Clean Snowmobile


About Clean Snowmobile Challenge

Each year the Clean Snowmobile team designs a snowmobile that is acceptable for use in environmentally sensitive areas such as our National Parks. Clean Snowmobile Challenge (CSC) is primarily an “engine” competition, however, the underlying theme has remained consistent to engineer an environmentally clean, quiet trail sled. The team participates in a March competition in Michigan’s Upper Peninsula. 

Competition Details

One 6-day competition with up to 25 teams is conducted in Houghton, MI.

There are three classes of snowmobiles: Internal Combustion (IC), Zero Emissions (ZE), and Diesel Utility (DU). The Iowa State Clean Snowmobile team participates in the IC class, which is scored on 12 different categories.

The first day is centered around technical inspections and introductions. The next day is the grand opening event with an electric sled range test. After that teams present their designs, complete emissions tests, and draw bar pulls. Thursday is the handling event and Friday continues emissions tests. Saturday, the public viewing day, is the finale with the Polaris Acceleration event, objective handling event, and Awards.

More information about the event can be found on the SAE Clean Snowmobile Challenge website.
