It has been suggested that this article be merged with Grand Touring Experimental, All American Grand Touring, Grand Touring Over, Grand Touring Under, Grand Touring Supreme and American Challenge to List of IMSA GT classes. (Discuss) Proposed since December 2023.
Grand Touring Prototype (GTP) is the name of a former classification designated to sports prototypes in sports car racing competing in the IMSA GT Championship, maintained by IMSA between 1981 and 1993.[1][2] The early cars were based on the almost same identical ruleset as the FIA's Group C category, but eventually evolved into a separate category. It was the successor to the Grand Touring Experimental (GTX) class, which were based on FIA Group 5 and Group 6 cars.[3][4][5]
The IMSA GTP moniker was revived in 2023 to replace DPi as the top class of the IMSA SportsCar Championship for the merger of DPi and the World Endurance Championship Hypercar class.
