The Cayenne S Hybrid has a 3.0-liter V6 supercharged engine. The charging effect of the compressor ensures high levels of torque, even at low engine speeds. The unit generates an output of 333 hp. 325 lb.-ft. of torque is available between 3,000 and 5,250 rpm, enabling a low-rpm, economical driving style while offering exceptional reserves of power.

At 288 volts, the electric machine has a maximum output of 47 hp. The benefits of the synchronous motor with inner rotor design are extremely compact dimensions and high levels of efficiency. It also acts as a starter motor and alternator. Working in tandem, both units provide a total output of 380 hp and maximum torque of 428 lb.-ft., propelling the car from 0 to 60 mph in just 6.1 seconds. These are the levels of acceleration you would usually expect from an eight-cylinder unit, but with a combined fuel consumption of the six-cylider.

On the parallel full hybrid system, the electric machine is integrated directly into the drivetrain. The hybrid module is positioned between the transmission and the combustion engine. The engine is engaged and disengaged using a specially designed decoupler.

The electronic engine management system receives all information on the driving and energy status and controls both drive systems to ensure optimum performance in any driving scenario. It shuts off the combustion engine and switches it back on. Thanks to the ultra-fast decoupler and instantaneous engine start-up, all of this goes unnoticed by the driver. Under moderate acceleration, the electric machine can power the vehicle independently using electricity alone. For example, for driving quietly through residential areas. In addition, it can be used to boost performance – for even faster acceleration.

The parallel full hybrid concept also comes into its own during performance driving. When the Cayenne S Hybrid is driven at high speeds and on overrun, the combustion engine is automatically disengaged from the drivetrain and shut off: the car continues to ‘coast’ along. Engine drag and the associated losses are eliminated and efficiency is increased at speeds of up to 96 mph..

The ‘e-power’ button can be used to expand the range in which the vehicle can be run solely on electric power, when heading out of a residential area, for instance. The throttle map is adapted so that the combustion engine is engaged later than in ‘Normal’ mode depending on performance requirements. This is activated via a button on the center console.

The hybrid system features a high-voltage nickel metal hydride (NiMH) battery consisting of 240 cells. It provides the electric machine with the energy required for the vehicle to drive short distances solely on electric power.

The compact battery is located under the loadspace floor in the luggage compartment. Weighing approximately 176 lbs, its dimensions are 16.8 in. x 36.5 in. x 11.3 in.

The battery is designed to last without the need for any maintenance throughout its entire life. As the electric machine also functions as a generator, it can charge the battery under certain

conditions when the combustion engine is in part-throttle mode and through energy recovery during braking. A special battery management and cooling system maintains a constant temperature and protects the battery from overheating. It also monitors the charge/discharge processes. As a result, the life of the battery is optimised and its suitability for everyday use ensured, while offering a high capacity: 1.7 kWh.

Systems that are usually dependent on the output provided by the combustion engine, such as climate control, power steering and brake assist, run solely on electricity on the Cayenne S Hybrid. As they do not rely on output from the engine, these functions remain active when the car is running in electric mode or when it is ‘coasting’ or gliding along with the engine turned off.

In summary: despite its six-cylinder powerplant, the Cayenne S Hybrid offers performance levels that are comparable with an eight-cylinder unit – but with significantly lower fuel consumption. Also when it comes to hybrid drives, we’ve taken a completely new path. Hardly surprising really, with a technology this convincing.

The Cayenne Diesel and Cayenne S Hybrid feature a permanent all-wheel drive system with self-locking center differential. This provides a standard torque split of 60 percent to the rear and 40 percent to the front. If one of the wheels is about to lose grip, the self-locking center differential transmits the torque to the axle offering the highest level of traction. The ASR and ABD systems work in the same way as in the PTM on the Cayenne, Cayenne S and Cayenne Turbo.

On the Cayenne Diesel and Cayenne S Hybrid, PTM also enables variable distribution of engine torque to the rear wheels, thereby enhancing steering precision and driving dynamics. Specifically, this means that when entering a corner at high speed, moderate brake pressure is applied to the inside rear wheel. This supports the steering motion of the car, thereby improving its cornering dynamics.

Standard on the Cayenne Diesel and Cayenne S Hybrid.

DFI injects fuel directly into the combustion chamber at up to 1740 psi 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 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 will automatically turn off 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.

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 engine in the Cayenne S Hybrid is equipped with a supercharger. For a more direct response, even at low revs and road speeds. This is particularly useful when driving in urban traffic. The supercharger has a low-temperature water cooling system for cooling the charge air.

We have always gone our own way. This is the hallmark of our independent spirit. Only thus can we continue to meet our high performance standards. And yours. For the Cayenne S Hybrid we chose a highly sophisticated technical concept. Thanks to Intelligent Performance, it perfectly embodies the key principle of an alternative drive: efficiency.

The parallel full hybrid drive on the Cayenne S Hybrid features a 3.0-liter V6 supercharged engine and an electric machine (motor/generator) that provides additional power on demand. It offers levels of acceleration that are comparable with a V8 unit, but with a reduction, when compared to the Cayenne S fuel consumption.

The engine delivers 333 hp, while the electric machine generates 47 hp. Working in tandem, they

produce a total output of 380 hp.

With a top speed of 152 mph, acceleration from 0 to 60 mph takes 6.1 seconds. Maximum torque is 428 lb.-ft.

On the parallel full hybrid system, the electric machine and a decoupler are integrated directly into the drivetrain between the combustion engine and the eight-speed Tiptronic S. The decoupler ensures positive engagement with the combustion engine, thereby offering several benefits – both for the driver and the environment.

Under moderate acceleration, the electric machine can power the vehicle independently. In order to

drive quietly through residential areas, for example. The generator can also be used to recuperate energy during braking, i.e. for charging the battery.

In addition, the electric machine can be used to boost performance – for faster acceleration.

Other energy-saving features include the car’s ability to glide along, even when the engine is turned off. The hybrid system therefore also brings significant advantages when not driving in city traffic, as the vehicle can simply ‘coast’ along many stretches of road without any power at all. Together with the Auto Start Stop function, the parallel full hybrid system offers exceptional levels of performance and efficiency.

The ‘hybrid’ designation and each front fender alludes to the innovative drive concept within.

Inside the car, the TFT color display in the instrument cluster provides information on the current energy flow. Further driving data is displayed via the optional Porsche Communication Management (PCM). But the greatest benefit of all: the Cayenne S Hybrid is a Porsche. And it drives like one too.
