apprehensive about being behind the Ligier thanks to the unpredictable de Cesaris' reputation for crashing. Mansell dropped out on lap 18 with a clutch failure, before team-mate Rosberg suffered a broken exhaust four laps later. Senna continued to lead, with Prost now second and Lauda up to third ahead of de Cesaris, Piquet and Alboreto. Prost and Lauda's McLaren-TAG/Porsche MP4/2B's performance through high-speed corners was far superior to that of any other car competing that year – something that was a feature of all of the original Silverstone's 8 corners (10 if the 3-turn sequence of the Woodcote chicane is counted). Alboreto passed Piquet for fifth, before moving up to fourth on lap 42 when de Cesaris's clutch failed. By then, Senna and Prost were running nose-to-tail. The Frenchman finally passed the Brazilian on lap 58, Lauda's electrics failing on the same lap. Then Senna's fuel injection failed, promoting Alboreto to second, while Jacques Laffite in the second Ligier moved up to third ahead of Piquet. The chequered flag was erroneously shown at the end of lap 65, one lap early, with Prost having lapped the entire field. Halfway around what was meant to have been the final lap, Laffite ran out of fuel, which annoyed Piquet – he would have thus taken the final podium place had the error not been made. The final points were taken by Derek Warwick in the second Renault and Marc Surer in the second Brabham. In the Drivers' Championship, Prost moved to within two points of Alboreto, while in the Constructors' Championship McLaren moved up to second, 18 points behind Ferrari.
