Why does the Audi A8 use air suspension?

I've noticed that a lot of luxury cars come equipped with air suspension, but what benefits does it provide for the Audi A8 specifically?

The Audi A8 utilizes air suspension to provide a smoother and more comfortable ride. Unlike traditional coil springs, air suspension can adapt to different road conditions and adjust the car's height accordingly.

In addition to a more comfortable ride, the air suspension in the Audi A8 also allows for dynamic handling and better control on corners. This is because it can adjust the firmness of the suspension depending on the driving mode selected.
