Porsche Traction Management (PTM) is an active all-wheel drive system with an electronically variable, map-controlled multi-plate clutch, automatic brake differential (ABD) and anti-slip regulation (ASR).

Torque is distributed between the front and rear axles by means of the electronically variable multi-plate clutch. For the toughest off-road terrain, the differential can be locked using the PTM control on the centre console. With the aid of on-board sensors, the status of the car is continuously monitored and the front/rear split is adjusted to match changing driving conditions. The sensors are used to measure a range of values, including the rotational speed of all four wheels, the lateral and longitudinal acceleration of the car, and the current steering angle.

If, for example, the rear wheels threaten to lose traction under acceleration, a greater proportion of drive torque is automatically transmitted to the front axle by a more positive engagement of the multi-plate clutch. In addition, ASR minimises wheel spin. During cornering, the required level of engine torque is distributed to the front wheels to ensure excellent lateral stability.

In conjunction with advanced Porsche Stability Management (PSM), PTM ensures the perfect distribution of drive torque for optimum traction in all road scenarios, whether on long straights, through tight corners or on surfaces with different friction coefficients. If one of the wheels is about to lose traction, PTM uses the ABD function to apply the corresponding brake. As a result, more drive is automatically transferred to the opposite wheel. If both wheels on one

axle are in danger of slipping, ASR immediately intervenes and modifies engine output to maintain drive. As well as enhancing traction and active safety, Porsche Traction Management (PTM) offers exceptional handling and driving dynamics.

Standard on the Cayenne, Cayenne S, Cayenne GTS and Cayenne Turbo.

The Cayenne models that are equipped with eight-speed Tiptronic S also feature an auto start/stop function. If, for example, you stop at traffic lights and keep your foot on the brake pedal, the auto start/stop function will automatically cut the engine. Although the engine is not running, all audio and communication systems remain switched on and the standard climate control continues to maintain the selected temperature. The only changes you’ll perceive: peace and quiet and – thanks to greater fuel economy – also peace of mind.

The system is deactivated in certain situations, e.g. if the outside temperature is very high or the battery charge is low. The starter motor has been revised to cope with the additional demands of the system, and the battery charge and life are continuously monitored. The battery and starter motor are replacement parts that are subject to greater wear and tear with frequent use of the

auto start/stop function.

Standard on the Cayenne Diesel, Cayenne S, Cayenne S Hybrid, Cayenne GTS and Cayenne Turbo. Available as an option for the Cayenne in conjunction with the optional Tiptronic S.

DFI injects fuel directly into the combustion chamber at up to 120 bar with millisecond precision using electromagnetic injectors. The injector position and spray geometry have been carefully designed to improve output, torque, fuel economy and emissions. The swirling of the fuel as it enters each chamber increases the mixing of air and fuel, thereby enhancing combustion. By forming the air/fuel mixture directly in the combustion chamber, DFI contributes to engine cooling. As a result, it was possible to increase the compression ratio and therefore power and efficiency.

The outstanding feature of the eight-speed Tiptronic S is a particularly wide ratio spread. First gear is designed for optimum acceleration when pulling away and greater performance when tackling ascents and towing loads in off-road terrain. Top track speed is reached in 6th gear (in 7th gear on the Cayenne Diesel). The remaining upper gears are used to lower the engine speeds at highway speed, thereby enhancing fuel economy and occupant comfort. On the motorway in particular, driving at low engine speeds will significantly reduce the noise level inside the vehicle.

In automatic mode, the driver can influence gearshifts on the Tiptronic S using the throttle and brakes alone. Tiptronic S automatically adapts the gearshift points for performance driving – equally, if a more defensive driving style is detected, the system selects a gearshift point that offers maximum fuel economy. Under heavy braking, Tiptronic S shifts down to maximize engine

braking.

An electric pump is used to maintain the required pressure of the transmission fluid, e.g. to transmit high levels of torque at lower engine speeds.

The standard multifunction steering wheel in conjunction with Tiptronic S has two ergonomic switches for manual gear changes. One press forward with the thumb and Tiptronic S shifts up. One pull backwards with the index finger and Tiptronic S shifts down. Either the right or left-hand switch can be used. The result: an even more dynamic response when changing gear.

Standard on the Cayenne Diesel, Cayenne S, Cayenne S Hybrid, Cayenne GTS and Cayenne Turbo.

Optional for the Cayenne.

VarioCam Plus creates two engines out of one by steplessly adjusting the inlet valve timing and lift.

The system differentiates between normal road usage and performance driving, adapting seamlessly as driver inputs change. All functions are automatically controlled by the engine management system. All you experience is responsive acceleration and ultra-smooth running characteristics. Inlet valve timing is steplessly adjusted. To improve response when starting from cold, for example, VarioCam Plus selects the higher lift setting and retards valve timing.

At medium PMS and minimal load, the valve lift is lowered and timing advanced to minimize fuel consumption and emissions. At low engine speeds in particular, VarioCam Plus significantly

improves fuel economy. To achieve maximum power and torque, the valve lift is raised.

Overall, the system provides greater performance with relatively modest fuel consumption.

Standard on the Cayenne S, Cayenne GTS and Cayenne Turbo.

The V6 engine in the Cayenne features variable valve timing on both inlet and exhaust. The camshaft phase angles are continuously varied by the engine management system via rotary-vane adjusters.

On the Cayenne S Hybrid, the inlet valve timing is continuously adjusted.

The key benefits include better fuel economy and lower emissions. It also helps to generate greater power and torque – even at low engine speeds.

Standard on the Cayenne and Cayenne S Hybrid.

A high-performance engine can only maintain its maximum capability over a long service life if all components are operating consistently within a specific temperature range. The engines in the Cayenne models are therefore designed for efficient cooling.

In order to reduce the frictional losses that occur during warm-up, all Cayenne models feature comprehensive thermal management. Using intelligent control, it activates the different cooling circuits individually and on demand, thereby ensuring that the optimum operating temperature for the engine and transmission is reached more quickly. This minimizes friction – and keeps fuel consumption and CO2 emissions low.

The V8 engines have an enhanced coolant management system offering effective temperature control throughout the engine. While 20 percent of coolant flows longitudinally through the crankcase, the remaining 80 percent serves the cylinder heads using the proven cross-flow principle (from hot to cold).

On all Cayenne models, the piston heads are cooled using oil-spray jets integrated within the main lubrication system.

The entire cooling system is designed for prolonged heavy-duty use, e.g. off-road driving or heavy towing and carrying applications.

The V8 engines use dry-sump lubrication to ensure a consistent supply of oil in all load conditions, especially in off-road terrain. The oil reservoir is located inside the engine. This saves on space and reduces weight.

Oil is circulated around the V8 engines using a demand-driven pump. This has been designed for the toughest driving scenarios on and off road, including performance driving and extreme gradients.

The V6 engines have a wet-sump lubrication system. Ensuring a reliable supply of oil, whatever the driving conditions.

The Porsche ‘S’ has long been a mark of heightened sports performance and abundant reserves of power. On the Cayenne S, it also stands for strength, agility and efficiency.

At the heart of the car is a naturally aspirated 4.8-litre V8 engine featuring direct fuel injection (DFI), VarioCam Plus and a two-stage intake manifold. This helps to keep fuel consumption and emissions low, while ensuring maximum output. In short: 294 kW (400 hp), maximum torque of 500 Nm and a top speed of 258 km/h. The Cayenne S accelerates from 0 to 100 km/h in as little as 5.9 seconds. Fuel consumption has been reduced by up to 23% and CO2 emissions by as much as 26%.* The weight of the car has also been lowered by 180 kg*.

Drive is transmitted to the road with smoothness and precision by the eight-speed Tiptronic S,

which is now standard equipment and includes gearshift controls on the steering wheel. The result: optimum use of the available power reserves.

Of course, to apply exceptional power like this effectively, it needs to be harnessed and controlled. For example, by Porsche Traction Management (PTM). On the Cayenne S, this active all-wheel drive system features an electronically variable, map-controlled multi-plate clutch, an automatic brake differential (ABD) and anti-slip regulation (ASR). Working in conjunction with advanced Porsche Stability Management (PSM), PTM ensures the required torque split in every driving scenario. On or off road. During performance driving, as well as on leisurely journeys or when towing heavy loads.

The black slats on the air intakes make them appear larger, and the car wider. Other distinctive features include the 18-inch Cayenne S III wheels.

The Porsche ‘S’. A mark to which the Cayenne S holds true.
