The first of the Grand Prix Brabhams made its debut at the German GP in August 1962. The rather chubby turquoise-and-gold car appeared in only five GP but won the non-championship Solitude GP in 1963.
After Motor Racing Developments had produced their run of Formula Junior cars for 1962, attention turned to the company's first GP car. The Brabham BT3 was a totally orthodox affair, an 18-gauge steel spaceframe attached to a Coventry-Climax 1.5 litre V8, a Colotti-Francis Type 34 six speed gearbox and Dunlop tyres. It made its first appearance at the British GP at Aintree in July where Jack Brabham ran it in practice. He raced it for the first time at the German GP two weeks later where he retired. He then finished third at the Oulton Park Gold Cup, fourth at the US GP and then second at the non-championship Mexican GP, a most impressive set of results for the new marque. Brabham built two new BT7s for 1963 but the BT3 was retained as a team spare and used to win the non-championship Solitude GP in July.
Raced by Jack Brabham in F1 in 1962 and retained as a spare car during the 1963 season. Used by Brabham to win the non-championship Solitude and Austrian GPs and also by Denny Hulme for the F1 race at Karlskoga. Sold to Brighton garage owner Ian Raby for 1964 and raced in F1 events fitted with a BRM V8 engine. Retained for 1965 but now used mostly in non-championship events and even in libre racing. To Tony Dean in Leeds at the end of 1965 but sold on quite quickly by him to David Hepworth in nearby Brighouse for hillclimbing. Fitted with a 4.6-litre Chevrolet V8 and used in British hillclimbs in 1966 but without any great success. Sold to John Scott-Davies in February 1967 and then on to Tim Stock a few months later for circuit racing but appeared only rarely. Sold to Fred Opert to be exported to the US but instead sold back to Hepworth who sold it on to Tom Wheatcroft for his museum. Restored (eventually) by 1971 and in Wheatcroft's Donington Museum when it opened in 1973. Ever present in the museum for nearly 40 years until the collection started to be disbanded after Wheatcroft's death. Sold to Marco Rollinger (Luxembourg) in 2012 and prepared for historic racing. Raced by Marco Rollinger at the 2014 Monaco Historics.
