Everything has changed.
Apart from the concept.
Cayenne.
At Porsche, we are continually changing.
Looking for a new and different approach.
Without ever losing sight of where we’ve
come from. That ’s how we remain true to
ourselves.
The basic Cayenne concept is therefore
the same. We’ve just continued to
improve it: the Cayenne is now lighter –
up to 165 kg
1) depending on the specifi -
cation – and also more dynamic, more
comfortable, and closer to the road than
ever before. Without detracting from the
qualities required for off-road driving or
towing heav y loads.
Its naturally aspirated 3.6-litre V6 engine
features direct fuel injection (DFI, p. 40),
variable valve timing on both inlet and
exhaust, and a variable resonance intake manifold – for a generous output and
excellent fuel economy. In other words:
we have enhanced the performance,
while significantly lowering the weight,
fuel consumption and CO
2 emissions. The
figures speak for themselves: maximum
torque of 400 Nm, 220 kW (300 hp),
a top speed of 230 km/ h and the abilit y
to accelerate from 0 to 100 km/ h in
7.5 seconds. With both fuel consumption
and CO
2 emissions reduced by 20 %.1)
Delivering this power to the road effi -
ciently, Porsche Traction Management
(PTM, p. 47) combines active all-wheel
drive with an electronically variable multi-
plate clutch, automatic brake differential
(ABD, p. 47) and anti-slip regulation (ASR,
p. 47). Together they enable the perfect
distri bution 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
trans mitted through a high-performance


six-speed manual gearbox (p. 44), which
ensures optimum progression through
the gears.
In addition to the standard 18-inch
Cayenne wheels and larger brakes, the
Cayenne can be fit ted with the optional
Porsche Ceramic Composite Brake
(PCCB, p. 66) – for even more outstand -
ing brake performance.
Another key advantage: a total weight
saving of approximately 50 % compared
with equivalent cast-iron discs. The generous standard equipment
includes partial-leather seats, climate
control, the CDR audio system with
touchscreen, cruise control and auto
-
matic headlight activation. For added
comfort, 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 car.
So, a unique blend of the great sports
performance and unrestricted everyday
practicalit y that is t ypical of Porsche.
Let ’s be honest, would you have expected
anything else?

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.

23 · The Cayenne | Cayenne GTS
True, asphalt is rather grey.
But that need not apply to what’s happening on it.
Cayenne GTS.
GTS – three unmistakable let ters which, in
conjunction with the name Porsche, have
writ ten history both on and off the track.
Three letters that combine exceptional
racing performance with superb everyday
agilit y and that, at Porsche, have always
stood for impressive figures.
Good reasons to take a closer look at the
Cayenne GTS. A concept reduced to its
essential elem ents: output, performance,
intelligence. A concept that is true to its
roots: the tarmac – the place where life
happens for purists.
In the Cayenne GTS beats the heart of a
pure-bred athlete that knows only one
direction: straight ahead. The up rated,
naturally aspirated 4.8-litre V8 engine
delivers 309 kW (420 hp) and maximum
torque of 515 Nm. The benchmark sprint
from 0 to 100 km/ h is completed in just 5.7 seconds. Top speed comes in

at 261 km/ h.
The Cayenne GTS is also highly efficient –
thanks to standard fuel-saving technolo -
gies including the auto start/stop function
(p. 38), VarioCam Plus (p. 39) and direct
fuel injection (DFI, p. 40).
The ride height on the steel-spring sports
suspension is 24 mm lower than on the
other Cayenne models – for a lower
centre of gravit y. Also fit ted as standard,
Porsche Active Suspension Management
(PASM, p. 57) is an electronic damping
control system.
The striking central air intake underlines
the sheer power within. The SportDesign
package – standard fitment on the
Cayenne GTS only – includes the following
features in exterior colour: athletic lower front and rear apron elem

ents, dynamic
side skirts, unique wheel arch extensions
and rear spoiler with fixed bi - plane design.
All components have been
optimised
in the Porsche wind
tunnel to improve
their
efficiency and further enhance the
vehicle’s
purposeful stance.
The standard sports exhaust system
delivers an even more distinctive sound.
For the looks to match, it features t win
dual-tube tailpipes with mat t black finish.
St ylish and safe: the Bi-Xenon headlights
with black surround and Porsche Dynamic
Light System (PDLS, p. 63) are fit ted as
standard. The car features the same day -
time running lights as the Cayenne Turbo:
each main headlight unit has four LED
spotlights. The tinted taillights are also
equipped with LED technology. The Cayenne GTS is fit ted with 20 -inch

RS Spyder Design wheels as standard.
These one-part alloy wheels feature a
race-inspired look and brake calipers with
a red paint finish.
Pure sports appeal and exclusivit y con-
tinue inside the Cayenne GTS. The door
panels, armrests, seat centres and roof -
lining are finished in Alcantara. The GTS
sports seats with 8-way adjustment are
highly dynamic thanks to their low posi -
tioning. With adjustable fore/aft,
height
and squab/ backrest angle set tings,
they
also offer exceptional comfort and
sup-
port – even during performance driving.
The Cayenne GTS. Developed so that life
can be enjoyed in its purest form.

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.

The heart of every Porsche.
Applying power with intelligence.
Engine technology.
Auto start/stop function.
The Cayenne models that are equipped
with eight-speed Tiptronic S also feature
an auto start /stop function. If, for ex -
ample, you stop at traffic lights and keep
your foot on the brake pedal, the auto
start/stop function will automatically
cut the engine. Although the engine is
not running, all audio and communication
systems remain switched on and the
standard climate control continues to
maintain the selected temperature. The
only changes you’ll perceive: peace
and quiet and – thanks to greater fuel
economy – also peace of mind.
The system is deactivated in certain
situations, e.g. if the outside temperature
is very high or the bat tery charge is low.
The starter motor has been revised to cope with the additional demands of the
system, and the bat tery charge and life
are continuously monitored. The battery
and starter motor are replacement parts
that are subject to greater wear and tear
with frequent use of the auto start /stop
function.

Standard on the Cayenne Diesel,
Cayenne S, Cayenne S Hybrid,

Cayenne GTS and Cayenne Turbo.
Available as an option for the Cayenne in
conjunction with the optional Tiptronic S.
VarioCam Plus.
VarioCam Plus creates t wo engines out
of one by steplessly adjusting the inlet
valve timing and lift.
The system differentiates bet ween nor
-
mal road usage and performance driving,
adapting seamlessly as driver inputs
change. All functions are automatically
controlled by the engine management
system. All you experience is responsive
acceleration and ultra-smooth running
characteristics. Inlet valve timing is
steplessly adjusted. To improve response
when starting from cold, for example,
VarioCam Plus selects the higher lift
setting and retards valve timing.
At medium revs and minimal load, the
valve lift is lowered and timing advanced
to minimise fuel consumption and emis -
sions. At low engine speeds in particular, VarioCam Plus significantly improves fuel
economy. To achieve maximum power
and torque, the valve lift is raised.
Overall, the system provides greater
performance with relatively modest fuel
consumption.
Standard on the Cayenne S,
Cayenne GTS and Cayenne Turbo.
Variable valve timing.
The V6 engine in the Cayenne features
variable valve timing on both inlet and
exhaust. The camshaft phase angles

are continuously varied by the engine
management system via rotary-vane
adjusters.
On the Cayenne S Hybrid, the inlet valve
timing is continuously adjusted.
VarioCam Plus
The key benefits include better fuel
economy and lower emissions. It also
helps to generate greater power and
torque – even at low engine speeds.

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.
Standard on the Cayenne Diesel,
Cayenne S, Cayenne S Hybrid,

Cayenne GTS and Cayenne Turbo.
Optional for the Cayenne.

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.
