Forget the small, modern snowmobiles with four-stroke engines. They are way less cool than these old monsters, like car-to-snowmobile modifications and sled weapons. Here are some of the greatest snowmobiles ever made.
Antarctic Snow Cruiser (often called "Penguin 1" or "Turtle")
The 55 ft 8 inches (17 m) long vehicle was designed between 1937 and 1939 by a team led by Thomas Poulter for their second expedition with Admiral Byrd in 1939.
The only way to get it from Chicago to Boston was to drive it across the country with a relaxing 10-13 mph (16-20 km/h) cruising speed. Later the Penguin 1 had some problems in the Antarctic: slip off from a too-narrow bridge and later sank into the snow because of its large, smooth tires and its 30-ton weight. After the crew installed some chains and spare tires, it was able to drive with a very low speed, they've cover 96 miles (154 kms) in 12 months.
The team has just left the Penguin 1, when the expedition returned to the US. Few years later an other expedition found it and made it fully operational, but they've left it somewhere at Little America in the Bay of Whales.
The location of the Antartic Snow Cruiser is now completely unknown.

The Soviet Sever-2 (North-2)
It was designed by the Soviet GAZ car factory in 1959, based on the Pobeda car (GAZ—M20). It had an AI-14 aircraft engine, which helped the Sever-2 to reach the cruising speed of 18-20 miles (30-35 kmh) per hour.
The armored NKL-26
It was used by the Soviet Union during the WWII. It was made of plywood, had a ten-millimetre armor plate on the front and a 7.62 mm DT Machine gun.
"Ford on snowshoes" – the Model T Snowmobile
100 years ago a New Hampshire Ford dealer named Virgil D. White has invented the snowmobile, as we know it today. He started to sell conversion kits for Model T Fords (1921 "Mailman's Special" – pictured above.)

Tucker Sno-Cat 743 Double Drive, 1955
Different models with four independently mounted tracks have been used in the Arctica and Antarctic, but the most widely known is the 743. It was used during the Commonwealth Trans Antarctic Expedition in 1955-1958.
