A snowmobile comprises a pair of steerable front skis and a pair of laterally spaced rear driving tracks. The engine and seat are located between and below the level of the top of the tracks. Each track encompasses a driving wheel and a front and rear ground or bogie wheel. The front bogie wheels are mounted to normally maintain a higher elevation than the rear bogie wheels, so that the forward portion of each track is normally spaced above ground level. Another embodiment places the normal position of both front and rear bogie wheels above the ground, with only an intermediate point of ground contact.
