Chronology
Predecessor	Chevrolet Corvette C5-R
Successor	Chevrolet Corvette C7.R

The Chevrolet Corvette C6.R is a grand tourer racing car built by Pratt Miller and Chevrolet for competition in endurance racing. It is a replacement for the Corvette C5-R racing car, applying the body style of the new C6 generation Chevrolet Corvette as well as improvements to increase the speed and reliability on the track. Since its debut in 2005, it has continued on from the previous dominance of the C5-R in its racing class with multiple American Le Mans Series championships and race wins in the Le Mans Series, FIA GT Championship, and 24 Hours of Le Mans. There are two main versions of the Corvette C6.R: the GT1 version which has 590 HP, carbon-ceramic brakes, and aggressive aerodynamics, and the GT2 version which has 470 HP, cast-iron brakes, and relatively stock aerodynamics with respect to the road car. Unrestricted though, the LS7.R engine will produce around 800 hp.^[2][3] By 2012 the C6.R GT1 was retired from the competition while the GT2 version continues to race around the world.
