Plengs
Standard equipment includes the new V6 engine, a six-speed Tiptronic S transmission and such Porsche technologies as Porsche Stability Management and Porsche Traction Management, plus much more, including leather seating surfaces for five people and side-curtain airbags.
Base prices are $42,900 in the United States and $60,850 in Canadian dollars.
The Porsche Cayenne option list includes the Porsche Communication Management system that features a navigation system and Porsche's new Advanced Offroad Technology Package, which also becomes available on the Porsche Cayenne S and Cayenne Turbo models.
A true SUV, but also a true Porsche
Like the Porsche Cayenne S and Cayenne Turbo models, the 2004 Porsche Cayenne has the architecture of an SUV, but the same soul that is part of every Porsche. Thus Porsche Traction Management can claw its way up a rocky trail, but also provides sure-footed traction and control for high-speed lane changes.
Except for its engine and a few other components, the 2004 Porsche Cayenne is identical in design and construction to the Cayenne S and Cayenne Turbo. The only visual clues to differentiate the new model from its siblings are its black-colored brake calipers, its standard, 10-spoke, light-alloy, 17-inch wheels, and a "Cayenne" script on its rear hatch without an "S" or "Turbo" suffix.
V6 provides 247 horsepower (SAE) with a broad peak power plateau
The 2004 Porsche Cayenne features a 3.2-liter V6 engine tuned by Porsche engineers to produce 247 horsepower (SAE) at 6,000 rpm and 228 pound-feet of torque, with that peak torque figure achieved all the way from 2,500 rpm to 5,500 rpm.
Performance figures are impressive, in both speed and distance
Working though the Tiptronic S transmission and Porsche's four-wheel-drive systems, the V6 propels the 2004 Porsche Cayenne from a standing start to 62 miles per hour (100 km/h) in 9.7 seconds. The 2004 Porsche Cayenne's top speed in track testing is 133 mph (214 km/h).
Other performance figures include 0-100 mph (160 km/h) in 25.0 seconds and a standing-start, one-kilometer (.62-mile) sprint in 30.8 seconds. The V6's performance includes 15 city and 19 highway fuel economy figures (15.6 liters per 100 km city and 12.2 per 100 km highway in Canada). The 2004 Porsche Cayenne has a 26.4 gallon (100 liter) fuel tank.
With its 22.7-gallon fuel tank, the 2004 Porsche Cayenne has a range that exceeds 430 miles.
The first V6 in any Porsche model
While the engine block is sourced from Volkswagen, which is Porsche's partner in the construction of the Cayenne's unit-body chassis, the 15-degree, 3.2-liter V6 engine has been extensively reworked by Porsche engineers. They designed an entirely new intake system for the engine, with two overhead camshafts and continuously variable intake valve timing. They also reworked the exhaust system to provide the sound that immediately identifies the Cayenne as a true Porsche.
Modifications prepare V6 for extreme conditions
Porsche engineers also designed modifications to the engine for towing, including the engine cooling system. To verify the Porsche Cayenne's ability in extreme conditions, testing was done while pulling the maximum load (7,716 pounds or 3500 kg) in temperatures as high as 122 degrees Fahrenheit (50 degrees Celsius).
The powertrain and its belt-drive system also were designed and developed for the challenges Porsche Cayenne owners may face in extreme off-pavement driving. Thus the V6 operates smoothly while the Porsche Cayenne is driven through water as deep as 20 inches (500 mm) or at angles - uphill, downhill or side hill - as steep as 45 degrees.
Six-speed Tiptronic S transmission
Just like the Cayenne Turbo and Cayenne S, the 2004 Porsche Cayenne is equipped with a six-speed Tiptronic S transmission designed to provide an enhanced range of individual gear increments and to retain the driver's option to shift gears manually by tipping the selector lever on the center console or simply by using switches on the steering wheel that can be activated by the driver's thumbs.
The driver can press the upper portion of the thumb switch or tip the center console shift selector forward to advance the gears, or press the lower part of the thumb switch or tip the shift selector back to downshift.
Momentary manual operation, even in automatic mode
One major advantage of the Tiptronic S is that it provides the driver with the option of intervening while the transmission is in automatic mode. The driver can move the thumb switch on the steering wheel and shift gears manually even though the gearshift selector lever in the center console remains in the automatic position. In such a case, the manual mode is activated for at least eight seconds, and this period is extended when the car is in "overrun" - for example, on a downhill grade, to capitalize on engine braking - or when the driver downshifts before the entrance to a curve and the car is under lateral acceleration as it negotiates the turn.
When in such a situation, the letter "M" appears in the right-hand instrument dial and the specific gear engaged also is displayed. At the same time, the transmission retains its kick down function so the driver can downshift again as needed. The transmission can downshift by as many as three gears when the driver steps hard and quickly on the gas pedal.
Driver's right foot is in control
In automatic mode, Tiptronic S adjusts to various shift control maps based on the driver's style of driving and the route.
The range of shift points extends from a particularly economic mode activated whenever the driver prefers a calmer and more reserved style of driving (with the gears shifting up at an earlier point and engine speeds being reduced accordingly) all the way to a very dynamic, active mode (with the gears remaining in mesh for as long as possible when accelerating, using the engine's free-revving driving characteristics). The crucial factor in all cases is the driver's foot on the accelerator: Moving the gas pedal quickly and dynamically, accelerating frequently with full power, the gearshift points change accordingly, switching if necessary to the most dynamic variant and vice versa.
Over and above its ability to recognize the driver's style, Porsche Tiptronic S also features:
- A warm-up program that prevents the transmission from shifting up too soon, thus increasing the temperature of the catalytic converter as quickly as possible while allowing the engine to warm up smoothly and without any strain;
- An active gearshift that immediately moves the shift points to the most sporting and dynamic program whenever the driver presses the gas pedal quickly and dynamically;
- Suppression of upward gearshift in overrun when the driver's foot suddenly lifts off the accelerator, for example, before entering a bend;
- Downshifting to the next lower gear to optimize engine braking when the brakes are applied;
- Increment upshift that delays shifting into a higher gear after an active downshift;
- Retention of gears in a bend to prevent upshift; and
- Hill recognition that retains lower gears as long as possible in uphill or downhill gradients.
To reduce the possibility of an improper shift when the Porsche Cayenne SUV is traversing rough terrain, the steering wheel switches are deactivated when the reduction gearbox is engaged. In this case, the driver can shift manually only by moving the shift lever on the center console. But the driver may not have to shift manually because Tiptronic uses gearshift control maps to ensure optimum power in rough terrain.
Another Tiptronic S feature in the Porsche Cayenne is a hill-holder function that prevents the car from rolling backward when setting off in a forward gear, even on a steep grade.
Porsche's proud 4wd heritage
While best known for its rear-wheel-drive sports cars and for its success in major international motorsports competition, Porsche's expertise in four-wheel-drive dates back more than 100 years to the Löhner Porsche, one of Prof. Ferdinand Porsche's first race and rally winning vehicles. (Prof. Porsche is Dr. Ferdinand "Ferry" Porsche's father.) Porsche engineers continued to work on all-wheel drivetrain technology throughout the years that followed. Even NASA called on Porsche's all-wheel-drive expertise to help develop the lunar rover.
Nearly a quarter of a century ago, Porsche's 959 supercar won the grueling Paris-Dakar marathon rally and the car's all-wheel drive technology led to the development of the 911 Carrera 4 and the latest generation 911 Turbo.
The Cayenne, Cayenne S and Cayenne Turbo take Porsche's four-wheel-drive expertise to new venues and have proven their capabilities in off-pavement expeditions around the world.
On the fast track
The Porsche Cayenne is the sport utility, and it lives up to its name. Taken from the very hottest of red peppers, the Cayenne name stands for zestful spiciness that includes 0 to 62 mph sprint times of as little as 5.6 seconds for the 450-horsepower Porsche Cayenne Turbo, which has posted among the fastest laps ever by any production vehicle around Germany's famed Nürburgring.
With four doors, luxuriously comfortable seating for five, room for the gear a family needs to enjoy an active lifestyle, and a towing capacity of more than 7,700 pounds (3,500 kg.), the Cayenne is the first Porsche to provide both sport and true utility.
Porsche's off-pavement expectations are high
The 2004 Porsche Cayenne had to satisfy not only Porsche's extreme high performance and quality standards, but it had to meet the utility and reliability expectations only Porsche engineers demand from an SUV.
Thus all Porsche Cayenne models are equipped with Porsche Traction Management (PTM), a permanent four-wheel drive system, and Porsche Stability Management (PSM).
Sports car feel
PTM feeds the engine's power through a multiple-plate clutch operated by an electric motor. In normal driving, PTM feeds 62 percent of the engine power to the rear wheels and 38 percent to the front wheels, achieving a feel for the driver that is similar to Porsche's rear-engined sports cars.
However, whenever necessary, PTM can direct up to 100 percent of the engine's torque either to the front or the rear wheels. The map-controlled longitudinal differential lock and a locking rear axle differential, available as an option, not only respond to any lack of traction on the front or rear wheels, but incorporate sensors measuring vehicle speed, lateral acceleration, the steering angle, and gas pedal operation. PTM calculates the optimum locking action on both axles and spreads drive forces as needed to the front and rear wheels.
Therefore, PTM might be compared with a forward-looking, anticipative active electronic control system providing exactly the right balance for superior driving stability and supreme safety when changing lanes both at high speeds or when driving at a moderate pace on ice and snow.
When driven in light terrain, the Porsche Cayenne can handle all traction requirements through its intelligent four-wheel drive. However, when the going gets tough, PTM interacts with the reduced-ratio off-pavement gear; as soon as the driver activates the low-range mode, PTM and PSM adjust ABS (anti-lock brake system), ABD (automatic brake differential) and differential control settings to special off-pavement calibrations.
Should the terrain become so tough that individual wheels might lose contact with the surface, the four-wheel drive system is linked by rigid, firm connections to keep the driver on the move. All the driver has to do is flip the off-pavement switch located on the interior center console a second time to obtain a 100 percent front-to-rear wheel lock through the locking center differential.
Some of the particular benefits PTM provides are:
- Excellent driving stability and traction in all situations, regardless of surface friction,
- better steering and control by opening the longitudinal differential lock in order to avoid any understeer,
- enhanced vehicle control when driving to the limit, due to the longitudinal or center differential lock,
- improved directional stability and tracking control by appropriate activation of the longitudinal differential lock, and
- improved traction by increasing the degree of locking action before the wheels start to spin.
PSM intervenes when the vehicle is driven to the limit of adhesion and helps to stabilize the Cayenne in oversteer or understeer conditions to keep it headed in the direction the driver intends. PSM maintains a constant dialogue with PTM but only intervenes when the vehicle reaches its physical limit.
Coordinating essential systems such as the ABS, the automatic slip regulation (ASR) system, and the automatic brake differential (ABD), PSM is immediately available whenever the Porsche Cayenne enters critical over- or understeer conditions, "telling" PTM to open the differential locks in order to re-stabilize the car by applying the brakes specifically on individual wheels. Should that not be sufficient, PSM intervention includes engine management and automatically can adjust the engine's ignition and throttle to help stabilize the vehicle.
Suspension provides dynamic handling
The Porsche Cayenne's suspension provides the secure foundation for exceptional driving dynamics. It combines optimum safety, motoring comfort and off-pavement driving capabilities.
The front axle is an extra-large double track control arm configuration mounted on its own subframe. The large distance between the individual track control arms keeps forces acting on the suspension to a minimum, ensuring precise wheel guidance for agility and minimizing the influence of any adverse forces. Incorporating extra-large rubber mounts, the elastic subframe bearings keep road noise transfer to a minimum.
Made of high-strength steel, the subframe design has an arch-shaped crossbar and inclined ramps at the front that give the Porsche Cayenne ample ground clearance, 8.54 inches (217 mm) with the standard suspension.
Sports car-style steering
The variable-ratio steering gear and the differential are well protected on top of the subframe to help ensure robust off-pavement driving qualities. Like all Porsches, the Cayenne has hydraulic power-assisted rack-and-pinion steering as a standard feature. The steering ratio is 16.7:1, taking just 2.65 turns of the wheel from lock to lock, which is comparable to a sports car.
The Porsche Cayenne's turning radius is 39 feet (11.9 meters).
Rear axle designed for Cayenne's capabilities
The rear axle is a Porsche development. The rear axle configuration is an elaborate multi-arm concept easily able to handle both high traction forces and the Porsche Cayenne's high service load capabilities. In the interest of extra comfort and noise reduction, the rear axle is also mounted on a subframe resting on extra-large, hydraulically dampened rubber bearings. This subframe also is made of high-strength steel for optimal weight and maximum structure stiffness. The lower track control arm and the tie-rod are made of steel plate to ensure robust strength even on the roughest surfaces. The upper track control arm assembly, which is well protected within the vehicle, is made of extra-light forged aluminum components.
Through its particular configuration, the axle kinematics reduce undesired squat and dive when accelerating and braking, keeping the Porsche Cayenne almost entirely level on the road at all times. The rear axle configuration and the rear toe-in control stabilize the vehicle's driving behavior particularly in curves and under load change.
A special feature of the axle concept is the extra-long spring travel for off-pavement purposes.
Steel springs on Porsche Cayenne
With the steel spring suspension on the 2004 Porsche Cayenne, the front springs compress 4.09 inches and expand 4.57 inches (104 and 116 mm, respectively) while the rear spring travel is 5.31 inches (135 mm) compressed and 3.86 inches (98 mm) expanded.
With ground clearance of 8.54 inches (217 mm), the maximum embankment (approach) angle is 29.1 degrees in front and 25.7 degrees (departure) at the rear. The ramp angle (break over) is 20.4 degrees.
Air suspension available
For those needing more ground clearance, an optional air suspension is available. With the air suspension, which is standard equipment on the Porsche Cayenne Turbo and available as an option on the Cayenne and Cayenne S, the front springs compress 4.02 inches and expand 4.65 inches (102 and 118 mm, respectively). The rear springs compress 4.88 inches and expand 4.92 inches (124 and 125 mm).
Air suspension not only guarantees extra ground clearance on rough terrain, its self-leveling feature provides a consistent vehicle position regardless of the load.
The system also ensures maximum driving pleasure and active safety by automatically lowering the Porsche Cayenne relative to increasing road speed.
Incorporating six different ride height levels, the air suspension adjusts over a range of 4.56 inches (116 mm).
In normal mode, ground clearance is 8.54 inches (217 mm) according to the DIN unladen standard.
- In load trim, the Porsche Cayenne moves down 2.36 inches (60 mm) from its standard position to a loading level of 6.18 inches (157 mm). This level is only available when the vehicle is not moving and facilitates loading and unloading. As the driver begins to drive the vehicle, the system automatically returns to its normal level.
- In low-level mode, the Porsche Cayenne moves down 1.06 inches (27 mm) inches below its standard height and is comparable to a vehicle with a sports suspension. In practice this means the suspension is firmer and air resistance is lower, making the Cayenne even more stable and dynamic at high speeds. The suspension level automatically lowers from a higher position to the low high-speed setting at a road speed of 78 mph (125 km/h).
- At speeds exceeding 130 mph (210 km/h), the Porsche Cayenne automatically moves down to its extra-low ride level, which is 0.43 inches (11 mm) below the "regular" low setting.
- When driving off-pavement, the Porsche Cayenne can be set to the higher off-pavement level up to 1.02 inches (26 mm) over the standard ride height to negotiate difficult terrain. However, this high level is only available at speeds up to 50 mph (80 km/h).
- The special off-pavement level is for the most extreme driving conditions, raising the Porsche Cayenne another 1.18 inches (30 mm) to a ground clearance of 10.75 inches (273 mm). This extra-high level is only available at speeds of up to 19 mph (30 km/h).
Porsche offers air suspension in combination with Porsche Active Suspension Management (PASM), a new variable shock absorber damping system. Operated electronically, PASM adjusts damper forces infinitely as a function of surface conditions and the driver's driving style.
A typical example of PASM intervention occurs during powerful application of the gas and/or brake pedal or when driving on particularly rough terrain. PASM serves to steady any body sway and dive motions by monitoring body movement through five accelerometers. As soon as the motion of the Porsche Cayenne's body exceeds a certain limit depending on specific driving conditions, PASM intervenes and stabilizes the vehicle by acting on the individual dampers.
PASM also gives the Porsche Cayenne driver the opportunity to choose among three damper settings while driving - Comfort, Normal or Sports.
Consistently operating in the background, PASM always maintains its active control function, comparing the operator's driving style with the program currently in use. Whenever the driver has chosen a particularly comfortable damper setting but is driving in a more sporting or dynamic style, the system automatically switches over to the sports mode and makes the dampers firmer.
The Porsche Cayenne's outstanding road performance does not come at the expense of its off-pavement capabilities. Due to its intelligent four-wheel drive, the Porsche Cayenne is able to handle minor off-pavement conditions without requiring modification of the traction systems.
When the going gets tough...
When driven on rough terrain, the Porsche Cayenne uses the Porsche Traction Management system integrated as a standard feature in the power divider. This reduction gearbox comes with a 2.7:1 gear ratio for even the most extreme off-pavement driving maneuvers. By activating the low range mode by way of a toggle switch on the Cayenne's center console while the vehicle is stationary and in neutral, several control systems are automatically prepared for off-pavement conditions. PTM switches to the appropriate gear ratio for off-pavement driving and activates a special off-pavement control map for the differential locks. PSM switches on the traction-oriented off-pavement ABS and ABD system, and the optional air suspension automatically changes to the off-pavement ride level. Porsche is the first car manufacturer to offer this combination of systems controlled by a central off-pavement switch, thus reducing the risk of control errors when driving on rough terrain.
The Porsche Cayenne's standard off-pavement driving characteristics can be enhanced to a higher level. In the event individual wheels lose contact in demanding terrain, a direct and rigid connection of the four-wheel drive system provides mobility.
Operating the off-pavement switch a second time activates the 100 percent front-to-rear differential lock, and the optional standard air suspension provides additional assistance when climbing. In the special off-pavement mode, which provides 10.75 inches (273 mm) ride height, the inclination angle is up to 32.4 degrees at the front and 27.3 degrees at the rear, enabling the Porsche Cayenne to handle steep ramps.
Even extreme crests when driving from one gradient to another are not obstacles since the 24.7-degree ramp angle prevents the body, between the axles, from touching the ground prematurely.
All Porsche Cayenne models are equipped for water crossings thanks to the Cayenne's special sealing concept, a high-rise intake funnel, its elevated transmission purge opening, and full encapsulation of the side sills. The standard steel spring suspension on the Porsche Cayenne allows it to traverse water up to 19.7 inches (500 mm) in depth. The air suspension enables the Porsche Cayenne to handle water crossings up to 21.85 inches (555 mm) deep.
Advanced Offroad Technology Package available on all Cayenne models for 2004
With the introduction of the 2004 Porsche Cayenne, Porsche offers an Advanced Offroad Technology Package for the most extreme off-pavement conditions. This new system is available on the Porsche Cayenne S and Cayenne Turbo as well as on the Porsche Cayenne.
The package includes special side protection and a steel plate under floor panel around the radiator as well as a fully controllable (up to 100 percent) differential lock on the rear axle. To fully activate the lock, the driver operates the central off-pavement switch a third time. The fully controlled rear axle lock then ensures even better traction when setting off on slippery surfaces with varying frictional coefficients or when negotiating curves.
The package also uses anti-roll bars on the front and rear axle. These anti-roll bars have built in "claw clutches" that are hydraulically activated and deactivated by a switch in the center console. This allows increased front and rear axle articulation by 2.36 inches (60 mm), which improves ride comfort by minimizing body sway and enhancing off-pavement driving qualities and traction when negotiating rocks, tree trunks or bumps.
To ensure the Porsche Cayenne's sporting driving qualities on the road, the anti-roll bars can only be disconnected in the low range mode. As soon as the Cayenne, with its anti-roll bars disconnected, returns from rough terrain to the road, the anti-roll bars are automatically reconnected as a safety feature once the vehicle exceeds 31 mph (50 km/h), thus providing the type of stability required for on-pavement driving.
Large brake discs
To ensure maximum braking efficiency, Porsche engineers equip the Cayenne with 13-inch (330 mm) inner-vented front discs with six-piston aluminum monobloc calipers and 13-inch (330 mm) inner-vented rear discs with four-piston aluminum monobloc calipers with pad-wear sensors. Anti-lock braking technology is standard.
Because of the risk of contamination under off-pavement conditions, the Porsche Cayenne's brake discs are not cross-drilled. Porsche engineers found in their extensive testing that cross-drilled brakes can collect debris that can cause premature wear and even damage to the braking system.
The Cayenne brakes have passed Porsche's extreme fade test. This test involves 25 full-force braking applications from 90 percent of the vehicle's top speed down to 62 mph (100 km/h). This must be accomplished while maintaining a consistent deceleration of 0.8 g.
The Cayenne model range is the first for Porsche with a foot-operated parking brake. This allows room for a large storage compartment in the center console. The system, which also features a self-adjusting brake cable, allows drivers to safely and securely park a fully laden Porsche Cayenne on a 55 percent gradient.
Large wheels
The 2004 Porsche Cayenne rides on standard 17-inch light-alloy wheels that are 7.5 inches wide and on 235/65 tires. Optional equipment includes 18x8 wheels with 255/55 tires, 19x9 wheels with 275/45 tires and 20x9 wheels with 275/40 tires.
The Porsche Cayenne also may be fitted with an optional tire pressure monitoring system that consistently monitors pressure on all four wheels. A sensor on the valve measures tire pressure and temperature. Whenever pressure drops by 2.9 pounds-per-square-inch (psi) or 0.2 bar, the system shows the driver through the multifunction display on the instrument cluster what tire is involved and the pressure difference. If pressure drops 5.8 psi (0.4 bar), the system automatically gives a warning signal.
High-strength steel construction
Some 60 percent of the 2004 Porsche Cayenne's body is built from high-strength steel.
Porsche's know-how also includes special skills in material joining technology, and the Cayenne makes good use of multi-phase steel (dual-phase and TRIP steel grades) that offer enhanced strength and good molding qualities compared to conventional construction techniques. For example, the Porsche Cayenne's A and B pillars are reinforced with TRIP steel with multi-phase steel at the bottom of the seat crossbars and on the rear floor crossbars. The Porsche Cayenne also benefits from tailored blanks and tailor-made components similar to those developed for Porsche's sports cars, ensuring that all structures along the chassis legs and roof frame edges are both lightweight and extremely stable.
The front section of the Porsche Cayenne features a combination of longitudinal support and crossbars to ensure the intelligent and safe distribution of forces in the event of a collision. Deformation energy spreads over three load levels into the stiff longitudinal floor support, side sill, tunnel and door shaft areas, minimizing deformation of the passenger compartment. The passenger cell also is highly resistant and provides supreme protection. Finally, the structure of the side sills is supplemented by a high-strength tube element inside the sills to reduce side intrusion.
All Cayennes are equipped with front, side and curtain airbags.
Porsche Side Impact Protection includes head-curtain system
POSIP (POrsche Side Impact Protection) is standard on all Porsches and provides the driver and front passenger with a broader scope of protection than conventional side airbags.
Because of the size of its interior, the Porsche Cayenne has a special airbag system that includes front, side and head curtain airbags. For the Porsche Cayenne, the side airbags have been placed in the backrests of the front seats and the curtain airbags are fitted into the roof frame. While providing protection for the driver and front-seat passenger's heads, this separate airbag also helps protect passengers sitting in the rear seat in the event of a side impact. This system is designed to provide protection even when the vehicle strikes a narrow obstacle such as a pole or a tree.
All five seats in the Porsche Cayenne are equipped with three-point belts, and all four outboard belts have belt latch pretensioners. The front seats also have belt-force limiters.
Porsche-style interior
Porsche has gone to great lengths to ensure the 2004 Porsche Cayenne interior reflects the unmistakable quality of Porsche design. The interior is refined, functional and sophisticated, and includes all the style and characteristics typical of a Porsche.
Of course, the ignition lock is positioned to the left of the three-spoke steering wheel, inspired by Porsche's racing history.
The instrument panel features two large round dials with a central multi-functional display. The leather-wrapped, three-spoke multi-function steering wheel bears a multi-colored Porsche crest.
Other standard equipment on the 2004 Porsche Cayenne includes titanium-colored interior trim, on-board computer, alarm system, central locking with remote control, 12-way power-adjustable front seats, heat insulated and laminated privacy glass, air conditioning with manual controls and integrated charcoal canister and pollen filter, heated and retractable exterior mirrors, a digital radio with an in-dash CD player and 12 speakers and a refrigerated glove compartment.
Folding rear seat expands generous cargo capacity
The luggage space - fitted with a luggage net and boot cover - has a capacity of 19.07 cubic feet (540 liters) with the rear seat in its upright position.
However, the rear seat backrests can fold down with a 40/60 split, thus providing 62.51 cubic feet (1,770 liters) of rear cargo space.
Rear window opens for easy access
Loading and unloading are eased by the low loading sill height. However, it is not necessary to fully open the rear hatch when loading smaller objects. The Cayenne's rear window opens upward, which provides a second option for accessing the luggage compartment.
Long list of optional equipment
The options list includes metallic paint, a rear-mounted spare tire carrier; special "smooth leather" or "soft look" interiors; heated seats (front or all positions); sport seats; wood, aluminum or carbon fiber interior trim; a trailer hitch; tire pressure monitoring system; front and rear park assistant; four-zone air conditioning; an off-road design package; Bi-Xenon headlamps; and Porsche Communications Management system with navigation.
Porsche Communication Management provides much more than a navigation system
Porsche Communication Management (PCM) operates at the speed of light, and now it also works as well off-pavement as on.
Using Porsche's MOST (Media-Oriented Systems Transport) technology, PCM uses light wave conductors to exchange multi-media data in every Porsche model in which it is installed. The big advantage of this technology is that it exchanges data without any loss of quality and at extremely high speeds. Among other features, this assures high-quality audio transmission for radio, CD changer and amplifier units.
The customer decides on a specific level of PCM equipment when choosing a Porsche vehicle. For example, networking PCM with the instrument cluster via the CAN (Controller Area Network), the driver can view within the instrument cluster information such as a radio station, music titles, and navigation pictograms.
Featuring a double audio tuner, CD player, dynamic route navigation, and trip computer, optional PCM provides a user-friendly design that includes a color screen and 12-digit keyboard. In the Porsche Cayenne, that screen is 6.5-inches across and provides the clarity of a 16:9 aspect ratio. The keyboard can be used for entering information such as radio station frequencies.
In addition, buttons beneath the display provide direct access to the individual menus such as trip computer (Trip button) or the navigation system (Navi button). Two buttons providing direct access to the Set (Set button) and Return (button with a bent arrow), thus avoiding the need to "jump around" from one sub-menu to another and waste a lot of time in the process.
As well as interference-free radio reception, ensured by a modern double tuner consistently looking for the best frequency, the navigation module features the following outstanding highlights:
- Large choice of various navigation functions: Functions can also be presented on the map in the display, informing the driver of such facilities as restaurants, service stations or parking lots;
- On-demand road junction zoom: This function automatically enlarges road junctions in the active guidance mode, providing helpful support above all at dangerous points where a road junction is unclear.
- Map scroll: Benefiting from the wider range of map options, the user is able to shift the map display, scroll and position the map as required. This enhances navigation from the current location to the desired destination, checking out and memorizing a destination by means of a reticule display without having to enter the exact address.
- Tour planning: The tour planning function allows the user to enter and memorize routes with as many as eight destinations in a row. When setting out, the system will automatically guide the driver to the individual destinations on the way, in precisely the order recorded in advance. Further processing options on such extended routes are also possible, such as adding information, removing destinations, changing the order of destinations on the way or skipping a certain point.
- With the 2004 Porsche Cayenne, Porsche introduced a special off-pavement navigation unit that provides altitude, the position of the vehicle's wheels, and a compass. Drivers also can enter a destination through a special finder and use a new backtracking function that memorizes the route covered and then guides the driver back along the same route.
- Music played by the navigation CD ROM drive: Apart from the usual navigation function provided by a CD-ROM, the new PCM system also allows memory-based navigation. In this case, after the route is calculated, the driver can remove the navigation CD and insert an audio CD into the CD-ROM drive. Should it be necessary to reinsert the navigation CD, for example to calculate an all-new route, the system will automatically inform the driver by generating an optical and an acoustic signal.
