The Rover-BRM was a prototype gas turbine-powered racing car, jointly developed in the early 1960s by the British companies Rover and British Racing Motors (BRM). Rover had already been working with gas turbines for road vehicles since World War II. A series of potential road cars had also been produced, from the early prototype Jet 1 through the more developed examples T2, T3 & T4. T4 had even displayed demonstration laps around the Le Mans circuit, before the 1962 race. Seeing an opportunity for even more prestige, Rover decided to enter a gas turbine car into the race. A prize was to be awarded for the first gas turbine car to complete 3,600 km over the 24 hours, an average speed of 93 mph.
