Description The 1991 Portuguese Grand Prix was a Formula One motor race held at the Autódromo do Estoril on 22 September 1991. It was the thirteenth race of the 1991 Formula One World Championship.
The 71-lap race was won by Italian driver Riccardo Patrese, driving a Williams-Renault, after he started from pole position. Patrese's teammate and Drivers' Championship challenger, Briton Nigel Mansell, led until a pit stop went wrong, resulting in his disqualification from the race. Brazilian Ayrton Senna finished second in a McLaren-Honda, thus increasing his lead over Mansell in the championship to 24 points with three races remaining, with Frenchman Jean Alesi finishing third in a Ferrari.
Things were looking good for Williams until Mansell came in for his stop on lap 29 and disaster struck: a communications mix-up by the pit crew resulted in Mansell being sent off with the right rear wheel of his car not properly attached. The wheel rotated clean off and a frustrated Mansell was left stranded in the pit lane. In the heat of the moment, the crew scampered over to the car and fitted a fresh wheel outside of the pit box, a violation of the rules.
