Saturday Soichiro Honda, the founder of Honda, met Ayrton Senna in the McLaren pit. Qualifying Qualifying report After the withdrawal of the EuroBrun and Life teams, there was no need for a pre-qualifying session as only 30 cars remained in the event. The four drivers relieved of the necessity to pre-qualify, Yannick Dalmas, Gabriele Tarquini (both AGS), Olivier Grouillard (Osella) and Bertrand Gachot (Coloni) were ultimately the four drivers that failed to qualify for the race. Gachot crashed heavily in the Friday session. Roberto Moreno, who had left EuroBrun and joined Benetton, qualified easily in ninth position. Qualifying classification Race Race report Ayrton Senna qualified on pole, but was unhappy with the dirty side of the track it was situated on, arguing that pole should always be on the racing line. He and Gerhard Berger then went to the Japanese stewards, to request a change of position of pole to the cleaner left side of the track. The stewards initially agreed but an injunction by FISA president Jean Marie Balestre later that night rejected the decision and the original pole position remained on the dirtier right side of the track. In addition, the FIA had warned that crossing the yellow line of the pit exit on the right to better position oneself at the first corner would not be permitted, further infuriating Senna. At the start, Prost took the lead, but Senna attempted to take the inside line into the first corner. The two drivers made contact, sending both off the track and into instant retirement. The crash meant that Senna had clinched the Drivers' Championship for a second time, as with one race left in the season, Prost could not overtake his points tally. Benetton-Ford's dominance of the podium prevented Ferrari from scoring enough points to stop McLaren clinching its sixth constructors' title. The two discussed the event afterwards, with Senna claiming it was not how he wanted it but how it had to be. Prost was infuriated by this, and described the move as "disgusting" and Senna as "a man without value". He later said that he almost retired from the sport instantly after the incident. The pair went on to win one more championship each and eventually reconciled their differences in their final Grand Prix together. After the collision, the race proceeded with Gerhard Berger's McLaren MP4/5B leading and Nigel Mansell's Ferrari 641 second. Berger spun off
