The 1990 Belgian Grand Prix was a Formula One motor race held at Spa-Francorchamps on 26 August 1990. It was the eleventh race of the 1990 Formula One World Championship. The race was the 48th Belgian Grand Prix. It was the 36th to be held at Spa-Francorchamps and the seventh since the circuit was extensively redeveloped in 1979. The race was held over 44 laps of the seven kilometre circuit for a race distance of 301 kilometres. Brazilian driver Ayrton Senna claimed his fifth race victory for the season in his McLaren MP4/5B taking a four-second win over the Ferrari 641 driven the reigning world champion, Frenchman Alain Prost. It was Senna's fourth victory in the Belgian Grand Prix, and his third in succession. Senna's Austrian team mate Gerhard Berger finished third, while further back Maurício Gugelmin scored a point for the Leyton House team. Three attempts were made to start the race, the first two being red-flagged after collisions. Aguri Suzuki's Lola LC90 was eliminated after the first start, Paolo Barilla's Minardi M190 after the second. Off-track, Nigel Mansell was rumoured to be reconsidering his prior announcement to retire, and he was strongly linked with Williams. He had demanded undisputed number one status as a driver, and various assurances from engine supplier Renault, which Frank Williams had told him were impossible. The Onyx team pulled out of Formula One before the weekend of the race, for financial reasons, having competed at this level for a season and a half. Qualifying Pre-qualifying report With the withdrawal of the Onyx team, Ligier were relieved of the requirement to pre-qualify, and returned to the main qualifying pool. They had only been required to pre-qualify twice, which both cars did comfortably on both occasions. Therefore there was slightly less pressure on the other entrants in the pre-qualifying session. Olivier Grouillard was fastest in the Osella, the second time he had been top of the Friday morning time sheets, and the first time since round six in Mexico. Second fastest was Yannick Dalmas in the AGS, his fifth successful pre-qualification of the season from eleven attempts. Third fastest was Bertrand Gachot in the improving Coloni, and this was the first time in 1990 that he had pre-qualified. Fourth was Gabriele Tarquini in the other AGS, his fourth pre-qualification this season. Missing the cut in fifth and sixth positions were the EuroBruns of Roberto Moreno
