New Porsche Cayenne Turbo S Unveiled | Part Two

Even in its 'basic‘ trim and configuration the engine is easily able, through its strong and sturdy components, to meet the highest loads and requirements. Particular features of this four-valve power unit are VarioCam technology allowing a cam adjustment angle of 40o, as well as integrated dry sump lubrication for reliable lubrication of all engine components even under extended periods of high lateral acceleration. Configured in closed deck design, the crankcase is closed at the top by a cover plate resting on the cylinder head and forms a complete, self-contained system together with the cylinder cooling ducts in the interests of a very high level of stiffness. Able to run at an extreme angle of up to 45o both in longitudinal and lateral direction, the engine is perfectly suited for even the toughest off-road conditions.

Reflecting the supreme performance of the Cayenne Turbo S, the development engineers have increased brake power accordingly, the new model featuring even larger brake discs with larger callipers than on the Cayenne Turbo. To be specific, the diameter of the front brake discs is up to 380 mm from 350 mm (14.96 - 13.78"), the diameter of the rear brake discs has been increased to 358 from 330 millimetres (14.09 - 12.99"). The engineers have also designed new cooling ducts and achieved an increase in heat dissipation by 10 per cent. In standard trim the Cayenne Turbo S rides on 20-inch SportTechno design alloy wheels running on road tyres measuring R 275/40 Y. A tyre pressure control system is also featured as standard.

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.

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.
