How many Formula One World Championships did Ayrton Senna win? Ayrton Senna won three Formula One World Championships.
The Brazilian driver claimed his titles in 1988, 1990, and 1991. His first championship came with McLaren-Honda, when he won eight races and edged teammate Alain Prost under the season’s points-counting rules. Senna successfully defended the title in 1990 and 1991, establishing himself as one of Formula One’s leading stars.
A common mix-up comes from confusing Senna’s three titles with Prost’s four or Juan Manuel Fangio’s five. Senna remained a championship contender in 1992 and 1993 but did not win either season. He later captured a third-place finish in the 1993 championship before his death during the 1994 San Marino Grand Prix.
