Solutions - Clean Snowmobile Challenge
In 1999, in response to increasing concern about snowmobile noise and air pollution in environmentally sensitive areas, Teton County Wyoming Commissioner Bill Paddleford and environmental engineer Lori Fussell worked with the Society of Automotive Engineers (SAE) to form and organize a new intercollegiate design competition, the SAE Clean Snowmobile Challenge 2000 (CSC2000).
The goal of the competition was to develop a snowmobile with improved emissions and noise characteristics that did not sacrifice performance. Modifications were expected to be cost-effective and practical.
Events scheduled to take place during the CSC include emission testing, acceleration event, hill climb event, cold start testing, noise measurement, fuel economy/range event, and oral/written design.
The Clean Snowmobile Challenge 2000 (CSC2000) was held in Jackson Hole, Wyoming, and parts of Yellowstone and Grand Teton National Parks from March 20 through 31, 2000. Seven teams from participating universities competed against each other in the categories of emissions, fuel economy/range, noise, acceleration, handling, cold-start, hill climb, engineering design paper, oral presentation, and static display. Team were donated a 1997 used 500cc fan-cooled Polaris snowmobile to modify. Points were awarded to teams based on their performance in each of the events.
The CSC2015 is scheduled March 2-7 at the Keweenaw Research Center at Michigan Tech, Houghton, Michigan.
Kettering University, Flint, Michigan took top honors at the 2014 challenge. Kettering was second place finisher in 2012 and 2013. The full slate includes awards for zero emissions and overall performance.
The State University of New York at Buffalo (UAB) won the first place CSC2000 event with a snowmobile featuring a Polaris 500cc four-stroke engine and catalytic after-treatment. This first-place entry was successful at reducing noise and emissions while simultaneously improving fuel economy. From the first year of the Clean Snowmobile Challenge, it seemed clearly demonstrated that the noise and emission problems associated with traditional snowmobiles can be solved through advances in engine, noise control, and emission control technology.

- Clean Snowmobile Challenge 2001 emissions testing was conducted at Flagg Ranch, Wyoming, by Southwest Research Institute. Fuel type for sleds used in the analysis was an ethanol blend (E-10). The CO emissions analysis used a range of emissions rates for each engine speed from the top five placing snowmobiles since each machine was unique in design. The Clean Snowmobile Challenge 2001 results show the kinds of improvements in emissions that are possible from two and four-stroke engines used in snowmobiles.
- The Montana Department of Environmental Quality has completed a modeling analysis, comparing snowcoach emissions to those of various kinds of snowmobiles: Comparison of Carbon Monoxide Emissions from Snowcoaches, 1997 and 2001 Snowmobiles, and 2001 Clean Snowmobile Challenge New Technology Applications.
