Power, precision and the potential for more.
Cayenne S.
The Porsche ‘S’ has long been a mark
of heightened sports performance and
abundant reserves of power. On the
Cayenne S, it also stands for strength,
agility and efficiency.
At the heart of the car is a naturally aspir -
ated
4.8-litre V8 engine featuring direct
fuel injection (DFI, p. 40), VarioCam Plus
(p. 39) and a t wo -stage intake manifold.
This helps to reduce fuel consumption
and emissions
1), while ensuring maximum
output. In short: 294 kW (400 hp), max -
imum torque of 500 Nm and a top speed
of 258 km/ h. The Cayenne S accelerates
from 0 to 100 km/ h in as lit tle as 5.9 sec-
onds. Fuel consumption has been reduced
by up to 23 % and CO2 emissions by as
much as 26 %.1) The weight of the car
has also been lowered by 180 kg.
1)
Drive is transmit ted to the road with
smoothness and precision by the
standard eight-speed Tiptronic S, which
includes gearshift controls on the
steering wheel. The result: optimum

use of the available power reserves.
Of course, to apply exceptional power
like this effectively, it needs to be
harnessed and controlled. For example,
by Porsche Traction Management (PTM,
p. 47). On the Cayenne S, this active
all-wheel drive system features an
electronically variable, map-controlled
multi-plate clutch, an automatic brake differential (ABD) and anti-slip
regulation
(ASR). Working in conjunction with ad-
vanced Porsche Stability Management
(PSM, p. 68), PTM ensures the required
torque split in every driving scenario. On
or off road. During performance driving,
as well as on leisurely journeys or when
towing heav y loads.
The design also reflects the impressive
power within. The black slats on the air
intakes make them appear larger, and
the car wider. Other distinctive features
include the 18-inch Cayenne S III wheels.
The Porsche ‘S’. A mark to which the
Cayenne S holds true.

Reduced weight, lower fuel consumption, fewer emissions.
At Porsche, we believe less is more.

Cayenne Tu r b o.
Understatement coupled with clear state -
ments: lower fuel consumption, faster
acceleration.
1) Supreme engineering that
speaks for itself. In short, every thing
you’d expect from a Turbo.
Another clear statement is the distinctive
sound from the twin dual-tube tailpipes.
Produced by the 4.8-litre t win-turbo V8
engine that delivers 368 kW (500 hp) and
features direct fuel injection (DFI, p. 40).
The car has a top speed of 278 km/ h
and the benchmark sprint from 0 to
100 km/ h is completed in 4.7 seconds.
Maximum torque is 700 Nm. Here too,
fuel consumption has been reduced by
23 % and CO
2 emissions by 25 %.1)
Not least thanks to a weight saving of
185 k g.

Optimum traction and safet y are pro -
vided by Porsche Traction Management
(PTM, p. 47) active all-wheel drive. Also
connecting the car to the road are the
19-inch Cayenne Turbo wheels – wheels
up to 21 inches in diameter are available
as an option. The chassis on the Cayenne
Turbo is equipped as standard with air
suspension featuring self-levelling and
ride-height control, as well as Porsche
Active Suspension Management (PASM,
p. 57). This electronic damping control
system offers continuous adjustment
of the damping forces on each wheel –
depending on current road conditions
and driving st yle. This enables greater
car control, improving safety and
comfor t. Comfort is also key in the Cayenne Turbo
interior. Standard equipment comprises
an interior package in smooth-finish
leather, a rooflining in Alcantara and an
electrically adjustable steering column.
Also fit ted as standard: the BOSE®
Surround Sound System, Porsche

Communication Management (PCM, p. 90)
with navigation module, adaptive sports
seats with comfort memory package
(18-way), Tyre Pressure Monitoring (TPM,
p. 58), automatic headlight activation
and automatically dimming exterior and
interior mirrors.
Exterior features exclusive to the
Cayenne Turbo include Bi-Xenon main
headlights with Porsche Dynamic Light System (PDLS, p. 63), larger air intakes
and a distinctive ‘power dome’ on

the bonnet – a clear reference to the
enormous potential within.
Following our long established principles,
the Cayenne Turbo blends phenomenal
performance with outstanding comfort
and efficiency. It does so in st yle, but
without ever compromising on any one
in particular. Because we believe that
less can also mean more.

E-power button.
The ‘e-power’ but ton can be used to
expand the range in which the vehicle

can be run solely on electric power, when
heading out of a residential area, for
instance. The throt tle map is adapted so
that the combustion engine is engaged
later than in ‘Normal’ mode depending
on performance requirements. This is
activated via a but ton on the centre

console.

B at ter y.
The hybrid system features a high-
voltage nickel metal hydride (NiMH) bat-
tery consisting of 240 cells. It provides
the electric machine with the energy required for the vehicle to drive short

distances solely on electric power.
The compact bat tery is located under the
loadspace floor in the luggage compart -
ment. Weighing approximately 80 kg,
its dimensions are 426 mm x 925 mm x
286 mm.
The bat tery is designed to last without
the need for any maintenance throughout
its entire life. As the electric machine
also functions as a generator, it can
charge the bat tery under certain condi -
tions when the combustion engine is in
part-throt tle mode and through energy
recovery during braking. A special bat tery management and cooling system main
-
tains a constant temperature and
protects the battery from overheating.
It also monitors the charge/discharge
processes. As a result, the life of the
bat tery is optimised and its suitabilit y
for everyday use ensured, while offering
a high capacit y: 1.7 kWh.
Systems that are usually dependent on
the output provided by the combustion
engine, such as climate control, power
steering and brake assist, run solely
on electricit y on the Cayenne S Hybrid.
As they do not rely on output from the
engine, these functions remain active
when the car is running in electric mode or when it is ‘coasting’ or gliding along
with the engine turned off.
In summary: despite its six- cylinder
powerplant, the Cayenne S Hybrid offers
performance levels that are comparable
with an eight-cylinder unit – but with
significantly lower fuel consumption. Also
when it comes to hybrid drives, we’ve
taken a completely new path. Hardly
surprising really, with a technology this
convincing.

Six-speed manual gearbox.
The six-speed manual gearbox on the
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 optimum progression
through the gears. As the centre console
rises to meet the dashboard, the gear
lever is close to hand – for an even more
engaging drive.
The standard upshift display in the
instrument cluster helps to reduce fuel
consumption further still. Eight-speed Tiptronic S is also available
as an option on the Cayenne in conjunc
-
tion with the auto start/stop function.
Standard on the Cayenne.
Eight-speed Tiptronic S.
The outstanding feature of the eight-
speed Tiptronic S is a particularly wide
ratio spread. 1st gear is designed for
optimum acceleration when pulling away
and greater performance when tackling
ascents and towing loads in off-road
terrain. Top speed is reached in 6th gear
(in 7th gear on the Cayenne Diesel). The
remaining upper gears are used to lower
the revs at high speed, thereby enhanc -
ing fuel economy and occupant comfort. On the motorway in particular, driving

at low revs will significantly reduce the
noise level inside the vehicle.
In automatic mode, the driver can influ -
ence gearshifts on the Tiptronic S using
the throt tle and brakes alone. Tiptronic S
automatically adapts the gearshift points
for performance driving – equally, if a
more defensive driving st yle is detected,
the system selects a gearshift point that
offers maximum fuel economy. Under
heav y braking, Tiptronic S shifts down to
maximise 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 sports 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 backwards with the index finger and
Tiptronic S shifts down. Either the right
or left-hand switch can be used. The
result: an even more dynamic response
when changing gear.

Intelligent, discreet, responsive.
The ideal travelling companion.
Porsche Traction Management (PTM)
on the Cayenne, Cayenne S,
Cayenne GTS 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 differ -
ential (ABD) and anti-slip regulation (ASR).
Torque is distributed bet ween the front
and rear axles by means of the electron -
ically variable multi-plate clutch. For the
toughest off-road terrain, the differential
can be locked using the PTM control
on the centre console. With the aid of
on-board sensors, the status of the car
is continuously monitored and the front/
rear split is adjusted to match changing
driving conditions. The sensors are used
to measure a range of values, 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 transmit ted to the front
axle by a more positive engagement of
the multi-plate clutch. In addition, ASR
minimises wheel spin. During cornering,
the required level of engine torque is
distributed to the front wheels to ensure
excellent lateral stability.
In conjunction with advanced Porsche
Stabilit y Management (PSM, p. 68), PTM
ensures the perfect distribution of drive
torque for optimum traction in all road
scenarios, whether on long straights,
through tight corners or on surfaces

with different friction coefficients. 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 safet y,
Porsche Traction Management (PTM)
offers exceptional handling and driving
dynamics.Standard on the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.

Porsche Traction Management
(PTM) on the Cayenne Diesel and
Cayenne S Hybrid.
The Cayenne Diesel and Cayenne S
Hybrid feature a permanent all-wheel
drive system with self-locking centre
differential. This provides a standard
torque split of 60 % to the rear and
40 % to the front. If one of the wheels
is about to lose grip, the self-locking
centre differential 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 Cayenne, Cayenne S, Cayenne GTS

and Cayenne Turbo.
On the Cayenne Diesel and Cayenne S
Hybrid, PTM also enables variable distribution of engine torque to the rear
wheels, thereby enhancing steering pre
-
cision and driving dynamics. Specifically,
this means that when entering a corner
at high speed, moderate brake pressure
is applied to the inside rear wheel.
This supports the steering motion of
the car, thereby improving its cornering
dynamics.
Standard on the Cayenne Diesel and
Cayenne S Hybrid.
Downhill assistance.
A standard feature on all 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 centre console. The speed
can be set to bet ween 3 and 30 km/ h.

Shedding weight.
Adding agility, economy and comfort.

Chassis.
Weight reduction.
The axle concept on the Cayenne models
features consistent lightweight con -
struc
tion. The results: enhanced driving
dynamics, lower fuel consumption and
optimum occupant comfort.
Front axle.
The chassis on the Cayenne models
offers a direct response – for a more
rewarding driving experience. The wish -
bones on the subframe-mounted front
suspension with high-mounted upper
arms are in aluminium. This axle design
ensures accurate wheel location, greater
agility and minimal interference on uneven
surfaces. The subframe is secured on
large rubber mountings that reduce road
noise to a minimum.
It is also specially constructed to increase
stability. For enhanced comfort and even
greater active and passive safet y. In the
event of an impact, the subframe deforms
in a predefined manner.
Rear axle.
The rear axle features multi-link suspen -
sion. Ideal for performance road and track
use, it also copes well with the extremely
high towing and carrying loads that are
possible with each Cayenne. The suspen -
sion struts are angled to allow longer
suspension travel and create a deeper and
wider cargo area. As well as providing
additional space, the car is also easier
to
load.
The rear axle design minimises dive and
squat under acceleration and braking.
It also improves mid-corner stability and
compensates for sudden load transfer. In short: it enables a more relaxed

way of driving. Examples of intelligent
lightweight construction on the rear
axle include hollow drive shafts.
Steering.
The steering system has been com pletely
revised and adapted for a more immediate
response and greater driving dynamics.
Around the straight-ahead pos ition, in
particular, the ratio is now more direct.
With the variable steering ratio and spe -
cial valve settings on the power-steering
system, optimum manoeuvrability is
ensured. The turning circle of the Cayenne
models is just 11.9 metres.
The steering column itself consists of
multiple collapsing sections linked by two
universal joints and a special deformation
element provides additional safet y in the
event of a front impact. Electro -hydraulic power steering is

used for the first time on the Cayenne S
Hybrid. The demand-driven pump only
provides assistance to the steering as
and when required, thereby contributing
to overall efficiency.
Power steering Plus.
Power steering Plus is a speed-sensitive
power-steering system.
At higher speeds, the steering becomes
firmer, inputs are more precise and
driver comfort is enhanced. At lower
speeds, it enables easy manoeuvrability
and parking.
Standard on the Cayenne S Hybrid.
Optional for all other Cayenne models.

Air suspension.
The Cayenne models can be equipped
with an air suspension system featuring
self-levelling, ride-height control and
PASM (p. 57)
1) – for enhanced driving
dynamics and comfort. The self-levelling
facility maintains a constant ground
clearance, which can easily be adjusted using the ride-height control on the
centre console.
Air suspension with PASM standard
on the Cayenne Turbo. Optional for all
other Cayenne models.

Steel-spring suspension.
The steel-spring suspension meets
high-level requirements in terms of per
-
formance, driving pleasure and off-road
capability. Consistent lightweight con -
struction – e.g. through the increased
use of aluminium – results in improved
driving dynamics, greater fuel economy
and enhanced comfort. The steel-spring suspension with a 24 mm reduction in
ride height on the Cayenne GTS is
designed to
deliver one thing above
all else: sports performance.
Standard on the Cayenne, Cayenne
Diesel, Cayenne S, Cayenne S Hybrid
and Cayenne GTS.
Porsche Dynamic Chassis Control
(PDCC).
Available as an option in conjunction
with air suspension, Porsche Dynamic
Chassis Control (PDCC) is an active

anti-roll system that further enhances the
extraordinary road holding and precision
handling of the Cayenne models. PDCC
anticipates and significantly reduces
lateral body movement when cornering
with the aid of the active anti-roll bars
featuring hydraulic swivel motors on
the front and rear axles. The system
responds to the current steering angle
and lateral acceleration by producing a
stabilising force that precisely negates
the swaying
force of the body. The bene-
fits are greater agilit y at every speed,
more responsive steering, stable load transfer characteris
tics and enhanced
occupant comfort. When off-road mode
is selected via a switch on the centre
console, this allows the t wo halves of
each anti-roll bar to rotate further in
opposition to each other. This in turn
enables greater wheel articu lation and
ensures that each individual wheel has
more contact with the ground, improving
traction on uneven surfaces.
Optional for the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.
