The OPEC oil crisis in 1974 prompts IMSA to cancel the Daytona 24 Hour and Sebring 12 Hour endurance events. IMSA conducts a race event outside North America for the first time at Hermanos Rodríguez in December. Toad Hall Porsche with its new 3.0 911 Carrera RSR secures its second consecutive IMSA putative constructors' title with high finishes in the twin races at Lime Rock in September. Peter Gregg of Brumos and Milt Minter of Toad Hall duel each other all season with Gregg prevailing for his third consecutive drivers' crown, lifting him as the all-time IMSA career championship leader. Departures: Dr. Wilbur Pickett, 44, b. Chevy Chase, Maryland USA 1930, d. plane crash, Deland, Florida USA, June. New Racing Makes: American DeKon.

HeM applies the Putative Model to all racing seasons for two primary purposes: First, to effectively normalize all racing seasons for empirical comparison across the decades, and second, to step clear of series organizers which score season championships primarily out of commercial interest or to attract manufacturer participation. The Putative Model simply scores all seasons in the same fashion as a standard track and field meeting, with the only purpose of tracking what takes place at the finishing stripe If the Putative Champion differs from the nominal Series Champion, please note the (SC) notation below.
