of the session he was bumped down to sixth place. Langes never got back in the car, and was ultimately thirteen seconds adrift of Moreno's time in eighth place. Bertrand Gachot struggled badly again in the Coloni, faster than Langes but still ten seconds off Bernard's pace in seventh. The Coloni's Subaru 1235 engine, built by Motori Moderni, was proving to be overweight, underpowered and fragile. Bottom of the time sheets was Gary Brabham in the Life, failing to post a time at all. The car's engine broke a connecting rod after a quarter of a lap, leaving Brabham and his manager to question the Australian's future at the team.

On lap eight Boutsen passed Berger for second place, and Prost took the V12 Ferrari past the McLaren driver on lap 17. Mansell pitted on lap 27 for new tyres and also to inspect a broken rollbar, rejoining in 9th place. Boutsen's pit stop on lap 30 went disastrously wrong. With failing brakes, and a tricky bump in the pitlane, the Williams was unable to stop and crashed into some of his mechanics and the wheel and tyre equipment stacked outside the garage. This required a new nosecone and when he rejoined, he was down in 11th position.
