The 1992 Camel GT Championship and Exxon Supreme GT Series seasons were the 22nd season of the IMSA GT Championship auto racing series. It was for GTP and Lights classes of prototypes, as well as Grand Tourer-style racing cars which ran in the GTS, GTO, and GTU classes. It began February 1, 1992 and ended October 11, 1992 after fifteen rounds. Taken from http://en.wikipedia.org/wiki/1992_IMSA_GT_Championship_season

The 1992 24 Hours of Le Mans was the 60th Grand Prix of Endurance, and took place on 20–21 June, 1992. It was also the third round of the Sportscar World Championship. For this race, both C1 and FIA Cup class cars ran under the C1 category to comply with ACO rules.
Despite the success of the Group C rules, the FIA introduced new '3.5L' rules for the 1991 World Sportscar Championship which meant a new type of sports-prototype. Taken from http://en.wikipedia.org/wiki/1992_24_Hours_of_Le_Mans.
