Why does the Audi A8 have adaptive air suspension and how does it work?

I've noticed that the Audi A8 is equipped with adaptive air suspension. Can you explain the purpose and functionality of this feature?

Adaptive air suspension in the Audi A8 allows for a smoother and more comfortable ride by adjusting the suspension to changing road conditions. It works by using sensors to detect variations in the road surface and adjusting the firmness of the air springs accordingly.

The main advantage of adaptive air suspension in the Audi A8 is its ability to provide a customizable driving experience. By selecting different driving modes, such as Comfort or Dynamic, the suspension can adapt to your preferred level of firmness and handling.

In addition to a more comfortable ride, the Audi A8's adaptive air suspension also helps improve handling and stability. By lowering the car's center of gravity in Dynamic mode, it can provide better cornering and reduce body roll.
