McLaren won 6 races out of 16, and the world title went to Ayrton Senna.
In 1990 Alain Prost moved to Ferrari and won five races, while Ayrton Senna won six for McLaren and started from pole 10 times.
It was settled at Suzuka, just as a year earlier — but the other way round: Senna, starting from pole, collided with Prost at the very first corner, both retired, and Senna became champion for the second time. Nelson Piquet won both of the season’s last two races, in Japan and Australia, for Benetton.
