The FW11 designed by Frank Dernie was the Williams car for the 1986 season which brought the Constructor’s title to the team and almost won the Drivers’ Championship. The FW11 inherited the overall design from FW10 which won last three races in 1985. FW11 features were moulded carbon composite monocoque, exceptional aerodynamics, and Honda 1.5 Litre V6 turbo engine, one of the most powerful in F1 at the time producing 800 bhp at 12,000 rpm in race and well over 1,200 bhp at 12,000 rpm in qualifying. Williams signed twice (at that time) World Champion Nelson Piquet to drive the FW11 alongside Nigel Mansell who retained his seat in the team. The duo of two talented and charismatic drivers was definitely the best on the grid, but their equality in performance and controversies in their relationships, as well as Frank Williams adherence, who was always more interested in the Constructors’ title than the Drivers’, probably costs the Champion tittle to one of them. Both Mansell and Piquet were able to win regularly and were the major contenders for the title along with Alain Prost from McLaren. The Championship was decided at the last race of the season. 1986 Australian Grand Prix in Adelaide saw the showdown of a three-way fight for the World Championship between Nigel Mansell, Alain Prost and Nelson Piquet. Mansell was on pole ahead of Piquet and Ayrton Senna (Lotus-Renault). Prost was fourth. The battle for the lead and for the Championship was very intense during the whole race. On lap 65 with 17 laps to go Mansell was on course for the title, Piquet was second and Prost was third. But on the Brabham Straights left rear tire on Nigel’s Williams exploded at 180 mph. Mansell managed to avoid hitting anything, but his championship hopes were over. Williams had no choice but to call Piquet to the pits and so Prost went into the lead. Piquet closed the gap from 15secs to four but Prost won the race and the World Championship after a breathtakingly exciting race.
