Both Boxster models are equipped with Porsche Stability Management (PSM) as standard. While it cannot overcome the laws of physics, PSM can provide additional control in difficult driving scenarios.
Here's how it works: When the new Boxster is in motion, PSM monitors the car's direction, speed, yaw velocity (speed of rotation around the vertical axis) and lateral acceleration. Based on this information, it can then calculate the actual direction of travel. If your Boxster begins to oversteer or understeer, PSM applies selective braking on the individual wheels to help bring it back into line. If the wheel approaches the threshold of skidding under braking, PSM uses a modified ABS to shorten the braking distance.
If you're accelerating on wet or other low-grip surfaces, PSM uses the integrated ABD (automatic brake differential) and ASR (antislip regulation) functions to help maintain traction and stability.
When 'Sport' mode is selected on the optional Sport Chrono package, the PSM threshold is higher, allowing greater driver involvement. If you'd rather enjoy your Boxster unassisted, the system can be set to standby at any time.
To enhance your safety, PSM remains present in the background and will only intervene under heavy braking where both front wheels are being controlled by ABS. All PSM inputs are more restrained and more precise, thus preserving the natural agility of the car. Although driving in a safe and prudent manner is the driver's ultimate responsibility, PSM does provide an extra margin of safety whenever you need it most.
