If you wonder why do tuners tend to upgrade already powerful cars, GeigerCars has the answer: Why be satisfied with the standard while we can give you more?! And they have proved many many times that no matter the make, if it’s American they can turn it into a monster. The latest project by Karl Geiger is the Corvette Grand Sport.

They simply bolt a 2.3 liter supercharger on the car’s 6.2 liter V8 and there it goes! 588 hp and 738 Nm of torque, which translates into mind boggling performance: 0 to 100 km/h in less than four seconds and top speed of 337 km/h.

They also use a couple of high performance parts from Corvette ZO6 to make sure the Grand Sport is able to cope with the extra umpf. Geiger also fits it with bigger brakes and 18 and 19-inch wheels with fatter tires. The asking price for the power package is 16,450 Euros. You can either have this for your 66,000 Euro ‘Vette, or get another car with that money!
