Senna and Alain Prost, as they locked out the front row and were over 1.5 seconds faster than the Ferrari of Nigel Mansell. Riccardo Patrese showed his and Williams' revival with fourth on the grid followed by Gerhard Berger (Ferrari) with Thierry Boutsen rounding out the top six. At Tyrrell, Michele Alboreto failed to qualify for a race for the first time since the 1981 German Grand Prix, in the new Tyrrell 018. Only one 018 was available, and although team mate Jonathan Palmer managed to sneak onto the grid in 25th in the older model 017, he raced the 018. Qualifying classification Race Start and lap 4 accident (red flag) At the start Ayrton Senna got away well but behind him Alain Prost found himself just ahead of Nigel Mansell's Ferrari but the Englishman could not find his way around Prost's McLaren.

The race was red-flagged and Berger escaped with broken ribs and second-degree burns. Race restart and conclusion The race was restarted after half an hour and run a further 55 laps on aggregate timing.

Olivier Grouillard was disqualified on Lap 5 for his car being illegally worked on by his team during the one-hour delay. As the McLarens pulled away Mansell, Patrese, and Nannini were busy fighting over third place. It was
