Hood.
Our engineers have completely redeveloped
the hood for the 911 Carrera Cabriolet
models. The result is a flexible roof
comprising of a glass rear screen and
three individual and integral hood ele -
ments, which are manufactured from
magnesium and covered in fabric. This
makes the hood highly robust and, yet,
particularly lightweight. Another benefit of the new design is

that the hood is smooth and firm. The
fabric remains taut keeping the familiar
911 lines elegant. A trivialit y? Only if
you choose to ignore the impressively
low drag coefficient of just 0.30 that
the new 911 Cabriolet models are able
to achieve. A further feat of Porsche
engineering.
The rear screen is made from glass and
is electrically heated and scratch-
resistant to provide excellent rearward visibilit y. A rain channel on the hood

carries away water to avoid dripping
when the doors are opened.
Electrically powered, the new hood is
operated using a but ton on the centre
console or via the key remote. It opens
or closes in approximately 13 seconds
and remains operable up to a speed
of 50 km/ h (31 mph). The concertina
action ensures optimum protection for
the interior lining. The interior hood lining is made from

a heat-insulating and sound-absorbing
material. Consistent interior temperatures
and an effective suppression of wind
noise are the perceptible results. Thank -
fully, however, even the hood’s sound -
proofing properties are no match for
the resonant Porsche sound.
Open, flexible, independent.
The optimum prerequisites for a long-term relationship.

Wheels.
On the new 911, the wheels have been
enlarged by one inch over the previous
model. Not only do the larger wheels
improve dynamic performance, they
also look more imposing.
The new 911 Carrera models are
equipped with 19-inch Carrera wheels as
standard. These are lightweight
alloys featuring a classic sport y design.
Tyre sizes are 235/40 ZR 19 and
285/35 ZR 19 at the front and rear
respectively.
The S models are equipped with light-
alloy 20 -inch Carrera S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to cope with the increased power output
of these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear.
The larger t yre size improves both ride
comfort and track performance. The

rolling resistance of the t yres
has been
reduced by up to 7 % to improve
fuel
economy, while t yre weight and dry brak -
ing distances have also been reduced. A selection of 20-inch wheels is available in
our range of options.
Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) is available
on request. This safet y system sends
warnings to the on-board computer’s
display screen in the event of low t yre
pressure or a gradual or sudden loss
of pressure. The individual pressures
in all four t yres can be displayed in the
instrument cluster.
Porsche Stability Management (PSM).
As standard, the new 911 models

are equipped with enhanced Porsche
Stabilit y Management (PSM), which
maintains stability even at the limits of
dynamic driving performance. Sensors
continuously monitor the direction,
speed, yaw velocity and lateral acceleration
of the car. Using this information, PSM is able to calculate the actual direction
of travel at any given moment. If the car
begins to oversteer or understeer, PSM
applies selective braking on individual
wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake differential
(ABD) and anti-slip regulation (ASR). When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving st yle.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels)
requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of
driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

From the start, Porsche has been
synonymous with motorsport. Ever since
1948, when we found our identit y on
the racetrack, we have taken the experi -
ence we have gained and applied it to
the road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine example.
This brake system has already had to
cope with the harshest requirements of
Composure | Safet y
motor racing and is fit ted in cars that
compete in demanding events such as
the Porsche Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs for the new 911 have a diameter
of 350 mm front and rear for even more
formidable braking performance.
The use of six-piston aluminium monobloc
brake calipers on the front axle and four-
piston units at the rear – all finished in
yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent. What we’ve discovered from over 28,000 racing victories:
Brake later, finish sooner.

Porsche Ceramic Composite Brake (PCCB).PCCB enables shorter braking distances
in even the toughest road and race
conditions. Excellent fade resistance
ensures greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this
represents a major reduction in unsprung
and rotating masses. The consequence
of this is bet ter road holding and increased comfort, particularly on uneven
roads, as well as greater agilit y and
improved handling.
Please note that circuit racing, track

day use and other forms of performance
driving can significantly reduce the
service life of even the most durable
brake pads and discs.
As with conventional high-performance
braking systems, we recommend that
all brake components be professionally
inspected and replaced where necessary
after every track event.

Electric parking brake.
The new electric parking brake, which
you can activate and deactivate manually,
releases automatically as you pull away.
With the hill-hold function, you can

pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The new 911 models offer advanced
airbag technology in the form of full-size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort to
the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the new 911 models
are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact protec -
tion elements in the doors and t wo air -bags on each side. An integral thorax

airbag is located in each seat side bolster,
while the door panels each contain an
upwards-inflating head airbag. Each
thorax airbag has a volume of 10 litres
and each head airbag 15 litres, ensuring
excellent protection in the event of a
side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera
Cabriolet models have exemplary torsional
rigidit y and flexural strength. Body flexing
is minimal, even on the most poorly sur -
faced roads.
Increased protection is provided by an
automatically deploying roll-over protec -
tion system if the car were to overturn.
Two spring-loaded roll-over bars are
neatly incorporated behind the rear
seats. The roll-over sensor continuously
monitors the car’s pitch and roll, contact
with the road, as well as lateral and
longitudinal forces. If the car were to
overturn, the roll-over bars would be
deployed instantly.

Exterior mirrors and rear-view mirror.
The most prominent new feature of the
electrically adjustable exterior mirrors is
their position. They are mounted directly
on the doors for improved aerodynamics.
Electrically folding exterior mirrors with
courtesy lighting on both sides of the
vehicle are available as an option.

Roof transport system.
Available as an option for the Coupé
models, the new roof transport system in
aluminium is aerodynamically efficient,
very light weight and easy to fit. A range
of at tachments is available, such as a
roof box, a bike carrier or a ski/snowboard
carrier. Maximum roof load is 75 kg.
By illuminating the area in front of the
doors, they make it easier to find your
way in the dark.
An auto-dimming function for the rear-
view mirror and exterior mirrors, with
an integrated rain sensor for the wind -
screen wipers, is available as an option.Slide/tilt sunroof.
The optional electrically adjustable slide/
tilt sunroof for the Coupé models is a
completely new design. It opens out wards
so that it does not interfere with head -
room. Another advantage of the new
design is the much larger aperture for
increased driving pleasure under the
open sky. The newly developed t wo -position net-
t ype wind deflector protects against
draught and further reduces wind noise.
ParkAssist.
Park Assist is fit ted as standard in the
911 Cabriolet models and is available as
an option for the 911 Coupé models.

Featuring four inconspicuous sensors in
the rear end, the system audibly alerts
the driver to the presence of obstacles
detected behind the vehicle. An intermit -tent warning tone increases in rapidity

as the obstacle is approached.
An enhanced version of Park Assist,
with four sensors in the front end, is
available as an option. The audible alert
is supplemented by a visual warning
in the central display screen, which
shows a graphical representation of
the vehicle from overhead.

Words can barely describe the 911 experience.

Sound can.

Burmester
® High-End Surround Sound System.
When t wo iconic German manufacturers
join forces, the result is special. We’re
referring to Porsche and Berlin-based
Burmester
®, one of the most respected
manufacturers of high-end audio equip -
ment worldwide, and the Burmester
®
High-End Surround Sound System.
The technologies behind the system are
based on the finest premium home audio
systems Burmester
® has to offer.
The system owes its eminence to count -
less details, and one goal: perfection
in sound.
The system has 12 amplifier channels
with a total output of more than 821
watts, 12 loudspeakers including an
active subwoofer with 300 -wat t class D amplifier, a total diaphragm surface area
of more than 1,340 cm², and a frequency
response of 35 Hz to 20 kHz.
For the first time in a 911, Burmester
®

has introduced the patented integral
subwoofer, which replaces the familiar
separate subwoofer and loudspeaker
arrangement of other systems. This saves
weight and has a beneficial impact on
acoustic performance.
Crossover technology has been carried
over more or less unmodified from the
home audio sector. Analogue and digital
filters have been optimally defined for
their new installation location and finely
tuned af ter extensive in - car audio testing. The t weeters are ribbon-based air motion
transformers (AMT) that have been
designed specifically for the 911. For
unmistakably fine, clear and undistorted
high-frequency sound reproduction with
excellent level stability. All loudspeaker
housings are perfectly matched and deliver
superior bass foundation, definition and
impulse accuracy. As yet unequalled

in the 911, the result is a natural and
richly textured spatial sound even at

top volume.
The pure, sport y design with galvanised
surrounds and Burmester
® logos on
selected loudspeakers make it clear that
the appeal of the Burmester
® High - End
Surround Sound System is as much about the visual as it is the audio.

Environment
Since 1963, we’ve defined the 911 in terms of sporty performance.
And we’ve scrutinised it daily for its efficiency-enhancing potential.

Porsche and the environment.
We’ve already spoken about our contribu -
tion to motorsport. To be more precise,
about our responsibility for the future of
motorsport. We meet this responsibility
with intelligent technology, unconventional
ideas and optimum performance.
Our approach to environmental protection
is no different. In an era of intensifying
debate about global climate change and
CO
2 emissions, every automotive manu -
facturer is asking what it has to offer
right now. Our answer has long been the
same: excellent performance at the
same time as greater efficiency. Porsche has managed to reduce fuel

consumption across all model ranges
by a double-digit percentage compared
with the respective previous model even
though performance has been increased.
This is made possible by an efficient
drive concept (e.g. DFI and VarioCam
Plus), lightweight construction, optimised
aerodynamics and low rolling resistance.
The environmental management team
at the Porsche Development Centre
in Weissach aims to demonstrate a high
level of environmental responsibility. Here, technological developments are
carried out with environmental protection
in mind. The goal is to enhance perfor
-
mance – but, where possible, not at the
expense of the
environment. We achieve
this goal with
Intelligent Performance, as
epitomised
by the 911.

2 emissions please refer to page 129.
