WM, 4X00IN Component Arrangement - Levelling System
The Panamera models feature a levelling system with fully supporting air suspension on both axles and the electronically regulated damping system Porsche Active Suspension Management (PASM).
The air suspension with level control makes it possible to actively adapt the ground clearance of the Panamera to the current driving situation or to the vehicle load.
Depending on the load, various vehicle ride heights with various suspension characteristics can be achieved by increasing or decreasing the air volume. The amount of air needed for each air-spring strut is determined by means of a control unit and provided via an air supply consisting of a compressor, a solenoid valve unit and pressure accumulator.
