A snowmobile (known as a snowmachine in Alaska and parts of New England) is a land vehicle commonly propelled by track(s) at the rear and ski(s) up front for steering. In contrast, the first motor vehicle made to operate on snow, the Aerosan invented in Russia by Igor Sikorsky, was propeller-powered and running on skis.
Early snowmobiles used rubber tracks, however a modern snowmobile will have a track made of a kevlar composite. They are designed to be operated on snow and ice, and require no road or trail. Most snowmobiles are typically powered by two-stroke gasoline/petrol internal combustion engines. Four-stroke engines are becoming more and more popular in snowmobiles. Summertime occupations for snowmobile enthusiasts can also involve drag racing on grass, asphalt strips, or even across water. People who ride them commonly are known as snowmobilers. The three main types of riding are Snowcross/racing, trail riding and mountain climbing.
