changing his right rear tire, the Frenchman dropped to seventh behind Modena's Tyrrell-Honda. On lap 48, Senna pitted without giving up the lead. Like Mansell, Patrese was having problems with the gearbox in his Williams, and when it selected neutral midway through Turn Seven, it caused him to spin out of second place. The car stopped on the outside of the track, perpendicular to the racing line. Piquet and Mika Häkkinen (making his F1 debut) barely managed to avoid him as they passed, but before Patrese could get out of the car, Moreno, in the second Benetton, went straight across the bow of the Williams, removing the nose of Patrese's car and the right front wheel of the Benetton. Neither driver was injured. Patrese and Moreno's cars remained on the course throughout the race, and Bertrand Gachot, driving the first race for the new Jordan team and challenging Satoru Nakajima, spun later after swerving to avoid them. With Patrese out, Senna led Piquet, who was having to hold off Alesi, by over a minute. Alesi squeezed up to second on lap 53, while four laps later Prost disposed of Modena. Then on lap 70, Prost went from fourth to second in one move at turn five. With Alesi and Piquet running second and third, Piquet's Benetton pulled alongside Alesi– who had set the race's fastest lap while Prost was in the pits– in Turn Four, but could not get by. Down the straight, however, Piquet passed Alesi for second place. Prost also went by his new teammate on the left, and then sliced back to the right, between Alesi and Piquet, beating Piquet to the apex of Turn Five and regaining second place. By now Senna led by 40 seconds. Gearbox troubles dropped Alesi to fifth before he retired less than 10 laps from the finish, leaving third place to Piquet who, like the two Tyrrells following, had never pitted for tires. Martini was pressing Satoru Nakajima for fifth, only to have his engine let go after 75 laps. A similar problem removed Gachot from eighth on the same lap, promoting Aguri Suzuki to sixth. The race ended a lap short of the planned 82 as the two-hour limit was reached, Senna taking the win having led every lap. After the race, Senna assessed his new car's performance: "I had small problems with the gearbox, and the car balance was
