THE PORSCHE® CAYENNE®: A SPORT UTILITY BY NATURE, NOT JUST BY NAME

ATLANTA – By drawing on the full depth of its long and proud heritage in

engineering and design, as well as successes from the streets of Le Mans to the

sands of Dakar, only Porsche is in a position to build a sport-utility vehicle (SUV)

that is not just another utility vehicle, but a vehicle with dynamic capabilities that

truly can be described as sporting.

 

The Porsche Cayenne demonstrated its on- and off-pavement capabilities during

development testing on the twisting, high-speed road racing circuit at Germany’s

famed Nürburgring as well as in Arctic snow and ice, in the sun-baked environment

of Australia’s Outback, in the sands of Dubai, and on the slick and steep surfaces

of North America’s Rocky Mountains. Now the Cayenne S and Cayenne Turbo are

ready to demonstrate their capabilities in the hands of Porsche customers.

 

“The Cayenne is the first vehicle to really put the sport into sport-utility,” says

Frederick J. Schwab, president and CEO of Porsche Cars North America. “I know

that others have made a similar boast, but we’re confident that the Cayenne will

more than live up to that claim. The Cayenne may have the architecture of an

SUV, but it has the soul that is part of every Porsche product,” Schwab adds.

 

The Cayenne takes its name from the one of the very hottest of red peppers,

recognized around the world as a symbol for zestful spiciness. With as much as

450 horsepower, with 0-to-62 mph sprint times as quick as 5.6 seconds, and with

Porsche Traction Management and other innovative technologies that provide

sure-footedness in high-speed lane changes and for crawling up slick rock and

down steep and rocky trails, the Cayenne is the first true sport-utility.

 

 

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, the Cayenne is the first Porsche to provide such true utility.

 

As Porsche enthusiasts already know, the “S” badge signifies a truly special

Porsche model, not merely a trim upgrade or option package.

 

The Cayenne S maintains a tradition that dates to 1952 with the S version of the

original Porsche, the 356. Since then, the S badge has been worn by the famed

911S that arrived in 1967 and subsequently by such outstanding vehicles as the

Boxster® S and the 911® Carrera® 4S.

 

For the launch of the Porsche SUV, the Cayenne S earns its special designation

thanks to its 340-horsepower (SAE), 4.5-liter, normally aspirated V8 engine, a

powerplant designed and manufactured by Porsche that ranks the Cayenne S among

the strongest of all sport utilities. It features an all-new, six-speed Tiptronic® S

transmission and introduces Porsche Traction Management four-wheel-drive

technology that provides outstanding performance during maneuvers on a variety

of paved and unpaved terrain.

 

The Cayenne S carries such standard equipment as Porsche Stability Management;

front, side and curtain airbags; a Bose® Cabin Surround Sound System; leather

upholstery and automatic climate controls.

 

The Cayenne S has a base price of $55,900 in the United States and $78,250

in Canada.

 

 

With twin turbochargers boosting the output of its 4.5-liter V8, the Cayenne Turbo

delivers 450 horsepower and 457 pound-feet of torque, power that propels it

from a standing start to 62 mph (100 km/h) in a mere 5.6 seconds and to a top

track speed of 165 mph (266 km/h).

 

But the Cayenne Turbo is just as capable off-pavement, thanks to its combination

of Porsche Traction Management with standard air suspension that can provide

nearly 11 inches of ground clearance for traversing rough terrain.

 

Like the Cayenne S, the Cayenne Turbo comes with such standard equipment as

Porsche Stability Management; a six-speed Tiptronic S transmission; front, side

and curtain airbags; full leather upholstery and automatic climate controls. The

Cayenne Turbo adds such features as an aluminum-trimmed interior and the new

Porsche Communications Management technology that includes a navigation

system and Bose Cabin Surround Sound System.

 

The Cayenne Turbo has a base price of in the United States of $88,900 and

$125,100 in Canada.

 

Production plans for the Cayenne were announced in the summer of 1998, when

it was disclosed that the Porsche SUV would have permanent four-wheel drive and

genuine off-pavement capabilities, but also would achieve Porsche benchmarks

for ride and handling. This Porsche SUV would be built at a new, state-of-the-art

assembly center at Leipzig, Germany, where Porsche also has constructed on- and

off-pavement testing facilities.

 

While the Cayenne would be built on the same platform as a new Volkswagen

SUV, Porsche, which would develop new engines to power its SUV, would lead

the design and engineering efforts.

 

 

The new Porsche V8 is a 4.5-liter unit with 32 valves (two intake and two exhaust

valves per cylinder), Porsche’s VarioCam® technology, and integral dry sump lubrication.

The two banks of cylinders are placed at a 90-degree angle.

 

The engine is designed to operate smoothly at an angle of 45 degrees off

horizontal, thus providing optimum off-pavement abilities. This required modification

of the oil circuit and crankcase-venting system, most notably separate oil re-flow

ducts leading from the cylinder heads into the oil sump. Separation of the oil circuit

from the vent ducts enables engine oil to flow quickly and directly back to the oil

sump to maintain a sufficient oil supply at all times. On extreme gradients, an

efficient supply of oil is also guaranteed by added oil extraction from the rear

section of the oil sump, by the oil intake opening for the main oil pump being

lowered right to the bottom point, and by a baffle wall in the oil sump.

 

The V8 shares much of its internal architecture with the water-cooled six-cylinder

engine that was developed to power the Porsche Boxster. However, Porsche

engineers developed specific components and dimensions for the Cayenne’s

new V8. For example, while the 3.66-inch (93 mm) cylinder bore is the same as

the Boxster’s, the V8 has a longer stroke of 3.27 inches (83 mm).

 

The V8 has a two-piece cylinder head similar to that developed for the powerful 911

Turbo, and the Cayenne engine’s cylinder head makes use of an aluminum/silicon

alloy that can withstand very high temperatures.

 

As with all other Porsche models, the new V8 makes use of Porsche’s VarioCam

technology. For the Cayenne’s V8, VarioCam can adjust the camshafts by as much

as 25 degrees, ensuring outstanding torque characteristics as well as optimum

fuel efficiency and lower emissions.

 

Engine coolant is distributed to the crankcase and cylinder heads by a distribution

pipe located above the transmission. The water pump, mounted at the front of

the engine, pumps coolant through a pipe located in the interior of the engine’s V.

Approximately 20 percent of the coolant flows through the crankcase in a

lengthwise direction with 80 percent flowing through the cylinder heads in a

“crossflow” architecture from the hot to the cold side. Heat from the engine oil

is fed into the coolant through an oil/water heat exchanger.

 

 

The stainless steel exhaust system features an exhaust pipe for each row of cylinders

that is connected downstream of the main catalysts by a crossover pipe. This

architecture allows enhanced torque at low engine speeds. The pre- and main

catalysts are metallic, allowing thinner design of the coated inner walls. This

system also provides a larger overall area within the catalyst ducts, ensuring higher

efficiency, longer service life and more rapid build-up to the temperatures required

for maximum catalyst efficiency.

 

The catalysts are controlled by two oxygen sensors. This dual-sensor control

minimizes exhaust emissions, enabling both the Cayenne S and the Cayenne

Turbo to meet LEV (low emission vehicle) standards in the United States and to

fulfill the EU4 standards that go into effect in Europe in 2005.

 

The normally aspirated engine in the Cayenne S is rated at 340 horsepower (SAE)

and provides 310 pound-feet of torque all the way from 2,500 rpm to 5,500 rpm.

Working in conjunction with the new six-speed Tiptronic S transmission, the

normally aspirated 4.5-liter V8 propels the Cayenne S from a standing start to

62 mph (100 km/h) in only 7.2 seconds. The Cayenne S can achieve a top speed

of 150 mph (242 km/h) on the test track.

 

The Cayenne Turbo is powered by a similar 4.5-liter V8, but two turbochargers

recycle the engine’s exhaust gases and boost its power to a staggering 450

horsepower (SAE) at 6,000 rpm and to a whopping 457 pound-feet of torque

throughout the 2,250 to 4,750 rpm range.

 

Because of such higher loads, the Cayenne Turbo has cylinder heads made of

special high temperature-resistant aluminum alloy similar to that used in Porsche

racecars. The intake ducts are modified for the greater fuel/air mixture and the

cylinder head features double valve springs on the exhaust side to ensure maximum

engine performance. The Turbo also has special forged pistons and additional

oil injection cooling jets.

 

The Tiptronic S transmission is specially tuned for the increased power of the

Turbo engine.

 

As on the Porsche 911 Turbo, the Cayenne Turbo’s boosters are in parallel

arrangement. Small intake and short exhaust manifolds and a mixed-flow turbine

with reduced mass inertia ensures response and performance, eliminating so-called

turbo lag.

 

The turbo housing is made of high quality cast steel, assuring temperature control

and optimizing combustion under full load. The compressed air flowing out of the

turbine is cooled to provide a high cylinder charge and to reduce component

temperatures. Intake air flows to the two compressors through separate air filters

for the left and right cylinder banks. Finally, the compressed air flows through

separate intercoolers positioned in front of the left and right wheel arches.

 

Bypass valves are integrated into the turbine housings and turbocharger pressure

is adjusted through a joint cycle valve controlled by the engine management

system. Maximum turbocharger pressure is approximately 23.2 pounds per

square inch (1.6 bar) and is reached at an engine speed of 2,250 rpm. Boost

pressure then reduces slightly, to 21.7 psi (1.5 bar), where it remains until the

engine reaches its maximum horsepower at 6,000 rpm.

 

Compared to the Cayenne S engine, the Turbo requires additional lubrication and

cooling, which are provided by separate feed lines. To achieve optimum

performance in off-pavement conditions, the turbochargers are equipped with an

oil retention tank and check valve.

 

 

Both Cayenne models will have permanent four-wheel drive, an inter-axle

differential lock and additional low-range gears, Porsche Stability Management

(PSM), and the ability to tow 7,716 pounds (3,500 kilograms). Both Cayenne

models ride on wheels that range from 18 inches to 20 inches in diameter.

 

“Historically, Porsche has been at the forefront of all-wheel-drive design,” notes

Schwab. “It began with the Lohner-Porsche in 1900 and was highlighted by the

Porsche 959 in 1985, and that car’s victory in the Paris-Dakar marathon. The

Cayenne is a natural next step for Porsche.”

 

To ensure the Cayenne is both a true Porsche and a true SUV, it has gone

through several years of comprehensive testing in remote locations across the

globe. Test vehicles were on the Porsche development track at Weissach as

early as the spring of 1998, and in addition to Germany’s famed Nürburgring,

on-track tests also were done at Nardo (Italy) and on Hockenheim, home of the

annual German Grand Prix. The Cayenne and its various components and systems

also were tested in the snow and ice in Sweden and Canada; on the sand and rock

of Dubai; in the harsh environment of the Australian Outback; in the mountains of

the American West, Spain and in the Alps; and on hundreds of thousands of miles

of highways around the world.

 

The Cayenne had to satisfy not only Porsche’s extreme performance and

quality standards, but it had to meet the utility and reliability expectations only

Porsche engineers demand from an SUV.

 

 

For the Cayenne, Porsche engineers developed the Porsche Traction Management

(PTM) permanent four-wheel drive system, an air suspension system with a

self-leveling feature and six adjustable ride height positions, and Porsche Active

Suspension Management (PASM), an electronically variable damping system that

stabilizes body sway during sudden gas or brake pedal applications or when

driving in rough terrain. These systems work together to ensure that the Cayenne

offers both supreme on-pavement and outstanding off-pavement driving qualities.

 

These systems also work in conjunction with PSM (Porsche Stability Management),

which intervenes when the vehicle is driven to the limit of adhesion and stabilizes

the Cayenne in oversteer or understeer conditions to keep it headed in the

direction the driver intends.

 

Porsche Traction Management (PTM), which is standard on both Cayenne models,

significantly improves dynamic performance and handling.

 

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. However, whenever necessary, it 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 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 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.

 

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

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.

 

Porsche Stability Management (PSM), also standard on both Cayenne models,

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 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.

 

The 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 Cayenne ample ground clearance,

up to 10.75 inches (273 mm) with the air suspension system.

 

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 Cayenne’s

turning radius is 39 feet (11.9 meters).

 

The rear axle is another new Porsche development. The rear axle configuration

is an elaborate multi-arm concept easily able to handle both high traction forces

and the 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 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.

 

With the steel spring suspension on the Cayenne S, 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.

 

For those needing more ground clearance, an optional air suspension is available

on the Cayenne S and is standard on the Cayenne Turbo.

 

With the air suspension that is standard on the Cayenne Turbo and available as

an option on the 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 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 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 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 more firm 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 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 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 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 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 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 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 Cayenne’s outstanding road performance does not come at the expense of its

off-pavement capabilities. Due to its intelligent four-wheel drive, the Cayenne is

able to handle minor off-pavement conditions without requiring modification of

the traction systems.

 

When driven on rough terrain, the 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, 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 air suspension in the Cayenne Turbo 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 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 Cayenne Turbo’s 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 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.

 

Both models are equipped for water crossings up to 21.85 inches (555mm) when

set to the special off-pavement level 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 Cayenne

S allows it to traverse water up to 19.7 inches (500 mm) in depth.

 

In the future, Porsche will offer the Advanced Offroad Technology Package for

the most extreme off-pavement conditions. Apart from special side protection

and a steel plate under floor panel around the radiator, this package includes 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, which are

hydraulically activated and deactivated by a switch in the center console. This

increases 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 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) to provide the additional stability required for on-pavement driving.

 

To ensure maximum braking efficiency, Porsche engineers equip the Cayenne with

13.78-inch (350 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. The front and rear rotors are 1.34

inches (34 mm) and 1.10 inches (28 mm) thick, respectively. Anti-lock braking

technology is standard.

 

Because of the risk of contamination under off-pavement conditions, the

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 is the first Porsche with a foot-operated parking brake, which allows

room for a large storage compartment in the center console. An interim gear

further reduces brake forces to provide additional support. The system, which

also features a self-adjusting brake cable, allows drivers to safely and securely

park a fully laden Cayenne on a 55 percent gradient.

 

The Cayenne S and Cayenne Turbo ride on standard 18-inch light-alloy wheels

and 255/55 R 18 tires. Optional equipment includes 19- and 20-inch wheels and

a variety of high-performance and winter weather tires.

 

Cayenne wheels are built in a process called flow-forming, which reduces weight,

depending on wheel size, by 2.2 to 3.3 pounds (1-1.5 kg) per wheel.

 

Porsche’s know-how in lightweight steel technology plays a significant role to

ensure both the outstanding stiffness and safety of the Cayenne’s body structure.

 

 

Some 60 percent of the 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 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 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 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. Two-stage gas

generators that are designed to reduce unnecessary loads on the occupants in the

event of a minor accident activate the airbags for the driver and front passenger.

The Cayenne’s new side impact safety system includes side airbags integrated

into the front seats and a curtain airbag fitted into the roof frame that protects

occupants in both the front and rear seats. This curtain airbag is effective in side

impacts and in the event of an impact with a narrow obstacle such as a pole or tree.

 

All five seats in the 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 has gone to great lengths to ensure the 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, standard

on both models, bears a multi-colored Porsche crest.

 

Other standard equipment on both models includes an alarm system, central

locking (with remote control from the ignition key), an on-board computer, tinted

and heat-insulated glass, electric windows, electrically adjustable front seats, an

expansive leather interior, automatic air conditioning with an activated carbon filter,

and the 350-watt Bose Cabin Surround Sound System with a CD player and 14

speakers.

 

 

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, and when both

are folded down, cargo capacity increases to 62.51 cubic feet (1,770 liters).

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.

 

Additional standard features on the Cayenne Turbo include Bi-Xenon headlights, an

electrically adjustable heated steering wheel, front seats with memory function,

metallic paint, Porsche Communication Management (PCM) and Porsche

ParkAssistant technologies.

 

The Turbo’s headlights use sensors that measure the driver’s steering angle and

road speed and adjust the headlight direction to provide outstanding illumination

of the road ahead.

 

The new PCM system features a navigation module, an on-board computer,

antenna diversity and the Bose sound system.

 

The Turbo’s leather interior has aluminum details in areas such as the dashboard,

doors and control panel trim.

 

In anticipation of the Cayenne’s arrival, Porsche Cars North America launched the

Cayenne Crossing Initiative, a multi-year program dedicated to reclaiming America’s

paved and unpaved roads. Chaired by actor James Brolin, the program includes

a variety of U.S. road restoration and maintenance projects along a route that

stretches from coast to coast.

 

Cayenne Crossing Initiative partners include Treadlightly!, the Illinois Department

of Transportation, the San Bernardino National Forest Association and the Porsche

Porsche® Technology Features

VarioCam® Plus

Porsche offers its VarioCam or VarioCam Plus technology on the engines of all

of its models, including the Cayenne®.

 

VarioCam Plus was developed for the 911 Turbo to optimize dynamic performance

while reducing fuel consumption and exhaust emissions and improving engine

refinement and ensuring smooth operation.

 

VarioCam involves intake camshaft adjustment (VarioCam) and intake valve lift

control (Plus).

 

The valve adjustment system is accomplished by switching cup tappets through

an electrohydraulic switching valve. With two cam profiles on the intake shaft, the

engine is able to operate with the appropriate lift curve.

 

The cup tappets comprise two interacting tappet elements locked together by a

bolt. This creates a direct link between the inner tappet and the small cam and

between the outer tappet and the large cam. A hydraulic compensation unit for

valve play is integrated into the tappet’s force flow line.

 

When the engine is at idle, valve lift is controlled by the small cams (to a limit of

3.6 millimeters (0.1417 inches) and valve timing is optimized to keep any valve

overlap to a minimum. The small valve lift reduces friction, significantly increases

the charge motion (thanks to the very short opening times) and reduces emissions

from any previous combustion within the cylinder. Another advantage is the

considerable reduction in fuel consumption and emissions – by as much as 10

percent – as well as a much higher standard of idling quality.

 

Under partial load, the engine runs with internal recirculation of exhaust gases to

minimize throttle effect and to reduce fuel consumption. To achieve this goal,

valve lift is shifted to a large overall area to draw in exhaust gases.

 

Then, under full load, superior torque and output are ensured by a highly efficient

gas charge cycle with minimum losses, yet with an uncompromising cam contour

of a maximum of 11 millimeters (0.4331 inches) of valve lift and suitably adjusted

opening and closing times during the valve cycle.

 

VarioCam Plus also enhances engine start up and reduces emissions while the

engine warms up.

 

The Motronic ME 7.8 engine management system used on Porsche sports cars

is designed specifically for Porsche’s requirements and governs both camshaft

adjustment and valve lift control. The Cayenne uses the Motronic ME 7.1.1

engine management system. The systems make adjustments based on factors

such as engine speed, gas pedal position, engine oil and coolant temperature

and the gear in which the car is operating. Driver input is compared with control

maps within the system and the control unit decides within milliseconds how

VarioCam and VarioCam Plus should respond.

 

 

In addition to the five-speed Tiptronic S transmission in the 911® and Boxster®,

Porsche offers a six-speed Tiptronic S in the Cayenne. This latest development

is tailored specifically to the high torque and power level of the Cayenne Turbo,

and thus also is ideal for the Cayenne S model.

 

This new six-speed Tiptronic S features modified shift units and a special torque

converter. The system provides a wider range of individual gear increments and

retains the driver’s option to shift gears manually by tipping the selector lever on the

center console or simply by pressing the upper part of the thumb switches on the

steering wheel to shift up and pressing the lower part of the switch to downshift.

 

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

selector lever 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 currently engaged 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.

 

In automatic mode, Tiptronic S adjusts to various control maps based on the driver’s

style of driving and the route. The range of shift points extends from a particularly

economic version 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,

for example on a winding road, and 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, the 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;

• Downshifts to the next lower gear to optimize engine braking;

• Increment upshift delays shifting into a higher gear after an active downshift;

• Retention of gears in a bend to prevent upshift;

• Hill recognition that retains lower gears as long as possible in uphill or downhill

gradients.

 

To reduce the possibility of an improper shift in rough terrain, the steering wheel

paddles are deactivated when the off-pavement 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 S

uses gearshift control maps that ensure optimum power in rough terrain.

 

Another feature of the Tiptronic S in the Cayenne is a hill-holder function that prevents

the car from rolling backward when setting off in a forward gear, even on a speed

grade.

 

Porsche Traction Management (PTM) is a new generation in four-wheel drive that

is standard on every Cayenne. PTM significantly influences the Cayenne’s dynamic

performance by coordinating the vehicle’s outstanding power and torque, its sporty

and agile handling, and its excellent driving dynamics with superior performance

off the beaten track.

 

In normal conditions, PTM feeds 62 percent of the engine’s power to the rear wheels

and 38 percent to the front wheels. However, through the use of a multiple-plate

clutch, the driver can vary the power split as needed, if necessary feeding 100

percent of the engine’s torque to the front or rear wheels.

 

The map-controlled front-to-rear lock and the optional rear axle differential lock not

only respond to lack of traction on the front or rear wheels, but also incorporate

sensors within the management system to measure such things as vehicle speed,

lateral acceleration, steering wheel angle and operation of the gas pedal. PTM

thus determines the optimum lock on both axles and distributes drive power as

actually required to the front and rear wheels.

 

PTM therefore acts as an intelligently networked electronic system that provides

superior driving stability and safe lane change behavior both at high speeds and

when driving on snow and ice at moderate speeds.

 

This innovation offers an impressive range of outstanding results, including:

• Excellent driving stability and traction in all situations, regardless of the

frictional coefficient;

• Better steering provided by the front-to-rear differential lock opening up to

avoid any understeer effect;

• Better control when driving to the limit thanks to the front-to-rear differential;

• Enhanced directional stability and better road grip by operating the

front-to-rear lock as required;

• Better traction by increasing locking action before the wheels start to spin.

 

Porsche Stability Management (PSM) remains consistently in touch with PTM,

but intervenes only when the vehicle reaches its limits. Coordinating essential

systems such as ABS (Anti-lock Braking System), ASR (Automatic Slip Regulation)

and ABD (Automatic Brake Differential), PSM cuts in immediately under critical

over- or understeer conditions and tells PTM to open up the locks to restabilize

the vehicle by applying the brakes specifically on individual wheels.

 

 

The Cayenne successfully combines outstanding performance on the road with

equally outstanding off-pavement abilities. Indeed, it is already a genuine master

off the beaten track in its “basic” configuration, intelligent four-wheel drive enabling

the Cayenne to easily cross light terrain without any modification of the traction

systems.

 

On rough terrain, the Porsche Traction Management (PTM) system uses the

reduced-ratio gearbox featured as standard equipment. With its reduction ratio

of 2.7:1, the reduction gearbox is ideal for even the most extreme maneuvers,

easily handling steep gradients and, in particular, downhill passes.

 

Activating the low-range mode by means of a toggle switch on the center console,

the driver can automatically prepare several control systems for off-pavement

driving conditions: PTM switches over to the reduced ratio for off-pavement

requirements and changes to a special off-pavement control map activating the

differential locks, PSM responds by setting ABS and ABD to a special traction

mode for all-terrain motoring, and the air suspension featured as standard in the

Cayenne Turbo automatically lifts the entire vehicle up to its off-pavement level.

 

Porsche is the first carmaker to offer this combination of systems all controlled

by one central switch and thus significantly facilitating operation of these systems

when driving under extreme all-terrain conditions.

 

Porsche Communication Management (PCM) operates at the speed of light.

 

Using Porsche’s MOST (Media-Oriented Systems Transport) technology, PCM

uses light wave conductors to exchange multi-media data in every Porsche model.

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 ensures

high-quality audio transmission for radio, CD player 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 is displayed, within the instrument

cluster, such information as 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 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 the frequency of selected radio stations.

 

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 new buttons to the right of the display provide direct access to the Set (Set

button) and Return (button with a bent arrow) functions, 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;

• 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.

 

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.

 

A special feature of POSIP is that the airbags are able to ensure the same protection

even in an open convertible.

 

Housed in the door panel, the airbag modules differ from conventional units through

their large volume and airbag geometry. In a collision from the side, this ensures

not only the usual protection from chest to head, but also protects the driver’s

and front passenger’s head from hitting an obstacle at the side. This standard

is met regardless of the fore-and-aft position of the seats.

 

For the Cayenne, this side impact protection includes a new curtain airbag fitted

into the roof frame. This curtain protects passengers sitting in the rear seat as

well as the driver and front-seat passenger. The system is designed to provide

protection even when struck by a narrow obstacle such as a pole or a tree.
