Why does the Audi A8 use an active electromechanical suspension system?

I've noticed that the Audi A8 has an active electromechanical suspension system instead of traditional air suspension. Can you explain the benefits and drawbacks of this system and why Audi chose to use it?

The active electromechanical suspension system in the Audi A8 allows for more precise control and adjustment of the suspension in real-time, resulting in improved handling and comfort on different road surfaces.

Using an active electromechanical suspension system also allows Audi to implement advanced safety features, such as active suspension management and predictive suspension control, which can improve stability and reduce the risk of accidents.
