By the late 1970s British Leyland no longer ran a ‘works’ rallying or racing team. Some kind of involvement, however, was maintained by many of the companies which formed the Group, often in the form of sponsorship. One example of this was the sponsorship by Leyland Vehicles of the Williams Formula One Grand Prix racing team, which gained the 1980 World Championship with driver Alan Jones.

Unipart, at that time a British Leyland (BL) parts subsidiary, also took an interest in motor sport and sponsored this March Formula 3 car which used a highly developed version of BL’s own 2.0 litre, 16 valve engine from the Triumph Dolomite Sprint.

The Unipart team competed in the British Formula 3 series from 1976 until 1979, each year using the March chassis. Unipart F3 cars were driven by, amongst others, Tiff Needell, Tony Dron, Brett Riley and Nigel Mansell, who would go on to be the Formula One World Champion.
