Press Release
Yet a further feature is that all models now have a longer final drive ratio.
The manual gearbox is combined as standard with the Porsche Drive-Off Assistant referred to as PDOA for short. This assistance system automatically intervenes in the brakes whenever required to prevent the vehicle from rolling back when the driver disengages the clutch. The automatic transmission also offers the same kind of roll-back prevention, where the Hill-Holder function when setting off in a forward gear on an uphill gradient prevents the Cayenne from rolling downhill.
Sports Button for extra dynamism
The new models in the Cayenne range give the driver the option, simply by pressing the new Sports Button featured as standard, to choose either the Standard or Sports suspension. In the Sports mode the engine responds even more spontaneously, and models featuring automatic transmission, air suspension and PASM Porsche Active Suspension Management come additionally with an even more sporting and dynamic configuration.
New option: PDCC for Anti-Roll Stability
Both the Cayenne and the Cayenne S come as standard with steel spring suspension, while the Cayenne Turbo features air suspension incorporating PASM Porsche Active Suspension Management. This very special suspension also available as an option on the Cayenne and Cayenne S offers not only adjustable damper control with three different settings, but also the option to lower or raise the entire body of the vehicle to various levels, with the Cayenne thus offering very substantial ground clearance of 217 millimetres or 8.54“ for tough off-road conditions.
PASM is now available for the first time together with PDDC Porsche Dynamic Chassis Control as a new option for enhanced Anti-Roll Stability. This infinite anti-roll control system limits body roll in bends and balances out the car's angle under nearly all driving conditions, with the body showing only a slight movement in very dynamic and sporting situations.
As a result, the Cayenne offers not only a significant improvement in handling, but also an equally significant improvement of driving stability and motoring comfort.
PDCC is made up of two active anti-roll bars with hydraulic swivel motors integrated in the front and rear axles instead of conventional anti-roll bars. Responding very quickly and building up significant pressure of up to 180 bar, PDCC, through its active anti-roll bar configuration, is able to generate appropriate support and counter-forces before the body of the Cayenne is able to sway to the side in a fast bend.
PTM for excellent traction
Intelligent PTM Porsche Traction Management offers an ideal combination of very good onroad and offroad driving characteristics, distributing engine power in the standard mode at a 62:38 front-to-rear ratio. Depending on current requirements, a multiple-plate clutch operated by an electric motor and controlled electronically is able to vary the division of power as required, if necessary feeding up to 100 per cent of the engine's power and torque either to the front or to the rear wheels.
PTM not only responds to a lack of traction, but also incorporates sensors measuring the speed of the vehicle, lateral acceleration, the steering angle, and the position and use of the gas pedal in order to provide enhanced control under the most extreme dynamic driving conditions. In difficult terrain, PTM is also able to use the offroad low-range gear integrated in the power divider with its transmission ratio of 2.7:1, also applying a 100 per cent longitudinal lock should any of the wheels lose ground contact.
PSM with an extended range of functions
Featured as standard in the Cayenne, PSM Porsche Stability Management communicates permanently and consistently with PTM Porsche Traction Management, but only intervenes when the Cayenne reaches the limits to driving physics. A sub-function of the anti-lock brake system, in turn, detects application of the brakes on loose ground, in response periodically increasing wheel slip during brake cycles. This offroad ABS function is therefore particularly advantageous on snow, sand or fine gravel, building up a wedge of the material beneath the vehicle in front of the wheels to provide an additional effect on loose ground or slippery surfaces.
The new Brake Assistant and the pre-loading function on the brakes significantly improves the overall quality and efficiency of the brake system: As soon as it detects application of the brakes in an emergency by means of information provided by the hydraulic PSM control unit, the Brake Assistant builds up the brake pressure required for maximum stopping power. The brake pre-loading function, in turn, develops higher pressure within the brake system immediately when the driver takes his foot abruptly off the gas pedal and therefore helps to shorten the stopping distance required under application of the brakes. Further improved Trailer Stability Control, finally, detects any pendulum motion on the trailer and intervenes by applying the brakes individually as required in the interest of enhanced brake stability.
Even higher standard of passive safety
Two full-size airbags for the driver and front passenger, two thorax side airbags, and two curtain airbags in the roof frame covering both the front and rear side windows ensure an exceptionally high standard of passive safety inside the Cayenne. With the exception of the centre seat at the rear, all seats come moreover with belt latch tensioners as well as belt force limiters on the front seats giving the occupants riding in the Cayenne optimum safety at all times.
Apart from collisions in a longitudinal and lateral direction, the sensors now for the first time also detect the risk of the vehicle rolling over. This function is provided by a new rolling rate sensor in the airbag control unit activating the belt latch tensioners and curtain airbags in an emergency.
Dynamic Curve Lights
Bi-xenon headlights featured as standard and supplemented by both Static and, for the first time, Dynamic Curve Lights enhance active safety to an even higher level in the Cayenne Turbo. The Dynamic Curve Lights are activated from a speed of just 3 km/h or 2 mph, ensuring better illumination of winding roads ahead. The Static Curve Lights, in turn, provide even better illumination of the road ahead close up to the vehicle.
This headlight system is also available as an option on the Cayenne and Cayenne S fitted as standard with H7 projection headlights.
New attractive features
Now entering its second generation, Porsche's Sports Utility Vehicle comes with an even wider range of individual features and items of equipment. The automatic tailgate available as an option, for example, enables the driver to comfortably open and close the rear lid at the touch of a button. The new, optionally available loading area management comprising features such as a rail system integrated in the floor of the luggage compartment and a partition net allows even safer and more convenient stowage of luggage within the luggage compartment.
A new feature is the optionally available, highly attractive leather upholstery with natural leather in Black/Chestnut Brown.
For the first time the Cayenne is now also available with 21-inch wheels boasting ten-spoke design on the Cayenne Sports wheels and multi-spoke design on the SportPlus wheels. And to provide an even more sporting and dynamic character, the Cayenne S with Porsche's Tiptronic S transmission is also available with a sports exhaust system featuring two double tailpipes.
