High Quality Content by WIKIPEDIA articles! The Chevrolet Corvette C5-R is a grand touring racing car built by Pratt Miller and General Motors for competition in endurance racing. The car is based on the C5 generation of the Chevrolet Corvette sports car, yet is designed purely for motorsports use. It became one of the most dominant cars in GT categories, with wins at the 24 Hours of Daytona, 12 Hours of Sebring, and 24 Hours of Le Mans, as well as championships in the American Le Mans Series. The Corvette C5-Rs debuted in 1999 and continues to be raced to this day, although the C5-R has effectively been replaced by the Corvette C6.R.
