Porsche Active Suspension Management (PASM) Optional PASM, the electronic damping control system, actively and continuously regulates the damping force for each wheel according to the road conditions and driving style. In addition, the suspension is 10 mm lower than that of the standard setup. The system is always active in the background, ready to assist you automatically without you having to switch it on. Nevertheless, two modes are available at the push of a button so that you can adapt handling to suit your preferred driving style: ‘Normal’ which is a blend of performance and comfort, and ‘Sport’ where the setup is much firmer. Depending on the mode selected, therefore, PASM can be sportier and more comfortable than the standard chassis. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels optimally in accordance with the selected mode. Sensors record all wheel and body movements. This enables intelligent adaptation of damper stiffness for the selected mode, optimizing contact between each individual tire and the road for even less roll and pitch. In ‘Sport’ mode, for example, the suspension is set to a harder damper rating. On uneven roads, PASM immediately switches to a softer rating, thereby improving contact between the tires and the road. When the road surface improves, PASM automatically reverts to the original, harder rating. If ‘Normal’ mode is selected and the driver’s style becomes more assertive, PASM switches to a harder rating to increase driving stability and road safety.
