As standard, all Panamera models are equipped with enhanced Porsche Stability Management (PSM), which maintains stability even at the limits of dynamic driving performance. Sensors continuously monitor the direction, speed, yaw velocity and lateral acceleration of the car. Using this information, PSM is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels to restore stability.
Under acceleration on wet or low-grip road surfaces, PSM improves traction – and agility – using the automatic brake differential (ABD), anti-slip regulation (ASR) and engine drag torque control (MSR).
When SPORT PLUS mode is selected on the optional Sport Chrono Package, the PSM intervention threshold is raised to allow a sportier driving style.
For a more dynamic experience, you always have the option to deactivate PSM. It is automatically reactivated, for your safety, only if you brake harder and either of the front wheels (in SPORT PLUS mode, both of the front wheels) requires ABS assistance. ABS and ABD, however, remain active at all times.
PSM includes two additional functions: pre-charging of the brake system – enabling full braking power to be achieved much sooner – and brake assist for maximum deceleration in emergency braking situations.
PSM therefore offers a high level of driving stability and safety combined with extraordinary agility.
