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?

The only thing running low on long journeys:
fuel consumption.
Cayenne Diesel.
Boasting outstanding performance and
efficiency, the Cayenne Diesel is ideal for
longer journeys – offering high levels of
torque, while fuel consumption remains
low.
Its 3.0 -litre V6 turbo - diesel engine is now
more powerful and refined, and approxi -
mately 20 kg lighter.
1) The unit generates
180 kW (245 hp) and maximum torque
of 550 Nm. The sprint to 100 km/ h
requires just 7.6 seconds. Top speed is
220 km/ h. Fuel consumption now comes
in at just 7.2 l/100 km in the combined
test cycle.
2)
Direct fuel injection comes courtesy
of a common-rail injection system.
The piezoelectric injectors enable mul -
tiple injections at a pressure of up to 2,000 bar, ensuring optimum distribution
of the air/fuel mixture – for improved
dynamics.
The turbocharger on the Cayenne Diesel
features Variable Turbine Geometry

(V TG, p. 42). Combined with optimised
channelling of the intake air, it enhances
the charging effect, thereby generating
a higher output and impressive torque,
even at low engine speeds.
The standard eight-speed Tiptronic S
includes gearshift controls on the steer -
ing wheel. Transmit ting the high torque
of the Cayenne Diesel smoothly and
effectively, the eight gears are designed
to facilitate both economical driving with
low fuel consumption and performance
driving with emphatic acceleration. Porsche Traction Management (PTM,
p. 47)
permanent all-wheel drive with
self- locking centre differential transmits
the car’s power to all four wheels with
optimum precision and control.
Available as a no - cost option, the
100 -litre fuel tank increases the range
to well over 1,000 km while keeping
the engine rpm and noise levels low.
The Cayenne Diesel: proof that
a 100 -metre sprinter can also run
a marathon.

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.

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.

From urban jungle to the windy wilds.
The Cayenne is perfectly at home on any terrain.
Off-road capability.
Steep ascents leading to snow- covered
mountain lodges, boggy ground or
muddy, loose surfaces – all situations
that the Cayenne handles superbly with
intelligent all-wheel drive. The drive
systems featured on the Cayenne models
deliver exceptional torque. For plent y of
power on tap. On any terrain.
Operating concept.
With the help of Porsche Traction
Management (PTM), the Cayenne can
cope with even the most demanding
off-road scenarios. Simply move the
main off-road control on the centre

console forward or backward to select
one of up to three off-road modes
(depending on the model). Available
on the Cayenne, Cayenne Diesel,
Cayenne S, Cayenne GTS and Cayenne
Turbo, this
function readies the car for
off-road use or reverts the set ting to
normal road driving.
In Off-road Mode 1, for example, the
maps for all relevant systems, e.g. ABS,
are adapted to provide optimum traction.
In addition, High Level I is selected
on vehicles featuring air suspension
with PASM. If that ’s not enough, the air
suspension can be raised further to
High Level II to increase the approach/
departure angle and wading depth.
1)
Push the off-road control forward again
on the Cayenne, Cayenne S, Cayenne GTS
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 diffe
r-
ential on the optional Porsche Torque
Vectoring Plus (PT V Plus, p. 56) is inte -
grated within the all-wheel drive system.
This automatically ensures the optimum
distribution of drive torque on particular -
ly uneven surfaces. If one of the rear
wheels begins to slip, the rear differential
varies the amount of torque transmit ted
through each drive shaft, thereby restor -
ing traction. In Off-road Mode 3, the rear
differential can be manually locked using
the main off-road control. Then both
rear wheels receive the same amount of
torque, regardless of surface conditions.
The optional PDCC (p. 55) enables greater wheel articulation in all three
modes, improving traction still further.
For effective prevention of damage to the
underside of the car, all 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.
1) The Cayenne GTS has a steel -spring spor ts suspension with a 24 mm reduction in ride height (20 mm reduction with optional air suspension). This will lead to restricted capabilit y when driving of f road.

Making headway without getting in a spin.
An approach we thoroughly support.
Porsche Torque Vectoring Plus
(PTV Plus).
A system for enhancing driving dynamics
and stability, PTV Plus offers variable
distribution of engine torque to the rear
wheels and electronically controlled rear
differential. Depending on the steering
angle, steering speed, throttle pedal
position, yaw velocit y and vehicle speed,
PT V Plus optimises steering response
and precision by applying brake pres -
sure to the left or right rear wheel, as
r equired. Specifically, this means that when enter
-
ing a corner at high speed, moderate
brake pressure is applied to the inside
rear wheel. This transfers drive torque to
the outside rear wheel which supports
the steering motion of the car, thereby
improving its cornering dynamics.
At slow and medium speeds, PT V Plus
considerably enhances agility and steer -
ing precision. At high speeds, during
fast cornering and under wheel spin, the
electronically controlled rear differential
ensures additional stabilit y. Also on
variable-grip surfaces, in the wet and on snow, PT V Plus – combined with Porsche
Traction Management (PTM, p. 47) and Porsche Stabilit y Management (PSM, p. 68)
– provides a major contribution to active
safety.
In off-road terrain, PT V Plus reduces
wheel spin on the rear wheels – even when towing heav y trailer loads. The
electronically controlled rear differential
can be fully locked using the off-road
control on the centre console.
Optional for the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.
Porsche Active Suspension

Management (PASM).
PASM is an electronic damping control
system. It offers continuous adjustment
of individual damping forces based on
current road conditions and driving st yle.
During performance driving or heav y off-
road use, there is an increased tendency
for the body to sway. PASM prevents
this from happening, thereby improving
stability and occupant comfort. PASM
has three setup modes: ‘Comfort ’,
‘Normal’ and ‘Sport’.
Porsche Torque Vectoring Plus (PTV Plus)
Whichever one you select, the system
uses a series of sensors to monitor the
movement of the body. It also gathers
data on lateral acceleration, steering
angle, brake pressure and engine torque
and modifies the damping force on each
individual wheel in accordance with the
selected mode.
PASM remains active at all times. It
automatically adapts to the prevailing
driving conditions, enabling greater
car control and improving comfort and
safety.The Cayenne GTS is the only model in the
range to feature a steel-spring suspension

with a 24 mm reduction in ride height
including PASM. For a lower centre of
gravit y and even closer contact with the
road.
Optional for the Cayenne, Cayenne
Diesel, Cayenne S, Cayenne S Hybrid.
Standard on the Cayenne GTS.

Standard on the Cayenne Turbo:
air suspension with PASM.
