 The Snow Trac was successfully used in explorations in the Antarctic and the Arctic and attained production numbers of 2000 units and only ceased production in 1981 when Volkswagen discontinued the European production of the engines used to power the machines.Bombardier, of Canada, was also successful and is still in business today making aircraft, rail vehicles, snowmobiles, ATVs and watercraft.While Kristi was commercially unsuccessful, it did outlive and out produce other companies that developed "snowplanes" largely because early in the life of the company they switched production from snowplanes to snowcats.
