GeigerCars supercharges Corvette Grand Sport

 GeigerCars supercharges Corvette Grand Sport
Geigercars Corvette Grand Sport, 1280, 23.04.2010

Top speed of 337 km/h (209 mph)

The Corvette Grand Sport has always looked good, but its performance hasn't necessarily matched the styling - until now.

GeigerCars has unveiled a new performance package, for the aforementioned model, with supercharger (€16,450) and a modified transmission ratio (€2,800).

Thanks to these changes, the 6.2-liter V8 produces 588 hp (438 kW / 596 PS) and 738 Nm (544 lb-ft) of torque - an increase of 158 hp (118 kW / 160 PS) and 163 Nm (120 lb-ft). This enables the car to accelerate from 0-100 km/h in less than four seconds, before topping out at 337 km/h (209 mph).

GeigerCars.de GmbH - 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.

Hey, they stole my idea! Admittedly I only did it on Forza 3, but still... At least they decided to forego a horrible bodykit and the addition of a stupid name.

"The Corvette Grand Sport has always looked good, but its performance hasn't necessarily matched the styling..." Really? I just watched a video w/ Ron Fellows flogging one ofe these cars @ the track. They claim 0-60 in 3.95s. Say what you will about the Vette's lack of panache, bash its interior and raise your snooty euro-noses @ all American cars but don't diss the performance. It makes the author sound dumb.

dude , that what you got out of that statement ? for the record , the California does 0-62 in 3.9 seconds , it's a lot heavier , is more luxurious and only has 460hp.

Scratchy: Having less power and and all that traction enhancing weight, plus a more rearward biased weight distribution that even further aids traction makes for a combination that does wonders for the California's 0-60 times by employing its available power at maximum efficiency. It also helps to have a transmission that, as befitting a $190,000 car, performs magic tricks by shifting faster than the speed of light. In addition I was recently treated to the spectacle of a California blasting away from a stoplight (I quickly rolled down the window to listen to the V8 music). I was quite disappointed actually. It accelerated rather quickly but it was so drama-free, so boring. The front end just pointed at the sky and there was no tire spinning antics whatsoever, same as what an ancient Toyota would do if it had 5 high school kids crammed into the back seat... except with the fast forward button pressed. Speaking strictly of acceleration and ignoring the California's many other fine attributes, I now can't help but think that those who will be driving the California in its natural habitat (a place with many store windows in which to admire one's reflection) will be experiencing the same number of thrills that I did when behind the wheel of a rented Corvette, i.e., zero; that is, until I figured out how to turn the traction control off. The point of my story: Don't buy the California. Buy a ZR1 and an E-Class convertible... and spend the savings on track days and international automobile shipping charges to a distant continent and a twisty dream road of your choice. On second thought, there's probably an AMG that'll satisfy all tire spinning and top down needs, but you probably wouldn't want to compare it to a non-convertible Corvette either due to the apples vs. oranges factor and the also applicable issue regarding the difference in cost. But what have we really learned? Is it that I need to get a life or that I'm REALLY bored of doing my [college] homework on a Friday night? I'm praying that it's the latter. Those who feel inclined to type me a message to tell me it's the former will have a booger flicked into their eye through a really good internet connection.
