How does the quattro system in the Audi A4 provide better handling and traction?

I've heard that the Audi A4 comes with quattro all-wheel drive, but I'm not clear on how it actually improves performance and driving experience. Can someone explain it to me in simple terms?

The quattro system in the Audi A4 uses a center differential to distribute power to all four wheels, providing better traction and handling in various road conditions, such as wet or slippery surfaces.

The quattro system not only improves performance and handling but also enhances safety, as it helps prevent loss of control and improves braking stability.

One of the main advantages of the quattro system is that it allows for a more balanced distribution of power, resulting in a smoother and more stable driving experience.
