New developments: rear-axle steering, air suspension, roll stabilisation
This format provides the optimal basis for the active chassis systems, which are analysed and synchronised by the integrated Porsche 4D Chassis Control system. The system works in real time, optimising handling even further. With the exception of the active PASM damper system (as standard with the Cayenne S), all other chassis systems are new developments. For the first time, the Cayenne is available with electric rear-axle steering. The system, tried and tested both in the 911 and the Panamera, improves agility on bends and stability when changing lanes at high speeds. The reduced turning circle also makes everyday handling of the SUV easier.
The optional adaptive air suspension with new three-chamber technology significantly increases the spread between a sporty, firm connection and the driving comfort expected of a touring car. Just as before, the system enables adjustments to the ground clearance on rough terrain. With the optional Porsche Dynamic Chassis Control (PDCC) roll stabilisation, sporty drivers benefit by changing from a hydraulic to an electric system. This switch is made possible by a powerful 48-volt vehicle electrical system. Shorter response times enable even more precision in the driving dynamics – and even more comfort on moderate drives.
World première: Porsche Surface Coated Brake with tungsten-carbide layer
With the innovative Porsche Surface Coated Brake (PSCB), the sports car manufacturer is once again assuming a pioneering role in the development of high-performance brakes. This world first is available as an option for all Cayenne models and consists of a cast-iron disc with a tungsten-carbide coating. This finish increases the friction values and wear and brake dust are reduced. The brake, exclusive to Porsche, is also visually impressive: The brake callipers are painted white, while the surface of the discs develops a unique gloss level after bedding-in. The PSCB is only available in combination with the 20-inch and the 21-inch wheels. The PCCB ceramic brakes remain the top system in the range.
New Sport Chrono Package with PSM Sport
The new Cayenne offers even more potential when it comes to sporty performance. Porsche has redeveloped the Sport Chrono Package based on the model of the sports car. The Mode button on the steering wheel is one clear indicator of this approach. As well as the Normal, Sport and Sport Plus driving modes, the driver can select an individually configurable mode. Pressing the Sport Response button in the centre activates the engine and transmission maps, which are calibrated for maximum performance. The Sport Chrono Package also includes a separate PSM Sport mode, in which the driver can utilise the new Cayenne’s full driving dynamics.
