway cruising, touring country roads, city navigation or serious track driving. Furthermore the interior features the new Agera stitching and seams, which gives an
beutiful fuidity to the interior.

All in all the Agera is created to maintain Koenigsegg’s position as one of the most engaging and top performing cars on the road, on the track -on the planet. Still, maintaining the largest luggage space in the industry and the novel Koenigsegg doors and detachable/stow able hardtop, that really makes all Koenigsegg cars stand out.

The Agera will be produced in parallel to the Award winning CCX and CCXR models. This gives Koenigsegg the ability to live up to our customers varying wishes and demands. The Agera is on display at the 80th Salon International de l’Auto in Geneva. The pre-production show car will be put through its phases for the coming six month prior to the production car launch of the Agera. Finally, Agera is also short for the Greek word Ageratos, which in ancient Greek means “ageless”.

2010 Lamborghini Gallardo LP 570-4 Superleggera

 

Even more dynamic, lighter, more powerful and stunning – the Lamborghini Gallardo LP 570-4 Superleggera is the new top model in the Gallardo line-up. Its evocative “superlight” badge refers to a driving machine of true sporting character and describes a high-performance and lean automotive athlete. The Superleggera makes its entrance to continue the success of its predecessor, launched in 2007, of which Lamborghini produced and sold no less than 618 in just one year.

Compared with the already lean Gallardo LP 560-4, the weight of the Gallardo Superleggera has been trimmed by 70 kilograms (154 lb). The super sportscar from Sant’Agata Bolognese boasts a dry weight of no more than 1340 kilograms (2954 lb) – the lightest road-going model in Lamborghini’s range, and a new arrival in one of the most exclusive market niche segments.

One key factor is the exterior and interior components made from carbon-fiber. Carbon-fiber is ideal for the manufacture of sportscars as its use allows for weight reduction and improved mechanical features. The car’s performance is thus enhanced thanks to a better weight-to-power ratio and reduced total mass, which means that CO2 emissions are also lower. Lamborghini has been at the forefront in this material’s application for many years, and now the brand is extending its leadership even further.

The V10 power unit with 5.2 liters (317,6 cu in) of displacement generates 419 kW (570 CV*) in the Gallardo Superleggera. This puts the weight-to-power ratio of the new top model at only 2.35 kilograms (5.18 lb) per CV and guarantees breathtaking performance. The Gallardo LP 570-4 Superleggera handles the dash from zero to 100 km/h (0-62 mph) in 3.4 seconds and flies past the 200 km/h (124 mph) mark only 10.2 seconds later, ultimately reaching 325 km/h (202 mph). The engine with “Iniezione Diretta Stratificata” gasoline direct injection also boasts an impressive degree of efficiency. Its fuel consumption and CO2 emissions have been reduced by 20,5 percent compared to the previous model.

The Gallardo Superleggera is an uncompromising driving machine. Its running gear, with its mighty braking system, has a dedicated and exceptionally precise set-up, while its 19-inch wheels, Pirelli P Zero Corsa, clad in Pirelli sports rubber, are extremely light. The Lamborghini Gallardo LP 570-4 Superleggera brings a whole new meaning to the term “super sportscar”.

Design and aerodynamics:  The beauty of power

The elegance of every Lamborghini rests on both its extreme power and precise functionality. The Gallardo LP 570-4 Superleggera’s bodyshell is sculptured and completely free from stylistic additions. Dimensions define the contours of a dynamic wedge – 4.39 meters (172,7 in) long, 1.90 meters (74,8 in) wide, but only 1.17 meters (45,9 in) high.

Exterior modifications are all directed at increasing aerodynamic effects. Working closely with wind tunnel experts, the designers from Lamborghini’s Centro Stile remodeled the front bumper – three-dimensional, deeply recessed elements form trapezoidal frames for the large air intakes. Together with the V-shaped, sharply defined nose and the LED daytime running lights, the black elements give the front end a razor-sharp look, reminiscent of Lamborghini’s top model. The new design increases the supply of cooling air and improves the downforce on the front axle.

The modifications to the fully-covered underbody, which include new sill elements and a redesigned diffuser incorporating four large tailpipes, help to achieve better aerodynamic results. The Gallardo Superleggera sports a small rear spoiler as standard. A big rear spoiler is available as an option.

The bodyshell:  Intelligent lightweight engineering

The model on which the Gallardo LP 570-4 Superleggera is based, the Gallardo LP 560-4, is already a prime example of Lamborghini’s lightweight engineering philosophy, with its dry weight of 1410 kilograms (3108.5 lb). Its bodyshell is made from aluminum, with moulded node elements and extruded parts forming an extremely stiff framework into which the aluminum panels are integrated. The spaceframe structure is impact-resistant and forms the basis for the super sportscar’s precise handling.

Against this background, the task of reducing the weight by a further 70 kilograms (154 lb) presented a huge challenge to Lamborghini engineers – the target figure, a weight-to-power ratio of 2.35 kilograms (5.18 lb) per CV, sets a new best among the competition. Lamborghini engineers handled the task as they usually do – with hi-tech competence and aesthetic flair.
The rear windshield and side windows are made from robust and resistant polycarbonate. The engine cover also includes a polycarbonate window, beneath which the V10 engine is displayed like a technical work of art. The long cover section runs from the roof to the rear of the vehicle and is made from carbon-fiber. Engineers also selected carbon-fiber for the rear spoiler, sills, diffuser, parts of the underbody paneling and the fine exterior mirror casings.

With its minimal weight and extremely high rigidity, carbon-fiber is the ideal material for a super sportscar. As far back as the 1980s, Lamborghini was already gathering experience in this field with the Countach. Today, some parts of the Murciélago’s structure are made from carbon-fiber. In order to secure this leading position even further, the brand from Sant’Agata Bolognese established a center of excellence for carbon-fiber materials, where specialists are developing components, working with efficient manufacturing technologies.

Lamborghini’s carbon-fiber strategy is further proven by its foundation of the “Automobili Lamborghini Advanced Composite Structures Laboratory” (ACSL) at the University of Washington in Seattle, USA. Lamborghini provides support to the facility and its long-term, co-operative research work in the fields of aeronautics and astronautics, together with the composite materials’ application within the automotive sector. Alongside the University of Washington, aircraft company Boeing is also among Lamborghini’s partners.
The aircraft manufacturer commands enormous expertise in the field of composite materials. With the new Type 787 Dreamliner, Boeing has developed the world’s first commercial aircraft built entirely from carbon-fibre. Thanks to its superior characteristics, it consumes around 20 percent less fuel than a conventional aeroplane.

The interior and the use of carbon-fiber

Altogether, carbon-fiber components make up 40 (88 lb) of the 70 kilograms (154 lb) saved on the Gallardo Superleggera. In the interior, too, engineers aimed to reduce weight as much as possible. The center tunnel cover, the door panels and the surround of the e-gear automated manual transmission lever are made from carbon-fiber. The high-end material is also used for the sports seats’ shells. They make a significant contribution to the overall weight reduction.

Just like the rest of the cockpit, the sports seats are clad in lightweight Alcantara instead of leather. At Lamborghini, weight reduction is in no way synonymous with sacrifice – the Gallardo LP 570-4 Superleggera is still equipped with air conditioning and electric powered windows as standard.

Lamborghini has built on this strength – the interior is crafted with passionate attention to the tiniest detail; high quality materials indulge both visually and sensually.

The interior, including roof and mats, retains the Lamborghini Gallardo’s black finish. As a contrasting color for elements such as seat trims and stitching, customers can choose among green, yellow, orange and two shades of gray. They match exterior paint finishes in Verde Ithaca, Giallo Midas, Arancio Borealis, Grigio Telesto, Nero Noctis and Bianco Monocerus.

The engine:  10.2 seconds from zero to 200 km/h

In the Gallardo LP 570-4 Superleggera, LP stands for “longitudinale posteriore” and refers to the orientation of the V10 engine – which is mounted longitudinally behind the driver, just like every Lamborghini engine. The number 570 refers to the maximum power output in CV, which equates to 419 kW and is available at 8,000 rpm. Equally impressive is the pulling power – the torque curve peaks at 540 Nm (398,3 ft lbs) at 6,500 rpm. The increase of 7 kW (10 CV) is the result of the new dedicated engine management strategy.

The V10 has a displacement of 5204 cm3 and achieves a specific output of 80.5 kW (109.6 CV) per liter. Special features on this long-stroke engine with an aluminum crankcase include dry sump lubrication and a cylinder angle of 90 degrees. Both solutions lower the center of gravity, thus improving the handling dynamics. To ensure an ideal combustion chamber fill, the engine has an adjustable intake manifold and continuous control of the chain-driven camshafts.

The crankshaft is conceived as a dual-plane crank – the connecting rods of opposing pistons share one bearing. This configuration delivers alternating ignition intervals of 54 and 90 degrees; a unique sequence that is the reason for the compelling, racing car-like sound of the V10. As the revs rise, resounding bass notes are overlaid with razor sharp harmonics.

The powerful V10, combined with the model’s weight reduction, gives the Gallardo Superleggera LP 570-4 breathtaking performance. The car accelerates zero to 100 km/h (0-62 mph) in just 3,4 seconds, 0 to 200 km/h (0-124 mph) in 10,2 seconds – then continues relentlessly to its top speed of 325 km/h (202 mph).

The Gallardo Superleggera is also considerably more efficient – compared with its predecessor, its fuel consumption in the EU driving cycle is reduced by 3,5 liters per 100 kilometer (0,9 gal), or 20,5 percent, to 13,5 liters/100 km (16 mpg). This improvement is partly due to the “Iniezione Diretta Stratificata” gasoline direct injection, which injects fuel into the combustion chambers at pressures of up to 100 bar. The tumbling mix cools the combustion chambers, which enables a very high compression ratio of 12.5:1 which, in turn, increases efficiency.

Power transmission:  Traction without compromise

The Gallardo LP 570-4 Superleggera comes with the e-gear transmission operated via steering wheel paddles, as standard. The automated system with electronic management shifts through its six gears extremely smoothly and far more quickly than could be achieved by human reflexes.

The e-gear control unit has three operating modes, two of which available in automatic. The “Thrust mode” delivers maximum off-the-line performance and is programmed to manage starting revs of around 5000 rpm with minimal wheel slip.

Every single kilometer in the new Superleggera is utterly thrilling – not least because of the relentless traction in practically every situation. This is largely attributable to the four driven wheels, as indicated by the number 4 in the model name.

The permanent all-wheel drive integrates a central viscous coupling and a 45 percent limited slip differential on the rear axle. In normal circumstances, the power delivered by the V10 is channeled with a ratio of 30:70 to the front and rear axles. The weight distribution of the superlight Gallardo is 43/57 percent front/rear.

In 1993, the Diablo VT was the first Italian super sportscar with an all-wheel drive set-up, and Lamborghini has been steadily consolidating its leadership ever since. In fact, thanks to the car’s superior traction, Lamborghini drivers can accelerate earlier out of a bend than drivers of rear-wheel drive cars.

The running gear:  Even firmer, even more precise

The new Gallardo Superleggera is a highly-concentrated driving machine – it thrills with breathtaking cornering speeds and fast, immediate feedback. Its handling is always precise, stable and predictable.

The running gear layout is derived directly from Lamborghini’s motorsport experience. The suspension is aluminum double wishbones. The precise rack and pinion steering keeps the driver very closely connected with the road. The shock absorbers are extremely firm, and the anti-roll bars and suspension mounts have been further reinforced: these features enable the running gear to reach its full dynamic potential. No other model in the Gallardo range is as close to a race car as this one. The development of the Superleggera was heavily influenced by experiences gained from the world’s fastest single-brand race series, the Lamborghini Blancpain Super Trofeo.

Another special feature of the Gallardo Superleggera is the wheels. The 19-inch units are aluminum forged and are therefore extremely lightweight – saving 13 kilograms (28.6 lb). The wheel bolts are made from titanium and are also incredibly light and rigid. The tires are 235/35 ZR19 at the front and 295/30 ZR19 at the rear and come from the Pirelli P Zero Corsa series. Developed specifically for the new top model in the Gallardo range, they are closely related to pure race rubber.

Behind the huge wheels are brakes that serve to deliver uncompromising stopping power and are managed by the standard-fit ESP stability control system. The front wheels are served by aluminum eight-piston calipers, with four-piston units at the rear. The ventilated brake discs have a diameter of 365 and 356 millimeters (ø 14.37 x 1.34 in and 14.02 x 1.26 in) respectively. As an optional extra, Lamborghini can fit extremely fade-resistant and lightweight discs made from carbon-fiber ceramic with six pistons at the front. The front ceramic discs have a diameter of 380 millimeters (ø 15 x 1.5 in).

Equipment:  Hi-tech for road and track

Alongside its specialized carbon-fiber lightweight components, the Lamborghini Gallardo LP 570-4 Superleggera is delivered ex-works with an array of other high-end features. Highlights include the e-gear transmission – a manual gearbox is also available at no additional cost – the dedicated set-up, the Pirelli sports tires and the sports seats. Alcantara upholstery and a hand-stitched steering wheel also set the interior ambiance.

The range of special equipment is particularly sporty. It includes carbon-fiber ceramic brake discs, four-point seat belts, fire extinguisher and a steel roll cage. Visual impact can be further increased by a rear spoiler and the engine bay for the engine compartment – both from carbon-fiber – as well as colored brake calipers.

For the interior, Lamborghini offers special floor mats and leather steering wheels, a storage package and an alarm system. An additional carbon-fiber package includes center console and instrument panel trim, the parking brake handle, parts of the steering wheel and the door handles. A LED light package illuminates the engine compartment, the interior, and the entry area.

Additional features of special equipment increase comfort, such as the multimedia navigation system, the lifting system which raises the front of the car to enable driving over obstacles, a remote control for opening garage doors and a rear view camera mounted beneath the rear spoiler. Customers who want to personalize their Gallardo LP 570-4 Superleggera, can use Lamborghini’s wide-ranging options of the “Ad Personam” individualization program.

2010 Lotus Evora 414E Hybrid Concept

The Lotus Evora 414E Hybrid, so-named because this latest environmentally-focused technology demonstrator from Lotus Engineering produces 414 PS (306 kW) of power, promises breathtaking performance from a highly efficient propulsion system. The concept showcases new developments in plug-in, range-extended electric propulsion, new electronic technologies to enhance driver involvement, the adaptability of the Lotus Versatile Vehicle Architecture (VVA) that underpins the Evora 414E Hybrid and a dramatic new roof system and interior concept from Lotus Design. Through all of these aspects it ultimately demonstrates the exceptional ability of Lotus Engineering to integrate and develop advanced technologies for exciting, efficient, high performance niche vehicles.

The range extended electric drive of the Evora 414E Hybrid consists of two electric motors driving each of the rear wheels independently via single speed geartrain, integrated into a common transmission housing, thus enabling torque vectoring for stability control of the vehicle. Electrical power is stored in a lithium polymer battery pack optimised for energy density, efficiency and high power demand, mounted in the centre of the vehicle for stability and safety. Additional range is provided by the Lotus Range Extender engine, an optimised 1.2 litre, three-cylinder engine, designed specifically for series hybrid vehicles. The drivetrain is designed to combine astonishing performance with efficient, low emissions driving.

Driver involvement is enhanced by the incorporation of HALOsonic Internal and External Electronic Sound Synthesis technologies from Lotus and Harman International, which provide sound contouring within the cabin and improve pedestrian safety outside the vehicle. Integrated with the HALOsonic technology, the Evora 414E Hybrid also showcases a brand new technology from Lotus Engineering, a sports mode that simulates a 7 speed, paddle shift transmission that combines exceptional driver involvement for a hybrid sports car and optimised energy recuperation.

The Evora 414E Hybrid has been designed to highlight Lotus’ innovative electric and hybrid vehicle technology without distracting from the pure sportscar character of the Evora. The solution is innovative, instantly recognizable, beautiful and sporty. It demonstrates Lotus DNA.

Dr Robert Hentschel, Director of Lotus Engineering said: “Innovation has always been at the heart of Lotus and is needed now more than ever. The Evora 414E Hybrid is the perfect demonstration of Lotus Engineering’s core competencies: lightweight architectures, efficient performance, electrical and electronics integration and driving dynamics. The technology demonstrator represents an encapsulation of the advanced technologies that Lotus Engineering continues to develop to overcome the current environmental challenges facing the automotive industry and showcases the future direction that the sector is taking and why Lotus Engineering is perfectly placed to lead the technological development in this area.”

The Drivetrain

For the Lotus Evora 414E Hybrid, Lotus Engineering has developed a highly efficient, high performance drivetrain system consisting of twin motors each limited to providing 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque to each wheel via independent, single speed, reduction transmissions integrated into a single housing, enabling torque vectoring dynamic control of the vehicle.

The vehicle energy storage system is made up of the latest Lithium Polymer battery chemistry providing 17 kWH energy storage capacity. The battery pack is optimised for energy density, efficiency and high power demand, with over 100 kW discharge capability.

The Lotus Range Extender engine provides 35 kW (48 PS/47 hp) of power at 3,500 rpm via the integrated electrical generator and features an innovative architecture comprising an aluminium monoblock construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. This results in reduced engine mass, assembly costs, package size and improved emissions and engine durability. The engine uses an optimised two-valve, port-fuel injection combustion system to reduce cost and mass and can be operated on alcohol-based fuels and/or gasoline. The generator converts mechanical energy to electrical energy to replenish the battery pack charge and provides additional vehicle range in a small light weight package. The generator is also used as a motor to start the range extender engine. The low mass of the range extender unit (85 kg) and compact package makes it ideal for the series hybrid drivetrain in the Evora 414E Hybrid.

All the operation and management of the range extender engine, the power management of the batteries and motor control are controlled by Lotus’ electronic control units and software systems. Full energy management of all the operating systems is the key to maximising performance and operation while minimising energy consumption and CO2 emissions.

For everyday commuting journeys, up to 35 miles can be travelled using battery power. The battery can be charged overnight using a conventional domestic mains supply through a socket concealed by the rear number plate. This permits the vehicle to operate with zero tailpipe emissions. For longer journeys, exceeding the battery capacity, the highly efficient range extender engine is used as a generator to supply the motor with electrical power and top up the battery.

Lotus has used its own vehicle simulation tools to determine the size, capacity, power and performance of all the components in the drivetrain system to optimise the system operation. Overall this is far more energy efficient, weight efficient and cost effective than fitting the vehicle with a larger and more expensive battery, which for the majority of short journeys is a redundant weight, which increases energy requirements. With regard to the total lifetime CO2 emissions of the vehicle, including the energy required to manufacture and run it, the range extender solution has a lower overall CO2 footprint than a fully electric car of comparable performance and operating range running with a larger battery.

The Package

The Lotus Evora 414E Hybrid structure is the same award-winning, versatile vehicle architecture used on the Lotus Evora. The low volume architecture was designed with the upmost flexibility in mind. The Evora 414E Hybrid is a perfect example of how to integrate a compact packaged drivetrain, with excellent performance and range, while using this underpinning. The complete chassis has remained unchanged from the Evora which maintains the structural integrity and strength performance of the original car.

The structure progresses the Lotus ‘bonded and riveted’ technology with new and unique extrusions and folded panels, whilst providing production build modularity and lower cost repairs. The chassis has been designed for scalability so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness vastly increases the number of vehicles that can be developed from this vehicle architecture.

Driving Dynamics

The Lotus Evora 414E Hybrid offers exhilarating, all-round dynamic performance and takes advantage of Lotus developed torque vectoring dynamics. Torque vectoring, which is the capacity to generate different torques at each of the driving wheels, is particularly suited to electric vehicles and significantly reduces the conflict between stability and response.

A key benefit of separate motors to drive each rear wheel individually is that this facilitates a much higher level of vehicle dynamics control. Driving the wheels with different levels of torque can not only generate all the capabilities of a conventional ESP system using energy regeneration as opposed to brake application, but it can also actively drive each wheel forward at different rates, producing a turning moment at the rear of the vehicle in addition to the steering input.

This can be used to enhance low speed manoeuvrability and ease of parking but can also be used to produce a much greater level of straight line high speed stability. Incorporating lateral sensors the system also provides stability control capabilities and levels of steering response normally only associated with heavy and expensive rear steer systems. This can provide automatic correction of both understeer and oversteer characteristics. In addition, the standard method to provide high speed stability of designing the rear wheels to toe-in is not required as the torque vectoring system automatically provides this stability control, with toe-in increasing rolling resistance, lowering fuel economy and increasing tyre wear. Lotus‘ long history of active suspension control provides the core capability to develop this technology and provides extraordinary driving pleasure on the Evora 414E Hybrid.

Driver Interaction

The Evora 414E Hybrid provides less of a psychological step change for people familiar with high performance cars compared to other electric and hybrid sports cars. The car has a simulated paddle shift gear change offering ultra quick gear changes reminiscent of a dual clutch transmission, while actually single speed. This enhances the driver interaction with the vehicle and provides a driving experience similar to current internal combustion engine high performance sports cars. The Evora 414E Hybrid uses a column mounted paddle shift to simulate the gear change and a synthesised engine sound changes frequency with virtual gear selection. The drive torque is also modulated to simulate a physical feeling of a gearshift jolt.

The virtual gearshift simulation, like a conventional gearbox, is used to change the driving characteristics and response of the vehicle. The most significant aspect that this offers the driver is the ability to control the vehicle deceleration by simulating engine braking through a virtual downshift in gears. Unlike true engine braking, the Lotus system does not dissipate the energy of the moving vehicle through internal engine friction but uses the electric motors to regenerate the energy back into the battery. While many electric and hybrid vehicles provide engine braking, this is generally at a fixed rate or preselected rate. In some driving situations this can either be too aggressive, slowing the vehicle unnecessarily, or too light, requiring additional braking application. The Lotus system effectively allows the driver to select the appropriate level of regeneration by simulating stepping down by one, two or even three gears. The simulation of engine braking through both the gear noise change and the retardation of the vehicle is fully intuitive to a driver familiar with a conventional gearbox. The simulated gearchange capability can be selected for greater driving involvement or switched off for more relaxed driving.

The Evora 414E Hybrid uses the Lotus Engineering and Harman International developed HALOsonic suite of noise solutions. The first of which is Electronic Sound Synthesis. This generates engine sounds inside the vehicle through the audio system where it provides an exciting sports sound in line with the brand and nature of the vehicle together with a high level of driver feedback in an intuitive manner. In addition, it also generates sound on the outside of the vehicle through speakers mounted at the front and rear to provide a warning to increase pedestrian safety, which is especially important for electric and hybrid vehicles which can be difficult to hear at slower speeds.

There are four driver selectable engine sounds currently on the vehicle, two of which have been designed to have characteristics of a multi-cylinder conventional V6 and V12 engine. There is also a futuristic sound and a combination of a conventional engine and a futuristic sound, enhancing the brand identity of the vehicle as a step forward in electric vehicle design.

The addition of this Lotus patented simulated gearshift concept not only provides for an exciting and involving driving experience that customers would expect from a Lotus, but also enhances the driver’s control of the vehicle while providing the capability for more efficient operation through a greater use of energy regeneration.

The Design

The distinctive colour scheme and ‘floating’ roof have been carefully designed to accent the cars electric vehicle technology whilst complementing the iconic lines of the Evora.

Copper, a colour often associated with electrical systems, has been chosen for the car’s exterior and interior. A contemporary satin finish paint is complemented by electrical circuit inspired graphics that highlight the car’s key feature lines and the unique glazed roof panel. The newly extended glazed zone integrates seamlessly with the existing forms of the Evora whilst showcasing the key components behind the hybrid and electric vehicle technology.

The signature copper theme is consistently carried throughout the car from the dramatic seat stripes and instrument panel inserts to the copper callipers that nestle behind the carbon grey forged wheels. Inside the cabin a sense of quality and richness has been created by carefully juxtaposing the different tactile qualities intrinsic to leather, Alcantara and metal.

2010 Abt Audi R8 GT R

Sure, the R8 is no lame duck, and this is even more so once the sports car has been tuned by ABT Sportsline. The result is a real model athlete, which does not just ooze power, but also doesn’t have a single gram of fat on its body. With the limited version R8 GT R (with only 25 units available) engineers and designers have gone one logical step further: experience from motorsport flowed into the design, and all the components have been systematically trimmed to ensure a light-weight construction and optimal weight distribution. As a result not just the bonnet, front and rear aprons, the adjustable rear wing or the tailgate are made of carbon, but the outline edge on the rear, the external mirrors and the door panel are also made of the same material. The side windows are made of Makrolon – the high-tech polycarbonate does not just reduce weight, but also has impressive strength properties. The result: the ABT R8 GT R is a proud 100 kilos lighter than its series counterpart.

How much motorsport the team, which comprises the current winners of the DTM and the ADAC GT Masters, actually brings to the road can be seen from the details: Recaro racing seats, a 4-point seat belt system, stainless steel roll-over bar with seat belt attachment, hand-held fire extinguisher or an ABT Sports steering wheel made of carbon – the people at ABT have thought of everything. “The R8 GT R is an uncompromising racing car for the road, and provides maximum performance”, states Christian Abt. The successful motorsport racer indicates his responsibility for the development of this extraordinary vehicle and is impressed with the result. “I recommend trying the GT R on a racing track from time to time, as the car is great fun to drive there”, says the General Manager of ABT who is responsible for technology. The adjustable front panel allows sports inserts; the ABT driver overalls, helmet, racing shoes and gloves are just as much as part of the effective GT R special equipment as an on-board video system and the expandable data module.

The well-trained sports car has enormous performance potential: instead of the series-standard 525HP (386 kW), the 5.2 FSI in the ABT R8 GT R provides a massive 620HP (456 kW) and as a result the light car travels extremely quickly: the top speed is 325 km/h, it does 0-100 km/h in just 3.2 seconds and the GT R reaches the 200km/h mark in a mere 9.9 seconds. In order to ensure that the power can be optimally applied on the road and on the race track, height-adjustable ABT Sports suspension and adjustable dampers are standard on the ABT R8 GT R. The ceramic brake system with modified brake pads has been adjusted to meet the enormous performance potential of the super sports car. The extremely light ABT CR alloys round off the package. On the front axle they are mounted in 9×19 inch and on the rear axle in 11×19 inch. The Michelin sports cup tyres are the perfect choice for the car. The ABT R8 GT R is a unique vehicle which provides maximum driving enjoyment. It has been designed for driving at the limit: from the weight-optimised exhaust unit to the ABT Titanium special coating – ABT’s love of motorsport can be seen in every detail.

2010 Abt Audi R8 Spyder

The R8 Spyder is not just a cabrio, it is a teasingly beautiful open-top sports car of the top class, a real dream car – in particular ABT Sportsline’s version. Their designers have contoured the lines of the open-top model athlete, and using the ABT R8 Spyder has redefined the word “roadster” with Bavarian thoroughness: the result is a vehicle whose power can be seen even when it is at a standstill. The front grill, front apron, side sills and rear apron with the rear spoiler as well as the dual-colour coated ABT BR alloys have been adjusted to the dynamic design of the car. As with the closed R8 versions from ABT, the team has designed all the components in order to achieve the sports car’s optimum distribution of weight; all the parts are therefore made from carbon. As a result the performance can be converted into a maximum of driving enjoyment. Anyone who wants to systematically reduce the weight of their Spyder should use the new ABT CR Superlight alloys, as they also excellently suit the character of the ABT R8.

The V10 with 5.2 litre cubic capacity is used in the ABT R8 Spyder: this provides 600 well-trained horses (441 kW) – while in the series version there are 525HP (386 kW). The Spyder is able to sprint from 0 to 100km/h in just 3.8 seconds and achieves a top speed of 320 km/h. The roadster is therefore a hurricane for the road, giving lovers of fresh-air a new “tangible” term. Suspension springs from ABT provide even better handling, which in particular has a positive effect in the threshold regions of the Spyder. In addition the lower centre of gravity gives the mid-engine sports car an even more aggressive appearance. When you take a look at the car you can see that it is one of the fastest of the fast – and is really ready for anything, as you would expect from an ABT R8.

2010 Mercedes-Benz SLS AMG…The Gullwing is Back!

 

The Gullwig returns as the 2010 Mercedes-Benz SLS AMG on September 15th at the International Motor Show (IAA) in Frankfurt, Germany. Combining stylings of Gullwings past and the sleek stylings on today the SLS AMG delivers a rolling work of art with a 0-62 mph time of 3.8 seconds. The SLS AMG will go on sale next spring with a rumored US price tag of around $260,000.

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).
