Grand Touring Experiential (GTX)[1] is the name of a former classification and set of regulations designated to sports prototypes in sports car racing competing in the IMSA GT Championship, maintained by IMSA between 1977 and 1982. Some cars were based on FIA Group 5 rules; such as the Porsche 935, and some cars were based on FIA Group 6 regulations, such as the Lola T600. Like the original GTO class, the class rules specified turbocharging and supercharging was allowed on engines up to a size of 6.0 L (370 cu in); with engine design and number of cylinders being free and unrestricted. Engines over 6.0 L (370 cu in) were required to be naturally-aspirated.[2][3][4][5]
