The Brabham BT19 is a Formula One racing car designed by Ron Tauranac for the British Brabham team. The BT19 competed in the and Formula One World Championships and was used by Australian driver Jack Brabham to win his third World Championship in 1966. The BT19, which Brabham referred to as his "Old Nail", was the first car bearing its driver's name to win a World Championship race. The car was initially conceived in 1965 for a 1.5-litre (92-cubic inch) Coventry Climax engine, but never raced in this form. For the 1966 Formula One season the Fédération Internationale de l'Automobile (FIA) doubled the limit on engine capacity to 3 litres (183 cu in). Australian company Repco developed a new V8 engine for Brabham's use in 1966, but a disagreement between Brabham and Tauranac over the latter's role in the racing team left no time to develop a new car to handle it. Instead, the existing BT19 chassis was modified for the job. Only one BT19 was built. It was bought by Repco in 2004 and put on display in the National Sports Museum in Melbourne, Australia, in 2008. It is often demonstrated at motorsport events. ==Concept== The BT19 was created by Australian designer Ron Tauranac for the Brabham Racing Organisation (BRO) to use in the 1965 season of the Formula One motor racing World Championship. The BT19, and its contemporary the Lotus 39, were built to use the new FWMW flat-16 engine from Coventry Climax. Only one example of the BT19 design was built, and it never raced in its original form. Climax abandoned the FWMW's development before the end of 1965, their existing FWMV V8 engines proving powerful enough to propel Jim Clark's Lotus 33 to seven wins and the drivers' championship.〔Lawrence (1998) p.103〕 For 1966, the engine capacity limit in Formula One was doubled from 1.5 litres (92 cu in) to 3 litres (183 cu in).〔Nye (1986) p. 20〕 It was not feasible to enlarge existing 1.5-litre engines to take full advantage of the higher limit and Climax chose not to develop a new 3-litre motor, leaving many teams without a viable engine for 1966.〔 The new 3-litre engines under development by competing team Ferrari had 12 cylinders.〔 Jack Brabham, owner and lead driver of BRO, took a different approach to the problem of obtaining a suitable engine. He persuaded Australian company Repco to develop a new 3-litre eight-cylinder engine for him, largely based on available components;〔Henry (1985) p. 53〕 the engine would produce less power than Ferrari's, but would be lighter, easier to fix and more fuel efficient. Brabham cars were designed and built by Motor Racing Developments Ltd. (MRD), which was jointly owned by Tauranac and Jack Brabham and built cars for customers in several racing series. The Formula One racing team, BRO, was a separate company wholly owned by Jack Brabham. It bought its cars from MRD but Tauranac had little connection with the race team between 1962 and 1965.〔Lawrence (1999) p. 31〕 At the end of the 1965 season Tauranac was losing interest in this arrangement, reasoning that "it was just a matter of a lot of effort for no real interest because I didn't get to go racing very much" and "I might as well get on with my main line business, which was selling production cars."〔 Although Brabham investigated using chassis from other manufacturers, the two men eventually agreed that Tauranac would have a greater interest in the Formula One team, which MRD eventually took over completely from BRO.〔Henry (1985) p. 55〕 This agreement was not reached until November 1965. Repco delivered the first example of the new engine to the team's headquarters in the United Kingdom in late 1965,〔Pinder (1995) p. 43〕 just weeks before the first Formula One race to the new regulations, the non-championship South African Grand Prix on 1 January 1966. Rather than build a new car in the limited time available, BRO pressed chassis number F1-1-1965, the sole and unused BT19, into service.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brabham BT19」の詳細全文を読む スポンサード リンク
