2006 Porsche Cayenne Turbo S

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; SportTechno design 20-inch 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.

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.

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. 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.

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.
