Michigan Tech was sixth overall.

Michigan Tech’s team claimed the Caterpillar Corporation Award for Innovation. On their zero emissions sled, they moved the drive axle to the back, increasing efficiency. They were credited for “excellent critical thinking.”

Zero emissions captain Mike Rittenour discussed Michigan Tech’s first year in the category. “We learned a lot from our mistakes,” he said “We want to come back and do well. We need to start in September,” he said.

About the Program

The Society of Automotive Engineers (SAE) Clean Snowmobile Challenge is an intercollegiate design competition that is part of the SAE Collegiate Design Series.

The challenge requires student teams to design a snowmobile that achieves reduced emissions and noise characteristics while keeping performance equal to or better than the performance of stock snowmobiles.

Designs are expected to be practical and cost effective. The competition was created due to the recent controversy surrounding the use of snowmobiles in the national parks and the proposed ban.

The competition's goal is to prove that snowmobile emissions are not as high as previously thought, and that significant reductions in noise and emissions levels can be achieved through the use of new technology.

Clean snowmobile is judged on events that evaluate noise level, acceleration, a 100- mile endurance ride, fuel economy, oral and written design reports, overall handling, hillclimb, emission levels, cold start, static display, and cost. The team consists of an average of twenty-five students.
