LEC was a UK motor racing team and Formula One constructor based at Bognor Regis, West Sussex. They participated in ten Grands Prix using a March in 1973 and their own car, the LEC CRP1, in 1977. In 1973 David Purley hired a March 731 and with backing from his family's refrigeration company LEC Refrigeration, made a largely unsuccessful attempt at Formula One. Purley and the team made their debut in Monaco where the fuel tank broke. Purley did not make the restart at the British GP after he spun off. It was at the 1973 Dutch Grand Prix, however, where Purley carried out arguably his most memorable actions. Upon witnessing a crash which left fellow British driver Roger Williamson trapped in his overturned and burning car, Purley abandoned his own race and attempted to save Williamson, who was participating in only his second Formula One race.

LEC racing returned to Formula One in 1977 with their own LEC chassis designed by Mike Pilbeam and run by Mike Earle. It was this car in which Purley suffered serious injuries in an accident during pre-qualifying for that year's British Grand Prix. He survived an estimated 179.8 g when he decelerated from 173 km/h (108 mph) to 0 in a distance of 66 cm (26 inches) after his throttle got stuck wide open and he hit a wall. For many years, this was thought to be the highest g-force ever survived by a human being. He suffered multiple fractures to his legs, pelvis and ribs.
