Pratt Miller Motorsports was founded in 1989 by Gary Pratt and Jim Miller as a subsidiary of their company Pratt Miller.[6] In 1997, the team entered a partnership with General Motors and subsidiary Chevrolet to establish a new sportscar racing program based around the Chevrolet Corvette. The partnership resulted in the founding of the Corvette Racing program in 1997.
Since their alliance with General Motors, Pratt Miller have won numerous championships and famous racing events. Corvette Racing has won the 24 Hours of Le Mans nine times, claimed the overall victory at the Rolex 24 at Daytona in 2001, and won seven straight American Le Mans Series championships. Team Cadillac won seven Pirelli World Challenge championships,[7] while The Racer's Group, running Pratt Miller-built Pontiac GTO.Rs,[8] won the Rolex Sports Car Series championship in 2006. GM Racing's Katech-built LS7.R small-block engine was also named the 2006 Global Motorsport Engine of the Year. Katech built the C5-R and LS7.R engines that powered the C5-R and C6.R Corvettes in the GTS/GT1 classes of ALMS and the 24 Hours of Le Mans. Following the 2009 24 Hours of Le Mans, Corvette Racing switched to the GT2 class and decided to bring the engine builds in-house.
