A New, Top of the Range Porsche Cayenne Turbo S Unveiled

A new, supreme top-of-the-range model is taking over the leading position within the Porsche Cayenne range; second only to the Carrera GT, the Cayenne Turbo S is the most powerful Porsche homologated for road use. Benefiting from careful improvement and on-going development of the turbocharger system, the eight-cylinder bi-turbo power unit develops maximum output of 520 bhp at 5,500 rpm, 70 bhp more than the Cayenne Turbo. Maximum torque of 530 lb-ft, in turn, is maintained consistently all the way between 2,750 and 3,750 rpm. This impressive output is reflected by truly outstanding performance on the road. The Cayenne Turbo S accelerates to 60 mph in 4.8 seconds, sprints from 50 75 mph in fifth gear in 5.4 seconds, and has a top speed of 168 mph.

Subtle external differences identify the new model; 20-inch SportTechno design alloy wheels, four exhaust tailpipes, the model designation at the rear and, if ordered by the customer, paintwork in Navy Blue Metallic, which is exclusive to this model. Under the bonnet, however, there are significant changes.

Upgraded Turbocharger System

The 4.5-litre V8 engine featured in the Cayenne Turbo S remains unchanged in principle, modification of the two intercoolers serving to boost both engine output and torque to a new level of performance. Fitted between the turbochargers and the throttle butterfly, the intercoolers serve to cool the compressed air supplied to the engine, improving the cylinder charge in the process.

The heat exchangers fitted in front of the wheel arches, together with the air supply and discharge ducts, are now made completely of aluminum and are 0.51" larger than on the Cayenne Turbo, ensuring a much higher level of efficiency and, at the same time, a significant improvement of flow conditions in the radiator, with the loss of pressure loss down by more than 50 per cent.

Six-Speed Automatic Transmission

Like the engine, the six-speed Tiptronic S automatic transmission is perfectly prepared for the supreme power and torque to be conveyed to the wheels, with gearshift points adjusting infinitely to the driver's style of motoring and the route he or she is taking.

Benefiting from the usual Porsche standard, the driver is also able to shift gears manually via buttons on the steering wheel. The additional option to shift gears instantaneously by briefly flicking the selector lever forwards or backwards serves above all to ensure a safe and smooth gearshift process when driving off-road.

Four-Wheel Drive

Transmission of power to all four wheels is elementary to the supreme driving dynamics offered by the Cayenne. Permanent Porsche Traction Management (PTM) all-wheel drive transmits 62 per cent of the engine's power to the rear wheels and 38 per cent to the front wheels in the basic mode. Via a multiple-plate coupling operated by an electric motor and controlled electronically, power distribution may be varied as a function of driving conditions with up to 100 per cent of engine power going to the front or rear, depending on current requirements. This enables the Cayenne Turbo S to convey the supreme power of the bi-turbo engine to the road under dry conditions, without the supply of torque being cut off. The result, therefore, is optimum acceleration under full power for supreme performance on the road.

Chassis and Suspension with Air Springs

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.
