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.
For fuel consumption, CO
2 emissions and efficiency class data, please refer to pages 150/151.

Drive systems and chassis | Engine technology · 44
43 · Drive systems and chassis | Engine technology
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.

Transmission.
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.

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.

Air suspension.
The Cayenne models can be equipped
with an air suspension system featuring
self-levelling, ride-height control and
PASM (p. 57)
1) – for enhanced driving
dynamics and comfort. The self-levelling
facility maintains a constant ground
clearance, which can easily be adjusted using the ride-height control on the
centre console.
Air suspension with PASM standard
on the Cayenne Turbo. Optional for all
other Cayenne models.

Steel-spring suspension.
The steel-spring suspension meets
high-level requirements in terms of per
-
formance, driving pleasure and off-road
capability. Consistent lightweight con -
struction – e.g. through the increased
use of aluminium – results in improved
driving dynamics, greater fuel economy
and enhanced comfort. The steel-spring suspension with a 24 mm reduction in
ride height on the Cayenne GTS is
designed to
deliver one thing above
all else: sports performance.
Standard on the Cayenne, Cayenne
Diesel, Cayenne S, Cayenne S Hybrid
and Cayenne GTS.
Porsche Dynamic Chassis Control
(PDCC).
Available as an option in conjunction
with air suspension, Porsche Dynamic
Chassis Control (PDCC) is an active

anti-roll system that further enhances the
extraordinary road holding and precision
handling of the Cayenne models. PDCC
anticipates and significantly reduces
lateral body movement when cornering
with the aid of the active anti-roll bars
featuring hydraulic swivel motors on
the front and rear axles. The system
responds to the current steering angle
and lateral acceleration by producing a
stabilising force that precisely negates
the swaying
force of the body. The bene-
fits are greater agilit y at every speed,
more responsive steering, stable load transfer characteris
tics and enhanced
occupant comfort. When off-road mode
is selected via a switch on the centre
console, this allows the t wo halves of
each anti-roll bar to rotate further in
opposition to each other. This in turn
enables greater wheel articu lation and
ensures that each individual wheel has
more contact with the ground, improving
traction on uneven surfaces.
Optional for the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.
