In fifth place, failing to pre-qualify by a hundredth of a second, was Gabriele Tarquini in the AGS , with his team-mate Yannick Dalmas in sixth. It was the fourth double failure to pre-qualify for the French team. The other three entrants were a long way behind: Bertrand Gachot was seventh in the Coloni , nearly 16 seconds slower than Moreno.
