Why is the ride quality of the Audi A8 so smooth?

I've noticed that even on bumpy roads, the Audi A8 still feels incredibly smooth. What technology or features contribute to this impressive ride quality?

The Audi A8 has an adaptive air suspension system that constantly adjusts to changes in terrain in order to maintain a comfortable ride.

In addition to the air suspension, the Audi A8 also has active noise cancellation technology that helps to reduce vibrations and bumps felt inside the cabin.

One of the key factors in the smooth ride of the Audi A8 is its use of aluminum in the body construction, which helps to reduce weight and stiffness, resulting in a less jarring ride.
