In 1982 Westfield Sportscars, responding to the popularity of the original Lotus XI, started production of a replica with a fiberglass body available as either a finished car or kit car. Initially called the Westfield Sports, the factory-finished cars were usually fitted with an uprated 1,275 cc (77.8 cu in) BMC A-Series engine, although some factory cars were fitted with Ford Kents.

The majority of Westfield XIs are sold as self-build kits without engines and designed to accept the 1275cc A-series from a donor MG Midget or Austin-Healey Sprite. Owners have fitted a variety of engines, including Coventry Climaxes, Lotus twin-cams and Alfa Romeo engines,[1] although engine fitment is limited by the small size of the engine bay. The kit is designed to utilise other components from a donor Sprite or Midget: the rear axle (modified by Westfield), gearbox, driveshaft, front upright/brake assembly, radiator, wheels/tyres, steering rack, wiring, and gauges.[2]

In 1983 and 1984, Road & Track featured two articles about the Westfield XI, telling the story of how the magazine's team built a kit car and subsequently took it for a 5,000-mile (8,000 km) cross-country trip from California to Wisconsin. This article raised awareness of the car in the United States and led to more sales.[3][4]

Production of the original Westfield XI ceased in 1986, although the company offered kits until about 1988. In 2004 Westfield restarted production, still using the A-series engine. Westfield continues to offer the XI kit in small production batches.[5]
