How does the Audi A4's quattro system enhance its handling?

I've heard that the Audi A4 has an impressive all-wheel drive system called quattro, but I'm curious as to how it actually improves the car's handling. Can someone explain the technical aspects of quattro and how it contributes to the A4's performance?

The quattro system in the Audi A4 utilizes a center differential to distribute power between the front and rear wheels, providing better traction and stability in various driving conditions. As someone who has owned an A4 with quattro, I can attest to its noticeable improvement in handling and cornering abilities.
