Offered as an option with the Porsche Active Suspension Management (PASM) system, Porsche Dynamic Chassis Control (PDCC) is a set of active anti-roll bars that under normal driving conditions can eliminate body roll to improve handling, stability, and comfort. PDCC can also de-couple the anti-roll bars to maximize wheel articulation when off-roading, improving traction. Other new features include Dynamic Curve Lights which help illuminate around corners at night, rollover sensors that automatically activate the curtain airbags and seatbelt pre-tensioners in certain accidents, and updates to the standard Porsche Stability Management (PSM) system which includes brake pre-loading, off-road ABS, and Trailer Stability Control. Finally, every Cayenne gets a “Sport” mode for more aggressive powertrain response.
