Torres,
I believe Rover experimented with a number of gas turbine powered cars, both for road and competition use. One was driven by Graham Hill and Richie Ginther at Le Mans in 1963. Seem to recall seeing it at the Heritage Motor Centre situated at Gaydon - a former RAF 'V-Bomber base' - which just about gets this thread back to aviation !!
Then there was the Lotus gas turbine F1 car - I remember seeing it at Oulton Park in the late sixties - woops, drifting off again !! :o
