The 1991 Brazilian Grand Prix was a Formula One motor race held at Interlagos on 24 March 1991. It was the second race of the 1991 Formula One World Championship.
The 71-lap race was won from pole position by local driver Ayrton Senna, driving a McLaren-Honda. It was the first time Senna had won his home Grand Prix, in his eighth season of F1. Italian Riccardo Patrese finished second in a Williams-Renault, with Senna's Austrian teammate Gerhard Berger third.
Pre-qualifying report
In the Friday morning pre-qualifying session, a Dallara was again the fastest car, but this time it was JJ Lehto who topped the time sheets. He was six tenths of a second ahead of the Jordan of Andrea de Cesaris, who was a fraction faster than his team-mate Bertrand Gachot in third. The fourth pre-qualifier was the other Scuderia Italia Dallara, driven by Emanuele Pirro.
The two Modena Lambos missed out in fifth and sixth, with Eric van de Poele over a second slower than Pirro, with Nicola Larini another second further back. Seventh was Pedro Chaves in the Coloni, followed by Olivier Grouillard in the Fondmetal. Grouillard had initially used an interim chassis, with an eye to the team's new car which was still being completed, and was running well until the suspension broke. He was forced to revert to an older chassis, and was unable to match the times of his opponents.[1]
