Le Mans has long been a breeding ground for innovative, forward-thinking race cars. This year Nissan ventured into battle with its front-wheel-drive GT-R LM Nismo, eschewing decades of rear- and four-wheel-drive dominance, while BMW is considering a return in 2018 with a hydrogen-powered fuel cell racer.

The 2015 Coventry Motofest, however, played host to a much older car that had strived to push the envelope in a similar fashion, both at Le Mans and in the field of automotive engineering as a whole. The Rover-BRM, which took part in Le Mans 52 years ago, was a car that took the dramatic approach of ditching the conventional piston engine for a gas turbine.

It wasn't the first turbine-powered car, being preceded by Rover's own JET1 and myriad other prototypes, but it was the first turbine-powered Le Mans car. Its twin-shaft gas turbine produced 145bhp, which was sent to the rear wheels via a single-speed gearbox. It was claimed capable of dispatching the 0-60mph sprint in around 11 seconds, and had a top speed of 142mph.
