Like every Porsche, the Cayenne
Information Provided by:
poses a simple question about
performance: Can the soul of a
Porsche exist within the body of
a rugged, versatile SUV? The first
Cayenne quickly proved that such
an idea was no idle fantasy. In
fact, its character traits became
so firmly established, so focused
in their purpose, that they have
now evolved into an entirely new
generation of Cayenne models,
each one more dynamic, more
comfortable and more fuel-
efficient than ever before.
The new Cayenne.
To the point.
More Porsche than ever.
A wider range. A deeper connection.
Information Provided by:
The Cayenne models.
Take a look at the Cayenne
model range, and you will see the
Porsche principle of engineering
evolution executed in steel,
aluminum and leather. Each
example of the new Cayenne
advances its own variation
of a thesis first established
by the original Cayenne:
that the utilit y of an SUV can
coexist with the performance
of a Porsche sports car.
The Cayenne now comes in a
wider choice of models, including
the new Cayenne S Hybrid. All
of these new Cayenne models
benefit from the use of lightweight
material and technical innovation
designed to achieve a more
dynamic, more comfortable,
and more efficient Porsche.
The new Cayenne S Hybrid
uses a parallel full hybrid system
(p. 14) to harness the fuel-saving
synergies of a compact electric
motor assisting the powerful
supercharged V6 engine.
The new Cayenne and new
Cayenne S are now more powerful
and fuel-efficient, while also
delivering exceptional of f-
road capability. This has been
achieved through the use of
advanced technologies such
as Direct Fuel Injection (DFI,
p. 28), eight-speed Tiptronic S
(p. 32) and VarioCam Plus (p. 27).
The new Cayenne Turbo uses a
4.8-liter, twin-turbo V8 powerplant
to develop 500 horsepower. Its
formidable power is transferred
to the road via an eight-speed
Tiptronic S (p. 32), while Porsche
Torque Vectoring Plus (PTV
Plus, p. 40) enhances driving
dynamics and stability. Standard
features include Bi-Xenon™
headlights with Porsche Dynamic
Light System (PDLS, p. 51).
No matter which Cayenne you
choose, you’ll feel the connection
between driver and machine
deepen, the bond between you
and the road strengthen. And
isn’t that the whole point?

Just what an SUV from Porsche should be.
Design.
There is a school of thought
that an SUV must be big
and boxy, as if its brawny
ruggedness could only come
from considerable body mass.
Thankfully, Porsche designers
did not attend that school.
The new Cayenne takes a more
enlightened approach to marriage
of sport and utility. Its taut, sleek
shape is the result of Porsche’s
belief that form must follow the
demands of function, not the
whims of fashion. Consider
the lines of the new Cayenne:
The exterior is unmistakably
Porsche. The sharper profile
exudes purpose, which is
further emphasized by the
dynamic rear roof pillars and
flowing coupé-like silhouet te.
The contours of the front
section draw the eye, reflecting
the car’s excellent dynamics
at first glance. The elongated
hood is reminiscent of Porsche
race cars from the 1960s.
The front wheel arches and taut
flanks are extremely well-defined,
while the “power-domed” hood
further underlines the sheer
power and resolution within—
this is particularly dominant
on the Cayenne Turbo.
The rear wheel arches are
streamlined and muscular,
while the contoured roof
spoiler pays homage to the
Carrera GT. The tapered rear
windshield and streamlined
rear section underline the
flared wheel arches—a
design signature of the
Porsche 911 sports cars.
Inside, the desire to achieve
greater agility, flexibility and
everyday practicality led
our designers to a complete
redesign of the interior.
The rear cabin area is larger
and more variable than
before. It features split-
folding seats with fore/aft
adjustment and adjustable
backrest angle—for extra
legroom and greater comfort.
In addition, a wide range
of new materials has been
used. The changes are many,
but the reason is singular:
to sharpen the focus on
you and your passengers.

Just don’t touch the Crest.
The new Cayenne.
When we presented the first
Cayenne in 2002, there were
those who viewed the idea of
such a Porsche with skepticism.
Could it even be considered a
Porsche? After all, it had four
doors. It seemed such a radical
departure for a company whose
sports cars had always been
lightweight, nimble-handling
machines of the highest efficiency.
Yet Porsche engineers managed
to fuse those exact qualities with
those of a rugged, roomy SUV.
That core Cayenne concept
remains intact, and with good
reason. The Cayenne was an
instant success, earning both
critical praise and popular
acceptance while reaching
100,000 in sales faster than
any Porsche model ever. We’ve
just continued to improve it.
The new Cayenne is lighter—
dropping up to 364 pounds,
depending on the specification.
With less mass to move, the
power of the Cayenne translates
into quicker acceleration, faster
reflexes and shorter braking.
Its 3.6-liter, naturally aspirated
V6 engine uses Direct Fuel
Injection (DFI, p. 28), variable-valve
timing on both inlet and exhaust,
and a variable-resonance intake
manifold to do more with less.
The figures speak for themselves:
rated at 300 horsepower, with a
maximum torque of 295 lb.-ft.,
the new Cayenne records a
top track speed of 142 mph
and a 0–60-mph time of
7.1 seconds. With less fuel
consumption than ever before.
The Porsche Traction Management
(PTM, p. 36) combines active all-
wheel drive with an electronically
variable multi-plate clutch,
Automatic Brake Differential
(ABD) and Anti-Slip Regulation
(ASR). PTM ensures the perfect
distribution of drive torque to
all four wheels, whether on long
straights, through tight corners or
on surfaces with different friction
coefficients: for dynamic handling
and increased traction. Drive is
transmitted through a sport-tuned
six-speed manual gearbox (p. 32),
which ensures optimal progression
through the gears. The gear lever
throw is short and precise, with
only minimal driver effort required.
In addition to the standard
18-inch Cayenne wheels and
new larger brakes, the Cayenne
can be fitted with the optional
Porsche Ceramic Composite
Brake (PCCB, p. 54)—for
outstanding brake performance.
Another key advantage: a total
weight savings of approximately
50 percent compared with that
of equivalent cast-iron discs.
The list of standard equipment
includes Bluetooth® hands-free
phone interface, AUX-in, Partial
Leather seats, climate control,
the CDR-31 audio system with
touchscreen, universal audio
interface, cruise control and
auto headlights. For added
convenience, there’s also a
“Welcome Home” lighting
function. When you arrive at
a destination after dark, the
headlights remain illuminated for
a user-defined period, lighting
your path from the vehicle.

400 horsepower. Eight speeds. Total Porsche.
Information Provided by:
The new Cayenne S.
The “S” affixed to a Porsche model
has always been an indication of
heightened performance and
abundant reserves of power. With
the Cayenne S, the special letter
isn’t your only visual clue: The
black slats on the air intakes and
the 18-inch Cayenne S III wheels
also hint at what lies within.
Under the hood, the new, lighter
Cayenne S is fitted with a 4.8-liter,
naturally aspirated V8 engine that
deploys Direct Fuel Injection (DFI,
p. 28), VarioCam Plus (p. 27) and a
two -stage intake manifold to create
400 horsepower and maximum
torque of 369 lb.-ft. Top track
speed is 160 mph, and the
Cayenne S accelerates from
0–60 mph in as little as 5.6
seconds. All this with impressive
fuel economy, thanks to a weight
reduction of 397 pounds.
Of course, to apply exceptional
power like this requires precise
control. Drive is transmitted to
the road by the eight-speed
Tiptronic S; it includes two
ergonomic switches for
manual gear changes (p.33)
on the standard multifunction
steering wheel.
The new Cayenne S also uses
Porsche Traction Management
(PTM, p. 36). This active all-wheel-
drive system features an
electronically variable, map-
controlled multi-plate clutch, an
Automatic Brake Differential (ABD,
p. 34) and Anti-Slip Regulation
(ASR, p. 34). Working in
conjunction with the advanced
Porsche Stability Management
(PSM, p. 56), PTM ensures the
required torque split in every
driving scenario, whether on-road
or off-, during spirited driving or
leisurely journeys, or even when
towing heavy loads.
Other features that are standard
include the Bluetooth
phone interface, universal audio
interface, AUX-in and a moonroof.

The new Cayenne S Hybrid.
Since the company was founded
in 1948, we have always gone
our own way. This is the hallmark
of our independent spirit.
Only thus can we continue to
meet our high performance
standards. And yours. For the
new Cayenne S Hybrid, we
chose a highly sophisticated
technical concept, as we
felt that this would perfectly
embody the key principle of an
alternative drive: efficiency.
The new Cayenne S Hybrid
offers all the advantages of a
hybrid. And all the performance
advantages of a Porsche.
The new parallel full hybrid
system (p. 14) on the new
Cayenne S Hybrid combines a
3.0-liter, supercharged V6 engine
and an electric motor. The engine
delivers 333 horsepower, while
the electric motor generates
47 horsepower. Working in
tandem, they produce a total
output of 380 horsepower and
maximum torque of 428 lb.-ft.
The top track speed is 150 mph,
with acceleration from 0– 60 mph
in 6.1 seconds.
On the parallel full hybrid, the
electric motor and a decoupler
are integrated directly into the
drivetrain between the gasoline
engine and the eight-speed
Tiptronic S. The decoupler
ensures positive engagement
with the combustion engine,
thereby offering several
benefits—both for the driver
and the environment.
Under moderate acceleration,
the electric motor can power
the vehicle independently. The
electric motor can also be used
to recuperate energy during
braking and charge the battery.
In addition, the electric motor
can be used to boost
performance—for faster
acceleration, particularly
when pulling away.
The hybrid system also brings
significant advantages when
not driving in city traffic. The
vehicle can simply “coast”
along many stretches of road
without any power at all.
Together with the Auto Start
Stop function, the parallel full
hybrid offers exceptional levels
of performance and ef ficiency.
The “hybrid” designation on
each front fender is a discreet
reference to the innovative
power system within. Inside
the Cayenne S Hybrid, the TFT
color display in the instrument
cluster provides information on
the current energy flow. Further
driving data is displayed via the
optional Porsche Communication
Management (PCM).

A Porsche adds by subtraction.
The new Cayenne Turbo.
Porsche helped usher in a new
age in sports-car performance
when we introduced the 911
Turbo in 1974. With an engine
of compact size, that first
Porsche Turbo produced
staggering performance
figures. The new Cayenne
Turbo starts with a 4.8-liter V8
and adds t win turbochargers.
Yet its overall weight has also
been reduced by 408 pounds,
lighter than its predecessor.
An ideal power/weight ratio
that has been perfected in a
half-century’s worth of Porsche
race cars. The same principle
has been applied in the new
Cayenne Turbo. The twin-turbo,
Direct Fuel Injection (DFI) V8
engine delivers 500 horsepower
and maximum torque of 516
lb.-ft. The top track speed of
172 mph and a 4.4-second sprint
from 0–60 mph are proof of
the formula’s effectiveness.
Optimal traction and handling
stability are provided by Porsche
Traction Management (PTM,
p. 34) active all-wheel drive.
Also connecting the Cayenne
Turbo to the road are the 19-inch
Cayenne Turbo wheels and an
air suspension system, featuring
self-leveling, ride-height control
and Porsche Active Suspension
Management (PASM, p. 41). This
electronic damping control system
offers continuous adjustment
of the damping forces on each
wheel, depending on current road
conditions and driving st yle.
In the new Cayenne Turbo
interior, luxury is key. Befitting
the Cayenne Turbo’s status as
the top-of-the- line model, the list
of standard equipment includes
an interior package in Smooth-
Finish Leather, an Alcantara® roof
liner, the Bose® Surround Sound
system, a Bluetooth® hands-
free phone interface, universal
audio interface, AUX-in, USB port,
XM® Satellite Radio, Porsche
Communication Management
(PCM) with navigation module,
Adaptive Sport Seats with
memory package (18-way)
and auto headlights.
Exterior features exclusive to the
new Cayenne Turbo include
Bi-Xenon™ headlights with
Porsche Dynamic Light System
(PDLS, p. 51), larger air intakes
and a distinctive “power dome”
on the hood—a clear reference
to the enormous potential
within. Another clear statement
is the distinctive sound from
the dual -t win tailpipes.

Engines.
The drive system of the
new Cayenne S Hybrid.
To create the new Cayenne
S Hybrid, Porsche engineers
opted for a solution that
satisfies the requirements
perfectly: the parallel full hybrid.
A 3.0-liter, supercharged V6
engine and an electric motor
provide a total output of 380
horsepower and maximum
torque of 428 lb.-ft. This results
in 0–60 mph in 6.1 seconds.
The V6 engine’s use of a
supercharger ensures high levels
of torque, even at low engine
speeds. 325 lb.-ft. of torque is
available between 3000 and 5250
rpm, enabling a low-rev, economic
driving style while offering
exceptional reser ves of power.
At 288 volts, with a maximum
output of 47 horsepower, the
extremely compact and highly
efficient electric motor also acts
as a starter motor and alternator.
On the parallel full hybrid, the
electric motor is integrated
directly into the drivetrain.
The hybrid module is situated
between the transmission and
the gasoline engine. The engine
is engaged and disengaged using
a specially designed decoupler.
The complex interplay between
combustion engine, decoupler,
electric motor and battery is
controlled by the electronic
engine management system. It
receives all information on the
driving and energy status and it
controls both drive systems to
ensure optimal performance in any
driving scenario. It shuts off the
combustion engine and switches
it back on. Thanks to the ultra-
fast decoupler and instantaneous engine start-up, all of this goes
unnoticed by the driver. Under
moderate acceleration, the
Hybrid module
electric motor can power the
vehicle independently using
electricity alone, for driving
quietly through residential areas,
for example. In addition, it can
be used to boost performance—
for faster acceleration,
particularly when pulling away.
The parallel full hybrid system
also comes into its own when
driven at higher speeds. Without
drive power needed from the
engine and electric motor, the
gasoline engine is automatically
disengaged from the drivetrain
and shuts off: The Cayenne S
Hybrid continues to “coast” along.
Engine drag and the associated
deceleration effect are eliminated,
and ef ficiency is increased.
Parallel f ull hybrid syst em
The “e-power” function expands
the range in which the vehicle can
be run solely on electric power.
The throttle map is adapted
so that the combustion engine
is engaged later than when in
“Normal” mode, depending on
performance requirements.
This function is activated via a
button on the center console.

Power (hp)
Information Provided by:
Cayenne S Hybrid features a
high-voltage nickel -metal hydride
(NiMH) battery consisting of 240
cells. It provides the electric
motor with the energy required
for the vehicle to drive short
distances solely on electric power.
The compact battery is located
under the cargo floor in the
cargo area. Weighing 176
pounds, its dimensions are
16.8 in. x 36.4 in. x 11.3 in.
The battery is designed to
last without the need for any
maintenance over its lifetime. The
electric motor also functions as
a generator, so it can charge the
battery under certain conditions:
when the gasoline engine is in
part-throttle mode, and through
energy recovery during braking.
A special battery management
and cooling system maintains
a constant temperature and
protects the bat tery from
overheating. It also monitors the
charge/discharge processes. As
a result, the life of the battery
is optimized and its suitabilit y
for everyday use ensured, while
offering a high capacity: 1.7 kWh.
Systems that are usually
dependent on the output
provided by the gasoline engine,
such as climate control, power
steering and Brake Assist, run
solely on electricity in the new
Cayenne S Hybrid. As they
do not rely on output from
the engine, these functions
remain active when the vehicle
is running in electric mode
or when it is “coasting” along
with the engine turned off.
When it comes to hybrid vehicles,
the new Cayenne S Hybrid
takes a completely new path.
The engine of the new Cayenne.
All Cayenne engines use Direct Fuel
Injection (DFI, p. 28) to achieve
a significant increase in specific
power and torque, as well as better
fuel economy and lower emissions.
The new Cayenne features a
3.6-liter, naturally aspirated V6
engine with Direct Fuel Injection
(DFI, p. 28), and variable-valve
timing on both inlet and exhaust.
The engine delivers 300 horsepower
at 6300 rpm and maximum torque
of 295 lb.-ft. at 3000 rpm with a
0–60-mph time of 7.1 seconds.

Lubrication.
The V8 engines use integrated
dry-sump lubrication to help
ensure a consistent supply of oil
in load conditions, especially in
off-road terrain. The oil reservoir
is located inside the engine. This
saves space and reduces weight.
Oil is circulated around the V8
engines using a demand-driven
pump. This has been designed for
the toughest driving scenarios
on- and off- road, including
performance driving and off-road.
The V6 engine in the Cayenne
has a wet-sump lubrication
system. This helps ensure a
reliable supply of oil, even under
challenging driving conditions.
Direct Fuel Injection (DFI).
DFI injects fuel directly into
the combustion chamber at up
to 1,740 psi, with millisecond
precision using electromagnetic
injectors. The injector position
and spray geometry have
been carefully designed to
improve output, torque, fuel
economy and emissions. The
swirling of the fuel as it enters
each chamber increases the
mixing of air and fuel, thereby
enhancing combustion. By
forming the air/fuel mixture
directly in the combustion
chamber, DFI contributes to
engine cooling. As a result,
it was possible to increase
the compression ratio and,
therefore, power and efficiency.
Cooling systems.
Keeping cool is essential to any
engine. A high-performance
engine can only maintain its
maximum capabilit y over a long
service life if all components
are operating consistently
within a specific temperature
range. The engines in the new
Cayenne models are therefore
designed for optimal cooling.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20 percent of coolant
flows longitudinally through
the crankcase, the remaining
80 percent serves the cylinder
heads using the proven cross-
flow principle (from hot to cold).
On all Cayenne models, the
piston heads are cooled using
oil-spray jets integrated within
the main lubrication system. In
addition, thermal management
ensures that the optimal operating
temperature for the engines is
reached more quickly. This keeps
emissions and fuel consumption
low, even when starting from cold.
The entire cooling system is
designed for prolonged heavy-
duty use, such as off-road driving
or heavy towing applications.

Air-intake system.
Information Provided by:
The Cayenne models are all
equipped with a resonance air-
intake system. This technology
uses the pressure waves
generated by the inlet valves
to “force” air into the engine.
The effect is enhanced in the new
Cayenne and new Cayenne S by
a two-stage intake manifold. This
variable geometry combines all
the benefits of a long intake tube
(higher torque at low rpm) with
those of a shorter length (more
power at higher rpm).
The effect is literally breathtaking,
with highly impressive torque
ratings achieved across the
entire engine speed range.
Turbocharging system in
the new Cayenne Turbo.
In the new Cayenne Turbo,
the engine is assisted by twin
turbochargers arranged in
parallel—one for each bank
of cylinders. Incoming air is
passed through a filter and
compressed by the turbine
units. Its temperature is then
reduced in the twin intercooler
system, which improves
cylinder charging and limits
thermal loads on the engine.
Supercharging system in the
new Cayenne S Hybrid.
The 3.0-liter V6 engine in the
new Cayenne S Hybrid is fitted
with a supercharger. Why? For a
more direct response, even at
low revs and road speeds. This is
particularly useful when driving in
city traffic. The supercharger has
a low-temperature water-cooling
system for cooling the charge air.
Electronic engine management.
To provide comprehensive engine
control, the electronic engine
management system continually
monitors the relevant input data
from a variety of sophisticated
sensors. This data is then
compared with a corresponding
set of reference values. Based
on this information, a range of
key engine functions, such as
ignition timing and the timings
and quantities of the injections,
is seamlessly and automatically
adjusted. Other major functions
include automatic compensation
for changes in fuel quality, and
control of the variable-resonance
intake manifold geometry. On
the new Cayenne Turbo, the
engine management system
also regulates the turbo boost
pressure. The result is optimal
fuel economy and lower CO2
emissions, as well as greater
power and torque at all times.
Exhaust system.
The lightweight exhaust
systems in the new Cayenne
models are made from special
long-life stainless steel. The key
features of the catalysts are
high efficiency, faster warm-
up and a long service life.
The sport exhaust system,1
available as an option on
the new Cayenne and new
Cayenne S, provides an even
more distinctive sound. The
package also includes specially
designed dual-twin tailpipes.

Six-speed manual gearbox.
The six-speed manual gearbox
on the new Cayenne has been
specifically adapted for the
demands of high-performance
use. The gear lever throw is
short and precise, and each of
the six ratios has been selected
for optimal progression through
the gears. As the center console
rises to meet the dashboard, the
gear lever is close at hand —for
an even more engaging drive.
The standard upshift
indicator in the instrument
cluster helps to reduce fuel
consumption still further.
Eight-speed Tiptronic S with
Auto Start Stop function
is also available as an
option on the Cayenne.
Standard on the Cayenne.
Eight-speed Tiptronic S.
The new eight-speed Tiptronic S
features a particularly wide ratio
spread. First gear is designed
for optimal acceleration when
pulling away, and greater
performance when tackling
ascents and towing loads in
off-road terrain. Top speed is
reached in 6th gear. The t wo
upper gears are used to lower
the revs at high speed, thereby
enhancing fuel economy and
occupant comfor t. On the highway
in par ticular, driving at low rpm’s
will significantly reduce the
noise level inside the vehicle.
In automatic mode, the driver
can influence gearshifts on the
Tiptronic S using the throttle
and brakes alone. Tiptronic S
automatically adapts the gearshift
points for performance driving—
equally, if a more conservative
driving style is detected, the
system selects a gearshift
point that offers maximum
fuel economy. Under heav y
braking, Tiptronic S shifts down
to maximize engine braking.
An electric pump is used to
maintain the required pressure
of the transmission fluid, e.g.,
to transmit high levels of torque
at lower engine speeds.
The standard three-spoke
multifunction steering wheel
in conjunction with Tiptronic S
has two ergonomic switches
for manual gear changes. One
press forward with the thumb
and Tiptronic S shifts up. One
pull backward with the index
finger and Tiptronic S shifts
down. Either the right- or left-
hand switch can be used.
Naturally, you can also change
gear using the gear selector
lever on the center console.

Porsche Traction Management
(PTM) on the new Cayenne,
Cayenne S and Cayenne Turbo.
Porsche Traction Management
(PTM) is an active all-wheel-drive
system with an electronically
variable, map- controlled multi-
plate clutch, Automatic Brake
Differential (ABD) and Anti-
Slip Regulation (ASR).
Torque is distributed bet ween the
front and rear axles by means of
the electronically variable multi-
plate clutch. For the toughest off-
road terrain, the differential can
be locked using the PTM control
on the center console. With the
aid of onboard sensors, the status
of the vehicle is continuously
monitored and the front/rear split
is adjusted to match changing
driving conditions. The sensors
are used to collect a range of
data, including the rotational
speed of all four wheels, the
lateral and longitudinal
acceleration of the car, and
the current steering angle.
If, for example, the rear wheels
threaten to lose traction under
acceleration, a greater proportion
of drive torque is automatically
transmitted to the front axle by a
more positive engagement of the
multi-plate clutch. In addition,
ASR minimizes wheelspin. During
cornering, the optimal level of
engine torque is distributed
to the front wheels to ensure
excellent lateral stability.
In conjunction with advanced
Porsche Stability Management
(PSM, p. 56), PTM helps to ensure
the perfect distribution of drive
torque for optimal traction in
most road scenarios, whether
All -wh eel dr ive on the Cayenn e, Cayen ne S an d Cayenne Turbo
on long straights, through tight
corners, or on surfaces with
different friction coef ficients.
If one of the wheels is about
to lose traction, PTM uses
the ABD function to apply the
corresponding brake. As a result,
more drive is automatically
transferred to the opposite
wheel. If both wheels on one
axle are in danger of slipping,
ASR immediately intervenes
and modifies engine output
to maintain drive. As well
as enhancing traction and
active safety, Porsche

Porsche Traction Management
Information Provided by:
(PTM) on the new
Cayenne S Hybrid.
The new Cayenne S Hybrid
features a permanent all-wheel -
drive system with self-locking
center differential. This provides
a standard torque split of 58
percent to the rear and 42
percent to the front. If one of
the wheels is losing grip, the
self-locking center dif ferential
transmits the torque to the
axle offering the highest level
of traction. The ASR and ABD
systems work in the same way as
in the PTM on the new Cayenne,
Cayenne S and Cayenne Turbo.
On the Cayenne S Hybrid, PTM
also enables variable distribution
of engine torque between the
rear wheels, thereby enhancing
steering precision and driving
dynamics. Specifically, this
means that when the vehicle
enters a corner at high speed,
moderate brake pressure is
applied to the inside rear wheel.
This supports the steering
motion of the vehicle, thereby
improving its cornering dynamics.
Standard on the
Cayenne S Hybrid.
Porsche Hill Control (PHC).
A standard feature on all new
Cayenne models, Porsche Hill
Control (PHC) provides downhill
assistance by maintaining a
constant rate of speed on
extreme downhill gradients. It
is activated via a switch on the
center console. The speed can
be set to between 2 and 19 mph.

The new Cayenne: perfectly at home on many terrains.
Off-road capability.
With intelligent all-wheel-drive
technology, the new Cayenne
is engineered for many kinds
of terrain, from steep ascents
leading to snow-covered mountain
lodges to mud and gravel and
everything in between. The
drive systems featured on the
new Cayenne models deliver
exceptional torque to give the
driver plenty of power in reserve
to take on almost any terrain.
Operating concept.
With the help of Porsche Traction
Management (PTM), Cayenne
is designed to cope with even
the most demanding off-road
scenarios. Simply move the main
off-road control on the center
console forward or backward to
select one of up to three off-road
modes (depending on the model).
Available on the Cayenne,
Cayenne S and Cayenne Turbo,
this function readies the Cayenne
for off- road use or reverts the
setting to normal road driving.
In Off- road Mode 1, for example,
the maps for all relevant
systems, such as the ABS,
are adapted to provide optimal
traction. In addition, Porsche
Hill Control (PHC) is activated
and Off-road Level is selected
on vehicles featuring air
suspension with PASM. If that’s
not enough, the air suspension
can be raised further to Special
Off-road Level to increase
the approach/departure
angle and wading depth.
Push the off-road control
forward again on the Cayenne,
Cayenne S and Cayenne Turbo
to activate Off-road Mode 2.
For even greater traction on
difficult terrain, the multi-plate
clutch can be fully locked.
The electronically variable rear
differential on the optional
Porsche Torque Vectoring Plus
(PTV Plus) is integrated within
the all-wheel -drive system.
This automatically helps to
ensure the optimal distribution
of drive torque on particularly
uneven surfaces. If one of the
rear wheels begins to slip,
the rear differential varies the
amount of torque transmitted
through each driveshaft,
thereby restoring traction. In
Off-road Mode 3, the main off-
road control fully locks the rear
differential. Then both rear
wheels receive the same amount
of torque, regardless of surface
conditions. The optional PDCC
(p. 43) enables greater wheel
articulation in all three modes,
improving traction further.
For ef fective prevention of
damage to the underside of
the vehicle, all new Cayenne
models can be equipped with
optional off-road underbody
protection, comprising rock
rails with integrated skid
plates, a reinforced engine-bay
guard, additional protection
for fuel tank and rear axle,
and a second towing lug.
