IMSA GT classes
IMSA GT classes are former classifications of sports prototypes in sports car racing competing in the IMSA GT Championship. The classes were used at different, overlapping times during the period from 1971 to 1998, over which the championship ran.
Grand Touring Over (GTO) is the name of a former classification designated to grand touring cars competing in the IMSA GT Championship, and later by Grand-Am in the Rolex Sports Car Series. IMSA used the class between 1971 and 1991, and Grand-Am used the class for a single season in 2000. The class had its origins in the original "TO" class used by the SCCA in the Trans-Am series, and was also similarly modeled to the FIA's Group 4 and Group 5 racing classes, but eventually evolved over time into its own category. The class specified an engine displacement of more than 2.5 L (150 cu in), with engine design and number of cylinders being unrestricted. Turbocharging and supercharging was allowed on engines up to a size of 6.0 L (370 cu in). Engines over 6.0 L (370 cu in) were required to be naturally aspirated. The original class became known as Grand Touring Supreme (GTS) in 1992.
Grand Touring Under (GTU) was a classification originally used in the IMSA GT Championship, and later by Grand-Am in the Rolex Sports Car Series. IMSA used the class between 1971 and 1994, and Grand-Am used the class for a single season in 2000. The original class rules specified an engine displacement of under 2.5 L (150 cu in), natural aspiration, and was the secondary class below the top-tier class, GTO. The class later became known as GTS-2 in 1995, then GTS-3 between 1996 and 1997, and eventually evolved into the GT3 class for 1998.
All American Grand Touring (AAGT) was maintained by IMSA between 1975 and 1989. These cars were All-American, V8-powered, used a maximum of 5 forward gears, and used a steel tube frame (similar to the type used in the SCCA Trans-Am Series), and were designed to compete against heavyweight European manufacturers and machinery of the time, such as Porsche and BMW, who were dominating the series at the time.
