The 1991 Portuguese Grand Prix was a Formula One race held at the Autódromo do Estoril on September 22, 1991. It was the thirteenth round of the 1991 Formula One season.

Report[link]

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[link]

• 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.

The Portuguese Grand Prix (Grande Prémio de Portugal) was a motorsports event held for several years, mostly in the 1950s and then in the 1980s and 90s. It was a Formula One race between 1958 and 1960 and between 1984 and 1996.

The first event was held on the Boavista street course in Porto on 17 June 1951 as a sports car race.^{[citation needed]} The Grand Prix was moved to Monsanto Park, Lisbon, in 1954 as a one-off. The first Formula One race was held in 14 August 1958 in Boavista, followed in 1959 by a Grand Prix at Monsanto, return to Boavista in 1960, after which it was ended.

The name was resurrected for a sports car sprint event in the Cascais street circuit in 1964. The following two years, it was run for Formula Three cars.

The seeds for the return of the Portuguese Grand Prix were planted with the inauguration of the Autódromo do Estoril in 1972. The Estoril Grand Prix was held as a European Formula Two Championship event during the 1970s. In 21 October 1984, Portugal returned to the F1 calendar, ending the season, where Alain Prost won the race but failed to win the Championship by half a point. In 1985, the Grand Prix was moved to April 21 and held under heavy rain, the ideal conditions for Ayrton Senna to win his first race. From 1986, the race was held in what would become its traditional date, in the penultimate week of September.

After the deaths of Senna and Roland Ratzenberger in Imola in 1994, the Estoril track was changed, with a new chicane built in place of the tank curve, as a security measure. Estoril was then considered an unsafe and outdated track, and the last Portuguese Grand Prix was in Estoril on 22 September 1996, with Jacques Villeneuve as the winner. Estoril was planned to be the final of race of 1997 season, but improvements to the circuit were not finished in time, so it was replaced with the European Grand Prix, which was held at Jerez in Spain.

On April 4, 2009 Max Mosley stated that based on the quality of the Autódromo Internacional do Algarve circuit, the Portuguese Grand Prix could be integrated into the Formula One championship, as long as a commercial agreement with the Formula One Management is achieved.^[1]
