The 73-lap race was won by Alain Prost, driving a Ferrari, with teammate Nigel Mansell second and Alessandro Nannini third in a Benetton-Ford.

Bruno Giacomelli managed two laps in the L190 before it stopped out on the circuit, the switch to the Judd engine apparently not providing much improvement.

On the start Patrese collided with Jean Alesi, and sending the Frenchman into a heavy spin at turn 1 into the gravel trap and then retired as a result.

From there the Ferrari drivers eventually dominated the race with reigning world champion Alain Prost leading his teammate Nigel Mansell home by 22 seconds for a 1-2 finish.

Donnelly attributed his survival to safety improvements made after Riccardo Paletti's fatal accident at the 1982 Canadian Grand Prix.

The Larrousse-Lola of Aguri Suzuki claimed the final championship point of the race, continuing an encouraging season for the French team.

McLaren driver Ayrton Senna's lap 53 retirement with a failed radiator reduced his lead in the world championship over Prost to nine points with just the Japanese and Australian Grands Prix remaining in the season.
