TA Class


The Best Continues to Get Better. 

The product of more than 55 years of racing, development and improvement, the TA class remains 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 by monstrous 850 horsepower V8 engines 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.

TA.  No limits. No restrictions. No excuses.  The way racing should be.  

TA Tech

Performance: TA cars are capable of accelerating from 0 to 60 mph in under 3.10 seconds, 0 to 140 mph in under 11.5 seconds and posting mile times of under 10.8 seconds at more than 136 mph. The cars can hit over 190 mph on an extended straight, while braking capability is 70 to 0 mph in less than 130 feet.  

Bodies: Cars must maintain the recognizable external features of the manufacturer’s model while providing the necessary flares for racing slicks. The body is made of composites, including carbon fiber, Kevlar and fiberglass. Multiple bodies are allowed in the TA class, but some headliners are the 6th Gen Ford Mustang, C7 Chevrolet Corvette, Gen 6 Chevrolet Camaro and  Cadillac ATS-V and CTS-V coupes.  

Wheelbase: Standard wheelbase is 102 inches, depending on the model. The maximum overall car width is 80 inches.  

Spoilers/Ground Effects: Front and rear spoilers are allowed, but ground-effects are not.  

Engine: TA cars are powered by a 366 cubic inch, carbureted, overhead valve, naturally aspirated, V8 engine. Engines produce  850 horsepower and run over a thousand miles before a rebuild.  

Suspension: Cars use a coil-over front and rear suspension with a live axle rear end. Active suspension, telemetry, traction control and ABS brakes are not permitted.
