The years 1966 to 1972 are widely regarded as the golden age of Trans American (Trans Am) racing, a thrilling period that saw factory-backed muscle cars, legendary drivers, and fierce rivalries come together to create one of the most exciting chapters in American motorsport history. The Sports Car Club of America (SCCA) launched the series in 1966 to promote showroom stock sedans, but what followed was a war between automakers on the racetrack that would shape the identity of American performance cars for decades.
The Trans Am Series was born out of the SCCA's effort to provide a professional road racing series for American-style sedans. It was originally part of the SCCA's new "Sedan Championship" and split into two classes based on engine displacement:
Ford immediately saw the marketing potential of racing Mustangs in a professional series. The company committed to a factory effort, with Carroll Shelby preparing Mustangs and seasoned drivers like Jerry Titus behind the wheel. Ford clinched the inaugural manufacturer’s title in the Over 2.0-liter class, setting the tone for the years to come.
In 1967, the competition intensified. Chevrolet entered the fray with the new Camaro Z/28, engineered with racing in mind. Mark Donohue and Roger Penske formed a formidable team under the Sunoco banner, and their well-prepared Camaros would become legends.
The season saw fierce battles between Ford and Chevrolet, with Mercury also joining through the Cougar brand (prepared by Bud Moore Engineering). Jerry Titus won four races for Ford, helping them to secure a second manufacturer’s championship. Meanwhile, the under-2.0-liter class was dominated by European brands, with Porsche and Alfa Romeo trading blows.
By 1968, Chevrolet's investment in Trans Am began paying off. Mark Donohue, driving for Penske Racing in a Z/28 Camaro, dominated the series by winning 10 out of 13 races. Penske’s team revolutionized pit stops and car preparation, introducing quick refueling and highly disciplined race tactics, giving them a competitive edge.
Ford struggled to match the precision of the Penske operation. Though Mustang remained competitive, the balance had shifted. In the under-2.0-liter category, Porsche emerged as the dominant force, establishing itself as the team to beat.
The 1969 season marked a high point in manufacturer involvement:
Although Donohue again led in wins (six total), Ford’s consistent performance across its teams brought them the manufacturer’s championship. The Mustang-Camaro rivalry had reached fever pitch, capturing the attention of fans and cementing Trans Am's place in motorsport history.

The 1970 season is widely seen as the pinnacle of Trans Am racing. Every major American manufacturer had skin in the game:
This was racing at its most visceral. Parnelli Jones’s aggressive driving style won him five races and the championship, with Ford taking the manufacturer’s title. The season featured epic wheel-to-wheel battles, full factory support, and massive crowds.
Despite Chevrolet pulling back factory support mid-season, Donohue managed to win three races. The muscle car war was at its peak — both on the streets and on the circuits.
Rising costs, corporate shakeups, and waning public interest in large sedans started to erode the foundations of Trans Am racing in 1971. Ford officially pulled out, leaving Bud Moore and Jones without factory backing.
AMC took the opportunity to up its investment. Roger Penske, now allied with AMC, brought Donohue over to drive the Javelin. Their meticulous preparation paid off, with Donohue securing the drivers’ championship and AMC taking its first manufacturers’ title.
The field began to thin, and with less competition, the spectacle diminished. The under-2.0-liter class, once a proving ground for European performance cars, became an afterthought.
By 1972, the golden era of Trans Am was effectively over. Only a handful of factory-backed teams remained. AMC continued to support Penske and Donohue, and they again won the championship — but with diminished fanfare.
The once-glorious fields of fire-breathing muscle cars were shrinking, a casualty of rising insurance costs, the Clean Air Act, and the oil crisis looming on the horizon. The SCCA began changing regulations, opening the series to more exotic machinery and moving away from the pony car focus.
Trans Am would continue as a series, but never again with the same level of cultural relevance or manufacturer involvement that defined 1966–1972.
Despite its relatively brief golden age, Trans Am left an indelible mark on American motorsport and car culture:
Today, vintage Trans Am racing events and restored vehicles from the era are prized by collectors and fans, serving as roaring reminders of a time when muscle cars ruled the road courses of America.
