1991 British Grand Prix

The Friday morning pre-qualifying session resulted in a return to the Dallara / Jordan lockout seen three times earlier in the season. JJ Lehto was fastest in the Dallara, with Andrea de Cesaris' Jordan nearly seven tenths of a second slower in second position. Third was the Dallara of Emanuele Pirro, with Bertrand Gachot's Jordan a couple of tenths further back in fourth.

After pre-qualifying successfully at the last two Grands Prix, Olivier Grouillard missed out this time in fifth place for Fondmetal. The Modena Lambos were again sixth and seventh, with Nicola Larini again faster than Eric van de Poele. Nine tenths of a second further back in eighth was Pedro Chaves in the Coloni.[2]

In qualifying Nigel Mansell took pole in front of his home fans, with title rival Ayrton Senna second. Riccardo Patrese was third, followed by Gerhard Berger, Alain Prost, Jean Alesi, Roberto Moreno, Nelson Piquet, Maurício Gugelmin, and Stefano Modena.

Nigel Mansell gives Ayrton Senna a lift back to the paddock at Silverstone during his victory lap, after Senna had run out of fuel.

Senna made a rocket start to lead Mansell, while Patrese was the first casualty of the day, having been bumped off by Berger (Patrese retired after the first lap as a result). Senna's lead did not last for long as Mansell re-passed him going into Stowe corner. Roberto Moreno in the Benetton retired from sixth place with a gearbox failure on lap 22.

Mansell and Senna proceeded to rocket off into the distance while Berger, Prost, and Alesi squabbled over third place, with Alesi emerging ahead; he would later retire after colliding with Aguri Suzuki while trying to lap the Japanese driver's Lola.

Andrea de Cesaris had a huge accident on Lap 41 when his suspension failed at Abbey corner, his car bounced back across the track and narrowly missed Satoru Nakajima's Tyrrell; de Cesaris was unhurt.

At the front it was all Mansell as the Englishman recorded his second win in succession, while rival Senna ran out of fuel on the last lap and he was classified fourth. Berger ended up second, followed by Prost, Senna, Piquet, and Bertrand Gachot's Jordan. Mansell now trailed Senna by only 18 points and momentum was on his side.

In terms of having to pre-qualify, Brabham would have needed their top car at least in 7th position to demote the Leyton House team, but neither Brundle nor Blundell finished the race (Brundle retired with a broken throttle and Mark Blundell retired with engine failure later in the race on lap 53).
