What is the quattro system on the Audi A8 and how does it enhance performance?

I've heard about quattro in relation to Audi cars, but I'm not sure what it actually does and how it impacts the driving experience. Can someone explain?

The quattro system is Audi's all-wheel drive system that distributes power to all four wheels for better traction and handling. It uses sensors and a central locking differential to constantly adjust power delivery to each wheel, resulting in better performance and control.

As someone who has driven the Audi A8 with and without the quattro system, I can definitely say that it makes a noticeable difference in terms of handling and cornering. It provides more stability and grip, especially in adverse weather conditions.
