How do the Audi A7's quattro system enhance its handling and performance?

I'm interested in learning more about the Audi A7 and its all-wheel drive quattro system. How does this system work, and how does it improve the car's overall handling and performance?

The Audi A7's quattro system uses a center differential to distribute power to all four wheels, providing better traction and control in different driving conditions. It also helps improve the car's cornering and stability.
