Senna's first race for McLaren got off to a bad start when the cars gear selector broke on the grid, causing a restart. The Brazilian was eventually disqualified for switching to the spare car after the green flag had been waved following the warm-up lap. At the time he had risen up to second place after starting from the pits. Making it look easy and confirming his mastery of the circuit, Prost won his fifth Brazilian Grand Prix in seven years, easing off over the last few laps to ensure he finished with enough fuel not to be underweight to finish 10 seconds in front of Berger, with World Champion Nelson Piquet finishing third in his first race for Lotus-Honda. With Derek Warwick (Arrows-Megatron), Alboreto (Ferrari) and Satoru Nakajima (Lotus-Honda) finishing 4th, 5th and 6th respectively the points were a clean sweep for the turbo powered cars, though Mansell and the Benettons of Boutsen and Nannini did run in the points for long periods of the race.
