This race would become one of the most notorious in F1 history, as the culmination of Alain Prost and Ayrton Senna's tumultuous two year rivalry as teammates at McLaren. The Japanese Grand Prix decided the 1989 Drivers' Championship in Prost's favour, after a collision on lap 47 at the final chicane between him and Senna put them both off the track. While Prost abandoned his stalled car, Senna restarted his, made a pit stop to change his front wing, and overhauled Alessandro Nannini to take victory. Following the race Senna was controversially disqualified for getting a push start from the marshals to rejoin the circuit, handing the title to Prost.
