1990 Formula One World Championship
There were no changes until lap 11 when Piquet tried to pass Patrese and went through an escape road, allowing Nannini to get ahead. Three laps later Mansell went through the grass at Ostkurve without losing a place but damaging his car. It proved crucial as he retired two laps later, the damage being too much. Meanwhile, Nannini passed Patrese as the top three stopped for tyres, the Williamses and Benettons planning to go without a stop. Piquet retired with engine trouble.
