SDC3 (Selective Damping Control)

ZF

The heart of SDC3 is a frequency-dependent valve module that divides the damping force characteristics in the rebound direction into high and low-frequency damping forces.
In the case of low-frequency excitations – high cornering forces which occur during evasive maneuvers on the highway or when cornering on a country road – stabilizing, high damping forces are generated. The car is easier to steer, which increases safety. In case of high-frequency vibrations – small, rapidly occurring road unevenness from sources such as cobblestones, rough asphalt or tar patches – SDC3 operates on a low damping force level. The passengers remain isolated from the vibrations, which leads to a noticeable increase in comfort.
