Snowmobile Vehicle

An odd version of snowmobile is the Swedish Larven made by Lenko in Östersund from the 1960s until the end of the 1980s. It was a very small and basic design with just an engine in the rear and a track. The driver sat on it and steered using skiis on his feet.
Propulsion
Today, most snowmobiles are powered by either a 4 or 2-stroke internal combustion engine. However, a electrochemical battery-powered version has been made by McGill University. The engineers/students at McGill University are also working on a hybrid version of their snowmobile.
