The Westfield was born in 1982, from the idea of Christopher Kenneth Smith, a Jaguar D-Type and Lotus racing driver since the 1960s. Christopher decided to build for his personal use a car inspired by the Lotus XI. He named it Westfield in reference to the town of Westfield House where he embarked on his project in his own garage.

He covered a tubular chassis with a polyester shell, which was less expensive to manufacture than the aluminum bodywork of the original model. The Coventry Climax mechanics were replaced by a BMC engine used on the Austin Sprite and MG Midget, more affordable.

From his first outings on the track with his car, many enthusiasts approached him, wanting one for themselves. Chris Smith acceded to the requests, although it was not part of his initial intentions.

He then founded Westfield Sportscars in 1983. By 1984, he produced 87 units of his Westfield XI, delivering a total of 138 units until 1986. Since its beginnings, the manufacturer has offered its cars as kits or ready to drive.

In 2009, Westfield became the first British manufacturer to obtain European small series homologation for the SE Sport Turbo, renamed FW 300 in France and distributed by Patrice Dumas’ company (former Caterham importer), the original name of the project before it was renamed Sport Turbo by the parent company.
