Portuguese Grand Prix 1986 - Race Schedule and Countdown

Nigel Mansell delivered a commanding victory at Estoril, controlling the Portuguese Grand Prix from pole position to reclaim the championship lead heading into the final two races. The British driver's fifth victory of the season demonstrated his ability to handle pressure, as he managed a comfortable race despite knowing the championship implications. Mansell's performance at Estoril appeared to seal his championship destiny, establishing a six-point advantage over Piquet with two races remaining.

Prost finished second for McLaren, keeping his mathematical championship hopes alive despite trailing by nine points. Piquet completed the podium in third, falling behind his teammate in the standings and seeing his title chances diminish. The Williams one-three finish showcased their continued dominance while highlighting how their internal battle had kept Prost in contention. With Mansell needing only to finish second in one of the final two races to guarantee the championship, his maiden title appeared inevitable. The victory at Estoril set up a tense finale, though few could have predicted the drama that would unfold at Adelaide.
