How Mercedes' Active Body Control works


Mercedes-Benz vehicles are notorious for their smooth ride quality. Bumps and ruts just don't bother passengers in Mercedes vehicles like they do in other cars. How does Mercedes do it? Jason Fenske from Engineering Explained is here to tell us.

In this video, Jason analyzes how two Mercedes suspension systems work. The base system is Active Body Control, and buyers can go one step further with Magic Body Control.

The key to both systems is the hydraulic dampers Mercedes uses. These dampers have hydraulic actuators that react to bumps by making the damper assembly shorter and ruts by making it longer. That allows the tire and wheel to move without the body moving nearly as much.

The next step is Magic Body Control, which uses a camera system to read the road ahead and actuate the hydraulic dampers as the car approaches road imperfections. This makes the ride even smoother.

Those hydraulic dampers can be used for other purposes as well. For instance, while the g forces of a corner make the car and its occupants lean to the outside of the turn, the hydraulics can be used to help the car lean into the turn like a rider on a motorcycle would. They can also be used to raise or lower the ride height for various purposes.

The car that Jason experienced these system in is the SL 63. After explaining how these systems work, he goes on to share his thoughts on that car.
