#1 Senna's first title - 1988 Japanese Grand Prix
Before the two championship-deciding collisions in 1989 and 1990, Senna was involved in a title-deciding race against his teammate Alain Prost at the 1988 Japanese Grand Prix.
The McLarens locked the front row with Ayrton Senna on pole position; however, the Brazillian stalled on the grid at the start of the race. Senna eventually managed to jump-start his car, but this move dropped him to the fourteenth place.
Ayrton Senna started making progress to catch up the lead pack when the racetrack was showered with inconsistent rain. Prost's malfunctioning gearbox helped his cause. Finally, on lap 27, the Brazilian managed to pass the Frenchman to take the race lead.
Senna held his ground from there on and took the race win by a gap of 13 seconds, which was his eighth win of the season. The victory decided the championship in the Brazilian's favour, much to the disappointment of Alain Prost.
