In {{F1|1985}}, [[Patrick Head|Head]] designed the [[Williams FW10|FW10]], the team's first chassis to employ the [[carbon fibre-reinforced polymer|carbon-fibre composite]] technology pioneered by McLaren. [[Nigel Mansell]] replaced Laffite to partner with Rosberg. [[Frank Dernie|Dernie]] produced another competitive aerodynamic package. The team scored four wins with Rosberg winning the [[1985 Detroit Grand Prix|Detroit]] and [[1985 Australian Grand Prix|Australian Grands Prix]], and Mansell won the {{F1 GP|1985|European}} and the {{F1 GP|1985|South African}}. Williams finished in third in the Constructors' Championship, scoring 71 points.

During qualifying for the {{F1 GP|1985|British}}, Rosberg completed a lap of the circuit in 1:05.591. The lap's average speed was {{convert|160.938|mph|km/h|abbr=on}}. This was the fastest recorded lap in Formula One history to that point.

From 1985 until 1993, Williams ran their famous yellow, blue and white [[Canon Inc.|Canon]] livery.
