Many legends look to the past.
This one looks to the future.

The new 911.
At the beginning, we took time to reflect
on where we came from and, above all,
where we want to be.
One thing was clear. To be able to build
the new 911, we would need to find the
right answers. What is it that defines us?
The engineering credentials as suggested
by the ‘Dr. Ing.’ in our company name,
certainly. More than 28,000 racing victo -
ries, definitely. Not just feats of heroism
any longer, but responsibilit y for the future
of the sports car and for the environment.
Then there is our reputation as an iconic
sports car manufacturer. However, this
reputation means nothing unless we con -
tinue to breathe new life into old ideas. For us, heritage and future are inseparably
linked. Of course, we could simply have
made a capable sports car, but this wouldn’t
have been a Porsche, and certainly not
a 9 11 .
Our identit y is the 911. This is especially
true, even in the 21st century. Instantly
recognisable and originally engineered
for the racetrack, it continues to stir the
emotions today, just as it did in 1963.
Yet, is that enough to move forward?
Above all, is it enough for you? Don’t we
need to break the stranglehold of tradition
once in a while before it one day stifles
innovation altogether? We believe that
the answer is ‘yes’, which is why no fewer
than 90 % of the components of the 911
are either new or have been fundamentally
revised. This is our approach to the preser -
vation of tradition. It is precisely how we

respond to the passion for the sports car
and do justice to the 911 legend, and
always with tomorrow in mind.
We have achieved this with a brand new
design and a longer wheelbase, with
refined engines that consume less fuel
but deliver more power, with efficiency-
enhancing technologies such as auto
start /stop, thermal management and
electrical system recuperation, with an
intelligent light weight body that uses a composite blend of aluminium and steel
and a new hood concept on the Cabriolet
models, with a suspension derived from
motorsport, and with a progressive interior
designed for sporty comfort.
All of that is what defines us. In short, it
is the way in which we combine tradition
and innovation, performance and everyday
practicality, form and function. For us,
these are not contradictions, but our
motivation. We are referring to Intelligent
Performance.
Our identit y can be accurately described
by many words, and by one number.

Engineering
Let’s forget the future for a moment.
As we discover it in the present.

Engineering.
What use is the engineering of tomorrow
when it can be found on the road today?
None. So let ’s turn to the here and now.
The engines, as you would expect,
are characterised by six horizontally
opposed cylinders. The 3.4-litre engine in
the 911 Carrera and 911 Carrera Cabriolet
produces 257 kW (350 hp); in the
911 Carrera S and 911 Carrera S Cabriolet,
the 3.8-litre engine develops 294 kW
(400 hp). All models are equipped with
direct fuel injection (DFI) and VarioCam Plus
for increased power and reduced fuel
consumption. This power is transmit ted
to the wheels by the new and efficient
7-speed manual gearbox or, optionally, by efficiency-enhanced Porsche

Doppel kupplung (PDK), which offers
gear changes with no interruption
in the flow of power.
Both engines deliver improved sport y
performance compared with the engine
in the previous model and yet fuel
consumption has been reduced by up
to 16 %. How was this achieved? One
explanation is the reduced capacit y of
3.4 litres in the 911 Carrera models.
Another is the total redevelopment of the
engine peripherals with groundbreaking
efficiency-improving technologies. As standard, these include the auto
start/stop function, electrical system
recuperation and intelligent thermal

management as well as the new, energy-
saving electromechanical steering system
and, in the case of PDK, the introduction
of the coasting function (for more
information, please refer to page 43
onwards).
The chassis is also packed with forward-
looking technology. Fitted as standard
in the 911 Carrera S and 911 Carrera S
Cabriolet, Porsche Torque Vectoring
(PTV) increases dynamic performance.
Available as an option for the S models,
Porsche Dynamic Chassis Control (PDCC)
improves dynamic performance further still. Dynamic engine mounts, included as
part of the optional Sport Chrono Package,
are now available in a 911 Carrera for
the first time. These provide perceptibly
more stable handling under load change
conditions and in fast corners.
The new 911 has a light weight composite
construction in aluminium and steel. Used
extensively and in just the right places,
lightweight aluminium improves fuel
economy and dynamic performance and
helps to achieve a low weight to power
ratio of 4.7 kg / kW (3.5 kg / hp) for the
9 11 C a r r e r a S .
The future of the sports car begins now.

| The new 911 Carrera S
Its identity emerged on the racetrack.
Its home is on the road.

The new 911 Carrera S.
Nothing defines us more than our heritage.
It says a lot about who we are. This is
particularly true of the new 911 Carrera S,
which has all the characteristics you would
expect of a sports car whose origin is in
motorsport.
An elementary component of its DNA,
therefore, is power in the form of a 3.8-litre
engine with direct fuel injection (DFI) and
VarioCam Plus. It delivers 294 kW (400 hp)
at 7,400 rpm, and the maximum torque
of 440 Nm is achieved at 5,600 rpm. In
conjunction with the manual gearbox, the
sprint from 0 to 100 km/h (0 to 62 mph) is
completed in just 4.5 seconds. Top speed
isn’t reached until 304 km/ h (188 mph).
On figures alone, the new 911 Carrera S
excels, particularly in terms of efficiency.
Fuel consumption and CO2 em issio ns
have been reduced by 15 % compared

with the previous model. This has been
possible thanks to the auto start /stop
function, which is available as standard,
and the coasting function in conjunction
with the optional Porsche Doppelkupplung
(PDK).
It ’s not difficult to tell where the
911 Carrera S comes from. You can hear
it in the resonant engine sound and you
can see it in the t win tailpipes in brushed
stainless steel and 20 - inch Carrera S
wheels. You can also feel it, thanks to Porsche
Active Suspension Management (PASM),
which is fit ted as standard, or the optional
PASM sports suspension with sport y

aerodynamics and the ride height lowered
by 20 mm. Or the optional Sport Chrono
Package and dynamic engine mounts.
Available as standard, Porsche Torque
Vectoring (PTV), or Porsche Torque
Vectoring Plus (PTV Plus) in conjunction
with the optional PDK, increase traction.
Porsche Dynamic Chassis Control (PDCC),
the active roll stabilisation system, is
available as an option and improves agility,
comfort and safet y. On the subject of safet y, the brakes at
the front of the new 911 Carrera S come
equipped for the first time with monobloc
fixed calipers with six instead of four

pistons for improved braking performance
and a shorter braking distance. Bi-Xenon
headlights are standard and the Porsche
Dynamic Light System (PDLS) is available
as an option.
There is no doubt. The new 911 Carrera S
knows its roots, and embraces them with
efficiency, power and sporty performance.

A widely held belief about motorsport is
that power is the only thing that mat ters.
From experience, we know bet ter. Extra
horsepower alone has never been enough
to win a single race. Much more important
to us are ideas – ideas that inspire more
intelligent vehicle concepts and more ef fi-
cient drive systems. The same applies on
the road. It ’s about get ting the most out
of what you’ve got. select neutral and release the clutch
pedal. In cars with Porsche Doppel
kupplung
(PDK), the engine switches off whenever
you stop and leave your foot on the
brake pedal.
All audio and communication systems
remain switched on and the climate con -
trol continues to maintain your selected
temperature. The only differences you
will notice are the silence at the rear and
the fuel saving. As soon as you operate
the clutch or release the brake, the
engine will restart swiftly and smoothly.
The auto start/stop function may remain
inactive under particular circumstances,
extreme outside temperatures, when the
SPORT but ton is selected or if bat tery
charge is low. It is also possible to deacti -
vate the function manually using a
separate but ton on the centre console.
Thermal management.
The new thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow.
In this way, the engine and gearbox reach
their optimum operating temperature
sooner. As a result, fuel consumption is
reduced through increased combustion
efficiency and lubrication performance.

Electrical system recuperation.
The new 911 models are also equipped
as standard with fuel-saving electrical
system recuperation technology.
The vehicle bat tery is recharged by the
alternator, predominantly under braking.
Under acceleration, on the other hand,
the power draw of the alternator is limit -
ed to increase the engine output availa -
ble for driving. The electrical systems
are supplied by the electrical energy
stored during the recharging process.
Temperament | Engines
Auto start/stop function.
The auto start/stop function is standard
in the new 911 models.
In cars with the manual gearbox, the
engine switches off automatically when,
for example, you stop at traffic lights,
Not as thirsty as you might think.

Electromechanical power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the new electromechanical power steering.
Statistics show that a car drives in a
straight line 90
% of the time. Unlike
conventional hydraulic pumps, the electric
motor uses energy only when the steering
wheel is actually turned. The absence
of hydraulic fluid also makes the system
more beneficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the comfort-enhancing
power-steering system, is available
as an option for the 911 Carrera models.
At high speeds, the steering is as firm as
you would expect and responds with
extreme precision while steering comfort
remains as high. At low speeds, the steering
ratio of Power steering Plus adjusts for
much easier manoeuvring and parking.
SPORT button.
Fit ted as standard, the new SPORT
but ton enables you to select a suspension
setup where the emphasis is on either
comfort or sport y performance. At the
push of a button, the electronic engine
management system switches the engine
mapping to offer an even sharper
response and engine dynamics that are
more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen sooner. In addition, coasting mode and
the auto start/stop function are automati
-
cally deactivated. If fitted, the optional
sports exhaust system is also activated
automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available
as an option. This integrated system
provides simultaneous enhancement for
the chassis, engine and transmission.
Every day can be sports day.

| Chassis and body
Included in the package are a performance
display, a digital and an analogue stop -
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management (PASM) and, in the S model, optional

Porsche Dynamic Chassis Control (PDCC)
switch to a harder damping set ting
and offer more direct steering and,
therefore, better road holding.
In SPORT PLUS mode, the trigger thresh -
old
for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit acceleration. For maximum 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 gearshif t 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 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 new 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. Based on the
engine mounts of the 911 GT3 and
911 Turbo models, it is the first time that they have been available for a

911 Carrera. Even if track racing is not
for you, dynamic engine mounts make
a decisive contribution to dynamic
performance on the road, too.
The electronically controlled system mini -
mises the oscillations and vibrations of the
entire drive train, 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
provide a higher level of comfort.

Exhaust 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 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, newly developed
cataly tic converters provide ef ficient
emission control.
The stereo Lambda control circuitr y
controls and monitors each cylinder bank
separately. For each exhaust tract,
oxygen 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
ecological reasons. This forms the basis
for achieving low fuel consumption
values in conjunction with outstanding
performance.
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 new 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 new
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.
