Why is the Audi A8 equipped with air suspension?

I noticed that the Audi A8 comes with air suspension. What is the purpose of this feature and how does it work?

The air suspension in the Audi A8 serves multiple purposes. It provides a smoother and more comfortable ride for passengers, as well as improves handling and stability. The adjustable nature of the suspension also allows for different driving modes, such as a more sporty or comfort-focused setting. From my personal experience, I highly recommend opting for the air suspension, as it greatly enhances the overall driving experience.
