Efficiency-enhancing technologies.
Auto start /stop switches off the engine
when the driving speed falls below 4 mph
under moderate deceleration, such as
when you are approaching a red light. As
soon as you release the clutch or, with
PDK, depress the accelerator pedal, the
engine restarts – swiftly and smoothly.
In conjunction with Porsche Doppelkupplung
(PDK), a coasting function becomes
available where the situation allows.
The engine is decoupled from the
transmission to avoid deceleration
caused by engine braking. In this way,
optimum use is made of the vehicle’s
momentum, enabling it to coast for
longer distances.
Sports exhaust system.
It ’s a first for any Porsche turbocharged
boxer engines, and it ’s a technical
innovation. Available as an option for the
new 911, the sports exhaust system
features t wo cataly tic converters and a
rear silencer, which lead into two centrally
positioned tailpipes. For a look otherwise
more likely to be seen on the racetrack.
For impressive resonance and an intense
sports car sound – typical of the 911.
For 100 % Porsche. And for goose bumps
at the push of a but ton.

Wheels.
T h e 911 Carrera models and the
911
Targa 4 are equipped with 19-inch
wheels. These are lightweight alloys
featuring a classic sport y design. All S models are equipped with 20 -inch
alloy wheels. The visual effect is sport y
and dynamic. The t yres are wider to
cope with the increased power output of
these models.
The large wheel size improves traction
and track performance. Rolling resistance

and t yre weight are comparatively low,
which helps to reduce fuel consumption. A selection of 20 -inch wheels is available
in our range of options.

Electromechanical power steering.
Statistically, a car drives in a straight line
90 % of the time. In light of this, our
engineers identified potential for energy
savings. Unlike the hydraulic pumps of
conventional power steering systems, the
electric motor of the electromechanical
arrangement uses energy only when the
steering wheel is actually turned.
That isn’t to say that you aren’t ideally
prepared for the other 10 %. After all,
this steering system is t ypically Porsche.
It features a variable steering ratio and responds sensitively and directly while
providing customary agilit y, a high level
of comfort and precisely selected
feedback from the road. Our definition

of efficient.

We want to speed everything up. Progress
included. The same applies to negative
acceleration. That’s because even brakes
are a source of potential. So we’ve upsized
the brake system of the new 911 to match
the increased power output.
T h e 911
Carrera base models are fit ted
with newly developed four-piston
aluminium monobloc fixed calipers with
a black anodised finish. All brake discs
have a diameter of 330 mm.
The S models are equipped with red six-
piston aluminium monobloc fixed brake
calipers at the front and four-piston equivalents at the rear. The brake
chambers at the front axle are now
made from aluminium. Brake disc
diameters are 350 mm at the front,
330 mm at the rear. For enhanced
stability and braking performance.
On all models, the brake calipers have an
enclosed monobloc construction. This
makes them tougher but light weight and
enables a more rapid response and
release of the brake even under extreme
loads. The pedal travel is short and the
biting point precise. The brake discs are
cross-drilled for improved wet braking
and optimum cooling.
Porsche Ceramic Composite Brake
(PCCB).
Proven in motorsport, the Porsche
Ceramic Composite Brake (PCCB) is
available as an option. On the new 911,
the cross-drilled ceramic brake discs of
PCCB now have a diameter of 410 mm at
the front and 390 mm at the rear –
for even more formidable braking
performance.
Originating from the 911
 Turbo S, PCCB
features six-piston aluminium monobloc
fixed brake calipers on the front axle and
four-piston units at the rear – all painted
in yellow – to provide braking forces that
are considerably more powerful and,
crucially, are exceptionally consistent.
For Ferry Porsche, even then standing still was unthinkable.
With one exception.
Brakes.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Safety under high-speed
braking is also improved thanks to its
excellent fade resistance.
Another advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of a
similar design and size. This results in
better roadholding and increased comfort,
particularly on uneven roads, as well as
greater agilit y and a further improvement
in handling.

A rest yling of the Bi-Xenon main
headlights – fit ted as standard – sees
the four-spot LED day time running lights
now incorporated into each headlight
unit. These are an innovative technical
feature of the new 911
models – and
a facet of their personality. After all,
it is the characteristic lighting design
that makes the face of the 911
so
unmistakable.
Cut ting edge LED technology is also
used for all functions of the redesigned
taillights. As well as being a powerful
lighting source, LEDs offer a fast response
to driver input. The LED brake lights
emulate the four-spot appearance of the
daytime running lights.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System (PDLS)
is available as an option. Its dynamic
cornering light function swivels the main
headlights towards the inside of a bend,
based on steering angle and road speed,
so as to light up more of the road at
bends and turns. Put simply, the road
ahead is illuminated the moment you
start to corner. PDLS also features
speed-sensitive headlight range control
and the adverse weather function.
LED main headlights including Porsche
Dynamic Light System Plus (PDLS Plus).
Superior safety meets sporty design in
the form of optional LED main headlights
including PDLS Plus. In addition to being
efficient and long-lasting, LED technology
also creates a light very similar to daylight
and thus helps to reduce driver fatigue.
One special feature of PDLS Plus is the
dynamic main beam function. A camera
detects the lights of vehicles ahead as
well as those of oncoming traffic. Based
on the data from the camera, the dynamic
main beam function then adapts the

headlight range accordingly. This
continuous, seamless control means
that you are able to see the course of

hazards earlier without hindering other
road users.

Safety and environment 75
In an era of intensifying debate about
global climate change and CO2 emissions,
every automotive manufacturer is asking
what it has to offer right now. Our
answer? Excellent performance together
with excellent efficiency.
Emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission
values in their respective category.
This is accomplished, on the one hand,
with the efficient use of fuel by means of
efficiency-enhancing technologies such
as auto start /stop, thermal management, electrical system recuperation, active air
intake flaps and, in conjunction with
Porsche Doppelkupplung (PDK), coasting
mode. On the other hand, cataly tic
converters with stereo Lambda control
circuits provide efficient emission
control. Fuel economy and recycling.
Intelligent lightweight construction is
integral to the Porsche identit y. This
is expressed in the form of a high
proportion of aluminium, magnesium,
plastics and super-high-strength
sheet steels. All materials have been
strategically selected, and the paints
used are predominantly environmentally
friendly water-based paints. Each lightweight material is easily recyclable
and all plastic components are labelled
to facilitate future separation for
recycling. In all, the 911
is up to 95
%
recoverable.
Fuel.
All Porsche models – including the 911 –
are designed to operate on fuels with an
ethanol content of up to 10 %, e.g. ‘E10’.
Ethanol has a positive impact on the CO2
balance because it is derived from plants
that absorb CO
2 from the atmosphere.
For others, it’s the order of the day.
For us, the order of the future.

Comfort 81
Sports steering wheel.
Fit ted as standard, the sports steering
wheel with spoked design is light weight
and functional. The small centre pad and
the chrome ring encircling the Porsche
Crest – both derived from the steering
wheel of the 918 Spyder – reinforce its
sporty character.
In conjunction with PDK, the sports
steering wheel features two alloyed
gearshift paddles. The shift throw of the
paddles has been reduced, gearshifts
are even crisper. Available as an option
is the new GT sports steering wheel. This
has a smaller diameter. The decorative
ring and the paddles are finished in
Galvano Silver, while the spoke trims are
screw-fastened. For a motorsport-derived
design? Definitely. Above all, though, to
emulate a motorsport driving feel.
Heating and multifunction controls are optionally available for all steering wheels.
These give you fingertip access to the
colour display, the on-board computer
and many audio, telephone and navigation
functions.

Light design package.
The optional light design package is both
practical and aesthetically appealing. It
comprises dimmable LEDs in the overhead
console and in the areas of the door
handles, door storage compartments,
front foot wells and rear seats.
Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your
pocket. As soon as you grab the door
handle, or your hand nears the Porsche
Crest on the luggage compartment lid, the system automatically checks the
encrypted access code on the key. Once
the key is validated, the door or the
luggage compartment lid unlocks. The
engine can then be started and switched
off using the electronic ignition switch.

Comfort 85
Climate control.
All models feature two-zone automatic
climate control as standard, offering an
enhanced ventilation effect and separate
temperature controls for the driver and
front passenger.
An active carbon filter traps particles,
pollen and odours and an automatic air-
recirculation function permanently
monitors air quality, reduces humidity
and switches from fresh to recirculated
air when required. A demister function
keeps the windows clear in cold weather.
In warmer weather, strong sunlight is detected by a solar sensor, for which the
air conditioning system automatically
compensates in order to maintain the
comfort of both the driver and front
p a s s e n g e r.
Slide/tilt sunroof.
The electrically adjustable slide/tilt
sunroof is available as an option for the
911
Coupé models. It opens out wards so
that it does not interfere with headroom.
Another advantage of this innovative
design is the particularly large aperture for increased driving pleasure under the
open sky. The net-t ype wind deflector
protects against draught and further
reduces wind noise.
Slide/tilt glass sunroof.
On request, the electrically adjustable
slide/tilt sunroof is available in tinted
toughened safet y glass. An integral
electric roll-up sunblind provides shade
from unwanted bright light. The build,
headroom and aperture specifications of
the glass sunroof are otherwise identical
to those of the regular slide/tilt sunroof.
A fresh wind blowing through the sports car segment

has some decidedly pleasant side effects.
