How does the Audi A8's intelligent all-wheel drive system work?

I've heard that the Audi A8 has an advanced all-wheel drive system, but I'm not sure how it differs from other cars. Can you explain how it works and what benefits it provides?

The Audi A8's all-wheel drive system uses a center differential to distribute power to each wheel as needed, providing optimal traction and handling in all road conditions.

As a proud A8 owner, I can attest that the all-wheel drive system makes a noticeable difference in wet or snowy weather. I feel much more confident and in control while driving.
