grid due to Mansell being unable to start. This also meant Roberto Moreno was permitted to race the AGS despite having the 27th fastest qualifying time. Qualifying classification Race At the start Berger immediately imposed his authority by building a cushion. Prost, in his McLaren, perhaps the only driver capable of challenging Berger for the victory, suffered a puncture on the first lap and, therefore, was out of contention. Prost, however, drove a superb race to climb up through the field finishing just outside the points with the consolation of having the fastest lap. Boutsen's Benetton ran second early on but could not live with the pace set by Berger, ultimately fading to fifth. Piquet spent much of the race behind Senna's Lotus but was unable to find a way past his countryman. The new world champion eventually retired in the pits with oil pouring from the rear of his Williams. At one stage Stefan Johansson in the McLaren closed on Berger, but the Austrian driver responded and eventually romped to a seemingly effortless victory, the first Ferrari's victory since the 1985 German Grand Prix. Ayrton Senna dramatically passed Johansson on the last lap to take second place. Michele Alboreto, in the second Ferrari, got away very slowly at the green lights leaving him towards the rear of the field. However, the Italian drove an aggressive race to climb his way back up the order to finish an excellent fourth despite suffering from a dragging undertray causing a huge amount of sparks. Boutsen and Nakajima rounded out the points. Johansson's third place was the 54th and last podium finish for the Porsche-designed TAG turbo V6 engine which had been first used in Formula One by McLaren at the 1983 Dutch Grand Prix.
