slower than Senna. Philippe Alliot snared a career best fifth place on the grid in his Larrousse, proving that both the Lola chassis and the Lamborghini V12 designed by Mauro Forghieri was starting to come good. It also enhanced Alliot's reputation as a demon qualifier. Williams-Renault entered two different model cars for their drivers Thierry Boutsen and Riccardo Patrese. Boutsen qualified 21st the new Williams FW13 that had debuted in Portugal, while Patrese reverted to the older model FW12C and ended up sixth on the grid ahead his former Brabham teammate Nelson Piquet in a surprisingly fast Lotus. René Arnoux (Ligier) and the Rial pair of Pierre-Henri Raphanel and Gregor Foitek all failed to qualify for the race.

World Championship leader Alain Prost finished third in his McLaren-Honda in what was his last race finish for the team with whom he won the and World Drivers' Championships. Rounding out the points were the 'find of the season' Jean Alesi in his Tyrrell in fourth, the older model Williams-Renault of Patrese in fifth in what would be the FW12C's final race, and giving the Lamborghini V12 its first ever points finish in Formula One was Alliot in what would be the best drive of his Grand Prix career.
