PASM, the electronic damping control system, is standard in the 911 Carrera S models and available as an option for the 911 Carrera models. It actively and continuously regulates damping forces according to driving style and road conditions. In addition, the suspension is lowered by 10 mm.
PASM has two modes, which can be selected using a separate button on the centre console: ‘Normal’, which is a blend of performance and comfort, and ‘Sport’ where the setup is much firmer.
Sensors record the body movements that accompany powerful acceleration, braking or uneven road surfaces. In the 911, the number of sensors has been increased for improved data acquisition and even more efficient control interventions. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels in accordance with the selected mode.
In ‘Sport’ mode, the suspension is set to a harder damper rating. On uneven roads, PASM immediately switches to a softer rating, thereby improving contact between the wheels 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 automatically switches to a harder rating. Damping firms up, and driving stability and road safety are increased.
The results are tangible: increased driving stability, improved comfort and enhanced performance.
The PASM sports suspension is available as an option for the 911 Carrera Coupé models in conjunction with 20-inch wheels and Porsche Torque Vectoring (PTV) or Porsche Torque Vectoring Plus (PTV Plus).
The ride height is 20 mm lower than with the standard suspension or 10 mm compared with the PASM suspension. The springs are harder and shorter, and the anti-roll bars on the front and rear axles are stiffer. The front spoiler lip has a more sporty geometry, the rear spoiler extends even further. These not only further reduce lift at the front axle, but also provide downforce at the rear axle for improved aerodynamics and even better performance.
