1984 Portuguese Grand Prix Wikipedia
The 1984 Portuguese Grand Prix was a Formula One motor race held at Estoril on October 21, 1984. It was the sixteenth and final round of the 1984 Formula One season. This was the first Formula One championship Portuguese Grand Prix since 1960, when it was held at the Boavista street circuit in Oporto.
Niki Lauda needed 2nd place to secure the title, and gained this when Nigel Mansell spun out with 18 laps to go. As a result, he took the title by just half a point from team-mate Alain Prost. The point-scoring drivers won a total of 13 world championships between them, and the three drivers on the podium were all (at least) triple World Champions from different eras - Niki Lauda, approaching the end of his long and distinguished F1 career, Alain Prost, enjoying the best years of his career, and Ayrton Senna, still at the dawn of his.
