Winston Walter Frederick Percy (born 28 September 1943, near Tolpuddle, Dorset) is a British former motor racing driver from England.

On the back of these results he turned professional in 1974, driving Spike Andersons Samuri Datsun 240Z in the British Modified Sports Car Championship.

Despite remaining with Toyota during the 1983 BTCC season, Percy maintained his links to TWR with occasional drives in their V12 powered Jaguar XJS coupé which was proving the car to beat in Group A racing, and Walkinshaw managed to tempt him back full-time in 1984.

The following year after Jaguar shelved its touring car program to concentrate on racing Sportscars which saw TWR switch to works-backed Rover Vitesse V8s, again competing for the ETCC title.

He had been declared the champion until a month after the championship, when the FIA belatedly applied a rule that each driver's lowest scoring result would be dropped.

His Jaguar XJR-6 lasted for 10 of the 24 hours, partnered by Gianfranco Brancatelli and Hurley Haywood at the wheel, before a drive-shaft failure dropped the car out of the race from second place.

Percy entered Le Mans again the following year, but suffered a major crash when a tyre exploded at approximately 240 mph (386 km/h) on the long Mulsanne Straight, tearing off the rear bodywork and flipping the car into the air.

Percy contested the 1988 European Touring Car Championship driving a factory backed Nissan Skyline HR31 GTS-R with Allan Grice.

[4] Percy co-drove in the Australasian rounds of the 1987 World Touring Car Championship with Allan Grice in a Holden Commodore VL, and again at the 1988 Bathurst 1000.

As a team manager and lead driver, Percy would claim that his hardest decision was to let Grice drive the final stint of the 1990 Bathurst 1000.

[citation needed] At the end of the 1991 Australian Touring Car season after two years in charge of the Holden Racing Team, Percy and his wife returned to England.

He sued the West Dorset General Hospital National Health Service Trust and received an out of court settlement of £1.55 million in April 2008.
