ベルトラン・ガショー
In the Friday morning pre-qualifying session, an Onyx topped the time sheets for the fifth Grand Prix in succession. Stefan Johansson was again comfortably fastest by over a second, and his team-mate Bertrand Gachot also pre-qualified in third. The other two pre-qualifiers were the Larrousse-Lola cars of Michele Alboreto in second, and Philippe Alliot in fourth.
