Mainly based in the United States, the series competes on a variety of track types, including road courses and street circuits. Trans-Am is split into TA and TA2 classes for silhouette race cars, while production classes are Grand Touring (GT), Super Grand Touring (SGT), and Extreme Grand Touring (XGT).
The Pontiac Trans Am Series was created in 1966 by SCCA (Sports Car Club of America) President John Bishop. Originally known as the Trans-American Sedan Championship, the name was changed to the Trans-American Championship in 1967 and henceforth. The series actually went by at least twenty different names over the years. Over the years, the series has competed on a variety of different types of racetracks across the country, as well as venues in Canada, Mexico, and even San Juan. The Trans Am series also awards the North Cup and South Cup, which award points in certain races of the national series for competitors who do not run the entire season.
In 2017, Pirelli became the exclusive tire supplier and sponsor of the Trans Am Series, and all classes use Pirelli P ZERO radial ply racetracks. The switch from cross-ply tires to Pirelli P ZERO radial tires was very well received and resulted in higher average speeds and improved lap times in all four classes. Trans-Am will also hold its first race at the recently renovated Charlotte Motor Speedway Roval and the TA2-only race in the opening run of the Music City Grand Prix on the streets of Nashville. However, all the tracks included in the 2020 preliminary calendar are also scheduled for 2021. For the first time in series history, Trans-Am has set up a drop-round system where competitors can choose to drop the worst two-round results, including matches that took place before August 1.
2018 introduced the North Cup and South Cup Regional sub-champions for teams that do not want or are unable to run the full racing schedule and have run a limited number of races in the past. There are very specific requirements for entry into regional championships as these are intended to allow drivers to try to race in the series before running the entire event program. The highest finishing Masters Championship driver in each class will be recognized at the podium ceremony after each race. At the end of the year, the top three Masters Championship pilots in each regional series will be recognized at the series awards banquet.
For the 2021 season, the Trans Am Series has created the Pro/Am Challenge in partnership with the Sports Car Club of America. The Trans Pro/Am Challenge makes the transition between the SCCA Road Racing program and Trans Am much easier by allowing SCCA drivers to compete in Trans Am using the 2021 SCCA road race rulebook for their cars. The various cars are balanced in the right Trans Am class, with minor weight and restrictive changes. The Pro/Am Challenge requires competitors to compete in two special rounds of Pro/Am Challenge and select four other Trans Am Series or West Coast Trans Am Series races to earn points. Points are announced using a similar system as the Pontiac Trans Am Series main championship.
