An endless track for traction of an off-road vehicle, such as an agricultural vehicle, an industrial vehicle (e.g., a construction vehicle) or a military vehicle, is provided. The endless track comprises an elastomeric belt-shaped body comprising an inner surface for facing wheels of the vehicle and a ground-engaging outer surface for engaging the ground. The endless track also comprises a plurality of elastomeric lugs, such as drive/guide lugs projecting from the inner surface and/or traction lugs projecting from the ground-engaging outer surface. An elastomeric lug may have a material composition defining an arrangement of zones of different materials which comprises a plurality of zones of different elastomeric materials. The elastomeric lug may exhibit a desired variation of a material property (e.g., a modulus of elasticity) across the arrangement of zones of different materials. A zone of the elastomeric lug may have a dedicated function, such as a sacrificial zone or a wear indicator zone. An elastomeric drive lug may comprise an uneven drive surface, such as an angled or curved surface, for engaging a drive member of a drive wheel of the vehicle.
