Mark Donohue

Donohue drove the Penske/Sunoco Z/28s to Chevrolet's 1968–69 Trans-Am manufacturer's titles, winning 10 of 13 races in 1968. His book The Unfair Advantage is the primary source for the team's “Team Unfair Advantage” nickname and its meticulous, rules-bending preparation.

After 1969 he and Penske moved to AMC, then to Porsche's Can-Am and F1 programs.
