ESP PORSCHE CAYNNE 2013 2.G Information Manual

We’ve been building sports cars for more
than 60 years. During that time, we’ve
brought race-proven technologies to the
road – and
great emotion to ordinary
everyday driving.
Yet the Cayenne is any thing but
ordinary – especially in the SUV
segment. We’ve also continued to
drive forward the Cayenne concept.
The result: a car that brings us closer
to the fascinating appeal of the sports
car than ever before. With higher
performance, typical Porsche design
genes and an interior that delivers
true sports car appeal.
The Cayenne. To the point.The Cayenne

Those who develop talent reap the reward.
Sometimes in more ways than one.
The Cayenne models.
When we launched the first Cayenne in
2002, it was met with great scepticism.
Can it still be considered a Porsche at
all? Our reply: never before in the history
of the company, had a model gone
from 0 to 100,000 sold units so quickly.
The second-generation Cayenne too has
firmly established itself in the SUV
market, demonstrating that exceptional
sports car performance is not just
restricted to the road, while the first
Cayenne Diesel proved once more
that we are not afraid to follow uncon -
ventional paths.
The success story continued to gather
momentum in 2010 – with the sum of the
ideas inherent in every Porsche. Innovative drive systems have led to
greater efficiency: fuel consumption has
been reduced by up to 23
% and CO
2
emissions by up to 26 %. This was
achieved thanks to the Cayenne models
being considerably lighter, with each
one weighing up to 185 kg less than the
respective previous model. They also
feature a host of advanced technologies
such as the auto start/stop function
(p. 38). All this has made our vehicles
more dynamic, practical and comfortable
than ever before.
For increased comfort and safet y there’s
a range of driver assistance systems
including the optional adaptive cruise
control (p. 110) with Porsche Active Safe
(PAS). Ensuring a phenomenal sound
experience in every seat position is the
optional Burmester
® High-End Surround
Sound System (p. 96). The most innovative – and therefore in
keeping with the rest of the Porsche
family – is the Cayenne S Hybrid. Its par
-
allel full hybrid system (p. 28) harnesses
the power of an electric machine (motor/
generator) and an internal combustion
engine. This provides several clear
benefits for the driver: outstanding
sports car performance combined with
excellent fuel economy. Once again,
typically Porsche.
The Cayenne Diesel is no exception.
The drive system is based on the tried-
and-tested Porsche principle. We’ve
just refined the concept, making it even
lighter and more powerful.
The Cayenne and Cayenne S offer
increased power and efficiency, while
also delivering exceptional capability
off road. The result: greater driving pleasure with reduced fuel consumption
and CO
2 emissions. On and off road.

This has also been achieved through the
use of advanced technologies such as
direct fuel injection (DFI, p. 40), eight-
speed Tiptronic S (p. 44) and VarioCam
Plus (p. 39). The interaction bet ween
all components has also been optimised.
The Cayenne GTS: an SUV descended
from a thoroughbred sports car. The
purist among Cayenne models, it is
extremely close to the road. With excep -
tional performance, a reduction in ride
height and an engine note t ypical of the
GTS, it offers one thing above all else:
pure sporting prowess.
Another of our principles: high per -
formance should never come at the
expense of comfort or safet y, and

this is something we have kept to. Even
with a car offering the phenomenal out -
put of the Cayenne Turbo. Its 4.8-litre V8
powerplant develops 368 kW (500 hp),
which is guaranteed to set pulse rates
climbing and send a shiver down the
spine – both natural reactions in a turbo -
charged Porsche.
Standard active safety features include
Bi-Xenon main headlights with the
Porsche Dynamic Light System (PDLS,
p. 63). For greater comfort and perform -
ance, the car is equipped as standard
with eight-speed Tiptronic S (p. 44), while
Porsche Torque Vectoring Plus (PTV Plus,
p. 56) enhances driving dynamics and
stability.
As always, we’ve focused on what ’s really
important. To the point: the Cayenne
models.

Drive systems and chassis
How could we make the Cayenne more
powerful and yet, at the same time,
more efficient? Where should we start?
It ’s obvious, really. 1948 – where else?
That’s when the values that we hold
so dearly today – and will continue to
do so in the future – were established.

After all, is there any thing wrong with
having progressive concepts, social
responsibility and a clear direction?

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.

Compression with precision.
Essential for getting right to the point.
Direct fuel injection (DFI).
DFI injects fuel directly into the combus -
tion chamber at up to 120 bar with milli -
second precision using electromagnetic
injectors. The injector position and spray
geometry have been carefully designed
to improve output, torque, fuel economy
and emissions. The swirling of the fuel as
it enters each chamber increases the
mixing of air and fuel, thereby enhancing
combustion. By forming the air/fuel mix -
ture directly in the combustion chamber,
DFI contributes to engine cooling. As a
result, it was possible to increase the
compression ratio and therefore power
and efficiency.
Direct fuel injection on the diesel
engine (common-rail injection system).
On the Cayenne Diesel, direct fuel injec -
tion comes courtesy of a common-rail
injection system. The injection pressure
is now up to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture – for
greater performance. The piezoelectric
injectors provide flexible injection rate
adjustment, using exactly metered
quantities of fuel, with multiple injections
for each power stroke to deliver smooth
combustion.
Cooling systems.
A high-performance engine can only
maintain its maximum capability over
a long service life if all components are
operating consistently within a specific
temperature range. The engines in the
Cayenne models are therefore designed
for efficient cooling.
In order to reduce the frictional losses
that occur during warm-up, all Cayenne
models feature comprehensive thermal
management. Using intelligent control,
it activates the different cooling circuits
individually and on demand, thereby
ensuring that the optimum operating
temperature for the engine and trans -
mission is reached more quickly. This
minimises friction – and keeps fuel
consumption and CO
2 emissions low.
The V8 engines have an enhanced coolant
management system offering effective
temperature control throughout the engine.
While 20 % of coolant flows longitudinally
through the crankcase, the remaining 80 %
serves the cylinder heads using the proven
cross-flow principle (from hot to cold).
On all Cayenne models, the piston heads
are cooled using oil-spray jets integrated
within the main lubrication system.
The entire cooling system is designed for
prolonged heav y-dut y use, e.g. off-road
driving or heav y towing and carrying
applications.
Lubrication.
The V8 engines use dry-sump lubrication
to ensure a consistent supply of oil in
all load conditions, especially in off-road
terrain. The oil reservoir is located inside
the engine. This saves on space and
reduces weight.
Oil is circulated around the V8 engines
using a demand-driven pump. This has
been designed for the toughest driving
scenarios on and off road, including per -
formance driving and extreme gradients.
The V6 engines have a wet-sump lubrica -
tion system. Ensuring a reliable supply of
oil, whatever the driving conditions.

2 emissions and efficiency class data, please refer to pages 150/151.

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.

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.

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.
