In 1966, the Sports Car Club of America created a new racing series called the Trans-American Sedan Championship, or Trans-Am series. This gave Ford Motor Company another opportunity to build a performance image for Mustang. The Shelby-built cars and teams won championships in 1966 and 1967. Shelby American-built Mustangs earned more victories in the 1968 and 1969 Trans-Am seasons.
Shelby American retired from the series at the end of the 1969 racing season after a very successful four-year run. Along the way, the Shelby American team beat some of the best racing teams of the day, including the Bud Moore factory-backed Mercury Cougar and Roger Penske’s Camaro, heavily supported by Chevrolet.
