Stefano Modena
Prost got a jump on Senna at the start, but hit a bump in the straight, causing his wheels to spin and the engine to be cut momentarily by the rev limiter allowing Senna to pull ahead, but by the end of the first lap his lead was only 0.45 seconds. Nannini ran third followed by Nigel Mansell, Alex Caffi, Stefano Modena, Martin Brundle, Gerhard Berger, Andrea de Cesaris and Michele Alboreto.
