How does the Audi A6's all-wheel drive (AWD) system work?

I've heard that the Audi A6 has a great AWD system, but I'm not familiar with how it actually functions. Can you explain how it works and what benefits it offers?

The Audi A6's AWD system, known as Quattro, uses a center differential and torque vectoring to distribute power to each wheel as needed. This allows for better traction and stability, especially in hazardous driving conditions.

With AWD, the Audi A6 is able to provide power to all four wheels instead of just two, significantly improving grip and handling. In normal driving conditions, it works as a front-wheel drive car, but can quickly shift power to the rear wheels when needed.

One major benefit of the Audi A6's AWD system is its ability to improve fuel efficiency by reducing power to the rear wheels when not needed. This makes it a practical choice for both performance and daily driving.
