Our team designed a low-cost and lightweight electric snowmobile. We modified an existing Phantom snowmobile by replacing the gasoline engine with an electric motor powered by 24 lithium-ion battery cells. This allows the snowmobile to travel approximately 8 miles on a single charge while keeping the cost below $8,000 and weight under 441 pounds, making it suitable for use in environmentally sensitive polar regions. Major design changes included removing gasoline components and using a Goodyear belt drive system between the motor and sprocket for high efficiency and low noise.
