The new Cayenne Diesel is power­
ed by a 3.0 ­litre V6 turbo ­diesel
engine with a common ­rail injec ­
tion system. Its turbocharger fea ­
tures Variable Turbine Geometry
(V TG, p. 40). The incoming ex ­
haust gases drive a set of elec ­
tronically variable turbine blades
whose angle is continuously
adjusted to ensure optimum

performance under all engine
loads. This results in an output
of 176 kW (240 hp) and maximum
torque of 550 Nm. The car
accelerates from 0 to 100 km/ h
(62 mph) in 7.8 seconds.
Max
imum torque is available
bet ween 2,000 and 2,250 rpm.
Top speed is 218 km/ h (135 mph),
while fuel consumption has been
lowered by 20 %. On all Cayenne petrol engines,

we have used direct fuel injection
(DFI, p. 38) to achieve a signi fi­
cant increase in specific power
and torque as well as bet ter fuel
economy and lower emissions.

timing on both inlet and exhaust.
The unit delivers 220 kW (300 hp)
at 6,300 rpm and maximum
torque of 400 Nm at 3,000 rpm.
Maximum speed is 230 km/ h
(143 mph). The car requires

7.5 seconds to reach 100 km/ h
(62 mph) with a manual gearbox.
At the same time, fuel economy
has been improved by up to 20 %.

VarioCam Plus.
VarioCam Plus creates t wo en ­
gines out of one by steplessly
adjusting the inlet valve timing
and lift.
The system dif ferentiates
bet ween normal road usage and
performance driving, adapting
seamlessly as driver inputs
change. All functions are auto ­
matically 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 lif t set ting
and retards valve timing.
At medium revs and minimal
load, the valve lif t is lowered and
timing advanced to minimise fuel
consumption and emissions. At
low engine speeds in particular,
VarioCam Plus significantly im ­
proves fuel economy. To achieve maximum power and torque, the
valve lif t is raised and the timing
advanced.
Overall, the system provides
greater performance with rela­
tively modest fuel consumption.
Standard on the new Cayenne S
and new 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 new Cayenne S Hybrid, the
inlet valve timing is continuously
adjusted.
The key benefits include bet ter
fuel economy and lower emis ­
sions. It also helps to generate
greater power and torque –
even at low engine speeds.
Standard on the new Cayenne
and new Cayenne S Hybrid.
The starter motor has been re
­
vised to cope with the additional
demands of the system, and
the bat tery charge and life are
continuously monitored. The
bat tery and starter motor are
replacement parts that are
subject to greater wear and
tear with frequent use of the
auto start /stop function.

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.
Auto start/stop function.
The new Cayenne models that
are equipped with the new eight ­
speed Tiptronic S also feature an
auto start /stop function. If, for
example, you stop at traf fic lights
with your foot on the brake pedal,
the auto start /stop function will
automatically cut the engine.

consistently within a specific
temperature range. The engines
in the new Cayenne models are
therefore designed for optimum
cooling.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20% of coolant flows longi­
tudinally 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. In addition,
thermal management ensures
that the optimum operating tem ­
perature for the engines is
reached more quickly. This keeps emissions and fuel consumption
low, even when starting from cold.
The entire cooling system is
designed for prolonged heav y
­

dut y use, e.g. of f ­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 of f ­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 engine in the Cayenne has
a wet ­sump lubrication system.
Ensuring a reliable supply of oil,
no mat ter how challenging the
driving conditions.
Direct fuel injection on the
diesel engine (common-rail
injection system).
On the Cayenne Diesel, direct
fuel injection comes courtesy of
a common ­rail injection system.
The injection pressure of up
to 1,800 bar ensures optimum
distribution of the air/fuel mixture
– for greater performance. The
piezoelectric injection valves
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
capabilit y over a long service life
if all components are operating
Direct fuel injection (DFI).
DFI injects fuel directly into the
combustion chamber at up to

120 bar with millisecond precision
using electromagnetic injectors.
The injector position and spray
geometry have been carefully
designed to improve output,
torque, fuel economy and emis ­
sions. The swirling of the fuel as
it enters each chamber increases
the mixing of air and fuel, thereby
enhancing combustion. By form ­
ing the air/fuel mixture directly
in the combustion chamber, DFI
contributes to engine cooling.
As a result, it was possible to in ­
crease the compression ratio and
therefore power and efficiency.

Compression with precision.
Essential for getting right to the point.

response, even at low revs and
road speeds. This is particularly
useful when driving in urban
traf fic. The supercharger has a
low­temperature water cooling
system for cooling the charge air.
Variable Turbine Geometry in
the new Cayenne Diesel.
The turbocharger in the new
Cayenne Diesel features Variable
Turbine Geometry (V TG). The
gas ­flow from the engine is
channelled onto the turbines via
electronically 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 sig
­
nificant increase in boost pres ­
sure, excellent cylinder charging
plus greater power and torque.
Electronic engine management.
Cultured performance in all
driving scenarios requires com ­
prehensive 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 com ­
pared with a corresponding set of
reference values. Based on this
information, a range of key engine
functions, e.g. ignition and in­
jection timings as well as injection
quantities, are seamlessly and
automatically adjusted. Other
major functions include automatic
compensation for changes in fuel
qualit y and control of the variable ­
tract intake manifold. On the
new Cayenne Turbo, the engine management system also regu ­
lates the turbo boost pressure.
The results:
optimum fuel eco
n ­
omy and lower CO
2 emissions as
well as greater power and torque
at all times.
Exhaust system.
The light weight exhaust systems
in the new Cayenne models are
made from special, long ­life stain ­
less steel. The key features of
the catalysts are high ef ficiency,
faster warm ­up and a long service
life. The sports exhaust system
1)
available as an option on the
new Cayenne and new Cayenne S
provides an even more distinctive
sound. The package also includes
a specially designed set of t win
dual ­tube tailpipes. All exhaust
systems, standard and sports,
comply with the strict EU5 emis ­
sions legislation.
2)
Turbocharging system in the
new Cayenne Turbo.
In the new Cayenne Turbo, the
engine is assisted by t win turbo ­
charger 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 t win inter­
cooler system, which improves
cylinder charging and limits
thermal loads on the engine.
Supercharging system in the
new Cayenne S Hybrid.
The engine in the new Cayenne S
Hybrid is equipped with a
supercharger. For a more direct
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 ef fect is enhanced in the new
Cayenne and new Cayenne S by
a t wo ­stage intake manifold. This
variable 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.

Off ­road Mode 2 – for even great ­
er traction on dif ficult terrain,
the multi ­plate clutch can be fully
locked.
The electronically variable rear
differential on the optional
Porsche Torque Vectoring Plus
(PT V Plus) is integrated within
the all ­wheel drive system. This
automatically ensures the opti ­mum distribution of drive torque
on particularly uneven surfaces.
If one of the rear wheels begins
to slip, the rear dif ferential varies
the amount of torque transmit ted
through each drive shaf t, thereby
restoring traction. In Of f
­road
Mode 3, the rear dif ferential can
be manually locked using the main
of f ­road control. Then both rear
wheels receive the same amount
of torque, regardless of surface
conditions. The optional PDCC
(p. 53) enables greater wheel
articulation in all three modes,
improving traction still further.
For effective prevention of dam ­
age to the underside of the car,
all new Cayenne models can be
equipped with optional of f ­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.

high­mounted upper arms are now
in aluminium. This axle design
ensures accurate wheel location,
greater agilit y and minimal inter ­
ference 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 stabilit y. 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
suspension. 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 suspension 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 stabilit y and compensates
for sudden load transfer. In short:
it enables a more relaxed way
of driving. Examples of intelligent
light weight construction on the
rear axle include hollow drive
shafts.
Steering.
The steering system has been
completed revised and adapted
for a sportier driving st yle.
Around the straight ­ahead pos­
ition, in particular, the ratio is
now more direct. With the variable
steering ratio and special valve
set tings on the power ­steering
system, optimum manoeuvrabilit y
is ensured. The turning circle of
the new Cayenne models is just
11.9 metres.
The steering column itself
consists of multiple collapsing
sections linked by t wo 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.
Servotronic.
Servotronic 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.
