In 1966, Donohue began a pivotal partnership with team owner Roger Penske, leading to significant successes in the United States Road Racing Championship (USRRC) and the Trans-Am Series. His engineering insights and driving prowess were instrumental in securing multiple championships for Penske Racing. Donohue's achievements extended to the Indianapolis 500, where he won in 1972, setting a record speed that stood for over a decade. He also made notable contributions to Formula 1, driving for Penske's team and earning a podium finish at the 1971 Canadian Grand Prix.
