What is Audi A7's Quattro system and how does it work?

I have heard that the Audi A7 uses a Quattro system, but I am not sure what that means. Can you explain the technology behind it and how it affects the car's performance?

The Audi A7's Quattro system is an all-wheel drive system that constantly monitors road conditions and distributes power to the wheels that need it most. This allows for better traction, stability, and handling, especially in adverse weather conditions. As for how it works, it uses sensors to detect wheel slip and then uses a center differential to distribute power to the front and rear axles as needed.
