Integrated dry-sump lubrication.
Integrated dry
-sump lubrication ensures
a reliable supply of oil even when a
sport y driving st yle is adopted. It also
has additional cooling functions.
The oil tank is located in the engine,
thereby eliminating the need for an
external oil tank, which saves both space
and weight. To reduce power loss and
increase efficiency, an electronically
controlled oil pump supplies the lubricat -
ing points inside the engine as and
when required. When demand is low, the
oil pump is operated at reduced power,
thereby saving fuel.
Air intake system.
The resonance intake system increases
the intake volume by exploiting the fact
that air oscillates as it passes through
the intake manifold. The system can
adjust to engine speed. Benefits of this
include higher torque at low engine
speeds and a flat ter torque curve. The
911 Carrera S models operate a t wo -
stage system.
The entire intake system is made from
light weight plastic. In the 911 Carrera
models, the resonator volume of the air
filter housing varies with engine speed to
bring added character to the engine
sound, which becomes much more
powerful at higher rpm.
Exhaust system.
The exhaust system of the 911 Carrera
models is a concept that delivers a clear
statement, not only in terms of
acoustics.
The stainless steel exhaust system com-
prises two distinctive and independent
exhaust tracts. The cataly tic converters
heat up rapidly for effective emissions
reduction.
A selectable t wo -tract sports exhaust
system featuring distinctive polished
stainless steel tailpipes is available as
an option. Activated by a but ton, it
produces an even more intensive sports
car sound.
Engine management system.
The EMS SDI 9.1 engine management
system ensures optimum engine perfor -
mance at all times. It controls, for
example, the position of the electronic
throt tle valve (ETC) – a prerequisite for
compatibility with the Porsche Stability
Management (PSM), which comes as
standard. It also regulates all engine -
related functions to achieve optimum
fuel consumption, emissions and power
output whatever the driving st yle.
Another function is the cylinder -specific
knock control. Since the cylinders never
all work under exactly the same condi -
tions, the knock control function monitors
each one separately. The ignition point
is shifted individually, as and when
necessary, to protect the cylinders and
pistons at high engine speeds.
For compliance with EU standards, the
on -board diagnostics detect any faults
and defects that may occur in the exhaust
and fuel systems and then notify the
driver immediately. This also prevents
increased pollutant emissions and
unnecessary fuel consumption.

Porsche Doppelkupplung (PDK).
Available as an option for all
911
Carrera models is 7-speed PDK,
featuring manual and automatic modes.
It facilitates extremely fast gear changes
with no interruption in the flow of power,
whilst at the same time improving
acceleration and fuel efficiency. The first six gears are particularly
sport y, with top speed being reached

in 6th gear. 7th gear has a long
ratio and reduces the revs – for lower
consumption.
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
T emperament | 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 gearshift
strategy’ functions (pages 65– 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
deceleration caused by engine braking.
In this way, optimum use is made of the
vehicle’s momentum, allowing it to coast
for longer distances.
For example, you may want to slow down
from 100 to 80 km/ h in anticipation
of the change of speed limit ahead. As
soon as you release the accelerator
pedal, PDK deselects the current gear automatically 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.

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.

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
low vehicle weight 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 efficiency 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
composite rigidit y, a high degree of
dynamic torsional stiffness, and
especially sporty handling.
The long wheelbase improves comfort as
well as straight-line accuracy and driving
stabilit y at high speeds and in fast
corners.

Hood.
To our engineers, clever and innovative
hood technology is particularly
important. The result we see today is
a flexible fabric hood comprising a fixed
glass rear screen and three integral hood
elements, which are manufactured from
magnesium. This makes the hood highly
robust and, yet, particularly light weight.
Another benefit 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. In the case of the 911 Carrera Cabriolet
models, for example, it ’s as low as 0.30.
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 hood is
operated using a but ton on the centre
console or via the key remote. It opens
or closes in just 13 seconds and remains
operable up to a speed of 50 km/ h. 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.

Electrically powered wind deflector.
Once again, our engineers have gone
their own way – this time in the wind
tunnel. The 911
Carrera Cabriolet models
are equipped as standard with an
electrically powered wind deflector,
which offers practically draught-free driving and minimal wind noise with the
top down.
With the 911, fit ting and removing the
wind deflector is unnecessary because

it is integrated directly into the body
behind the rear seats. As a result, it
doesn’t take up any extra space in the interior or luggage compartment and is
ready for use at all times.
For unrestricted open
-top driving pleasure,
the wind deflector extends or retracts
in just t wo seconds and can be operated
at speeds of up to 120 km/ h.

PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension
is lowered by 10 mm.
PASM has t wo modes, which can be
selected using a separate but ton on
the centre console: ‘Normal’, which is a
blend of performance and comfort, and
‘Sport ’ where the setup is much firmer. To ensure efficient control interventions,
a multitude of sensors in the 911 record
the body movements that accompany
powerful acceleration, braking or uneven
road surfaces. The PASM control unit
evaluates the driving conditions and
modifies the damping force on each of
the wheels in accordance with the
selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer
rating, thereby improving contact bet ween the wheels and the road.

When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is selected
and the driver’s st yle becomes more
assertive, PASM automatically switches
to a harder rating. Damping firms up,
and driving stabilit y and road safet y are
increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The PASM sports suspension is available
as an option for the 911 Carrera Coupé
models in conjunction with 20-inch
wheels and Porsche Torque Vectoring
(PT V) or Porsche Torque Vectoring Plus
(PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti-roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler
extends even further. These not only further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even

better performance.

With the optional Porsche Dynamic
Chassis Control (PDCC) for the S models
of the 911 Carrera, these characteristics
can be further accentuated: the vehicle
holds the road even bet ter and delivers
even sportier performance. PDCC is an active anti-
roll system that
suppresses lateral body movement during
cornering manoeuvres. In addition, it
minimises the lateral instability of the
vehicle on uneven ground. This effect is achieved with the aid of
hydraulic stabilising actuators in the form
of cylinders designed to optimise camber.
Lateral roll is counteracted by forces
generated at each individual wheel, based
on steering angle and lateral acceleration.
Rapid cornering in the 911 Carrera without PDCC (illustrative example) Rapid cornering in the 911 Carrera S with PDCC (illustrative example)
The results are improved dynamic
performance and increased ride comfort
at all speeds, as well as optimised turn-in
and stable load transfer characteristics.
In simple terms, the t yres and vehicle
hold the road bet ter and you can steer
through corners faster and in a more
relaxed manner.
PDCC sets standards for handling
performance, ride comfort and driving
pleasure. In the 911, your ‘usual’ way
suddenly becomes the Porsche way.

It ’s easy, and even makes sense, to carry
on in your usual way, but what happens
if a sudden change of direction leaves
you thrown off course? Then, it all comes
down to personal strength.
A Porsche has a clear sense of purpose
and is the embodiment of strength. It
demonstrates this with sport y and precise
handling and excellent roadholding.
You appreciate directness.
But love a few twists and turns.

Porsche Dynamic Chassis Control (PDCC).

| Chassis and body
On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the 911 Carrera S models,
optional Porsche Dynamic Chassis
Control (PDCC) switch to a harder
damping set ting and offer more direct
steering and, therefore, better
roadholding. In SPORT PLUS mode, the trigger
threshold for PSM is raised. Agilit y is
perceptibly enhanced when braking for
corners with PSM, allowing sportier
braking and exit acceleration. For even
greater dexterit y, PSM can be set to
standby while the car is still in
SPORT PLUS mode. For safet y, it is
set to intervene automatically only

when ABS assistance is required on both
the front wheels.
In combination with PDK, the Sport
Chrono Package has t wo additional
functions for a sport y drive that borders
on a motorsport experience. The first is ‘Launch Control’, which can be used

on the track to achieve the best
possible standing start – a racing start.
The second function is the ‘motorsport-
derived gearshift strategy’. Using this,
Porsche Doppelkupplung (PDK) is geared
up for extremely short shift times and optimum shift points for the maximum
acceleration available. This combination
of uncompromising and involving perfor-

mance is ideal for the racetrack.
A key component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with
optional PCM, a special performance
display enables you to view, store and
evaluate lap times or other driving times.
It shows the total driving time, lap
distance, lap number and lap times
recorded so far.
A feature of the Sport Chrono Package
borrowed from motorsport is the dynamic
engine mounts. These exploit the laws
of physics for your own driving pleasure.
Dynamic engine mounts.
You don’t have to take the 911 onto the
racetrack. But you can, more so than
ever, because dynamic engine mounts
are now included as part of the Sport
Chrono Package.
The electronically controlled system
minimises the oscillations and vibrations
of the entire drivetrain, especially
the engine, and combines the benefits
of a hard or soft engine mounting
arrangement.
A hard engine mounting delivers optimum
dynamic performance because it offers
the highest degree of handling precision
possible. Soft engine mounts, on the
other hand, minimise oscillations and
vibrations. While comfort is improved on
uneven road surfaces, this comes at
the expense of dynamic performance. Our engineers have solved this problem
by enabling the engine mounts to adapt
their stiffness and damping properties to
changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in
interaction with an electrically generated
field. For the driver, the results are tangi-

ble. Handling is perceptibly more stable
under load change conditions and in
fast corners. Whenever a less assertive
driving st yle is adopted, the dynamic
engine mounts provide a higher level of
comfor t.

Telephone module.
The optional quadband GSM telephone
module offers convenience and excellent
reception. With a SIM inserted directly
into the integral SIM card reader of
CDR Plus or PCM, calls can be made
using the hands-free facilit y. For even
more convenience, the Bluetooth
®
capabilit y of a mobile phone can be used
to make calls via the SIM Access Profile
(SAP). Once the connection has been
established automatically, the mobile
phone’s aerial is switched off to conserve
battery charge and the phone operates
via the car aerial. Depending on the mobile phone model, this gives access
not only to the numbers on the SIM card,
but also to the phone’s internal memory.
Depending on the phone, it can also be
controlled using CDR Plus, PCM, the
optional multifunction steering wheel or
the optional voice control system, without
it ever leaving your pocket.
The telephone module also enables you to
establish a Bluetooth
® link with those
mobile phones that support only the
Handsfree Profile (HFP). In this case, the
GSM connection is always established
through the aerial of the mobile phone.
CDR Plus or PCM acts as a hands-free
system and you can leave the mobile
phone tucked away.
On request, a Bluetooth

The sound of a Porsche is a unique
characteristic, and we’re not referring
only to the engine. The optional BOSE
®
Surround Sound System was specially
developed for the 911 and is therefore
perfectly tuned to the car’s specific
