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.Taking performance one step further, the Grand Sport brings in a better suspension package, brakes, and tires. The car is a little heavier than the Coupe, but the road holding capability of this car is without question. It is the easiest to handle in the Corvette range, with excellent tires and sufficient power.
