Report

The only change to the driver line-up was that Johnny Herbert was back at Lotus and managed to qualify, something that Michael Bartels had failed to do in his three outings for the team. The sunny Estoril was a popular venue among the drivers and qualifying saw a bit of a role reversal with the top teams' second drivers beating the championship contenders with Riccardo Patrese on pole alongside Gerhard Berger, with Ayrton Senna and Nigel Mansell third and fourth respectively. The top ten was rounded out by Alain Prost, Jean Alesi, Maurício Gugelmin, Pierluigi Martini, Ivan Capelli, and Michael Schumacher, the Benetton team a little off their usual pace.

On Sunday Morning Prost's Ferrari had a rather dramatic blowup in the warmup, and the Frenchman had to start the race in the spare car. The start was very eventful with Patrese getting away well and with Mansell aggressively chopping across the front of Senna. Unimpressed, he tried to retake Mansell going into the first turn but Nigel held his line and then proceeded to sweep underneath Berger to grab second at the second corner. After lap 1 the order was Patrese, Mansell, Berger, Senna, and Alesi. Mansell seemed content to shadow Patrese until lap 18 when he slipstreamed past his teammate on the main straight and proceeded to pull away. Things were looking well for Williams until Mansell came in for his stop on lap 29 and things went horribly wrong. The right rear tyre men got confused and one mechanic raised his hand when the other had not gotten the wheel perfectly on. Mansell set off down the pitlane but his tyre did not want to comply, the tyre fell off and the frustrated Englishman was left stranded in the middle of the pit lane with three wheels. The team ran out and put a fourth wheel on the car, breaking many rules in the process.

Mansell emerged in 17th place and started a furious charge through the field. He was up to sixth when he was inevitably shown the black flag on lap 51; with this disqualification, his championship hopes hung by a thread. The whole accident left Patrese comfortably in the lead from Berger and Senna, and Senna went second when Berger's engine blew on lap 37, he was followed out of the race by Prost's Ferrari, which also decided it had enough. On lap 40 the order was Patrese, Senna, Alesi, Martini, and Capelli, with the latter three being involved in an exciting battle for third place; Alesi didn't make errors despite being under pressure from the Minardi, and so the order remained unchanged until the late stages when the fifth placed Capelli suffered a front wing problem and ended up in the barriers. Patrese cruised home to his second win of the season and fifth of his career. Senna was second and tightened the screw on his third drivers title. Alesi, Martini, Piquet, and Schumacher rounded out the top six. With three races to go Senna led Mansell by 24 points.

Notes

  • Nigel Mansell was disqualified for an illegal pit stop. He pitted from the lead but one of the mechanics on the right rear wheel signalled his job was done whilst his fellow mechanic was still fixing the wheel which fell off the car less than 10 yards later; Mansell's car was fixed up with the 4th wheel in the middle of the pit lane and lifted manually by mechanics, but this was against the rules and caused the disqualification. Mansell had rejoined 17th but was back in 6th when he was black flagged. Despite this, his fastest lap was kept.
  • Last race: Pedro Chaves
  • This was the last race for Olivier Grouillard with Fondmetal in 1991. He was sacked by that team following Monday after this race.
