How does the Audi A4's Quattro system improve handling?

I've heard that the Audi A4 has a Quattro all-wheel drive system. Can someone explain how this system helps with handling and performance?

The Quattro all-wheel drive system in the Audi A4 distributes power to all four wheels, providing better traction and improved handling on all types of road surfaces.

With the Quattro system, power is sent to the wheels with the most grip, allowing for better control and stability, especially on wet or slippery roads.
