ride the Ligier's rear right wheel and send both cars into a spin. Berger retired immediately with suspension damage, putting Prost back into the lead with Senna second. Behind the McLarens, Piquet was maintaining third ahead of the Williams pair of Patrese and Mansell. The Italian opened a small gap on his teammate and closed on Piquet, making several attempts to pass the Brazilian. However, he spun on lap 53, letting Mansell past. The Englishman was no more successful in trying to pass Piquet, and he retired on lap 66 when his brakes failed and he spun into the wall. By lap 59 Prost was putting in a succession of fast laps, extending his lead to over 30 seconds and lapping the whole field up to the fifth-placed Rial of Andrea de Cesaris. On lap 46, Pierluigi Martini spun his Minardi at the chicane and was almost collected by Stefan Johansson's Ligier. Maurício Gugelmin slowed his March to avoid the pair, only to be hit from behind by Satoru Nakajima's Lotus, putting both cars out. This crash also had an effect on Prost who was the first car upon the scene. The McLaren ran over some debris which broke off part of the front wing end plate, causing the car to understeer for the rest of the race, though Prost was able to play with his car's onboard settings to compensate and would set the fastest race lap later in the race. Alessandro Nannini spun his Benetton; Jonathan Palmer's Tyrrell suffered transmission problems; and Arrows drivers Derek Warwick and Eddie Cheever both suffered engine failures. Driveshaft trouble accounted for the EuroBruns of Modena and Oscar Larrauri, while Caffi succumbed to clutch failure in his Dallara. At the finish, only eleven cars were classified, of which just seven saw the chequered flag: de Cesaris, Johansson and Philippe Alliot's Larrousse-Lola all ran out of fuel in the closing laps, while Philippe Streiff's AGS suffered an electrical failure. Prost led home Senna in yet another McLaren 1–2, with Piquet third and Patrese fourth. De Cesaris' misfortune handed fifth place to Thierry Boutsen in the Benetton despite a spin and a stuttering engine, with Ivan Capelli taking the final point for sixth in his March despite a puncture. In the last race in which cars with turbocharged engines were allowed to compete until , all three podium positions were taken by cars powered by
