The 1985 French Grand Prix was a Formula One motor race held at Paul Ricard on July 7, 1985. It was the seventh round of the 1985 FIA Formula One World Championship. It was the 63rd French Grand Prix and the ninth to be held at Paul Ricard. The race was held over 53 laps of the 5.81 km (3.61 mi) circuit for a total race distance of 307.93 kilometres (191.33 miles). This was the last time the entire Paul Ricard circuit was used for the French Grand Prix. In 1986 a shorter, 3.813 km (2.369 mi) 'club' version was used after Elio de Angelis' fatal accident at the circuit during a test session. This was seen as a knee jerk reaction to the crash by the FIA as it was known that the circuit itself wasn't to blame for the crash. The rear wing of de Angelis' Brabham BT55 had broken off at high speed going into the Verriere bends at the end of the pit straight, resulting in a complete loss of downforce at the rear of the car causing it to crash. Nelson Piquet won the race driving a Brabham BT54-BMW. It turned out to be the Brabham team's last victory in Formula One. It was also the first Grand Prix victory since their return to Formula One for Italian tyre manufacturer Pirelli. Piquet won the race by six seconds over pole winner Keke Rosberg driving a Williams FW10-Honda. Third was French driver Alain Prost driving a McLaren MP4/2B-TAG Porsche. Prost's podium finish allowed him to close to within five points of championship leader Michele Alboreto (Ferrari). ==Qualifying== Williams driver, and World Champion Keke Rosberg, broke the Lotus-Renault stranglehold on 1985 pole positions by putting his car on pole position at Paul Ricard, averaging 140.561 mph (226.612 km/h). Ayrton Senna was second in his Lotus-Renault, followed by the Ferrari 156/85 of Michele Alboreto and the McLaren-TAG of Prost. The third row of the grid was taken by the first of the Pirelli runners in Nelson Piquet, while defending World Champion (and 1984 French Grand Prix winner) Niki Lauda (McLaren) rounded out the top six. The factory Renault's of Patrick Tambay and Derek Warwick qualified 9th and 10th. Tambay was driving an updated version of the Renault RE60, dubbed the RE60B, while Warwick was in the older RE60. Nigel Mansell (Williams) had an accident at the high speed Signes corner, located at the end of the 1.8 km long Mistral Straight, during practice, and he suffered a concussion which kept him out of the race. Mansell had broken the record for the fastest accident in Formula One history when he went off at over . The BMW straight 4cyl engine, rated at about , showed its worth on the Mistral Straight, the most distinguishing feature of the Paul Ricard Circuit, when it propelled the Brabham of Swiss driver Marc Surer to a season fastest during qualifying. This compared to the slowest car, the Tyrrell-Ford of Stefan Bellof which could only manage on the Mistral. The French Grand Prix also marked the first time the Tyrrell team used the Renault turbocharged engine with Martin Brundle having use of it for the race mounted in a new Tyrrell 014 chassis while team mate Stefan Bellof still used the Cosworth DFY powered 012. It allowed Brundle to qualify some four seconds faster than his team mate. Brundle telling in qualifying that at one point while both were on a quick lap, he had followed the Bellof's 012 onto the Mistral about 100 yards back, and by the time he reached Signes, Bellof was nothing more than a dot in his mirrors. The top speed of the new turbo powered car was around , some faster than the older V8. Tyrrell were the last F1 team to change from a naturally aspirated engine to a turbocharged engine having done a deal with Renault in late 1984 but the new 014 was not ready until this race. As the lowest team in the Renault pecking order behind the factory team, Lotus and Ligier, Tyrrell were only supplied with Renault's engine, the EF4. 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「1985 French Grand Prix」の詳細全文を読む スポンサード リンク
