Luggage compartment.
In addition to the loadspace in the
rear seat area, the new 911 Turbo
has a 105-litre front luggage
compartment. The bulkhead
panelling conceals the standard
audio amplifier for the BOSE
®
Surround Sound System, as well
as the DVD drive for the
navigation module. The optional
CD autochanger is installed on the
right-hand side of the compartment
(looking forwards). The entire
compartment is lined with high-
quality, scratch-resistant
materials.
Roof transport system.
The optional roof transport
system is made from lightweight
aluminium, making it extremely
easy to fit. It is also styled to
match the exterior design as well
as the car’s aerodynamics. The
basic load-carrying bars can
be
combined with a range of
attachments from Porsche
Tequipment, including a roof box
and carriers for bikes, snowboards
and skis. Maximum roof load is
75 kg.
Anti-theft protection.
Standard anti-theft equipment
on the new 911 Turbo includes
an engine immobiliser with in-key
transponder. The comprehensive
alarm system features contact-
sensitive exterior protection and
radar-based interior surveillance.
Vehicle tracking system.
Optional protection includes a
factory-fitted preparation enabling
future installation of a vehicle
tracking system from Porsche
Tequipment. In the event of theft,
the system enables remote
tracking of the stolen vehicle
across most European countries.
Also requires special wiring
loom and higher capacity battery.

The BOSE®Surround Sound
System has a unique acoustic
presence. Just like the new
911 Turbo. Which is why we chose
to develop them together as a
single, integrated whole.
The standard BOSE®Surround
Sound System in the new
911 Turbo has a nominal output
of 325 Watts. Power is supplied
by a seven-channel MOST
®-based
digital amplifier, featuring
5 x 25-Watt linear amps and
2 x 100-Watt switching units.
MOST®(Media Orientated
Systems Transport) is a
fibre-optic bus network offering
fast data transfer and perfect
signal quality.
A total of 13 loudspeakers,
including active subwoofer and
centerfill speaker, create a unique
sound at all four seat positions
that complements the driving
experience. The balanced, lifelike
and crystal-clear sound is
the product of numerous audio
technologies.
BOSE
®Surround Sound uses
independent channels at front and
rear to create a push-button
panorama of space and sound.
Adding to this experience is
the patented BOSE
®Centerpoint®
technology, which can split
even stereo recordings into five
separate channels. These are
then passed to selected speakers
with the aid of BOSE®
SurroundStage™ signal
processing.
acoustics of the new 911 Turbo.
The dynamic loudness function
offers a considerable
improvement over conventional
loudness circuitry. By enhancing
the lower frequencies in low-
volume sound, it actively
compensates for the reduced
sensitivity of the human ear at
the lower end of the audio
spectrum. Another important
feature of the BOSE
®Surround
Sound System is AudioPilot
®
Noise Compensation Technology.
Using a microphone in the
dashboard, AudioPilot®monitors
the sound in the cockpit and
automatically compensates forany ambient noise. The result is
a clearer and more consistent
sound, with no need for manual
adjustment.
BOSE®and Porsche: two
legendary sounds, perfectly
matched in the new 911 Turbo.

At Porsche, we’re exploring every
possibility to improve the environ-
mental compatibility of our cars:
modern materials, reduced fuel
consumption, cleaner emissions,
fewer pollutants and better
recyclability. This commitment is a
Porsche tradition that began in
the 1960s. With the latest evolutionof the 911 Turbo, the rewards are
even greater than ever.
Exhaust emission control.
Combine engineering expertise
with a commitment to the
environment and the resulting
benefits are twofold: exceptional
performance and lower emissions.
One of the cleanest sportscars
in the world today, the new
911 Turbo easily complies with
both the stringent Euro 4 standard
in the European Union as well
as LEV II regulations in the United
States.The technologies used to achieve
this compliance include twin
‘lambda’ or oxygen sensors for
each of the two cylinder banks.
One pair of sensors is used to
measure the levels of oxygen in
each of the twin exhaust tracts.
An additional pair of sensors –
again, one in each tract – enablethe engine management system
to monitor the efficiency of the
catalytic converters.*
Recycling.
Lightweight construction, long-
term durability, exceptional
recyclability: just three of the
techniques employed by Porsche
to improve the environmental
compatibility of our cars.
On the new 911 Turbo, we’ve
used weight-saving design and
lightweight materials to achieve
excellent fuel economy.
All materials and manufacturing
processes have been carefully
selected and specifically refined
to reduce any impact on the
environment. A prime example is
the twin exhaust system, which is
made entirely from stainless steel.
All lightweight materials are easily
recyclable, while the variety ofsynthetics has been significantly
reduced. Recycled plastics are
used in every area of the car
where our exacting specifications
allow. To simplify processing, all
materials are labelled for separate
recycling. Approximately 85 % of
today’s 911 Turbo is compatible
with current recycling techniques.
Water-based paints are used
throughout the car, thus reducing
the need for chemical solvents in
both production and subsequent
servicing. Other harmful materials
omitted from the vehicle include
asbestos, CFCs, and components
manufactured using CFCs.
The result is a car in which
environmental protection is an
integral part of the overall design.

Environment
* Not in markets with leaded fuel.
The 911 Turbo is dedicated to performance.
Also with respect to the environment.

Servicing.
Longer service intervals are not
only easier on resources, they
also reduce ownership costs. The
new 911 Turbo has very modest
servicing requirements of 18,000
miles or every two years (standard
service) and 36,000 miles or
every four years (major service).
The replacement intervals for
parts and fluids have also been
significantly extended: engine
oil and filter every 18,000 miles,
air filter every 36,000 miles,
spark plugs every 36,000 miles
or four years, and fuel filter every
56,000 miles.
Noise.
The new 911 Turbo complies with
all noise regulations worldwide.
Instead of resorting to engineencapsulation, we’ve eliminated
noise at source: engine com-
ponents are more rigid, moving
parts are lighter, and tolerances
have been reduced to a minimum.
High-efficiency silencers in durable
stainless steel help to minimise
noise throughout the life of the
car. All that remains, both inside
and out, is the famous Porsche
sound.
Fuel system.
Key developments in the fuel
supply system include a further
reduction in the evaporation of
hydrocarbons. This is achieved
through a combination of active
carbon filter and specially coated
fuel tank. All fuel lines are made
from robust aluminium, while
those carrying vapours use multi-
layer plastic.

From our hands to yours.
Where better to experience the
first moments with your Porsche
than at the home of Porsche
engineering.
Almost 60 years ago, our first
large-scale production models
were crafted by hand in a modest
red-brick building, here in
Zuffenhausen. From those humble
beginnings, the factory has
evolved into one of the most
advanced production facilities in
the world. Today, it’s home to anew generation of legends: the
911, the Boxster, the Cayman S
and, of course, your Porsche.
Our factory collection programme
offers a unique insight into
the origins and making of your
Porsche. Like your car, a visit to
Zuffenhausen is an absorbing mix
of past and future, history and
innovation, heritage and creativity.
To take advantage of this exclusive
opportunity, please inform your
Porsche Centre when you place
your specification. A collection
date can then be arranged when
final information regarding the
build of your car has been
confirmed. Your Porsche can be

The factory tour is one of our
oldest traditions, and is usually
conducted by a retired member
of staff. Each of our guides is
a genuine Porsche enthusiast

takes around one-and-a-half
hours to complete, and follows
delivery of your Porsche. The keys
will be presented by a member
of the Factory Collection Team
who will explain everything you
need to know about the car.
You can now take your place
behind the wheel, and experience
what it means to drive your
own Porsche. For the perfect
introduction to the pleasure
of Porsche ownership,* you may
wish to combine your visit with
