What is Audi A7's quattro system and how does it enhance the driving experience?

I've heard a lot about Audi A7's quattro all-wheel drive system, but I'm not entirely sure what it does or how it benefits the overall performance of the car. Can someone explain it to me in more detail? Thank you.

The Audi A7's quattro system is a standard feature that distributes power to all four wheels, ensuring maximum traction and stability in different driving conditions. This enhances the overall driving experience and allows for improved handling and control on the road.
