2007 Porsche Cayenne

With a striking new face that features a dramatic new headlight design and with a wide and muscular body accented by broad wheel arches, the 2008 Porsche Cayenne’s newly sculpted shape provides vivid visual testimony to the vehicle’s enhanced technical features. bThe 2008 model year marks the launch of the second generation of the Porsche SUV, and the new Cayennes back up their aggressive new design with larger and more powerful – but also more fuelefficient – engines.

As you would expect from Porsche, the new Cayenne not only looks more powerful, it is, with engines offering as much as 500 horsepower and new dynamic technologies that allow the Porsche of SUVs to perform more like a more nimble vehicle, yet still be capable of towing a trailer or challenging unpaved terrain and inclement weather.

Indeed, all three 2008 Porsche Cayenne models feature engines that for the first time boast direct fuel injection, a technology that enhances fuel efficiency as well as power production. For the 2008 Porsche Cayenne Turbo, that means a twin-turbocharged 4.8-liter V8 that pumps out an astounding 500 horsepower and 516 pound-feet of torque. Flowing through a six-speed Tiptronic S transmission, that power feeds all four wheels and propels the five-passenger sports machine from a standing start to 60 miles per hour (96 km/h) in just 4.9 seconds. Top speed on the test track has been recorded at 171 mph (275 km/h). And yet, the Cayenne Turbo qualifies as an LEVII (low-emission vehicle) and in preliminary fuel economy testing the Cayenne Turbo showed the benefits of the direct fuel injection technology with an improvement up to 11 percent in highway driving. The estimated EPA fuel economy values are 13 mpg for city driving and 20 mpg on the highway.

For the 2008 Porsche Cayenne S, the engine is a normally aspirated version of the 4.8-liter V8 that generates 385 horsepower and 369 lb-ft of torque. Equipped with the standard six-speed Tiptronic® S transmission, the Cayenne S can accelerate to 60 mph in 6.4 seconds and has reached 155 mph (250 km/h) in testing. The Cayenne S V8 even meets ULEV (ultra low-emission vehicle) status and according to preliminary testing data the estimated EPA fuel economy values for the new Cayenne S are 14 mpg in the city and 21 on the highway. That is an improvement of 3 mpg or around 15 percent for highway fuel economy.

The 2008 Porsche Cayenne is powered by a 3.6-liter V6 that pumps out 290 horsepower and 283 lb-ft of torque. With the manual gearbox, the Cayenne reaches 60 mph in 7.5 seconds and has reached 141 mph (227 km/h) in testing. The new Cayenne gains LEV2 emission status and preliminary fuel economy testing showed estimated EPA fuel economy figures of 18 mpg in the city and 22 on the highway. That is a fuel economy improvement of 3 mpg for city driving.

Direct fuel injection is only one of the new technologies featured on the 2008 Porsche Cayenne, Cayenne S and Cayenne Turbo. For example, for the first time the Cayenne V8 engines also are equipped with Porsche VarioCam® Plus variable valve control.

The second generation SUVs can be equipped with Porsche Dynamic Chassis Control (PDCC) that includes active anti-roll bars that almost completely offset body roll in turns, improving handling, comfort and safety on road while also providing enhanced traction off pavement.

New as well are Dynamic Curve Lights (standard on the Cayenne Turbo and optional on the other models) to enhance the driver’s view at night on a curving roads.

Standard equipment on all versions of the 2008 Cayenne includes Porsche Stability Management (PSM®), now with new functions such as pre-loading of the braking system when needed, new Trailer Stability Control and off-road ABS.

For the first time, the Cayennes come with a rollover sensor able in an emergency to trigger both the belt latch tensioners and curtain airbags, thus helping to reduce the risk of injury for all occupants in a rollover. In conjunction with the Cayenne’s six standard airbags, this system gives Porsche’s sport utility a benchmark occupant safety and protection system.<

Other new features include a standard and push-button Sports mode for all Cayenne engines, a standard power rear lift gate, the availability of 21-inch wheels, a rail-mounted cargo management system and XM satellite radio.

This powerful entertainment and communications system is standard in the Cayenne Turbo and optional in the Cayenne and Cayenne S. Key features include a high-resolution color display with 16:9 aspect ratio, a highperformance MP3-compatible
CD radio with two-tuner frequency diversity, DVD-based satellite navigation and additional onboard computer functionality.

A dual-channel RDS tuner allows you to search for stations by format and store up to 40 presets. Radio station names and CD tracks are displayed on the PCM screen and inside the instrument panel’s center dial. The integrated CD drive is MP3-compatible.

Onboard computer.
The PCM computer supplies a wide range of information, including date, time, average fuel consumption, average speed, and time and distance traveled. It can also monitor the remaining range from the fuel on board, as well as the distance to destination and the estimated time of arrival.

Navigation system.
At the heart of PCM is a GPS navigation system. Selecting a destination is extremely simple, with a range of input options to
choose from. The system lets you enter a street address or intersection, select your destination from a list of menus, and display by a category. You may also simply point and click using the onscreen map.

Extended navigation module.
This optional addition to the PCM navigation system enables automatic navigation along a previously recorded route (reverse route navigation). It also facilitates compass and GPS-based navigation in regions not covered by your navigation DVD. When off-road, the current vehicle location is permanently displayed on the PCM terminal screen.

Electronic logbook.
This optional addition to PCM enables you to automatically record the mileage, route distance, date and time, as well as starting location and destination for every journey. Data can be downloaded from PCM and processed on a PC using software included with the package.

Telephone module.
Available as an option, this GSM telephone module has an 8-watt transmitter and convenient handsfree facility. An optional handset with keypad and display is also available. To assist in optimal reception, the telephone antenna is incorporated within the roof spoiler.

Porsche Rear Seat Entertainment
Available as a factory-fitted option from Porsche Exclusive or retrofit accessory from Porsche Tequipment, the new and substantially improved Porsche Rear Seat Entertainment System is comprised of two video displays, one media player, two wireless infrared headphones and one remote control. The media player is now incorporated into the front- passenger-seat video display. This leaves the middle seat free for passengers.

The system is compatible with all standard media formats (e.g., CD, DVD and MP3). A digital anti-shock memory ensures continuous, uninterrupted play. It is also possible to connect two separate and individually selectable AV sources, such as a game console or digital camera.

The system complies with the usual Porsche standards of safety and ergonomics, and blends harmoniously within the passenger compartment. The seven-inch swivel-mounted TFT (thin film transistor) displays are trimmed in matching interior leather and mounted on the frontseat backrests.

Bose Surround Sound System

Porsche drivers appreciate sound. The distinctive acoustics of the engine and exhaust are a major part of the Porsche driving experience. Now you can add an extra dimension with an optional Sound Package for the newCayenne and Cayenne S.

The Bose Surround Sound System provides the ultimate in digital incar audio. Standard equipment on the Cayenne Turbo, it is
compatible with both Porsche Communication Management (PCM) and the CDR-23 CD radio. The system is designed to blend CD and radio output with the unique acoustics of the Cayenne models. This is achieved by tailoring all system components to the generous interior and adjusting sound output using Bose Signal Processing (BSP).

Simply push a button and you’re immediately immersed in the lifelike audio of Bose Automotive Surround Sound. This proprietary technology uses additional audio channels at front and rear to create a rich and panoramic sound.

The digital amplifier supplies 250 watts of output through eight separate channels. A total of 13 loudspeakers in the dashboard, doors, luggage compartment and D-pillar, together with a 100-watt subwoofer in the spare wheel well, provide balanced audio output throughout the Cayenne interior. The Bose Nd bass speakers are neatly integrated within the doors, thanks to their ultra-slim profile and lightweight design.

Special features include AudioPilot noise compensation technology, which uses a microphone in the cockpit to monitor ambient sound and provide real-time adjustment of all output. The results are greater clarity and more consistent sound, with no need for continuous manual adjustment.

Panoramic roof system

The power-operated panoramic roof system is available as an option on all new Cayenne models. Made from laminated safety glass, it has a total surface area of almost four times the slide and tilt moonroof. Even when closed, it provides a unique “open top” driving experience. The panoramic view can be enjoyed from all seat positions in every type of weather.

A key advantage of the panoramic roof system is its variability. The roof consists of three movable segments and one fixed segment. When the roof is opened, the forward segment is tilted upward to act as a wind deflector. With the aid of special flaps, it reduces turbulence and noise, even when the vehicle is traveling at higher speeds. The two middle segments can be opened separately to provide a stream of fresh air to the front or rear. To do this, one segment slides above or below the other. For the full opentop driving experience, both central segments can be fully retracted to the rear. It is also possible to tilt segment above the rear seats to provide additional ventilation. In all, there are 15 variations to choose from.

A power-operated sunscreen protects the interior against direct sunlight. The entire roof system is operated using a single illuminated rotary control located on the roof console. When the Cayenne is stationary, the roof can also be operated using the ignition key in the door lock. An anti-jam function is also included.

Inside

Anyone familiar with the layout of a Porsche interior will feel instantly at ease sliding behind the wheel of the new Cayenne. It’s only when you glance over your shoulder, at the spaciousness and utility afforded the four-door configuration, that Cayenne reveals itself to be unlike any Porsche you’ve ever experienced.

Directly before you is the signature Porsche instrument cluster, with its five round gauges presenting themselves with bold simplicity. Grip the steering wheel, and you form an immediate connection with your Cayenne.

In the new Cayenne and Cayenne S, the steering wheel comes with manual height and reach adjustment. In the new Cayenne Turbo, the steering wheel is electrically adjustable and automatically heated.

Standard on all Cayenne models is a three-spoke multifunction steering wheel. With the integrated function keys, you can control a range of systems with both hands on the wheel and your eyes attentive to the road ahead.

All three models come with leather upholstery on the seats, steering wheel, gear lever/selector, door handles, center-console grab handles and door-panel armrests. On the new Cayenne Turbo, the leather extends to the dashboard, center console, including armrest, door panels and steering-wheel airbag module.

Instrument

The elegant cluster of five round instruments is familiar to every Porsche driver.

To the left and right of the large central dial are the analog tachometer and speedometer. Your speed is also displayed in digital form, in the multipurpose display in the central dial. This displays other key information such as current gear selection (Tiptronic S), Sport status when Sport mode is selected, Tire Pressure Monitoring System (TPMS), system display in PTM Off-road mode, and onboard diagnostics messages. It can also be used to configure and view information from the onboard computer.

The Cayenne Turbo has a five-inch color display as standard. Its generous size and high resolution enable easy legibility at all times.

The Cayenne and Cayenne S are both equipped with a three-inch dot-matrix multipurpose display. This is augmented by additional digital fields for the clock and odometer in the tachometer and speedometer dials, respectively.

The far-left dial on all Cayenne models contains the oil temperature gauge. The far-right dial displays the turboboost pressure (Cayenne Turbo) or battery voltage (Cayenne andCayenne S).

Seats

Both the new Cayenne and Cayenne S come with 12-way electrically adjustable front seats as standard. As well as fore/aft, height, backrest and seat adjustment, both front seats are equipped with lumbar supports featuring electrically adjustable height and depth.

The Cayenne Turbo has a special Comfort Seat Package (optional on the Cayenne and Cayenne S) featuring 12-way electrical adjustment and an enhanced memory function for up to three sets of occupant preferences.

The driver-side memory storesseat, exterior mirrors, steering wheeland belt-height positions. On the passenger side, up to three seat positions can be saved and retrieved as required.

Available as an option on the Cayenne and now standard on the Cayenne S is the Driver Memory Package. This provides a memory function for the driver’s seat and exterior mirrors.

All seats are ergonomically designed for the optimal balance of comfort and feedback from the road. In addition, the side bolsters provide excellent cornering support.

The comprehensive range of adjustment options makes it easy to find the ideal driving position, regardless of physical build. For added comfort, both front seats have adjustable head restraints.

Technology

As much as 500 horsepower verifies aggressive styling
The 2008 model year marks the launch of the second generation of the Cayenne®, the Porsche of SUVs, and the new Cayenne, Cayenne S and Cayenne Turbo back up their aggressive new design with larger and more powerful – but also more fuel-efficient – engines.

With a striking new face that features a dramatic new headlight design and with a wide and muscular new body accented by broad wheel arches, the 2008 Porsche Cayenne’s newly sculpted sheetmetal provides vivid visual testimony to the vehicle’s enhanced technical features.

As you would expect from Porsche, the new Cayenne not only looks more powerful, it is, with engines offering as much as 500 horsepower, and with new dynamic technologies that allow the Porsche of SUVs to perform more like a nimble sports car, yet be fully capable of towing a trailer or blazing along unpaved terrain and through inclement weather.

Direct Fuel Injection
All three 2008 Porsche Cayenne models feature engines that for the first time boast direct fuel injection, a technology that enhances fuel efficiency as well as power production. For the 2008 Porsche Cayenne Turbo, that means a twin-turbocharged 4.8-liter V8 that pumps out an astounding 500 horsepower and 516 pound-feet of torque. Flowing through a six-speed Tiptronic S transmission, that power feeds all four wheels and propels the five-passenger sports machine from a standing start to 60 miles per hour (96 km/h) in just 4.9 seconds. Top speed on the test track has been recorded at 171 mph (275 km/h). And yet, the Cayenne Turbo qualifies as an LEVII (low-emission vehicle) and in preliminary fuel economy testing the Cayenne Turbo showed the benefits of the direct fuel injection technology with an improvement up to 11 percent in highway driving compared to the previous generation Cayenne Turbo. The estimated EPA fuel economy values are 13 mpg for city driving and 20
mpg on the highway.

The 2008 Porsche Cayenne S has a normally aspirated version of the 4.8-liter V8 that generates 385 horsepower and 369 lb-ft of torque. Equipped with the six-speed Tiptronic S transmission, the Cayenne S can accelerate to 60 mph in 6.4 seconds and has reached 155 mph (250 km/h) in testing. The Cayenne S V8 even meets ULEV (ultra low-emission vehicle) status and according to preliminary testing data the estimated EPA fuel economy values for the new Cayenne S are 14 mpg in the city and 21 on the highway. That is an improvement of 3 mpg or around 15 percent for highway fuel economy.

The 2008 Porsche Cayenne is powered by a 3.6-liter V6 that pumps out 290 horsepower and 283 lb-ft of torque. With the manual gearbox, the Cayenne reaches 60 mph in 7.5 seconds and has reached 141 mph (227 km/h) in testing. The new Cayenne gains LEVII emission status and preliminary fuel economy testing showed estimated EPA fuel economy figures of 18 mpg in the city and 22 on the highway. That is a fuel economy improvement of 3 mpg for city driving.

A long list of new technologies
Direct fuel injection is only one of the new technologies featured on the 2008 Porsche Cayenne, Cayenne S and Cayenne Turbo. For example, for the first time the Cayenne V8 engines also are equipped with Porsche VarioCam® Plus variable valve control.

Porsche originally launched its sport utility vehicle as a 2003 model that for the first time put the sport into sport utility. The original Cayenne became Porsche’s best-selling vehicle and allowed entire families to experience Porsche dynamics not only on pavement but off road as well.

Now, the second generation Cayenne can be equipped with Porsche Dynamic Chassis Control that includes active anti-roll bars that almost completely offset body roll in turns, improving handling, comfort and safety on road while also providing enhanced traction off pavement.

Also new are Dynamic Curve Lights (standard on the Cayenne Turbo and optional on the other models) to enhance the driver’s view at night on a curving roads.
Standard equipment on all versions of the 2008 Cayenne includes Porsche Stability Management, now with new functions such as pre-loading of the braking system when needed, new Trailer Stability Control and off-road ABS.

For the first time, the Cayennes come with a rollover sensor able in an emergency to trigger both the belt latch tensioners and curtain airbags, thus helping to reduce the risk of injury for all occupants in a 2008 rollover. In conjunction with the Cayenne’s six standard airbags, this system gives Porsche’s sport utility a benchmark occupant safety and protection system.

Other new features include a standard and push-button Sports mode for all Cayenne engines, a standard power rear lift gate, the availability of 21-inch wheels, a rail-mounted cargo management system and XM satellite radio.

Cleaner looking, and cleaner through the air
The new front end of the 2008 Porsche Cayenne, Cayenne S and Cayenne Turbo features a more swept back configuration with headlights moved far to the outside and covered by clear glass help to give the new model its unique face and character. The sculpting of the wheel openings and front fascia also have been updated, exterior mirrors have been redesigned and a roof spoiler has been tweaked to enhance the Cayenne’s appearance and its aerodynamic efficiency.

Where the first generation V8 models had a drag coefficient of 0.39 and the early V6 a 0.38 figure, now all three versions register at a wind-cheating and fuel-efficient 0.35 mark.

Power Up
As before, the Cayenne comes with a V6 as its basic engine, though engine capacity expands from 3.2 to 3.6 liters and cylinder angle reduces from 15 degrees to 10.6. High-pressure direct fuel injection provides a significant increase in power output with torque jumping from 229 lb-ft to 272.

The V6 can be linked to either a six-speed manual or six-speed Tiptronic S transmission. With the manual, the Cayenne reaches 60 miles per hour (96 km/h) in just 7.5 seconds, compared to 8.5 seconds for the first generation version. The same maneuver takes only 7.9 seconds in a 2008 Porsche Cayenne with the automatic gearbox, compared to 9.1 previously. Top speed on the test track is 141 mph (227 km/h), compared to 133 (214 km/h) for the earlier model.

In addition to DFI, the 2008 Porsche Cayenne S and 2008 Cayenne Turbo’s 4.8-liter V8 features VarioCam Plus valve control, a technology that enhances performance through infinite valve timing and valve lift adjustment on the intake side.

The naturally aspirated V8 in the Cayenne S develops maximum torque of 369 lb-ft compared to the previous 310 and accelerates the Cayenne S to 60 mph (96 km/h) almost half a second faster than before – in a mere 6.4 seconds, with top test track speed now reaching 155 mph (250 km/h) compared to the 150 mph (242 km/h) of the previous model.

Benefiting from two exhaust gas turbochargers, the eight-cylinder in the Cayenne Turbo develops maximum output of 500 horsepower with peak torque of 516 lb-ft, accelerating the top model in the range to 60 mph (96 km/h) in just 4.9 seconds and providing a top test track speed of 171 mph (275km/h). This means an improvement in performance in the top model by 0.3 seconds to 60 mph, with top speed up by 5 mph (9 km/h). Despite this significant improvement of performance, fuel consumption has been reduced for all new models.

Transmission

Reinforced transmissions
The Cayenne comes standard with a reinforced six-speed manual gearbox, while the Cayenne S and the Cayenne Turbo feature Porsche’s six-speed Tiptronic S automatic transmission now developed to an even higher level of perfection and available as an option also on the Cayenne.

All models also have a longer final drive ratio.
The manual gearbox is combined as standard with the Porsche Drive-Off Assistant (PDOA). This assistance system automatically applies the brakes whenever required to prevent the vehicle from rolling back when the driver disengages the clutch. The automatic transmission also offers the same kind of rollback prevention with a Hill-Holder function that prevents the Cayenne from rolling backward when setting off in a forward gear on an uphill gradient.

Chassis

Sports Button enhances performance
Standard equipment across the entire new 2008 Cayenne range is a new Sport Button. By pressing the button, the driver can choose between the Standard and Sports setup. In the Sports mode, the engine responds even more spontaneously, and models featuring an automatic transmission, air suspension and Porsche Active Suspension Management also switch to more dynamic configurations for the software that controls their hardware.

New option: PDCC for Anti-Roll Stability
Both the 2008 Porsche Cayenne and the 2008 Porsche Cayenne S come with steel spring suspensions, while the 2008 Porsche Cayenne Turbo features air suspension incorporating Porsche Active Suspension Management (PASM). This very special suspension is available as an option on the Cayenne and Cayenne S and offers not only adjustable damper control with three different settings, but the option of lowering or raising the entire body.

For the first time, PASM is available with Porsche Dynamic Chassis Control (PDCC), an active anti-roll control system that limits body roll in bends and balances out the car under nearly all driving conditions, with the body showing only a slight movement in very dynamic and sporting situations.

As a result, the Cayenne offers not only a significant improvement in handling, but also an equally significant improvement of driving stability and ride comfort.

PDCC comprises two active anti-roll bars with hydraulic swivel motors integrated in the front and rear axles. Responding very quickly and building up significant pressure of up to 2610 psi (180 bar), PDCC is able to generate appropriate support and counter-forces before the body of the Cayenne is able to sway to the side in a fast bend.

PTM for excellent traction
Intelligent Porsche Traction Management (PTM) offers an ideal combination of very good on-road and offroad driving characteristics, distributing engine power in the standard mode at a 38:62 front-to-rear ratio.

Depending on road conditions, a multiple-plate clutch operated by an electric motor and controlled electronically is able to vary the division of power as required, if necessary feeding up to 100 percent of the engine’s power and torque either to the front or to the rear wheels.

PTM not only responds to a lack of traction, but incorporates sensors measuring the speed of the vehicle, lateral acceleration, steering angle and the position and use of the gas pedal in order to provide enhanced control under the most extreme dynamic driving conditions.

In difficult terrain, PTM is able to use the off-road low-range gear integrated in the transfer case with its transmission ratio of 2.7:1, also applying a 100 percent longitudinal lock should any of the wheels lose ground contact.

PSM with an extended range of functions
Featured as standard equipment on the Cayenne, Porsche Stability Management (PSM) communicates permanently and consistently with Porsche Traction Management, but only intervenes when the Cayenne reaches the limits of driving physics.

The new Brake Assistant and the pre-loading function on the brakes significantly improves the overall quality and efficiency of the brake system: As soon as it detects application of the brakes in an emergency by means of information provided by the hydraulic PSM control unit, the Brake Assistant builds up the brake pressure required for maximum stopping power.

The brake pre-loading function, in turn, develops higher pressure within the brake system immediately when the driver takes his foot abruptly off the gas pedal and therefore helps to shorten the stopping distance required under application of the brakes.

Trailer Stability Control detects any pendulum motion on the trailer and intervenes by applying the brakes individually as required in the interest of enhanced brake stability.

A sub-function of the anti-lock brake system is that if it detects application of the brakes on loose ground, it periodically increases wheel slip during brake cycles. This off-road ABS function is particularly advantageous on snow, sand or fine gravel, building up a wedge of the material beneath the vehicle in front of the wheels to provide an additional braking effect on loose ground or slippery surfaces.

Wheels up to 21 inches in diameter
The 2008 Porsche Cayenne comes on 17-inch wheels, the Cayenne S and Cayenne Turbo are fitted with newly designed 18-inch wheels. All models are available with 19-inch wheels and all-season tires as well, while brand-new 21-inch wheels in attractive ten-spoke (Sports Wheel) or multi-spoke (Sports Plus Wheel) designs provide an even more sporting look combined with enhanced performance on the road. Yet a further benefit of these new wheels is that they are no heavier than the 20-inch wheels also available as an option.

Even higher standard of passive safety
Two full-size airbags for the driver and front passenger, two thorax side airbags and two curtain airbags in the roof frame covering both the front and rear side windows help ensure an exceptionally high Turbo 7 standard of passive safety inside the Cayenne. With the exception of the center rear seat, all seats come with belt latch tensioners. Front seats also have belt force limiters.

Apart from collisions in a longitudinal and lateral direction, the sensors now detect the risk of the vehicle rolling over. This function is provided by a new rolling rate sensor in the airbag control unit activating the belt latch tensioners and curtain airbags in an emergency.

Safety

Bracking system

Porsche braking systems are widely acknowledged as the benchmark in performance and durability. The new Cayenne models continue to uphold this standard, offering excellent deceleration—even when fully loaded with five adult occupants, a full complement of luggage and a braked trailer load of up to 7,716 lbs.

All new Cayenne models are equipped with internally vented discs all around. This proven technology ensures consistent brake temperatures—a critical factor in maintaining optimal brake performance during heavy use.

The front disc dimensions (diameter/thickness) are 12.99 in./1.26 in. on the new Cayenne, 13.78 in./1.34 in. on the new Cayenne S and 14.49 in./1.42 in. (front) on the new Cayenne Turbo.

All three models have six-piston monobloc aluminum brake calipers at the front and fourpiston equivalents at the rear. To compensate for its increased engine performance, the Cayenne Turbo has much larger front calipers.

As a visual differentiation, the calipers are finished black on the Cayenne, silver on the Cayenne S and red on the Cayenne Turbo.

Braking is assisted by a tandem booster and a large-diameter brake master cylinder. The footoperated parking brake uses a Duo-Servo system mounted on each of the rear discs. The new evolution of Porsche Stability Management (PSM) features two additional brake functions: electronic brake pre-fill prior to an emergency stop, and all-wheel brake assist.

The pistons on the front calipers on all new Cayenne models are fitted with temperature-resistant synthetic insulation elements. By reducing heat transfer from the pads to the brake fluid, consistency and performance are enhanced.

The pads themselves are equipped with individual wear sensors. When new pads are required, a warning light is illuminated in the instrument cluster. The brake lines serving each of the rear calipers feature special protection against rocks and other off-road debris.

Airbags

All Cayenne models are equipped with dual front Advanced Airbags that offer upper-body protection with an added degree of intelligence: A weight sensor in the passenger seat automatically switches the passenger airbag off when unoccupied or fitted with a child seat. These are augmented by a side-impact protection system featuring a thorax airbag in each front seat. Curtain-type airbags on each side of the roof provide optimal head protection for both rows of seats. When these are deployed, they form a protective cushion along the side of the vehicle.

To provide better detection of a head-on collision, two additional impact sensors are located at the front of the new Cayenne. As a result, the front airbags can be more accurately deployed in response to the specific characteristics of what can often be a complex impact scenario. The driver and front-passenger airbags use a gas generant based on an organic propellant. The airbags are thus lighter, more compact and easier to recycle.

A rollover detection system provides additional protection in the event that the vehicle overturns. Using sensor-acquired data, the rollover detection system enables early deployment of the curtain airbags and triggers the seat-belt pretensioners.

Interior safety features.

The new Cayenne models feature three-point seat belts at all seating locations, as well as seatbelt pretensioners (front and outer rear seats) and force limiters (front seats only). The outer rear seats are equipped with the Lower Anchors and Tethers for CHildren (LATCH) anchor system as standard. This system is specifically designed to attach the child seat directly to the seat. Porsche Child Seats are available through Porsche Tequipment.

Passive safety

The lightweight yet highly rigid steel body of the Cayenne is a decisive factor in the vehicle’s enhanced passive-safety engineering system. The triple-skin structure with robust three-box sections provides exceptional strength and occupant protection, particularly in the all-important roof and pillar areas. In the event of an accident, a system of side- and crossmembers at the front of the vehicle helps to channel impact energy in a safe and predetermined manner.

Energy is absorbed by a three-tier deformation zone that shields the passenger cell. In areas with only limited capacity for deformation, the interior is protected by hightensile steel reinforcements, including side-intrusion beams in each of the doors.

With its combination of high strength and consistent deformation properties, the multi-phase steel used throughout the Cayenne body fulfills two key safety requirements.

Tailored blanks are used throughout the vehicle to create effective crash-protection structures. Among the areas that benefit from this technology are the lateral members and roof rails.

As a result of all these measures, the new Cayenne models comply with all legal requirements for all types of crash protection, including frontal, side, diagonal and rear impact, as well as rollover damage and frontal- or sidepost impact.
