Porsche Doppelkupplung (PDK).
Available as an option for all 911 Carrera
models is 7­speed PDK, featuring manu ­
al and automatic modes. It facili
tates
extremely fast gear changes
with no
interruption in the flow of power, whilst at
the same time improving acceleration
and fuel efficiency. In total, PDK has seven gears at its dis
­
posal. Gears 1 to 6 have a sports ratio
and top speed is reached in 6th gear.
7th
gear has a long ratio and helps to

reduce fuel consumption by keeping
engine revs low.
PDK is essentially t wo gearboxes in one
and thus requires t wo clutches. This
double ­clutch arrangement provides an
Porsche Doppelkupplung (PDK)
alternating, non ­positive connection
bet ween the t wo half gearboxes and the
engine by means of t wo separate input
shafts.
The flow of power from the engine is
transmit ted through one half gearbox and
one clutch at a time, while the next gear
is preselected in the second half gearbox. During a gear change, therefore, one
clutch simply opens and the other closes
at the same time, enabling gear changes
to take place within milliseconds.The effect is instant. Driving feels even
sportier and more dynamic, and agility

is increased. Depending on the gearshift
programme (SPORT button activated
Temperament | Transmission
or deactivated), the gear change is opti ­
mised for comfort or for sport y driving.
With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport ­derived gearshif t strategy’
functions (p. 67).
Coasting.
The ‘coasting’ function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent deceler ­
ation caused by engine braking. In this
way, optimum use is made of the vehi ­
cle’s momentum, allowing it to coast for
longer distances.
For example, you may want to slow down
from 62 mph to 49 mph in anticipation
of the change of speed limit ahead. As
soon as you release the accelerator
pedal, PDK deselects the current gear auto
matically and you begin to coast
in neutral until you have reached your
desired speed. The moment you engage
the accelerator or brake pedal, PDK
selects the appropriate gear smoothly
and seamlessly within a fraction of a
second. In short, driving in coasting mode makes
a real impact on fuel consumption without
any need for compromise on comfort or
sporty performance.
Another way to reduce fuel consumption is
to utilise the coasting function on downhill
gradients that are gentle enough for you

to maintain a constant speed. Efficient on
long journeys, such as on the motorway,
PDK remains ready to respond as swiftly
and precisely as you would expect.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second,
a vehicle weight saving of up to 65 kg
primarily as a result of the intelligent
lightweight construction. To meet the second requirement, we
employed state
­of­ the ­art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
­
partment and luggage compartment lids.
Magnesium, which is a particularly light ­
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models, the
hood shell elements. Such material effi ­ciency is key to reducing the overall
weight and, as a result, fuel consumption
of the vehicle.
For the driver, this intelligent blend

of materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration ­damping
characteristics and particularly high com ­
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The longer wheelbase improves comfort
as well as straight ­line accuracy and
driving stabilit y at high speeds and in
fast corners.

Front and rear axles.
The independent suspension at the front
features a light weight spring ­strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn
­in.
The rear axle is equipped with a
motorsport ­derived multi ­link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Wheels.
The 911 Carrera models are equipped
with 19­inch Carrera wheels as standard.
These are light weight 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. All ­wheel ­
drive models are fit ted with even wider
295/35 ZR 19 t yres at the rear. The S models are equipped with light
­
alloy 20­inch 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. All ­wheel ­
drive models have 305/30 ZR 20 t yres
at the rear.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and t yre
weight are all comparatively low, thereby
helping to reduce fuel consumption.
A selection of 20 ­inch wheels is available
in our range of options.Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) is avail­
able 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 911 Carrera models are
equipped with enhanced Porsche Stability
Management (PSM), which maintains sta ­
bilit y even at the limits of dynamic driving
performance. Sensors continuously moni­
tor the direction, speed, yaw velocit y 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 911 Carrera have a diame ­
ter of 350 mm front and rear for even
more formidable braking performance. What we’ve discovered from over 30,000 racing victories:
Brake later, finish sooner.

Porsche Ceramic Composite Brake (PCCB).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.
PCCB enables shorter braking distances
in even the toughest road and race condi ­
tions. Excellent fade resistance ensures
greater balance when slowing from race ­
track speeds.
The key advantage of PCCB is the extreme ­
ly 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 mass
­
es. The consequence of this is bet ter
road holding and increased comfort, par ­
ticularly on uneven roads, as well as
greater agility 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.

2 emissions, please refer to pages 143/145.

Responsibility

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.

Exhaust emission control.
Vehicles manufactured by Porsche dem ­
onstrate that even high ­performance
sports cars can achieve moderate fuel
consumption and exhaust emission val ­
ues in their respective category.
This is achieved, on the one hand, through
the use of fuel ­ef ficient technologies such
as auto start /stop, thermal management,
electrical system recuperation, direct fuel
injection, VarioCam Plus and, in conjunction
with optional PDK, coasting mode.
On the other hand, new cataly tic convert ­
ers developed for the 911 provide efficient
emission control.
The stereo Lambda control circuitry con ­
trols and monitors each cylinder bank
separately. For each exhaust tract, oxy ­
gen sensors regulate the composition of the exhaust gas, while another Lambda
sensor on each cylinder bank monitors
pollutant conversion in the respective

cataly tic converter.

Fuel economy and recycling.
Intelligent light weight construction has
been fundamental to the Porsche identit y
since 1948, for both technical and eco ­
logical reasons. This forms the basis for
achieving low fuel consumption values in
conjunction with outstanding perfor ­
mance.
On the technical side, we use a high
proportion of aluminium, magnesium,
plastics and super ­high ­strength sheet
steel. The materials used have been
selected for their ability to withstand
load, yet they are considerably lighter
than conventional steel.
On the ecological side, all materials used
are meticulously selected. All synthetic
components are easily recyclable and each
material is labelled to facilitate its separa
­
tion for recycling. The reduction in the
number of plastic variants helps to ensure
more ef ficient recycling. Recycled plastics

are used where they meet our exacting
technical requirements.
In short, the 911 is around 95 % recyclable.
In addition, Porsche uses a high propor ­
tion of environmentally friendly water ­
based paints. For us, environmental
protection does not begin at the end of
a vehicle’s life. It starts at the planning
and development stage.

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 CO
2
balance since the plants grown for the
production of this biofuel also absorb
CO
2 from the atmosphere.
The release of hydrocarbons from the
fuel system has been minimised thanks,
in no small part, to the active carbon
filter and the multilayered material from
which the fuel tank is made. All fuel lines
are made from multilayered plastic, steel
or aluminium.

2 emissions, please refer to pages 143/145.
