What is Audi A5's Quattro system and how does it improve performance?

I've heard a lot about Audi's Quattro system but I'm not sure how it differs from other all-wheel drive systems. Can someone explain its advantages and how it affects the driving experience?

The Quattro system is Audi's trademark all-wheel drive system that distributes power to all four wheels for improved grip and handling. On the road, it provides better traction and stability, especially in adverse weather conditions.

In terms of performance, the Quattro system allows for a more balanced distribution of power, resulting in better handling and control. It also works seamlessly with the car's electronic stability control system to further enhance overall performance.
