Qualifying
Pre-qualifying report
As at the previous event in Germany, the Ligier drivers were first and second in the Friday morning pre-qualifying session. The positions were reversed, however, with Nicola Larini outpacing team-mate Philippe Alliot. The other two pre-qualifiers were the AGS cars, driven by Yannick Dalmas in third, and Gabriele Tarquini in fourth, the pair nearly two seconds slower than the Ligiers. It was the first time since the French Grand Prix that both AGS cars had pre-qualified, and only the second time this season.
Also for only the second time this season, Olivier Grouillard failed to pre-qualify in the Osella, as he was fifth fastest, less than two tenths of a second slower than Tarquini. There was a big improvement from Bertrand Gachot in the Coloni, now seeing the benefits of the Cosworth DFR engine in place of the Subaru, as he was sixth fastest, just 0.264 seconds behind Tarquini. The EuroBruns were seventh and eighth, Roberto Moreno a couple of seconds faster than Claudio Langes, and bottom of the time sheets as usual was Bruno Giacomelli in the Life, missing the cut by a very wide margin. On this occasion the L190 managed five laps before the engine expired. Piquet finished four seconds ahead of Patrese, with Derek Warwick in the Lotus and Éric Bernard in the Larrousse-Lola completing the top six.
Senna increased his lead over Prost in the Drivers' Championship to ten points, 54 to 44, with Berger on 29 and Boutsen on 27. McLaren also increased their lead in the Constructors' Championship, with 83 points to Ferrari's 57, followed by Williams on 42 and Benetton on 35.
