Soon Prost passed Boutsen for third as Mansell began to have troubles with his gearbox. Berger passed him to lead but then Mansell's car seemed to improve again. He repassed Berger but Prost was right behind them by now. Soon Prost sneaked by Berger and chased off after Mansell who had gearbox issues again. Prost got ahead of Mansell on lap 44 and pulled away.
