Why is the handling of the Audi A4 considered exceptional?

I've heard many people rave about the handling of the Audi A4. Can someone explain why it's considered superior compared to other cars in its class?

The Audi A4 has a Quattro all-wheel drive system, which provides excellent traction and responsiveness in all weather conditions.

The car's dynamic steering system adjusts the steering ratio based on speed, making it easier to maneuver in tight spaces and more stable at high speeds.
