British Formula Three Championship
The British Formula Three Championship was an international motor racing series that took place primarily in the United Kingdom with a small number of events in mainland Europe. It was a junior-level feeder formula that used small single seater Formula Three chassis. Its final official title was the Cooper Tires British Formula 3 International Series. Notable former champions included Jim Clark, Jackie Stewart, Emerson Fittipaldi, Nelson Piquet, Ayrton Senna, Mika Häkkinen, Rubens Barrichello and Daniel Ricciardo.
History
The first Formula Three championship to take place in the UK was the Autosport F3 championship held in 1951, which was won by Eric Brandon. By 1954, it had evolved into a national-level series and was organised by the British Racing and Sports Car Club (BRSCC). This was the 500cc period of Formula Three, which was active in the UK and other countries until 1959, at which point Formula Three was adapted into Formula Junior. In this period, there were often two or three series running concurrently and a single national series had yet to be firmly established.
