简介：The 1991 FIA Formula One World Championship marked the 45th iteration of the prestigious FIA Formula One motor racing series. This season commenced on the 10th of March, 1991, and concluded on the 3rd of November, having witnessed a total of sixteen high-stakes races. The season was a historic one, with Brazilian ace Ayrton Senna securing his third and final Drivers' World Championship title, while the McLaren-Honda team triumphed in their fourth consecutive Constructors' Championship. Senna's performance was nothing short of spectacular, as he claimed victory in seven of the sixteen races. His closest contender for the crown was the seasoned Nigel Mansell, who, in his first season returning to Williams, managed to win five races. Senna's arch-nemesis, Alain Prost, experienced a disappointing campaign with Ferrari, failing to secure a single win and was subsequently dismissed from the team amidst a contentious dispute. The 1991 season also featured the remarkable debuts of future world champions Michael Schumacher and Mika Häkkinen, while heralding the retirement of the three-time world champion, Nelson Piquet.
