Less CO2

Mild hybrid concepts were developed as a bridging technology to reduce the CO2 emissions of new vehicles. Here, the power of the combustion engine is supplemented by that of a belt-driven starter generator.

Extreme requirements

Mild hybrid systems require an extremely powerful drive belt, as the power transmission regularly alternates between the starter generator and the crankshaft pulley. To withstand these enormous loads, optibelt OLYMPIA mild hybrid V-ribbed belts contain aramid fiber-reinforced EPDM compounds and high-performance aramid cords.
