The Ferrari 640 (also known as the Ferrari F1-89)〔(【引用サイトリンク】url=http://formula1.ferrari.com/cars/f1-89 )〕 was the Formula One racing car with which the Ferrari team competed in the season. It was driven by Britain's Nigel Mansell, in his first season with the team, and Austria's Gerhard Berger. The car was designed by John Barnard, and it was the first Ferrari he was responsible for designing. It sported a sharp nose, with a narrow monocoque and bulging side-pods designed to house the radiators with maximum aerodynamic efficiency. It originally had two small air intakes either side of the driver, but from the fourth race of the season in Mexico a more conventional large air intake above and behind the driver was specified. Barnard, who had joined Ferrari from McLaren at the end of the season, had begun designing the car in 1987 with the intent on it being used during the season. However, continual problems with the cars revolutionary semi-automatic gearbox saw the team forced to use the turbocharged F1/87/88C in 1988, with the cars debut pushed back to 1989, the first year of FISA's 3.5 Litre atmospheric formula where turbos were banned. The 640 was powered by Ferrari's Tipo 035/5, a 3.5 litre V12 engine which produced up to by the season end, roughly the same amount of power as the engine it replaced, the Tipo 033A V6 turbo, though without the turbo's fuel consumption worries. This was still down compared to the V10 Honda used by the dominant McLarens which were rated at . The transmission to which it was mated, however, attracted more attention, as it contained the very first semi-automatic gearbox seen in Formula One. In the first half of the season, it proved to be very unreliable, and hampered Ferrari's efforts. However, such gearboxes would become the norm by the mid-1990s. Much of the development work was conducted at Ferrari's private test track Fiorano by test driver Roberto Moreno during the winter season (Moreno also doubled as the lead driver of the rival Coloni team). By the time the Grand Prix circus returned to Europe at the end of June, the problem with the semi-automatic gearbox was found to be not enough power from the battery. With the help of electrical experts from team sponsor Magneti Marelli, the power supply to the gearbox was fixed and the 640's reliability rose accordingly. The car proved to be fast, and Mansell took it to victory in its début race in Brazil, despite fears of unreliability (the potential of the new car, with its innovative aerodynamics, gearbox and V12 engine was clear - Mansell declared on the eve of the Brazilian race that if "the car had even half the horsepower it sounds like it has, we'll win every race this year...."). However, it did not record another finish until the French Grand Prix, and there were to be no races in which both drivers finished. But when the car did finish, it did so in a position no lower than third, with Mansell taking second in both France and his home race at Silverstone, third in Germany (where the long straights saw the Ferrari V12 almost breathless against the more powerful Honda V10s), a second win in Hungary which was highlighted by his passing move on Senna to take the lead, and finally third at Spa, before Berger finished second at Monza, won in Portugal - a race where the Ferraris were clearly more competitive than the championship-winning McLarens - and finished second again in Spain. The carbon fibre monocoque also proved to be very strong, allowing Berger to escape from a fiery high-speed crash at Imola with only minor burns to his hands and a couple of broken ribs. In a 2013 interview, Berger revealed the reason for the crash was the front wing had broken on the car, though as the right front wheel had risen his initial thought was rear suspension failure or a flat left rear tyre. He then revealed that even in the short time it took from the car not responding to the time it hit the wall, he also realised the car was almost full of fuel and could catch fire. From then he was briefly knocked unconscious, but was awake and aware only a minute or so later.〔(2013 Gerhard Berger interview - Imola 1989 )〕 Berger's injuries were enough to keep him out of the Monaco Grand Prix, but with the help of Niki Lauda's physical therapist Willy Dungl, and the semi-automatic gearbox's advantage of not having to take his hands off the steering wheel to change gears, the brave Austrian was able return one race later in Mexico where his injuries would otherwise have kept him out if the 640 had used a conventional gearbox and stick shift. At the end of the season, Mansell was fourth in the Drivers' Championship with 38 points, while Berger was seventh with 21. Ferrari battled with Williams for second in the Constructors' Championship for much of the year but ultimately settled for third, with 59 points. Ferrari lost 2nd in the Constructors' Championship when both Mansell and Berger failed to finish the final two races of the year in Japan and Australia, while both Williams drivers finished second and third at Suzuka, and first and third in Adelaide. For the season, the 640 was replaced with the 641. ==Complete Formula One results== (key) (results in bold indicate pole position; results in ''italics'' indicate fastest lap) 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「Ferrari 640」の詳細全文を読む スポンサード リンク
