What does the Audi A6 Quattro system do?

I'm curious about the Quattro system in the Audi A6. What exactly does it do and how does it improve the car's performance?

The Quattro system is Audi's all-wheel-drive system, which distributes power to all four wheels for improved traction and handling. It uses a center differential and different torque split ratios to provide optimal performance in various driving conditions.

Having owned an Audi A6 with Quattro, I can attest to its excellent performance in all weather conditions. It really shines in snowy or wet roads, providing a sense of stability and control.
