Summary The SAE International Clean Snowmobile Challenge has changed with the times since its inception in the year 2000. The industry responded with cleaner and quieter snowmobiles. As a result@ the rules of the challenge had to be changed so that teams could not just purchase a modern snowmobile to compete. In 2006@ the Environmental Protection Agency (EPA) published its test procedures and standards for off-road vehicles@ including snowmobiles. This gave the students a target to beat in emissions and noise. Teams that were not cleaner and quieter than the standards could not win the challenge. The teams responded with innovative solutions that were watched closely by the snowmobile industry@ the single largest supporter of the challenge. Jay S. Meldrum
