5 ZEREX SPECIAL
Always one to seek out the ‘unfair advantage’, Roger Penske pushed the limits of sportscar regulations even before he founded his eponymous team. The Zerex Special was essentially a rebodied Cooper Formula 1 car fitted with a 2.7-litre engine. Penske ran it at the 1962 Riverside Grand Prix and beat Jack Brabham, Graham Hill, Dan Gurney, Bruce Mclaren, Jim Hall and Masten Gregory to win. The Zerex kept on winning until Penske sold it in ’64, after which it played its part in the creation of Bruce Mclaren’s new marque.
