The 231-hp Audi S1, an all-wheel-drive hot-hatch, is one of those vehicles that Audi doesn’t think Americans would buy. Perhaps justifiably so, as it is based on the small VW Polo chassis and costs as much as the Golf R. And the Golf R seems better in every measurable way, lacking only the cachet of the four-ring badge, if such thing even exists. 
Some loony hoon, somewhere, decided that it would be a good idea to remove the wheels off his S1 and replace them with tracks. Then he went to the beach with it. The result is something that looks incredibly fun.
