The Clean Snowmobile Challenge is the newest collegiate design competition of the Society of Automotive Engineers. Engineering students from participating schools reengineer a stock snowmobile to reduce emissions and noise and increase fuel efficiency—all while preserving the riding excitement demanded by snowmobile enthusiasts.

The Challenge also includes a zero-emissions category, for battery-powered sleds, sponsored by the National Science Foundation. NSF uses electric snowmobiles while conducting atmospheric research in pristine arctic locations.

The Challenge is held annually at Michigan Technological University’s Keweenaw Research Center. For more information visit http://www.mtu.edu/snowmobile/ or http://www.superiorideas.org/projects/clean-snowmobile.
