As I remember, each vehicle ran it's own track and was timed. One that does come to mind Stolly V Haflinger. Stolly cheated and went across the lake in the middle. Haflinger ended up sideways in a bush. I think it was the late great Raymond Baxter as commentator whos said 'Oh dear I hope the driver is all right' and then stuck the microphone into the Hafflinger. The driver was OK, first time I heard swearing on Telly! :shocked: Thing was at the time there was a British Motor industry, Mokes , Ants, Gipsy, Land Rover, Alvis. Funny how a lot of these vehicles and concepts ended up being manufactured abroad. All of which is of course well off topic. But intresting how many componets and engine series were shared.
