On the Phaeton the basic configuration of the Torsen differential is selected such that the driving forces are normally distributed 50:50 across the front and rear axles. In case of slip, the Torsen differential diverts as much as 20 percent of the driving power to the axle with the better traction (max. 70:30, or 30:70). The adjustment is made steplessly and with no time delay. The locking effect of the Torsen differential increases automatically along with the load. In contrast to a "speed sensing" viscous lock, it operates in "torque sensing" mode. The advantage of this method is the lack of torsional stress when cornering, as the differential rotation speeds the vehicle seeks to bring about are in fact permitted.
