The Corvette C6 was first introduced in 2006 and has three road car variants including the Grand Sport, Z06 and ZR1. Racing variants include the C6.R.In order to surpass the Z06, something drastic had to be done. With the integration of a super-charger to their 6.2L engine, the engineers managed to squeeze out an almost mind boggling 638hp. In doing so, the engine is a little heavier than the Z06 and this additional weight is directly over the front wheels, resulting in a car that is a lot trickier to get the most out of.The ceramic brakes are standard, and are certainly capable of arresting the car when needed. Upgraded tires are also equipped as standard to ensure the car is capable of adequately gripping the road, allowing you to deliver most of that power. The ZR1 is also fitted with a new variable ratio steering rack. Finally, with the PDE performance package, this car is capable of stunning lap times on the race track.
