- Brabham_BT54 abstract "The Brabham BT54 was a Formula One racing car designed by Gordon Murray for the Brabham team for the 1985 Formula One season. The car was powered by the BMW M12 4cyl turbo engine (generally agreed to be the most powerful engine in Formula One at the time) and used Pirelli tyres. Like most of its rivals, Brabham had used Michelin tyres in 1984. However, when the French company pulled out of Grand Prix racing at the end of that season, team owner Bernie Ecclestone took a gamble and instead of signing with Goodyear for their proven rubber, signed with the Italian company instead.Like its immediate predecessors, the BT54 had most of its weight towards the rear of the car to help improve traction. With FISAs ban on the 'winglets' on the rear wings that had been pioneered by Ferrari in 1983, Murray chose instead to put the small wings on the outside rear edges of the cars sidepods (Lotus designer Gérard Ducarouge had done the same with their 97T).The car proved to be competitive, but somewhat unsuccessful even in the hands of two time world champion Nelson Piquet. The reason for this turned out to be the Pirelli tyres which proved to be nowhere near as good as the Goodyear tyres used by rivals McLaren, Lotus, Ferrari and Williams. Part of the BT54s problem was that unlike the other teams who had tested their cars in Europe, Piquet had spent the summer testing the car and the Pirelli tyres at the Kyalami circuit in South Africa. The testing was completed in hot conditions which suited the Pirellis as it allowed them to quickly get up to working temperature which masked their major flaw. Unfortunately, once the European races started the problem surfaced of the front tyres taking a long time to reach working temperature (much longer than the Goodyears) which caused severe understeer, a situation wasn't helped by the unseasonably cool European summer or the lack of weight at the front of the car.The only track and conditions on the 1985 calendar that suited the tyres was the Paul Ricard Circuit used for the French Grand Prix and, combined with the BMW engine that was very effective on the Ricard circuit's long Mistral straight Piquet used these factors to his full advantage. He qualified 5th and won his only Grand Prix of 1985. The team's second driver Marc Surer recorded the season's fastest speed trap time during qualifying at Paul Ricard when the 900 bhp (671 kW; 912 PS), turbocharged BMW engine pushed the BT54 to 338 km/h (210 mph) on the 1.8 km long Mistral Straight.The car's good aerodynamics, and the powerful BMW engine, saw that the BT54 did well on high-speed circuits, and Piquet often qualified up on the grid on circuits like Paul Ricard, Silverstone, the Österreichring, Zandvoort, Spa-Francorchamps and Kyalami. Other than the Dutch Grand Prix at Zandvoort, where Piquet got his only pole position for the season (compared to his 9 poles in 1984), the BT54 was generally off the pace of the front runners leaving Piquet little chance of regaining the World Drivers' Championship (Piquet's pole in the Netherlands came to nothing when he stalled at the start and by the time he was push started, he was already two-thirds of a lap behind).At the European Grand Prix at Brands Hatch, Piquet qualified a strong 2nd, but on lap 7 drove into Keke Rosberg who had spun his Williams while challenging Ayrton Senna's Lotus for the lead at Surtees (with nowhere to go and no time to react, Piquet hit the Williams, taking off the BT54s nose cone and badly damaging the front left wheel and suspension). Piquet's teammate Marc Surer managed to get his BT54 up to 2nd before retiring with a fiery engine failure 13 laps from home.Piquet, François Hesnault and Marc Surer, who replaced Hesnault from the Canadian Grand Prix for the rest of the season, could only score 26 points to finish 5th in the Constructors' Championship.The BT54 was replaced for the 1986 season by the Brabham BT55, although the team did use the BT54 for the 1986 British Grand Prix at Brands Hatch after the lack of results from the radical lowline BT55.After seven seasons, 2 World Drivers' Championships and 12 wins, the BT54 was the last car Nelson Piquet drove for the Brabham team. With Brabhams declining competitiveness becoming apparent (giving Piquet just three wins in the two years since his 1983 championship, during which time McLaren drivers Niki Lauda and Alain Prost had won 18 races between them and each respective World Championship), the Brazilian signed to drive for Williams-Honda in 1986. The move to Williams proved to be fruitful for Nelson, winning seven races in two seasons as well as the 1987 World Championship.".
