2010 PORSCHE CAYENNE fuel consumption

Standard on the new Cayenne
Diesel, new Cayenne S, new
Cayenne S Hybrid and new

Cayenne Turbo. Available as an
option for the new Cayenne
in conjunction with the optional
Tiptronic S.
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.

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.

Ty r e s .
All t yres have been optimised
with regard to driving perform­
ance, handling, rolling resistance
and weight. They also provide
great potential for reducing fuel
consumption and emissions. The three basic components of
the t yre have been enhanced –
the rubber compound, tread de­
sign and the architecture of the
substructure. This reduces rolling
resistance and fuel consumption.
Tyre Pressure Monitoring
(TPM).
Tyre Pressure Monitoring (TPM)
provides early warning of any
drop in pressure via the on

computer display. In addition, the driver can quickly
and easily check the individual
pressures in all four wheels via
the multi
­purpose display in the
instrument cluster. Standard on the new Cayenne

Weight reduction is a key aspect
of our design philosophy derived
from our rich racing heritage.
Part of our R&D Centre, the
Motorsport Department is locat ­
ed in Weissach where it shares
premises with the Automotive Industry Exhaust Emission Centre
(ADA).
Just a coincidence? We call
it symbiosis.
In practice: the new Cayenne is
up to 185 kg lighter, depending
on the model.
1) This was achieved
through new weight ­saving devel ­
opments and materials, new pro ­
duction technologies, advanced
functionalities and concept
modifications. By using lighter materials, for example, we have
halved the weight of the tailgate.
New materials are also a feature
of the axle construction, with
steel being replaced where pos­
sible by light weight alter
natives
such as aluminium and plastic.
The benefits for the driver:
greater agilit y and driving
dynamics – with lower fuel
consumption. Ef ficiency at
its best.
This is achieved using advanced
engine concepts featuring tech ­
nologies such as DFI (p. 38),
VarioCam Plus (p. 37), the auto
start /stop function (p. 36), the
parallel full hybrid drive and con ­
sistent light weight construction.The concept behind every car we
build is based around the pursuit
of performance. This has been
the case since 1948. Another
of our traditional core values
is efficiency. At Porsche, we

are continually striving to find a
successful balance bet ween
the t wo.
Great achievements are something to be proud of.
Even more so if they benefit the world around you.
Environment.

has a separate control system
which the engine management
system uses to establish the
optimum amount of fuel – for
effective emissions control.
The exhaust­gas recirculation on
the Cayenne Diesel routes part
of the exhaust gas back into the
combustion process, resulting
in lower peak combustion tempera ­
ture
and therefore lower nitrogen
oxide emissions. An oxidation
catalyst also forms an integral part of the process along with

a diesel particulate filter. This
ensures that the new Cayenne
Diesel meets the EU5 emissions
standard.
Fuel and fuel economy.
Increasing performance while
enhancing fuel economy. The
new Cayenne comes in a choice
of three dif ferent drive systems
each featuring state ­of ­the ­art
technology for high ef ficiency and
relatively low fuel consumption.
The petrol ­engined models
already operate on fuels with an
ethanol content of up to 10%. The diesel engine is compatible
with a biodiesel blend of max. 7%.
This further improves the carbon
dioxide balance since the plants
grown for the production of
biofuels absorb carbon dioxide
from the atmosphere. As you
can see, for the benefit of the
environment, we are continually
working on making our cars more
ef ficient – as well as compatible
with alternative fuels. While
ensuring that they remain one
thing: a thoroughbred Porsche.
Fuel system.
We have also applied the highest
standards in order to protect
the environment from fuel
evaporation. The non ­return

fuel supply system provides a
considerable reduction in vapour
emissions. The lines carrying
vapour are made from multi ­layer
plastics. A large active ­carbon
filter and multi ­layer plastic fuel
tank help reduce evaporation still

advanced drive concepts –
from petrol and diesel engines to
our new parallel full hybrid drive.
This is further aided by the rapid
warm ­up cycle of the cataly tic
converters. The optimum operat ­
ing temperature is reached earlier
so emissions are reduced sooner
when starting from cold.
On the petrol ­engined and hybrid
models, another important feature
is the use of t win oxygen ­sensor
circuits. Each bank of cylinders Exhaust emissions.
The new Cayenne models are
all equipped with the latest emis ­
sions technology. As a result,
they comply with the stringent
European exhaust emissions
standard, EU5.
Whatever the class, every Porsche
combines high performance
with comparatively moderate
emissions. On the Cayenne
models, this is achieved using
Porsche engines.
Performing for today – and the future.
