![]() ![]() The package comprises dynamic gearbox mounts, a performance display, a digital and analogue stopwatch and the SPORT PLUS button. The optional Sport Chrono Package makes your driving experience priceless thanks to an even sportier tuning of throttle response and handling characteristics. ![]() Time is precious and every hundredth of a second counts. This enables intelligent adaptation of damper stiffness for the selected mode, optimising contact between each individual tyre and the road and reducing pitch. ![]() Sensors record the body movements that accompany powerful acceleration, braking or uneven road surfaces. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels in accordance with the selected mode. Depending on the mode selected, therefore, PASM can be both sportier and more comfortable than the standard chassis. In addition, the suspension is lowered by 10 mm.įorward 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. PASM actively and continuously regulates the damping force for each wheel according to the road conditions and driving style. Optional PASM, the electronic damping control system, suits the new Boxster models down to the ground. (The button with the shock absorber image ) PASM = Porsche Active Suspension Management When sudden braking is detected, the brake assist function applies maximum brake pressure to all four wheels. Maximum braking power is therefore achieved much sooner. With the braking system having been precharged, the brake pads are already in light contact with the brake discs. If you suddenly release the accelerator pedal, PSM automatically readies the braking system. PSM has been enhanced and now includes two additional functions: precharging of the brake system, and brake assist. 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. For an even sportier drive, PSM can be deactivated. The integrated ABS can further reduce the braking distance. 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). 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. If this direction deviates from the desired course, PSM initiates braking interventions targeted at individual wheels in order to stabilise the vehicle. Using this information, PSM computes the actual direction of motion. Sensors continuously monitor driving direction, speed, yaw velocity and lateral acceleration. PSM, which comes as standard, is an automatic control system that stabilises the vehicle at the limits of dynamic driving performance. ![]()
