There is no doubt that the torsion differential works correctly and with sense in poor grip on the road. Therefore, here is an explanation of what happens in the Audi Quattro transmission on a dry road: as already mentioned, the front wheels travel a longer distance than the rear wheels when cornering, since the rear wheels describe an arc of a smaller radius.
In this regard, the torsion differential transmits more drive force to the rear axle (due to their lower turnover), which maintains the desired trend towards the inside of the turn.
If the speed is too high and at the same time one of the rear wheels is turning, then the differential immediately transfers more drive force to the currently slower front wheels. The system's quick response helps the front wheels pull harder and the vehicle stabilizes. Effect: Driving characteristics are improved in the cornering range.
