The 1986 Portuguese Grand Prix, otherwise known as the XV Grande Prémio de Portugal, was the fourteenth round of the 1986 FIA Formula One World Championship, staged at the Autódromo do Estoril on the 21 September 1986. The race would see Nigel Mansell claim victory to extend his Championship lead, as Williams-Honda secured the Constructors' Championship with two races to spare.
The race came amid another wave of announcements for 1987, most notably including the withdrawal of Pirelli as a tyre supplier, and Renault as an engine supplier. Ferrari, meanwhile, announced that they had signed Gerhard Berger to partner Michele Alboreto, leaving Stefan Johansson without a seat for the next campaign.
Qualifying had seen Ayrton Senna rediscover his early season form as he grabbed pole for Lotus-Renault, beating Mansell by over eight tenths of a second. Alain Prost was next ahead of Berger, with Teo Fabi ahead of the fourth man in the title fight Nelson Piquet.
The start of the race would see Mansell power past Senna off the grid, with the rest of the field thundering into the first corner behind them. Berger and Piquet, meanwhile, would get the jump on Prost, leaving the Frenchman to fend off Fabi during the opening tour.
Senna would send a series of attacks at Mansell early on,although the British racer was able to swat those efforts aside without issue. Indeed, the #5 Williams was soon able to escape the clutches of the Lotus, with Senna himself quickly left in a lonely second.
The race quickly developed into a rather tepid event, with the only major changes coming as Berger tried in vain to stay among the leaders. Mansell, meanwhile, was able to pit for fresh tyres and rejoin without losing the lead, while Senna would only briefly lose second to a recovering Prost when he stopped.
Onto the final lap, however, and Senna's title hopes were to evaporate, the Brazilian running out of fuel mid-lap and hence promoted Prost and Piquet. Indeed, as Mansell swept across the line to claim the win a frustrated Senna climbed out of his cockpit, eventually being classified in fourth place behind Prost and Piquet.
That late retirement removed Senna from the Championship, for he was now nineteen points behind the leading Mansell in fourth. The Brit himself had established a ten point lead after his fifth win of the season, with Piquet and Prost a point apart in second and third.
Nigel Mansell had effectively extended his Championship lead in Italy, although his teammate Nelson Piquet had emerged as his biggest threat to the title. Indeed, the Brazilian was now just five off his teammate arriving in Portugal, with Alain Prost in third, eight off the lead after his disqualification and retirement in Italy. Ayrton Senna, meanwhile, was on the verge of dropping out of the title fight, landing in Estoril thirteen off the lead.
In the Constructors' Championship it looked likely that Williams-Honda would take the crown in Portugal, with their Italian one-two leaving them with 117 points. McLaren-TAG Porsche could still mathematically beat the Anglo-Japanese effort, although they would have to claim first and second in all three remaining races without Williams-Honda scoring. Indeed, they were instead in a fight to consolidate second, with Lotus-Renault still a threat.

Victory moved Nigel Mansell ten points clear in the Championship with two races to go, meaning he could take the title with victory in Mexico. Indeed, either Nelson Piquet or Alain Prost would have to finish ahead of the Brit, and claim points, to keep the title fight alive, with Prost having to claim fourth or better regardless. Ayrton Senna, meanwhile, had fallen out of the title fight with two rounds to go, his late retirement ensuring he was nineteen off Mansell, with eighteen points to fight for.
In contrast the battle for the 1986 Constructors' Championship was over, for Williams-Honda had built an unassailable lead with two rounds to go. Indeed, their tally of 130 left them 49 points clear of McLaren-TAG Porsche, with the Anglo-German alliance effectively guaranteed second as consolidation. Lotus-Renault still had a mathematical chance of beating them to the runner-up spot, but would have to claim first and second in both of the remaining races to do so.
