2010 GeigerCars Corvette Grand Sport

The name “Grand Sport” is entrenched in the racing history of the Chevrolet Corvette. Now, for the 2010 model year, there is a new edition that evokes memories of the racecars of the seventies – and Geigercars.de has already given these rockets an additional performance upgrade.

With the LS3 V8 under the bonnet, and the corresponding 430 hp and 575 Nm in torque, the Grand Sport is certainly not short of legs when it leaves the factory. But why be satisfied with production line performance, when tuning specialist Geigercars.de can give you something more? Thanks to the Munich pros, a supercharger with a fat 2.3 litres capacity sits on top of the eight-cylinder engine, which itself exhibits a volume of 6.2 litres. The result is a growth in the power of the Corvette to an immense 588 hp at 6,490 rpm, and torque of 738 Nm at 4,030 rpm. This ultimate sports car negotiates the sprint to 100 km/h in less than four seconds from contact, and it’s not until reaching 337 km/h that the Geigercars.de rocket is forced to relent to wind resistance.

The Grand Sport impresses both aesthetically and technically, with wider front and rear fenders with additional vents, to accommodate the larger brakes of the sister model Z06 with its 355 mm, six-cylinder discs at the front axle, and 340 mm, four-cylinder discs at the rear. The front diffuser and larger rear spoiler are also borrowed from the engineers of the Corvette Z06. Sway bars, shock absorbers and springs have also been overhauled in addition to the six-speed transmission, while a dry sump oil system and differential cooler are also on board. The battery of the Grand Sport has been relocated to the rear. Optimum road contact is guaranteed by the 18 and 19 inch light alloy rims, with 275/35 and imposing 325/30 tyres.

Special factory-installed emblems on the front fenders, and not least the special graphics applied by Geigercars.de to the fenders, bonnet and boot lid, draw even the untrained eye to the character of this very special elite athlete – and underline that certain something about the entire project perfectly.

ICONIC CORVETTE GRAND SPORT REBORN

Glories of yesteryear were conceived when General Motors licensed a Californian specialist sports car partnership in early 2009 to resume production of the iconic Corvette Grand Sport, arguably GM’s most prestigious track racer ever.

 Duntov/Superformance LLC lost no time in turning opportunity into reality, and Duntov immediately began production of the race version of the 1963 Grand Sport, which has already raced and won a number of events this year.

 Now the street version of this popular 1960’s muscle car will follow with the series production of a Turn Key Minus chassis by Superformance.  The original Grand Sport – intended to be a “Cobra Killer” – was built by General Motors under the watchful eyes of Zora Arkus Duntov, GM’s chief engineer at the time.

 The value of a continuation model and that of a historic original is encapsulated in its authenticity. Superformance went to great lengths to ensure that the new street version would be as like the original Grand Sport as two peas are in a pod, having acquired the original blue prints and molds off the original #2 Grand Sport.

 With only five originals ever built, the Superformance Grand Sport will give buyers the opportunity to own a piece of GM’s rich history. What makes this street version an even more valuable product is that it is licensed by its originators and that is not only meant to be raced, but is equally at home as a daily driver.

 The SPF Grand Sport will be available in a roadster or coupe version and the technical originality is ensured by the legendary discipline and precision that has made Superformance products the leading fully assembled rolling chassis in the world.

 Each SPF Grand Sport will be professionally engineered, custom crafted and professionally assembled in the largest and most modern privately owned specialist automotive manufacturing facility in the world.

 The design of the Grand Sport chassis enables owners to select their drive trains from virtually any General Motors crate option available. The first completed street version rollers will be available in the US in mid 2010.
