Sunday 27th September 1987
The Spanish Grand Prix was won by British driver Nigel Mansell driving a Williams FW11B. Mansell took victory by 22 seconds over Frenchman Alain Prost driving a McLaren MP4/3. Prost’s Swedish team mate Stefan Johansson finished third. It was Mansell’s fifth victory of the 1987 season. That win, along with Nelson Piquet’s fourth place, secured for the Williams F1 team their third constructors’ championship with three races still remaining in the season.
