PASM, PSM or SPORT what does it mean?
PSM = Porsche stability Management
(Button Marked “PSM OFF”)
PSM, which comes as standard, is an automatic control system that stabilises the vehicle at the limits of dynamic driving performance. Sensors continuously monitor driving direction, speed, yaw velocity and lateral acceleration. Using this information, PSM computes the actual direction of motion. If this direction deviates from the desired course, PSM initiates braking interventions targeted at individual wheels in order to stabilise the vehicle.
Under acceleration on wet or low-grip road surfaces, PSM improves traction using the ABD (automatic brake differential) and ASR (anti-slip regulation) functions, giving an agile response. When ‘Sport’ mode is selected on the optional Sport Chrono Packages, the PSM intervention threshold is raised to enable greater driver involvement – particularly at speeds of up to approximately 70 km/h (45 mph). The integrated ABS can further reduce the braking distance. For an even sportier drive, PSM can be deactivated. However, it is automatically reactivated for your safety if either of the front wheels (in ‘Sport’ mode, both of the front wheels) requires ABS assistance. ABD remains permanently active. PSM has been enhanced and now includes two additional functions: precharging of the brake system, and brake assist. If you suddenly release the accelerator pedal, PSM automatically readies the braking system. With the braking system having been precharged, the brake pads are already in light contact with the brake discs. Maximum braking power is therefore achieved much sooner. When sudden braking is detected, the brake assist function applies maximum brake pressure to all four wheels.
PASM = Porsche Active Suspension Management

Optional PASM, the electronic damping control system, suits the new Boxster models down to the ground. PASM actively and continuously regulates the damping force for each wheel according to the road conditions and driving style. In addition, the suspension is lowered by 10 mm.
Forward thrust | Chassis The driver can select between two different modes: ‘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 both 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 in accordance with the selected mode.
Sensors record the body movements that accompany powerful acceleration, braking or uneven road surfaces. This enables intelligent adaptation of damper stiffness for the selected mode, optimising contact between each individual tyre and the road and reducing pitch.
Sport Chrono Package
(Button Marked “SPORT”)
Time is precious and every hundredth of a second counts. The optional Sport Chrono Package makes your driving experience priceless thanks to an even sportier tuning of throttle response and handling characteristics.
The package comprises dynamic gearbox mounts, a performance display, a digital and analogue stopwatch and the SPORT PLUS button. When this is pressed, optional Porsche Active Suspension Management (PASM) switches to ‘Sport’ mode for harder damping and more direct steering and therefore, even more intensive road holding.
The trigger threshold for PSM is raised. Agility is perceptibly enhanced when braking for corners with PSM, allowing even sportier braking and exit acceleration. For even greater dexterity, PSM can be set to standby while the car is still in SPORT PLUS mode. For safety, it is set to intervene automatically only when ABS assistance is required.
In conjunction with optional PDK, the Sport Chrono Package comes with two additional functions for a sporty drive that borders on a motorsport experience. The first is ‘Launch Control’, which is designed to produce a racing start.
The second function is the involving ‘motorsport-derived gearshift strategy’. Using this, Porsche Doppelkupplung (PDK) is geared up for the shortest possible shift times and optimum shift points, while torque boosts during gear changes provide the maximum acceleration available. This involving experience is further enhanced by overrun downshifts and the throttle-blip function for uncompromising driving pleasure.
An additional display in the steering wheel or either the instrument cluster indicates the SPORT or SPORT PLUS buttons and, with PDK, Launch Control have been activated. In conjunction with the optional Porsche Communication Management (PCM), a special display enables you to view, store and evaluate lap times or other driving times. It shows the total driving time, lap distance, lap number and lap times recorded so far.
Sport Chrono Plus
(Button Marked “SPORT PLUS”)
On request, the new, optional Porsche Communication Management (PCM) can be combined with the Sport Chrono Package Plus. In addition to the functions of the Sport Chrono Package, it includes a personal memory function, which can be controlled using the PCM, and a performance display for evaluating lap times.
PMS
Premenstrual syndrome (PMS) (also called PMT or premenstrual tension) is a collection of physical and emotional symptoms related to a woman’s menstrual cycle. Something you can’t switch on or off! It’s not really got anything to do with your Porsche.
