TRANS AM 101
The Best Continues to Get Better.
The product of more than 30 years of continuous development and improvement, the TA class remains the standard of North American grand touring racing and the flagship of the Trans Am Series, presented by Pirelli, paddock.
TA cars are an unapologetic culmination of unadulterated power and one of the most refined performance platforms available in racing. While countless other formulas have come and gone, the TA class remains, a testament to its ability to not only adapt, but set the pace for road racing everywhere.
Powered forward by monstrous 850-plus horsepower V-8s emitting that iconic roar found only in Trans Am, TA remains a truly unique class and an example of what a purpose-built racecar can do on a pure racing platform.
TA. No limits. No restrictions. No excuses. The way racing should be.
The TA racecar is the ultimate performance machine for road racing in North America, and in order to produce the level of performance needed to live up to that title it takes a purpose built racecar with a lot of custom built parts. For the complete technical section regarding these ultimate grand touring machines consult the SCCA Pro Racing Regulations.
