When cornering, all four wheels of a car must cover varying distances. The task of the center differential is to compensate for the differences between front and rear axles, and to distribute engine power between front and rear wheels. The center differential is the heart of Audi's permanent all-wheel driveline. Depending on the driving situation and road conditions, the system automatically regulates the distribution of power within milliseconds. This takes place by means of either (depending on model) the Torsen® differential, Haldex™ clutch, or hydraulic multi-plate clutch. Influencing parameters in the control process include engine speed and torque, wheel spreads, and longitudinal and lateral acceleration.

RE: AWD front/rear power distribution?
The S4 is currently 50/50. It will soon be 40/60 after the RS4 is released. The TT is normally front wheel drive until the wheels slip where it can distrubute up to 50% to the rear wheels. Someone correct me if i'm wrong about that.
