A snowmobile drive track for travelling on various surfaces including icy surfaces, hardened snow surfaces and semi-hardened surfaces comprises an endless body having, on its ground engaging outer side, projecting profiles having peaks of different height. The first highest peak s bear on icy surfaces, while, on hardened snow surfaces, the second highest peaks also engage the ground; on semi-hardened snow surfaces, all peaks engage the ground.
