Qualifying
Pre-qualifying report
In Friday morning pre-qualifying, the Larrousse-Lolas were again first and second, their fifth 1–2 of the season, with Éric Bernard nearly a second faster than team-mate Aguri Suzuki. As at the previous Grand Prix in France, third fastest was Gabriele Tarquini in the AGS. This time, the fourth pre-qualifying spot went to Olivier Grouillard in the sole Osella.
These four were comfortably faster than the other runners, the fastest of which was Roberto Moreno in a revised EuroBrun in fifth place. Sixth was Yannick Dalmas in the other AGS, his sixth failure to pre-qualify so far this season. Claudio Langes was seventh in the other, unrevised EuroBrun, with Bertrand Gachot a distant eighth in the Coloni after its engine destroyed itself yet again. Subaru ended their involvement with the Coloni team after this Grand Prix, with eight consecutive failures to pre-qualify, and the team were to source new engines for the next race in Germany. The Life team had no pit garage in which to prepare their car, and worked on the grass near the pits.
