Corvette Grand Sport by GeigerCars
For most of us the Corvette Grand Sport is a perfect car in its standard version, but even a great car can get better. That is, if you have a few thousand dollars in your pocket. The German tuner, GeigerCars has prepared a tuning package for the Grand Sport that improves both the car’s aerodynamics and performance because, hey, the car wasn’t fast enough already.
The 6.2 liter V8 engine has been tuned to deliver an impressive 588 hp at 6,490 rpm and torque of 738 Nm at 4,030 rpm leaving the original and measly 430hp eating its dust. The result is a sprint from 0 to 60 mph in less than 4 seconds and a top speed of 209 mph.
The aerodynamic package includes a wider front fender (obviously to illustrate its engine’s size) and a rear fender with additional vents, a front diffuser, and larger rear spoiler. Overhauled sway bars, shock absorbers and springs, and 18 and 19 inch light alloy rims, with 275/35 and imposing 325/30 tyres round off the powerful package.
Press release after the jump.
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.
