Mansell began an epic charge, breaking the lap record eight times to the delight of the over 100,000 strong British crowd. By lap 62 Mansell was right on Piquet's tail, and on lap 63 the Englishman overtook his teammate. Shortly after crossing the finish line, Mansell's car slowed down and was engulfed by the crowd. Initially it was thought that he had run out of fuel, but he had actually blown up the engine, out of the stress of running the last 6 laps on "Q" mode (which gives the engine +100hp), and risking running out of fuel at any moment (his fuel display was reading "minus 2.5 laps"). In fact that incident was the last straw for the patience of the Honda management, since it had – again – threatened their easily attainable 1-2 result. Honda would switch their supply of engines from Williams to McLaren for 1988, while Piquet would sign for Lotus – also running Hondas – in the following weeks. Senna finished third, one lap down, with a further lap back to teammate Satoru Nakajima in fourth. Derek Warwick was fifth in the Arrows-Megatron, with Fabi completing the top six.
