Mark Donohue was the driver to beat in Trans Am for four seasons, although the record books don’t fully represent Donohue’s greatness as the series only awarded manufacturer championships until 1972. Beginning his career in the series in 1967 driving for fellow inductee Roger Penske, he scored three victories that year. The following season he amassed 10 wins, including a victory in the Trans Am class in the 12 Hours of Sebring alongside Craig Fisher, securing Penske and Chevrolet the 1968 title. Chevrolet took the championship again on the strength of Donohue’s six victories in 1969. Earning three victories in 1970, Donohue brought Penske and new manufacturer AMC the championship in 1971 with seven wins. His record of 29 victories wouldn’t be broken for more than 30 years, and applying the points retrospectively, he would have taken the driver’s championship three times in four seasons.
