Sunday 13th September 1992
Ayrton Senna won the Italian Grand Prix on the day that Nigel Mansell announced that he would retire from F1 at the end of the season, blaming Williams for not doing enough to keep him. Having qualified on pole, Mansell rocketed off into the distance, building a 12 second lead over team-mate Riccardo Patrese before bizarrely slowing and allowing him past before sitting on his gearbox. The strange spectacle ended with a hydraulics failure for the Williams. Patrese led Senna before a hydraulics problem also forced his retirement, Martin Brundle and Michael Schumacher following the Brazilian home.
