The Porsche V6
|
CayenneIn its engine output and performance, the Porsche Cayenne, just like its sister models, offers a supreme standard: Maximum output of the six-cylinder power unit at 6000 rpm is 184 kW (250 bhp), maximum torque is 310 Newton-metres (228 lb-ft) from 2500 - 5.500 rpm.
Six-Speed Gearbox with Innovative Porsche Drive-Off Assistant The power of the six-cylinder engine featured in the Cayenne is transmitted in standard trim by a newly developed six-speed manual gearbox. This gearbox is combined with an innovative assistance system helping the driver set off on gradients: The Porsche Drive-Off Assistant secures the vehicle by automatically intervening in the brakes. Then, once the driver engages the clutch, the system takes back the brakes and allows the driver to set off smoothly in his Cayenne. The Cayenne is available as an option with Porsche's six-speed Tiptronic S transmission. Applying Porsche's usual control philosophy, this specific automatic transmission allows the driver to shift gears manually by means of paddles in the steering wheel. Another option is to shift gears by briefly flicking the selector lever forwards or backwards, a function particularly convenient for shifting gears on rough terrain. And for the first time the "Shift on the Move" function allows the driver to activate the reduction gearbox at low speeds (below 15 km/h) or deactivate it again (up to 30 km/h). Cutting-Edge Four-Wheel Drive The Cayenne comes with a number of highlights in technology providing the ideal synthesis of supreme onroad and excellent offroad driving characteristics, features which indeed made their world debut in Porsche SUVs. One example is Porsche's intelligent Traction Management (PTM) providing a 62:38 split of engine power between the front and rear wheels in the basic mode. Then, via a multiple-plate clutch, up to 100 per cent of the drive forces may be fed to the front or rear wheels depending on requirements. In this process PTM does not just respond as a function of traction (or the lack thereof). Instead, sensors also measure the speed of the vehicle, its lateral acceleration, the steering angle and position of the gas pedal, providing better control when driving to the limit. A further feature standard in the Cayenne is Porsche Stability Management (PSM), constantly interacting with PTM, but only intervening when the vehicle is driven to the absolute limit under extreme conditions. PSM also comes in very handy whenever a trailer is about to swerve, applying the brakes specifically on individual wheel in order to maintain the necessary stability. The Cayenne's outstanding performance on the road is perfectly supplemented by equally superior offroad driving qualities: On rough terrain PTM is able to activate the reduction gear integrated in the power divider as well as a 100 per cent front-to-rear wheel lock should individual wheels lose their traction. Chassis and Suspension for the Road and Rough Terrain
Superior Active and Passive Safety The Cayenne offers superior active and passive safety, again in typical Porsche style. Acting as the ideal partner for the drivetrain, chassis and suspension, 17-inch brakes front and rear with inner-vented 330-millimetre (13.00") brake discs ensure powerful and smooth application of the brakes without fading. The discs come with six-piston monobloc aluminium fixed callipers at the front and four-piston aluminium fixed callipers at the rear. Whether in a head-on, a glancing, side-on or rear-end collision, whether in a roll-over or hitting a pole, the Cayenne fulfils all legal requirements the world over. The longitudinal and transverse structure of the front end, for example, ensures intelligent distribution of impact forces in a collision. Deformation energy is taken up by three load levels above one another, forces being split up among the stiff chassis legs on floor level, the sill and tunnel area, and the door structure. Ultra-modern multiphase steel offering the highest strength standard of and stability has been used furthermore on the seat crossbars at the bottom and the rear floor crossbar. The B-pillars, finally, are made of TRIP steel on the inside, as are the reinforcements on the A- and B-pillars serving to enhance safety in a rollover. Combination of Thorax and Curtain Airbags The concept of passive safety continues consistently throughout the interior of the Cayenne. The full-size airbags for the driver and front passenger are activated in each case by a two-stage gas generator reducing loads acting on the occupants in the event of a collision. Two sensors fitted in the bumper area serve to detect collisions from the front. The side impact system is made up of a thorax airbag integrated at the side in each front seat back-rest and a curtain airbag fitted in the roof frame. Used by Porsche for the first time, the curtain airbag moves down from the roof when inflated, covering the side window area and protecting occupants both front and rear. A further feature is the fitment of three-point seat belts on all five seats, all of which - with the exception of the centre seat at the rear - come with a belt latch tensioner. The front seats also have belt force limiters in order to further reduce any loads acting on the occupants. Porsche All the Way also Inside the Cayenne Inside the Cayenne you will also enjoy that typical Porsche style borne out by features as unmistakable as the ignition lock to the left of the steering wheel, the circular instruments with the multifunction display right in the middle, or the three-spoke steering wheel with Porsche's coat of arms in colour. Other standard features are the alarm system, central locking with remote control, an on-board computer, tinted heat-insulating glass, air conditioning, electric window lifts, and electrically adjustable front seats. It almost goes without saying that the seats - and this includes the seats at the rear - are finished in leather. The steering wheel rim, door closing handles, grab handles in the centre console, and the gearshift lever also come in leather. And last but certainly not least, a CD-radio with a double-tuner even able to play MP3 files and 12 loud-speakers is also standard. And last but not least, the new electronic logbook comes as special equipment, as with both of Porsche's sports cars and on all other Cayenne models. Convincing Transport Concept The Cayenne's luggage compartment fully equipped as standard with a partition net and roll cover offers a capacity of 540 litres. The rear-seat backrest and seat bottoms tilt forward additionally either completely or with a 40:60 or 60:40 split, increasing luggage compartment capacity to a maximum of 1770 litres. A further advantage is the low loading sill for very convenient loading and unloading, an electrical closing unit helping to close the tailgate. The rear window opens upwards to pro-vide yet a further option allowing the driver and his passengers to load small items without even opening the tailgate. Wintersport enthusiasts, in turn, are able to use the ski-bag for through-loading their skis, and sports-people with really big luggage such as a glider or a sports boat can have their Cayenne fitted additionally with a trailer towing bar for loads of up to 3.5 tonnes (braked). The customer has the choice of three different trailer systems, including a fixed-position trailer bar and a manually removable version. The third trailer towing system, by contrast, offers a far higher standard of comfort and convenience, with a towing bar folding down electrically at the touch of a button (not available in the US market). To prevent unwanted operation of this towing mechanism the lowering/lifting process is activated by a toggle switch fitted on the right-hand side of the luggage compartment. And again in the interest of extra safety, the towing bar can only be lowered or lifted with the vehicle at a standstill. To facilitate the subsequent process of fastening a trailer, all Cayennes are come as an option with a back-up camera hidden behind the trim strip beneath the rear window. This camera moves out automatically as soon as the driver shifts to reverse, providing an exact overview on the PCM screen in manoeuvres. Optional PCM with Offroad Navigation The Cayenne comes as an option with Porsche Communication Management (PCM) compri-sing a double-tuner, CD-player, dynamic route navigation based on DVD technology, an on-board computer and a GSM dual-band telephone. As a further option the PCM navigation system may be supplemented by a special offroad navigation unit available from Porsche for the first time, offering additional altitude information, presenting the position of the wheels, and even serving as a compass. Yet a further feature of offroad navigation is the choice given to the user to enter his destination on a map by way of a hairpin finder, and to use the back-tracking function memorising the route covered and guiding the driver back on the same route he took to his initial destination.

Indeed, the torque curve alone is an
outstanding symbol of muscular performance, exceeding the mark of 300
Newtonmetres (221 lb-ft) just above 2000 rpm and remaining above this limit
all the way to 5000 rpm. The performance this means in practice speaks for
itself, the Porsche Cayenne accelerating from 0 - 100 km/h in 9.1 seconds,
then continuing all the way to its top speed of 214 km/h or 133 mph. With
the driver exercising the appropriate style of motoring, the Cayenne is a
very fuel-efficient vehicle, returning superior fuel economy of less than
12 litres/100 km or more than 23.5 mpg Imp on the road. According to the
EU standard, the Cayenne consumes 10.6 litres of fuel for 100 kilometres
outside of town (26.6 mpg Imp), composite fuel consumption under the EU standard
also including urban motoring amounting to 13.2 litres/100 km (21.4 mpg Imp).
The chassis and suspension of the Cayenne
are configured and designed for supreme driving dynamics combined with
outstanding safety and offroad qualities. The front axle is a large-dimensioned
double track control arm configuration resting in a subframe held elastically
by large-volume rubber mounts. With the track control arms being far apart,
forces in the suspension are kept to a minimum. The rear axle is an elaborate
multi-arm configuration able to handle both traction forces and any loads
the Cayenne may be carrying with absolute ease. Long spring travel for offroad
motoring is particularly helpful. With ground clearance of 217 millimetres
or 8.54", the embankment angle is 29.1° at the front and 25.7°
at the rear. The ramp angle is 20.4°, and the vehicle is able to cross
bodies of water up to 50 centimetres or almost 20" deep. As an option the
Cayenne is available with the air suspension of the Cayenne Turbo as well
as the variable Porsche Active Suspension Management (PASM) damping system.
