The fledgling IMSA GT Series, in no small part due to the efforts of NASCAR supremo Bill France, attracts sponsorship from R.J. Reynolds for the 1972 racing season. Chevrolet with its C3 Corvette and Camaro overcome a large early season lead held by Porsche with an impressive showing in the season finale at Daytona in November to come away with the manufacturers' championship, yet the GTU-classified Brumos Porsche 911S holds off Toad Hall Porsche for its second consecutive putative constructors' title. Brumos driver Hurley Haywood fends off Toad Hall pilot Bob Beasley for his second consecutive drivers' crown and ascend as the all-time career championship leader. The IMSA Trans-Am classification earns overall race victories at Texas (Muniz Mustang) in December 1971 and Bryar (Carter Camaro) in September over the purportedly superior GTO and GTU entries.

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.
