The FW08 was a development of the Williams FW07 but featured a shorter wheelbase and much stiffer chassis to cope with the higher g-loading that the minimum ride height regulations introduced in 1981 demanded. While McLaren and others pioneered the use of carbon fibre chassis, Patrick Head stuck to aluminium honeycomb for the new car. The FW08 suited Keke Rosberg's aggressive driving style and he used it to good effect, winning the 1982 Swiss Grand Prix and scoring several other podium places to snatch the championship. Rosberg was on course to win in Belgium on the car's debut but tyre trouble caused him to drop back in the closing stages of the race. The FW08 was Frank Dernie's favourite car of all those he worked on during his time with the team.
