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.

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.

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

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.
