'Skyhook' Suspension Continuous Dampening Adjustment of Suspension The Skyhook active suspension system (SUSP), a world-wide first available only on Maserati models, continually and automatically adjusts the stiffness of the suspension, thereby adapting the vehicle response to different road and driving conditions at a speed many times faster than the systems available to date; this suppresses body roll and pitching, for improved ride comfort and more dynamic sports handling. The "Sport" button on the center console allows the driver to choose between a soft setting for optimal comfort or a stiff setting for maximal sports handling. http://www.maserati.com/esImages/20021030/sky_hook_G.jpg The selected suspension stiffness will also automatically drive the different settings of the traction control system (ASR), as well as the gear change mode for Cambiocorsa versions.
The easiest way to tell if you have Skyhook, look at the center console. If you have a button that says "Sport" you have Skyhook, if it says "PWR" you do not have the suspension.
