How does Audi A6's Quattro all-wheel drive system work?

I've heard that the Audi A6 has a Quattro all-wheel drive system, but I'm not familiar with how it actually functions. Can someone explain it to me?

The Audi A6's Quattro all-wheel drive system uses a center differential to distribute power between the front and rear wheels in varying proportions, depending on the road conditions. This allows for better traction and control while driving on different surfaces.

The Quattro system also employs torque vectoring, which can send power to individual wheels in order to improve cornering and handling. So, not only does it provide better traction, but it also enhances the performance of the car.
