Magic Body Control is the amazing new bump-flattening technology in the new Mercedes S-class. It works by scanning the road ahead for bumps and pre-setting the adjustable air suspension accordingly.
In this video the first pass over the speed hump is with Magic Body Control active, and you can see the car staying level with the road and barely seeming to notice the bump.
In the second pass the system is inactive and there's noticeable pitching and squatting. From inside the car the difference is even more marked.
