with Senna just under a second faster than Prost, who was himself almost eight-tenths faster than the Ferrari 640 of Nigel Mansell. During the Friday session Senna ran over a stone which put a sizeable hole in his car's undertray and the resulting damage would require a complete change of car, the problem being that the team only had three of the new transverse gearbox cars in Germany. As a precaution, team manager Jo Ramírez instructed the team's secondary (test) crew, who were on their way to Imola for a week of testing with the new car, to stop in Dijon (eastern France) in case the race team needed a replacement chassis. When Senna's car was deemed too badly damaged, the test crew made their way to Hockenheim and McLaren were back to having three full cars ready for use by Saturday's morning practice.

Alboreto had qualified 26th and last, only 0.016 ahead of the Minardi of Luis Pérez-Sala. Berger's lead was to last about a quarter of a lap as a result of the greater power of the Honda V10 engines. Senna had Berger before the first chicane, and Prost outbraked him at the Ostkurve. At the start of the second lap, it was Senna leading from Prost, Berger, Mansell, Thierry Boutsen (Williams-Renault), Alessandro Nannini (Benetton-Ford), Emanuele Pirro (Benetton-Ford), Riccardo Patrese (Williams-Renault), and Nelson Piquet (Lotus-Judd). The McLarens of Senna and Prost and the Ferraris of Mansell and Berger started to pull away from the field, with the Benettons of Pirro and Nannini, and the Williams of Patrese just
