The 1986 Australian Grand Prix took place on October 26th at the Adelaide Street Circuit in Adelaide , South Australia and was the final race of the 1986 Formula 1 World Championship .

In addition to the two Williams drivers Nigel Mansell , who had been the leader in the world championship to date, and Nelson Piquet , McLaren driver Alain Prost also had a chance of winning the world championship. The decision was made by Mansell's puncture, which resulted in Prost winning races and world championships.

Reports

background

After the Mexican Grand Prix , Nigel Mansell led the drivers' standings by six points over Alain Prost and seven points over Nelson Piquet . Third place would have been enough for Mansell to win the title, while Prost and Piquet had to win. Williams-Honda led in the constructors' championship with 48 points ahead of McLaren-TAG and with 78 points on Lotus-Renault . Williams-Honda was already established as constructors' world champion and positions two and three were final.

The Australian Grand Prix was the last race for Keke Rosberg ( 1982 world champion ) and Alan Jones ( 1980 world champion ) on his comeback. Allen Berg , Johnny Dumfries , Huub Rothengatter and Patrick Tambay also contested their last Formula 1 race in Adelaide.

After the 1986 season, the Haas and Renault team withdrew as engine suppliers.

With Rosberg (once), the only former winner in the Formula 1 World Championship competed at this Grand Prix. With Prost and Jones (one each), two other former winners competed in this Grand Prix, which was not part of the Formula 1 World Championship until 1984.

training

In Friday's free practice session, Mansell set the fastest lap time ahead of his team-mate Piquet. Ligier-Renault driver René Arnoux was in third place . In Saturday's free practice session, Prost took the lead. Second and third place went to Gerhard Berger and Arnoux.

Qualifying

In the first qualifying on Friday, when it rained at times, Mansell set the fastest lap ahead of Prost and Piquet. In the second qualifying session on Saturday, the Brit was able to improve his lap time and was again the fastest driver. Piquet was second ahead of Ayrton Senna .

Mansell secured the pole position 0.311 seconds ahead of his team rival Piquet. Senna finished third, ahead of Prost, who was more than a second behind the fastest lap.

Warm up

In the warm-up on Sunday morning, Senna was the fastest driver ahead of Prost and Mansell.

run

Mansell got off to a bad start and lost the lead to Senna before the Wakefield corner, shortly afterwards he was overtaken by Piquet and Rosberg. Piquet took the lead on the first lap, while Senna lost place by place and played no role in the outcome of the race until his retirement on lap 43. On lap seven, Rosberg overtook Piquet, who thus led the field in his last Grand Prix. Piquet spun on lap 23 and lost a few positions, but his car was undamaged. Prost had to pit a little later because of a flat tire. The Goodyear technicians examined its tires and wrongly believed that their drivers would not need a scheduled pit stop to change tires.

The decision of the Grand Prix and the World Championship was made in the last racing quarter. Rosberg was clearly ahead of Piquet, Mansell and Prost, who moved up to second place again. On lap 63, Rosberg had to retire on the Brabham Straight due to a tire damage - at the same point where Rosberg's predecessor at McLaren, Niki Lauda , also retired in the last Formula 1 race of his career and was in the lead due to a brake defect the year before . Only one lap later, Mansell, who had been passed by Prost shortly before but was still safely in third place, suffered a tire damage at top speed while lapping Philippe Alliot's Ligier. Thanks to his vehicle control, he was able to steer his Williams into the run-off zone. Mansell's team-mate Piquet was then immediately called into the pits to change tires, which gave Prost the lead and finally won the race and the 1986 World Championship with a 4.2 second lead over Piquet. Mansell was runner-up in front of Piquet.

Third in the Australian Grand Prix went to Ferrari driver Stefan Johansson , who benefited from fuel problems with Tyrrell drivers Martin Brundle and Philippe Streiff , who were classified fourth and fifth. Dumfries scored the last point in sixth.
