Drive
The convenience of an automatic.
The excitement of a sequential gearbox.
Six-speed Tiptronic S.
Each gearshift point is automatically
selected based on current road
conditions and driving style.
Within a short space of time,
you’ll develop a feel for the
system and begin to influence
gearshifts using the throttle alone.
The benefits of Tiptronic S are most
apparent in high-performance driving.
The immediacy of response, with
practically no interruption in drive,
is comparable with that of a manual
gearbox.
Tiptronic S automatically selects
the optimum gearshift pattern,
even in low-range mode. The
low-range gearing is available at
speeds of up to 15 km / h (9 mph).
You can also return to high-range
mode at up to 30 km / h (19 mph).
For complete manual control,
simply slot into manual and use
the gearshift controls on the
steering wheel. If you prefer, you
can use the gear selector lever
on the centre console. Even in
automatic mode, you can change
gear manually via the rocker
controls on the steering wheel.
If there is no further manual
input for a period of 8 seconds,
the system reverts to automatic
mode.
One of the special features in
Tiptronic S is standby control.
When the car is stationary in an
active gear position and with the
foot brake applied, the input
clutch automatically disconnects
the engine from the driveline,
thereby reducing fuel consumption.
Other useful functions include
a warm-up programme which
temporarily suppresses upshifts
in order to accelerate warm-up
in the catalysts and thus reduce
emissions. If rapid throttle inputs
are detected, the system automat-
ically selects the ‘Sport’ gearshift
pattern, i.e., there is no need to
use a ‘kickdown’ function. When
the throttle is released quickly, e.g.,
on entering a corner, unwanted
downshifts are prevented.
Mid-corner gearshifts are also
suppressed, enhancing stability
and safety.Under heavy braking, Tiptronic S
shifts down to maximise engine
braking. An incline sensor enables
better uphill acceleration and
better engine braking on descent.
Another special feature, Porsche
Hill Holder, permits easy hill starts
without the need to use the brakes.
The gearbox cooling system is
specifically designed to match
the performance, transport,
towing and off-road capabilities
of all Cayenne models.
Tiptronic S is standard equipment
on the Cayenne Turbo and optional
on the other three models. The
six forward ratios transmit power
with smoothness, efficiency and
precision – whatever your choice
of terrain.
In automatic mode, the gearshift
maps range from maximum
economy to maximum performance.

Off road
Applying power with sensitivity, protecting with strength.
Off-road Technology package.
The rear differential enables
optimum distribution of engine
torque in difficult off-road terrain.
A fully automated part of the
all-wheel system, its primary
function is to optimise traction.
If one of the rear wheels begins
to lose grip, the differential varies
the torque transmitted through
each drive shaft, thereby restoring
traction. Available as a factory-fitted
option on all Cayenne models, the
Off-road Technology package*
incorporates an electronically
variable and lockable rear
differential as part of the standard
all-wheel drive system. Other
features include high-strength
rock-rails with integrated skid
plates, a reinforced engine-bay
guard, enhanced protection for
the fuel tank and rear axle, and
a second towing lug.In low-range mode, the rear
differential can be manually
locked using the main off-road
control on the centre console.
In this state, both rear wheels
receive the same amount of
torque.
For additional off-road protection,
optional wheel-arch extensions
(black finish) and running boards*
with integrated skid plates are
available.
* Not available for the Cayenne GTS.

The secret of performance?
Efficiency.
OBD II on-board diagnostics. The
key components, however, are the
primary and secondary catalytic
converters on the twin exhaust
tracts. Each catalyst has a rapid
warm-up cycle so emissions are
which the engine management
system uses to establish the
optimum air/fuel mix and monitor
the efficiency of the catalytic
converters.

(Cayenne and Cayenne Turbo)
and LEV2 – ULEV (Cayenne S
and Cayenne GTS) regulations

the class, every Porsche
combines high performance
Exhaust emissions.
The Cayenne models are all
equipped with the very latest
emissions technologies. As a
result, they comply with both the
stringent EU4 exhaust emissions
with only moderate emissions.
On the Cayenne models, this is
achieved using an advanced
engine concept featuring direct
fuel injection, VarioCam Plus
(V8 engines) or variable valve
timing (V6 Cayenne) as well asreduced sooner when starting
from cold.
Another important feature is
the use of twin oxygen-sensor
circuits. Each bank of cylinders
has a separate control system

Environment
Fuel system.
We have also applied the highest
engineering standards to protect
the environment from fuel
evaporation. The non-return
fuel supply system provides a
considerable reduction in vapour
emissions. The fuel lines are
partly constructed from steel,
while those carrying vapour are
made from multi-layer plastics.
A large active-carbon filter and
multi-layer plastic fuel tank help
reduce evaporation even more.
A leak detection pump is also
included to monitor the integrity
of the fuel tank system.
Acoustics.
Think of a Porsche and what
do you hear? One of the most
distinctive sounds on the road.
A sound created not just by the
engine, but also by the absence
of unwanted noise. To minimise
Fuel economy.
At Porsche, we’re using innovative
technologies to increase perform-
ance while enhancing fuel economy.
With direct fuel injection (DFI),
we’ve made our engines more
efficient in terms of both output
and consumption. DFI is combined
with VarioCam Plus in the V8 engines
and variable valve timing in the
Cayenne V6. As well as improving
performance and economy, both
of these systems help to minimise
engine emissions. The low-drag
exterior on each Cayenne model
further improves efficiency.
Fuel.
All Porsche models are already
compatible with a fuel ethanol
content of up to 10 %. Ethanol
has a positive impact on the carbon
dioxide balance since the plants
grown for its production absorb
carbon dioxide from the atmosphere.
‘play’ between engine components
under all load conditions, we’ve
used stronger, lighter and more
temperature-resistant materials.
This reduces mechanical noise
and eliminates the need for engine
encapsulation. Large-volume
silencers and air intake manifolds
also help to minimise noise –
throughout the life of the car.
Tyre noise has been drastically
reduced in collaboration with
our official tyre partners. Wind
noise levels have also been
lowered thanks to aerodynamic
refinements.
All that remains is the Porsche
sound – as legendary as ever.

Environment
Servicing.
Although every journey is a pleasure
in a Porsche, there’s one you won’t
have to make too often. Thanks to
the lengthy service intervals and
long-life components, we may not
be seeing you for some time.
In the case of the oil filter, for
example, all that’s replaced is an
easily recyclable paper element.
The oil filter casing remains on
the car.
All moving parts inside the engine
are fully self-adjusting. The valve
clearances, for example, feature
automatic hydraulic control.
All camshafts have a zero-
maintenance chain-drive system.With single-spark coils on each
of the cylinders, the entire ignition
system, with the exception of the
spark plugs, is maintenance-free.
These modest servicing require-
ments mean less waste disposal
and fewer demands on natural
resources. They also lower the
cost of ownership while keeping
your car on the road.
Service intervals for the Cayenne
models are dependent on a range
of factors, including local fuel
quality. For full details of service
intervals in your country/region,
please consult the relevant price
list or contact your Porsche Centre.
Materials and recycling.
Owning a Porsche should be a
lasting pleasure with minimal
impact on the environment. That’s
why every Porsche is built to
endure both technically and in
terms of design. The lightweight
exhaust on the Cayenne models,
for example, is constructed from
long-life stainless steel.
Weight reduction is a fundamental
part of the Porsche design philoso-
phy. By using a greater proportion
of high-strength materials, e.g.,
special steels, cast aluminium
alloys and synthetic materials, we
have successfully reduced the
weight of each car and therefore
its fuel consumption. Every produc-
tion process we use at Porsche
is designed with the environment
in mind. Also, every Porsche model
is
entirely free of asbestos, CFCs
and
components manufacturedusing
CFCs. All legal requirements
in respect of recycling are fulfilled.
Materials are labelled in accordance
with VDA 260, enabling better
recycling of end-of-life vehicles and
individual parts and assemblies.
While more than 85 % of the car
can be recycled using current
technologies, the chances are
your new Cayenne may never need
recycling at all. After all, two thirds
of all the cars we have ever made
are still on the road today.
