Formula III

Formula Three, also called Formula 3 or F3, is a class of open-wheel formula racing. The various championships held in Europe, Australia, South America and Asia form an important step for many prospective Formula One drivers. Formula Three has traditionally been regarded as the first major stepping stone for F1 hopefuls – it is typically the first point in a driver's career at which most drivers in the series are aiming at professional careers in racing rather than being amateurs and enthusiasts. F3 is not cheap, but is regarded as a key investment in a young driver's future career. Success in F3 can lead directly to a GP2 seat or even a Formula One test or race seat.

Formula Three (adopted by the FIA in 1950) evolved from postwar auto racing, with lightweight tube-frame chassis powered by 500 cc motorcycle engines (notably Nortons and JAP speedway). The 500 cc formula originally evolved in 1946 from low-cost "special" racing organised by enthusiasts in Bristol, England, just before the Second World War; British motorsport after the war picked up slowly, partly due to petrol rationing which continued for a number of years and home-built 500 cc cars engines were intended to be accessible to the "impecunious enthusiast". The second post-war motor race in Britain was organised by the VSCC in July 1947 at RAF Gransden Lodge, 500cc cars being the only post-war class to run that day. Unfortunately the race was a complete flop, as three of the seven entrants were non-starters, and, of the four runners, all but one were out of it in the first lap, leaving Eric Brandon in his Cooper Prototype (T2) trailing round to a virtual walk-over at the unimpressive speed of 55.79 mph, though his best lap (which was the fastest recorded for any 500) was 65.38 mph.
