The Penske PC1 was a Formula One racing car developed and raced by Penske Racing during the 1974 and 1975 Formula One seasons. The car was designed by Geoff Ferris, and was raced by drivers Mark Donohue and John Watson. The PC1 entered and competed in 12 Grands Prix, and was replaced by the Penske PC3 in the 1976 season.
Penske Racing (later renamed to Team Penske) was formed in 1968 by successful American motorsport entrepreneur Roger Penske. The team remains the last American team to win a Formula One Grand Prix (the 1976 Austrian Grand Prix).
In 1973, Penske purchased the facilities of small racing car manufacturer McRae Cars Ltd in Poole, Dorset in the UK. McRae Cars had been founded by New Zealand racing driver and constructor Graeme McRae, a globally successful designer and competitor in the F5000 racing formula. Starting with just six employees, Penske appointed his then Porsche Can-Am team manager, Swiss Heinz Hofer, as F1 manager, and Geoff Ferris as chief engineer/designer. Rounding-out the F1 team was Karl Kainhofer, Penske's long-standing chief mechanic and engine builder, who joined the UK operation in mid 1974.
By late summer in 1974, the team unveiled their first car, named the PC1, an aluminium monocoque chassis built around a Ford Cosworth DFV 3.0-litre V8 engine and a Hewland FG 400 gearbox. Penske Racing entered Formula One at the 1974 Canadian Grand Prix held at Mosport Park, Ontario, using seasoned driver Mark Donohue, who had driven for Penske in Indycar before being elevated to team manager of the US Penske operations. Donohue had retired from motorsport at the end of the 1973 season, but returned to full-time competitive driving for Penske in Formula One. Donohue had previously raced in Formula One in a Penske-sponsored McLaren in 1971, competing in two races, the Canadian Grand Prix and the United States Grand Prix.
