Porsche Traction Management for supreme driving dynamics
Porsche Traction Management (PTM) has a significant effect on the supreme standard of driving dynamics the Cayenne is able to offer. The longitudinal lock masterminded by map control and the optional differential lock on the rear axle included in the Advanced Off-Road Technology Package not only respond to a lack of traction on the front and rear axles, but also interact with sensors measuring the speed of the car, its lateral acceleration, the steering angle and the position of the throttle pedal, allowing PTM to calculate the optimum degree of differential lock on both axles at all times and thus distribute exactly the torque required to each axle. PTM thus ensures a high level of agility in bends plus exemplary driving stability when changing lanes, both at high speeds and when driving on ice and snow at a lower speed.
Superior chassis and suspension with air springs and adaptive self-levelling
With the chassis and suspension of the entire Cayenne model series being developed from the start to meet the greatest demands and requirements, Porsche was able to carry over the entire concept of this exceptional car to the new top-of-the-range model without making any changes. The front axle with rack-and-pinion steering comes in double control arm configuration, with the entire axle resting on its own subframe. The rear axle, in turn, is an elaborate multi-arm configuration also supported by a subframe.
The Cayenne Turbo S comes as standard with air springs allowing no less than six different levels of ground clearance for optimum conditions and driving qualities both at very high speeds and when driving off-road. Benefiting from integrated self-levelling, the suspension offers the further advantage of consistent ground clearance, regardless of the load the vehicle is currently carrying. And the automatic reduction in ride height is two steps down from the normal level makes a significant contribution to enhanced driving safety at the very high speeds the Cayenne Turbo S is able to achieve.
Variable damper system featured as standard
Porsche Active Suspension Management (PASM) also comes as standard on the Cayenne Turbo S. This electronic, variable damper adjustment system controls damper forces infinitely as required, depending on surface conditions and the driver’s style of motoring. As an example, PASM will intervene under very dynamic driving conditions involving powerful acceleration and application of the brakes, as well as on winding roads with many bends. A further advantage achieved in this way is the reduction of roll and body sway in the interest of enhanced smoothness.
Safety and equipment of the highest level
The excellent passive safety of the Cayenne Turbo S results not only from the use of the most modern materials such as high-strength steel throughout the body of the car, but also from the entire structure of the vehicle with three load levels above one another serving to absorb deformation energy.
Inside the Cayenne Turbo S, a wide range of airbags protects the occupants in a crash, examples being the driver, front passenger and thorax airbags as well as curtain airbags integrated in the roof frame and serving to protect the occupants at the rear.
This complete system of largely "invisible" safety elements is enhanced by a high level of equipment boasting full leather upholstery and trim throughout the interior as well as other comfort components. These include bi-Xenon headlights with dynamically controlled, static curve lights, electrically adjustable comfort seats at the front with a memory function and seat heating, as well as heated seats at the rear, automatic air conditioning, ParkAssist, Porsche Communication Management incorporating satellite navigation, and Bose Surround Sound System all featured as standard.
The Porsche Cayenne Turbo S goes on sale in the UK on 25 February, priced from £81,565 and including a Porsche Driving Experience programme.Published 5 January 2005
