The Broadside project was the successor to the Lynx. Two models were envisaged, the first this GT version (a hatchback derived from the Lynx) and later a convertible (a lengthened TR7). David Bache was responsible for the exterior styling, improving the shortcomings of the Lynx by addressing the spare wheel location, petrol tank position and rear passenger headroom.

This example was constructed from a modified Lynx bodyshell and was the only prototype built. It was fitted with a Rover V8 engine. 

Work on the projects continued until 1980, but there was little engineering development as it was primarily a styling exercise. The decision was made to stop the project when sport car production was to be ceased within the company.
