Mercedes-Benz uses two different adjustable suspension systems in its vehicles – Airmatic and Active Body Control (ABC). Airmatic, as the name implies, is its air suspension system which we discussed back in April of this year. ABC uses hydraulic fluid at tremendous pressures to actively change the stiffness of the springs inside the shock assemblies, changing vehicle dynamics and ride height. This can be done automatically based on sensor inputs and module programming, or at the push of a button located near the shifter.
