In , the car won first time out in Brazil with Piquet, before Mansell laid down a title challenge with four wins. Williams were shaken by the near fatal road crash of Frank Williams which demoralised the team. Williams survived the crash but became a quadriplegic as a result, with the 1986 British Grand Prix the first time during the season he would appear in the Williams pits as he went through his rehabilitation. Patrick Head stepped up and managed the team until Williams returned late in the season. This may have caused the in-fighting between the two team mates, and the lost points helped Alain Prost take his second world championship. That and Mansell's spectacular blow out in the final race in Australia where all he had to do was finish third to win the title. The points built up between Piquet and Mansell were enough for Williams to take the constructors' championship, however.
