Torque Transfer Characteristics 

Haldex Gen IV is fast! With instant activation independent on differential speed. It provides high torque transfer from stationery independent of any wheel rotation.

Haldex Gen IV is activated regardless of whether the input shaft is rotating faster or slower than the output shaft. This is a major advantage for the dynamic stability of the vehicle in acceleration or deceleration in combination with cornering or manoeuvring.

The torque transfer characteristics are controlled by the ECU, using the vehicle management information to adjust oil pressure via a proportional pressure reducing valve. With the controllable torque transfer characteristics of Haldex Gen IV the vehicle performance does not need to be a compromise between traction, demanding high torque transfer, and manoeuvrability, demanding low torque transfer. The torque transfer is optimised for each driving situation - ensuring maximum safety and performance.
