The competition for the drivers title was a cutthroat battle between Senna and Prost. The championship would be decided between the two in the following race, in Japan, and any extra points would be decisive.
Because of this, leaving Spain with a win was exactly what the two wanted.
The battle for pole position was an extreme and decisive one. Ayrton Senna was ahead by 67 thousandths of a second in the last minute of the qualifying session. He demanded 100% from both himself and his car to be able start in first position.
Prost still had a trick up his sleeve and had sufficient time to better set up his McLaren. In the race, Prost’s patience won him the race.
While Ayrton Senna’s audacity led him to a labored fourth. And the title was still completely open.
