What is Quattro AWD and how does it work in the Audi A6?

I've heard that the Audi A6 has Quattro AWD, but I'm not sure what that means or how it actually works. Can you explain it to me in a technical and specific way?

Quattro AWD stands for 'quattro all-wheel drive' and it is a system that distributes power to all four wheels of the vehicle for improved traction, stability and handling. This system uses a combination of sensors, electronic controls, and a torque-sensing center differential to continuously monitor road conditions and distribute power accordingly. In short, it means better performance and control in all types of weather and road conditions.

As the name suggests, Quattro AWD has four wheel drive (rather than just two in a traditional front-wheel-drive vehicle) which means more power can be sent to the wheels with the most grip, improving acceleration and cornering capabilities. It also works seamlessly with the vehicle's stability control system to further enhance safety and performance on the road.
