NASCAR
Donohue raced in several NASCAR Grand American races, a NASCAR pony car division from 1968 until 1971. In 1973, driving an AMC Matador for Penske Racing in NASCAR's top division, the Winston Cup Series, Donohue won the season-opening event at Riverside.
That race was Penske's first NASCAR win in a long history of NASCAR participation and remains to this day, the last non-regular (non-full schedule) driver (road course ringer) to win a NASCAR Winston Cup road race.
Although photographs of Donohue with the more aerodynamic 1974 Matador coupe exist and are published, he did not drive it in competition.
