The Williams FW11 Formula One car, was designed by Patrick Head and Frank Dernie as a serious challenger to McLaren.

The car took over from where the FW10 left off at the end of 1985, when the car, powered by the Honda RA165E, won the last three races of the season. The FW11's most notable feature was the Honda 1.5 Litre V6 turbo engine, the most powerful in F1 at that time, producing 800 bhp at 12,000rpm and well over 1,000 bhp in qualifying. Added to the engine's power were the aerodynamics, which were ahead of the McLaren and the Lotus 97T.

Together with its excellent driving pairing of Nelson Piquet and Nigel Mansell, the RA166E of the FW11 made it a force to be reckoned with. The car was an instantly recognisable product of the new turbo era of F1.
