Repair and Diagnosis: Description and Operation

Foreword

The Cayenne opens up a new chapter in its success story. Four years after the market launch of the model, Dr. Ing. h.c. F. Porsche AG presents the second generation of its sporty off-road vehicle.

The new 2nd generation Cayenne, Cayenne S and Cayenne Turbo models have new, higher-performance engines with direct fuel injection (DFI). The basic version of the sporty off-road vehicle has an increased power output of 40 HP (29 kW). The Cayenne is now driven by a 290 HP (213 kW) six-cylinder engine. Displacement has been increased from 3.2 liters to 3.6 liters and the torque was increased from 230 ftlb. (310 Nm) to 285 ftlb. (385 Nm).







Thanks to the new direct fuel injection system (DFI) and the introduction of VarioCam Plus valve control, the Cayenne S, which features a V8 naturally aspirated engine with an increased displacement of 4.8 liters, achieves a torque of 370 ftlb. (500 Nm) compared to the previous torque of 311 ftlb. (420 Nm). It now has an engine power of 385 HP (283 kW) - an increase of 45 HP (33 kW) compared to the previous model.

The engine power of the new top model Cayenne Turbo is 50 HP (37 kW) higher than the previous model. The new eight-cylinder engine, which is driven by two turbochargers, has a power output of 500 HP (368 kW) and a torque of 518 ftlb. (700 Nm) compared to the max. torque of 459 ftlb. (620 Nm) on the previous model.

TECHNICAL MANUAL: Technical data is intended to provide an overview only. As it is subject to change during the course of the model year, refer to the Workshop Data for up-to-date technical data.

The proven Porsche Traction Management system (PTM), which distributes 62 percent of the engine power to the rear wheels and 38 percent to the front wheels in basic mode, ensures ideal power transmission. A multiple disc clutch allows up to 100 % of the drive torque to be directed to the front or rear as required.

The active chassis control system Porsche Active Suspension Management (PASM) with air suspension comes as standard on the Cayenne Turbo. This type of chassis can now be optimised using the new roll stabilization system Porsche Dynamic Chassis Control (PDCC), which Porsche has introduced for the first time. Continuous roll stabilization reduces the vehicle's lateral inclination during cornering and balances the vehicle in practically all driving situations.

All Cayenne models have Porsche Stability Management (PSM) with brake assist, enhanced Trailer Stability Management and off-road ABS. These functions ensure a faster braking response, significantly reduced instability for vehicles with a trailer, for example, and optimized braking effect on loose surfaces.

Bi-Xenon headlights (which come as standard on the Cayenne Turbo) guarantee even more active safety. The headlights not only have a static cornering light, but now also feature for the first time a dynamic cornering light, which is activated once the vehicle is travelling at more than 2 mph (3 km/h). This light is available as an option on the Cayenne and Cayenne S.
