Bad year for the team. One the way home from a testing session Frank Williams crashes his car and the accident leaves him paralysed.
Nelson Piquet joins the team replacing Keke Rosberg who moves to McLaren. Mansell and Piquet battle for top honours throughout the season. Going into the final race Mansell is in a strong position – until his wheel explodes on the main straight, handing the title to Alain Prost.
Williams however can take some consolation in winning the constructors championship by nearly 50 clear points.
