The 1980 Finncat featured an unusual technological innovation: with no directional skis, it was guided and driven by the track, which consisted of two segments of pleated plastic. The segments stretched like an accordion and were joined longitudinally like a spinal column. Four guide wheels mounted on a directional pivot traveled along the centre of the track to provide steering. Two sprockets and the back gave the vehicle its forward power. The track would stretch to the right or left to turn the vehicle in the desired direction.
