Why do Audi A7 models have a low ground clearance?

I've noticed that Audi A7 models have a relatively low ground clearance compared to other luxury sedans. Is there a particular reason for this design choice, and what are the potential advantages or disadvantages of having a low ground clearance?

Having a low ground clearance can improve the handling and stability of the car, as it lowers the center of gravity. However, it can also make the car more prone to damage from rough roads or speed bumps.
