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?

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.

The engine of the Cayenne Diesel.
The Cayenne Diesel is powered by a
3.0 -litre V6 turbo - diesel engine with
a common-rail injection system. Its
turbocharger features Variable Turbine
Geometry (VTG, p. 42). The incoming
exhaust gases drive a set of electronical -
ly variable turbine blades whose angle is
continuously adjusted to ensure optimum

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.

Air intake system.
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 further enhanced on the V6
engine in the Cayenne and the V8 engine
in the Cayenne S and the Cayenne GTS
by a t wo -stage intake manifold. This vari -
able 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 result: highly impressive torque
ratings across the entire engine speed
range.
Turbocharging system in the
Cayenne Turbo.
In the Cayenne Turbo, the engine is
assisted by t win turbocharger units
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
Cayenne S Hybrid.

The engine in the Cayenne S Hybrid is
equipped with a supercharger. For a
more direct response, even at low revs
and road speeds. The supercharger has
a low-temperature water cooling system
for cooling the charge air.
Variable Turbine Geometry (VTG) in
the Cayenne Diesel.
The turbocharger in the Cayenne Diesel
features Variable Turbine Geometry
(V TG). The gas-flow from the engine
is channelled onto the turbines via elec -
tronically adjustable guide vanes. By
changing the vane angle, the system can
replicate the geometry in all t ypes of
turbo, large or small, and thus achieve
the optimum gas-flow characteristics.
As a result, even at low engine rpm,
the turbine speed is maximised. For a
significant increase in boost pressure,
excellent cylinder charging plus greater
power and torque.
Electronic engine management.
Cultured performance in all driving
scenarios requires comprehensive
engine control. The electronic engine
management system does this by
continually monitoring the relevant input
data from a variet y 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, e.g. ignition and
injection timings as well as injection
quantities, are seamlessly and auto -
matically adjusted. Other major functions
include on-board recuperation. It ensures
that the on-board power supply is only
replenished while the vehicle is on the
overrun. This boosts fuel economy as
well as performance, and ensures max -
imum engine output during acceleration.
All this goes unnoticed by the driver,
apart from the obvious benefits: lower
fuel consumption and CO
2 emissions plus
greater power and torque at all times.
Exhaust system.
The light weight exhaust systems in the
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.
Sports exhaust system.
Available as an option on the Cayenne
and Cayenne S and included as standard
on the Cayenne GTS, the sports exhaust
system
1) provides an even more distinct -
ive sound. For the looks to match, it
comes with a specially designed set of
t win dual-tube tailpipes with a high-gloss
finish. On the Cayenne GTS, these are
finished in mat t black.
All exhaust systems, standard and
sports, comply with the EU 5 emissions
legislation.

The concept behind every car we build
is based around the pursuit of perform -
ance. This has been the case since
1948. Another of our traditional core
values is efficiency. At Porsche, we are
continually striving to find a successful
balance between the two.
This is achieved using advanced engine
concepts featuring technologies such
as DFI (p. 40), VarioCam Plus (p. 39),
the auto start /stop function (p. 38),
the parallel full hybrid drive (p. 28) and
consistent lightweight construction. Weight reduction is a key aspect of our
design philosophy derived from our rich
racing heritage. Part of our R&D Centre,
the Motorsport Department is located in
Weissach where it shares premises with
the Automotive Industry Exhaust Emission
Centre (ADA). Just a
coincidence? We call
it symbiosis.
In practice: the Cayenne is up to 185 kg
lighter, depending on the model.
1) We
have achieved this through the use of
new, innovative weight-saving materials,
the development of new production technologies and functionalities, and a
series of concept modifications. This

has enabled us to halve the weight of
the tailgate, for example. Innovative
materials are also a feature of the axle
construction, with steel being replaced
where possible by lightweight alterna -
tives such as aluminium and plastic.
The benefits for the driver: greater agilit y
and driving dynamics – with lower fuel
consumption. Efficiency at its best.
Great achievements are something to be proud of.
Even more so if they benefit the world around you.

Exhaust emissions.
The Cayenne models are all equipped
with the latest emissions technology. As
a result, they comply with the European
exhaust emissions standard, EU 5.
Whatever the class, every Porsche
combines high performance with com -
paratively moderate emissions. On the
Cayenne models, this is achieved using
advanced drive concepts – from petrol
and diesel engines to our parallel full
hybrid drive. This is further aided by the
rapid warm-up cycle of the catalytic
converters. The optimum operating tem -
perature is reached earlier so emissions
are reduced sooner when starting from
cold. On the petrol- engined and hybrid models,
another important feature is the use of
t win oxygen-sensor circuits. Each bank of
cylinders has a separate control system
which the engine management system
uses to establish the optimum amount of
fuel – for effective emissions control.
The exhaust-gas recirculation on the
Cayenne Diesel routes part of the exhaust
gas back into the combustion process,
resulting in lower peak com bustion tem-
perature and therefore lower nitrogen
oxide emissions. An oxidation catalyst
also forms an integral part of the process
along with a diesel particulate filter.
Porsche engines.
Performing for today – and the future.
Fuel and fuel economy.
Increasing performance while enhancing
fuel economy. The Cayenne comes in a
choice of three different drive systems,
each featuring state-of-the-art technol -
ogy for high efficiency and relatively low
fuel consumption. The petrol-engined
models already operate on fuels with

an ethanol content of up to 10 %. This
further improves the carbon dioxide
balance since the plants grown for the
production of biofuels absorb carbon
dioxide from the atmosphere. As you
can see, for the benefit of the environ
-
ment, we are continually working on
making our cars more efficient – as

well as compatible with alternative
fuels. While ensuring that they remain
one thing: a thoroughbred Porsche.
Fuel system.
We have also applied the highest stand -
ards to our petrol- engined models in
order to protect the environment from
fuel evaporation. The non-return fuel
supply system provides a considerable
reduction in vapour emissions. The lines
carrying vapour are made from multi-
layer plastics. A large active-carbon
filter and multi-layer plastic fuel tank help
reduce evaporation still further.
