In 2010, Ginetta decided to cancel plans to produce a road-going version of the bigger Ginetta G50, and instead built a road-going variant of the G40, named the G40R. The race car's 1.8-litre Zetec engine was replaced with a modified 2.0-litre Mazda MZR engine, generating a power output of 175 horsepower at 7,000rpm and the 6-speed manual gearbox shared with the Mazda MX5; however, the road car also includes the full race-spec rollcage.
