International Race of Champions

International Race of Champions (IROC) is an auto racing competition, promoted as an equivalent of an All-Star Game or The Masters. Drivers race identical stock cars set up by a single team of mechanics in a effort to make the race purely a test of driver ability. It is run with a small field of invited drivers (6-12). It was created in 1973 by Riverside International Raceway President Les Richter and Roger Penske with Mark Donohue being the first driver to win the championship, in 1974. The cars used that year were Porsche Carrera RSRs. Donohue's win in the fourth and last race of that season was his last win as he died in a Formula One practice the next season. The series was not run in 1981, 1982 or 1983.
