A BRP Ski-Doo snowmobile was selected and adapted by Clarkson University to win its second straight Society of Automotive Engineers (SAE) Clean Snowmobile Challenge. Ski-Doo models were also chosen by the second and third place teams in the internal combustion category and the winner of the Zero Emission category.
The snowmobiles entered are judged on many criteria, including emissions and noise, but they also have to be functional machines that can be trail ridden, so handling, comfort, endurance and the ability to pull loads factor in also.
Clarkson started with a Ski-Doo MX Z model featuring the Rotax ACE 600 engine and modified the fuel and ignition systems to automatically run on ethanol blended fuels that ranged from zero to forty percent ethanol alcohol. Student engineers then added a compact, one-of-a-kind catalytic converter they designed to further clean up emissions. In taking the overall championship, the team also took honours for Best Handling, Quietest, Best Ride, Best Value – which accounts for price, fuel economy and performance – and Most Practical Solution – which balances cost and noise reduction.
