The Chevrolet Corvette C7.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 C6.R racing car, using the C7 generation Chevrolet Corvette as a base. The C7 road car was noted to incorporate development from the Corvette C6.R, thus those properties also carry over to the race car. The Corvette Racing C7.R races in the WeatherTech SportsCar Championship in the GT Le Mans (GTLM) class.[1]

Development[edit]

The Corvette C7.R had its official unveiling at the 2014 NAIAS in Detroit.[1] The car made its first testing appearance, in camouflage, at the Rolex Motorsports Union at the Mazda Raceway Laguna Seca track.[2] The car's new livery and details were revealed on January 13, 2014.

The C7.R finished the year in third place behind the Porsche 911 RSR and BMW Z4 GTE and ahead of the Ferrari 458 Italia GT2.[5]
