The turbo engines in the FW10's were driven by Briton Nigel Mansell and Finland's 1982 World Champion Keke Rosberg.

An upgraded version of the car, dubbed the FW10B, was introduced late in the season, which enabled the team to win the final three races of the year.

1984 had been difficult, as the FW09 struggled to cope with the enormous power and brutal torque curve, leading to handling problems which afflicted drivers Keke Rosberg and Jacques Laffite throughout the season.

[5] Mansell, having joined the team from Lotus at the beginning of the year, took his first F1 victory on home soil at Brands Hatch for the European Grand Prix, and immediately followed it up with his second, in South Africa.

The FW10 was the first Williams car to sport the distinctive yellow, blue and white livery that the team would use until the end of the 1993 season.
