The 1987 Brazilian Grand Prix was a Formula One race held on April 12, 1987 at the Jacarepaguá Circuit in Rio de Janeiro. It was the first race of the 1987 Formula One season. It was the sixteenth Brazilian Grand Prix and the eighth to be held at the Rio circuit. It was held over 61 laps of the flat 5.031 km (3.126 mi) circuit for a race distance of 306.891 km (190.70 mi). The race was won by the reigning world champion, Frenchman Alain Prost driving a McLaren MP4/3. It was Prost's fourth victory in the Brazilian Grand Prix, expanding his own record. Prost won the race by 40 seconds over local hero Nelson Piquet driving a Williams FW11B. Third was Prost's new Swedish team mate Stefan Johansson. ==Qualifying== In almost a repeat of , prior to the race there was talk of a drivers boycott due to the FIA's new Super Licence fees for 1987. Previously the fee for a drivers Super Licence had been US$825. However, from 1987 drivers who scored World Championship points in would be required to pay more (i.e. the more points a driver scored, the more he paid for his licence) with drivers such as World Champion Alain Prost and Williams pair Nigel Mansell and Nelson Piquet were all required to pay around $12,000 (while others such as Lotus rookie Satoru Nakajima only had to pay the basic fee). According to the drivers, it wasn't so about the money, it was the principle that a licence is a licence and that the fee should be the same for everyone. However, by the time the cars were ready for Friday morning's first practice session, everyone (or in some cases the teams) had paid the required licence fee. Qualifying was dominated by the Honda powered Williams, with Mansell ahead of Piquet. Third was Ayrton Senna with his Lotus. The Lotus 99T, now in the Yellow and Blue colours of new sponsors Camel Cigarettes, was using the computer controlled active suspension for the first time in the hope that its advantages (keeping the car at the optimum ride height) would give them an edge over the rest of the field. The total number of cars entered for the event was 23, but on race day the March team, who went into the race with a modified Formula 3000 car for F1 rookie Ivan Capelli due to their new car not being ready, ran out of Cosworth DFZs, blowing their last in the Sunday morning warm-up and there were only 22 starters. Qualifying also saw the FIA's controversial pop-off valves used for the first time on the turbocharged cars. The valves limited turbo boost pressure to 4.0 Bar where previously boost was only limited to what the engineers felt the engines could take. The valves were far from popular with the teams and drivers though with some drivers complaining throughout the weekend that they were cutting in too early and not allowing enough boost. Arrows driver Derek Warwick told that at times his valve was opening at just 2.6 Bar (a loss of approximately ) while Benetton's Thierry Boutsen told that the two valves on his Ford V6 were both opening at different levels and both well below the 4 Bar limit. McLaren got around the pop-off valve problem by limiting turbo boost on their TAG-Porsche engines to just 3.6 Bar of pressure throughout the weekend, thus never allowing the valves to come into play. One un-named team mechanic was reported to have said that the valves were the only crude piece of engineering on a modern grand prix car The Ligier team was absent from Rio, missing their first race since the French boycott of the 1985 South African Grand Prix. The team had been set to use a new 4-cylinder, turbocharged Alfa Romeo engine for the season and were to use the Alfa Romeo 890T V8 turbo for the first race while debuting the new Alfa 415T in the second round in San Marino. However, during pre-season testing lead driver René Arnoux compared the new 415T to used food. This gave Alfa's parent company Fiat the excuse they wanted to pull out of its association with the team leaving Ligier without an engine for the season, though Ligier were able to secure a supply of Megatron turbo's from the Arrows team sponsors USF&G and would use them from San Marino until the end of the season. 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「1987 Brazilian Grand Prix」の詳細全文を読む スポンサード リンク
