Used on Audi V8 starting from 1990.
System type: Permanent or semi-permanent four-wheel drive.
V8 with automatic transmission:
Planetary gear centre differential with electronically-controlled multi-plate locking clutch
Torsen differential rear.
Open differential front.
V8 with manual transmission:
Torsen centre differential.
Torsen rear differential.
Open front differential.
How does the system perform: In on-road conditions the car will not be able to move if one front and both rear wheels lose traction altogether. Torsen effect with one wheel in the air still applicable to V8 with manual transmission, but will not happen on V8 with automatic transmission because center differential on this model offers 100% locking even when no torque is sensed on the spinning wheel.
