A hybrid V-belt ( 4 ) has at least one tension carrier ( 2 ) and a plurality of blocks ( 6 ). The blocks function as support elements and are mounted on the tension carrier. The at least one tension carrier ( 2 ) comprises elastomeric material and is reinforced with a cord insert ( 12 ). The surfaces of the tension carrier ( 2 ) are transversely ribbed or undulated and are provided with cover layers ( 14, 16 ). To increase the fatigue strength of such hybrid V-belts, the cord insert ( 12 ) is, according to the invention, arranged directly on the lower radially inner cover ( 14 ). A direct contact between the cord ply ( 12 ) and the radially inner cover layer ( 14 ) results in the region of the zeniths ( 6 a, . . . ) of the lower block slot flanks.
