against stone chips.
Elegantly matched to the exterior
of the car is the all-new wheel
design. The 19-inch forged alloys
have a standard two-tone finish
as well as wide, low-profile tyres.
The standard tyre dimensions
are 235/35 ZR 19 (front) and
305/30 ZR 19 (rear).
The interior of the car is equally
compelling and entirely designed
around the driver. The high-quality
surfaces include a full leather
finish on the standard electric
seats as well as the dashboard,
doors and rear side panels. Two
sports seat options are also
available, one featuring adaptive
adjustment. The standard
equipment package includes a

The new 911 Turbo
The extreme capability of the new
911 Turbo is elegantly enclosed in
a highly distinctive exterior. While
signalling the unique athleticism of
the car, it remains unmistakably 911.
The aerodynamics are exceptionally
well balanced, with positive
downforce at the rear. The drag
coefficient is remarkably low
at just 0.31. With its streamlined
shape and lightweight build,
the new 911 Turbo offers excellent
fuel economy as well as super-
lative performance.The standard Bi-Xenon headlights
with integral cleaning system
are compact, stylish and elegantly
incorporated within the new
front-end design. The front apron
moulding is an entirely new
development, featuring high-
performance LED indicators in
the outer air intake ducts. The
compact front foglights are
neatly positioned on the outer
edges of the front apron.
The side air intakes, to the rear
of the doors, provide optimum air
delivery to the twin intercoolerunits. Equally efficient are the
cooling air ducts to the front and
rear brake assemblies. This
enhanced cooling action is an
important factor in the excellent
performance of the standard
braking system.
The body of the car is much wider
across the rear than the front. A
generous wheel track is combined
with wider tyres to achieve
enormous lateral grip. The engine
lid is another totally new design
and features an integral bi-plane
rear spoiler. The
upper wing
element is automatically
raised at
approximately 120 km / h (75 mph)
and lowered at around 60 km / h
(37 mph).
The rear apron moulding has also
been redesigned to blend with
the rest of the car. The side air
outlets and fully enclosed twin
tailpipes are a further indication of
the power within. Black plastic

wheel featuring 40 mm of height

The overall design of the
new 911 Turbo marks another
new phase in the ongoing
evolution of this remarkable car.
Wholly integral to the fundamental
vehicle concept, every detail
is a direct expression of power,
composure and comfort.

Complementing the front airbags
is the latest generation of Porsche
Side Impact Protection (POSIP).
This comprehensive package
includes two additional airbags for
each front seat: a thorax airbag
in the side of each backrest,
and a head airbag located in each
door. Each side airbag has anapproximate volume of 8 litres,
ensuring maximum protection
over the entire seat adjustment
range. Also incorporated within
the POSIP package are side-
impact protection beams in the
doors.Other standard features include
integral head restraints, an
energy-absorbing steering column,
height-adjustable three-point seat
belts with pre-tensioners and
force limiters, energy-absorbing
structures in the dashboard area
and flame-retardant materials
throughout the interior. The new 911 Turbo has a unique
passive protection system
featuring six separate airbags.
The full-size front airbags for
driver and front passenger have
a two-stage inflation capability.
With this technology, the
deployment of each airbag is
dependent on the force and
nature of the accident (e.g.,
frontal or diagonal impact). In
a low-speed crash, the airbag
is only partially inflated, thereby
minimising discomfort to the
occupants.
The airbag control unit is located
in the centre tunnel where it
receives additional information
from a pair of impact sensors near
the headlights. This arrangement
enables faster and more accurate
evaluation of impact forces in the
event of a crash.

Porsche Communication

comprehensive system features
satellite navigation with a
separate DVD drive in the
luggage compartment for
the single navigation disc.
The one-touch switches on the
centre console are logically
positioned for optimum ease of
use. All instruments are perfectly
placed within the driver’s field of
vision. The air-conditioning system
is fully automatic and features a
highly effective active carbon filter.
This added convenience gives
you greater freedom to enjoy the
driving experience.
The tinted front glass and generous
rear screen offer excellent fore-
and-aft visibility. The front side
windows have a water-repellent
finish, which automatically
disperses moisture and dirt.
The result: optimum visibility in
poor weather conditions.
Instruments.
The classic arrangement of five
round instruments provides a
clear overview of all key information.
The digital display in the centre-left
dial (speedometer) provides main
and trip odometer readings. The
central rev counter, featuring the
‘turbo’ logo, includes the standard
on-board computer display.
This multi-purpose field contains a
permanent digital speedometer
as well as the following optional
information: boost pressure,
average speed, average fuel
consumption, tyre pressure,
current radio station, navigation
instructions and remaining range
till empty. When ‘Sport’ mode
is selected on the optional Sport
Chrono Package Turbo, the
temporary increase in torque is
clearly indicated using an arrow
symbol in the boost pressure
display. The third display, in the
centre-right dial, contains a
clock and external temperature.
The dot-matrix technology used in
each of these displays provides
a high resolution for icons and
text. Design and legibility are
further enhanced with brilliant
white backlight illumination.

Interior.
For the pure enjoyment of performance.
The passenger compartment in the
new 911 Turbo is another example
of uncompromising design. As you
would expect, it offers the highest
standards of ergonomics, comfort
and quality. The seats, dashboard,
doors and rear side panels are
finished in leather as standard. Atthe centre of the cockpit is a new
gear lever design that’s exclusive
to the new 911 Turbo.
Other standard features include
a three-spoke sports steering
wheel offering 40 mm of
adjustment for both height and
reach. A three-spoke multi-function
steering wheel – available as

greater headroom, and a
dedicated spring system that
is specifically designed to
match the car’s suspension
characteristics. The high side
bolsters provide excellent lateral
support, without restricting
occupant comfort. The generous
range of adjustment options

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.
