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 sportscar and for the environment.
Then there is our reputation as an iconic
sportscar 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 sportscar, 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 pres -
ervation of tradition. It is precisely how we
respond to the passion for the sportscar
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,
with a suspension derived from motor
-
sport, and with a progressive interior
designed for sport y 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.

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 produces 257 kW
(350 hp); in the 911 Carrera S, the 3.8-
litre engine develops 294 kW (400 hp).
Both 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 Porsche Doppelkupplung (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. 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 infor
-
mation, please refer to page 39 onwards).
The chassis is also packed with forward-
looking technology. Fit ted as standard
in the 911 Carrera S, Porsche Torque
Vectoring (PT V) increases dynamic perfor -
mance. Available as an option for the
S model, 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 for
the 911 Carrera models 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 sportscar begins now.

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
limited to increase the engine output
available 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.

Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your pocket.
As soon as you touch the door handle or
the Porsche Crest on the luggage com
-
partment 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.
To lock the vehicle, you simply press the
but ton on the outside of the door handle.
Porsche Entry & Drive then locks the
vehicle and activates the engine immobi -
liser and steering column lock.
Anti-theft protection.
All 911 Carrera models are equipped as
standard with an immobiliser with in-key
transponder and an alarm system with
radar-based interior surveillance. The
system secures the doors, luggage com -
partment, passenger compartment and
ignition lock.
Porsche Vehicle Tracking System
(PV TS).
The Porsche Vehicle Tracking System
(PV TS) is fit ted as standard on all 911
models. The system
makes it possible to
locate a stolen vehicle across most of
the countries of Europe. The preparation
package includes a special wiring loom
and a
tilt sensor for the alarm system.
Audio and communication in the new 911
Sound Package Plus.
The Sound Package Plus is fit ted as
standard. The system comprises a
separate amplifier with a total output
of 235 wat ts, seven amplifier channels
and nine loudspeakers, all of which
combine to create the perfect interior
sound experience.
Identity is to do with where you come from.
Sometimes, it’s also to do with where you want to be.

Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sportscars 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-efficient technolo -
gies such as auto start/stop, thermal
management, electrical system recupera -
tion, direct fuel injection, coasting mode
and VarioCam Plus.
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.
1)

Fuel economy and recycling.
Intelligent light weight construction has
been fundamental to the Porsche identit y
since 1948, for both economic and
ecological reasons. This forms the basis
for achieving low fuel consumption
values in conjunction with outstanding
performance.
It is economical thanks to the high
proportion of aluminium, magnesium,
plastics and super- high -strength sheet
steel used. This is substantially more
stable and lighter than conventional steel.
It is also ecological because all materials
used are meticulously selected. We use
only innovative and environmentally friendly
components. All light weight materials are
easily recyclable and each material is labelled to facilitate its separation 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 up to around
95 % recyclable.
In addition, Porsche for the most part
uses 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 already 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.
