| 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.

| The new 911 Carrera Cabriolet
The future of the sports car
is wide open again.
The new 911 Carrera Cabriolet.
Sometimes, the best option is to free
your mind, to look at things from a fresh
perspective and to explore your own
direction, not least when you’ve set
yourself ambitious goals for the future.
These goals can be achieved by opening
yourself up to new ideas.
This is the direction explored by the
new 911 Carrera Cabriolet. With forward-
looking hood engineering, lightweight
materials and an integrated wind deflector,
it conceives a new kind of freedom and
broadens the appeal of the sports car.
Smooth and firm, light and robust, the
design of the new hood is impressive in
terms of both appearance and
construction. It is made from three
ultra-lightweight magnesium elements
and is covered in fabric. This saves
weight, improves
aesthetics, and also
reduces unwanted noise. What you can
still hear, however, is the unadulterated
sound of your 911.
The new wind deflector is fit ted as
standard and offers practically

draught-free driving and minimal wind
noise. Operation could not be easier.
Integrated directly behind the rear seats,
it folds out electrically in just t wo seconds
and remains operable no mat ter how
fast you drive your 911. The performance figures of the new

911 Carrera Cabriolet reflect the ambi -
tious goals achieved by our engineers.
The new, downsized and rear-mounted
3.4-litre flat-six engine delivers 257 kW
(350 hp) at 7,400 rpm and enables
a top speed of 286 km/ h (177 mph).
Compared with the previous model, fuel
consumption and CO
2 emissions have
been reduced by 15 %.
In summary, this articulate concept forms
the basis for a self-assured personalit y.
Typified by its courage to adapt and
change, it derives pleasure from exploring
new directions. After all, the future is
wide open.

| The new 911 Carrera S Cabriolet
Porsche 356, Porsche 550, Porsche Carrera GT:
openness has always been a Porsche tradition.
The new 911 Carrera S Cabriolet.
Open-top driving is integral to Porsche
history. It began back in 1948 with the
No. 1. The convertible variant of the
first 356 became a legend, as did its
descendent, the Porsche 550 Spyder.
In 1982, the first 911 Carrera model
in cabriolet form was introduced to the
road. Two things that all open-top
Porsche cars have in common are an
urge for sport y acceleration and unlimited
driving pleasure. The time has come to
carry this tradition on into the future.
The new 911 Carrera S Cabriolet does
just that.
That explains what motivates us, and this
describes what drives the car: the new 3.8-litre engine with direct fuel injection
(DFI) and VarioCam Plus, which produces
294 kW (400 hp) at 7,400 rpm. The

new 911 Carrera S Cabriolet completes
the sprint from 0 to 100 km/ h (0 to
62 mph) in just
4.7 seconds and reaches
a top speed of 301 km/ h (187 mph).
These are impressive performance
capabilities, founded on the principle
that, if you want to keep moving, you
shouldn’t carry unnecessary weight. This
is precisely why the new 911 Carrera S
Cabriolet incorporates extensive use
of lightweight materials.
The hood has a crucial role in this respect.
On the new 911, the hood has been fun -
damentally revised. Integrated magnesium
elements make the hood light yet
extremely robust. The hood opens and
closes in only 13 seconds and is operable
up to a speed of 50 km/ h (31 mph).
With the hood closed, the car’s profile is
optimised for
aerodynamic performance,
which explains
the low drag coefficient
of 0.30. Wind noise is practically elimi -
nated.
The new, integrated wind deflector
manipulates headwind to create ideal
conditions. Electrically powered and
installed directly behind the passenger
cell, it provides effective protection
against air turbulence.
Twin tailpipes in stainless steel also
make a clear statement. The 20 -inch
Carrera S wheels afford an unobstructed
glimpse of the brake calipers with a
red painted finish. As you would expect,
the 911 Cabriolet offers a high level of
occupant safet y and features an effective
roll-over protection concept as well as
full-size airbags for the driver and front
p a s s e n g e r.
Without question, the new 911 Carrera S
Cabriolet has remained faithful to the
sporty spirit of its predecessors and is
ensuring that the legacy lives on in the
21s t ce n t u r y.

Engines
To give more and take less.
That’s Porsche engineering.

Engines.
You could ask whether the sports car is
still relevant. It would be a good question,
but you might as well ask the same of
dreams.
The answer to both questions lies in
the future or, to be more precise, in the
future of the sports car. In the new 911,
the future has already begun. The highly
ef ficient, state - of-the -art engines make
a considerable contribution to reducing
fuel consumption, but their sound is still
unmistakably Porsche. The new 911 engines are also unmistaka
-
bly sport y thanks to the new SPORT
but ton fit ted as standard. At the push
of a button, the engine becomes tuned
for a sharper response and engine
dynamics that are even more direct.
The 3.4-litre engine of the new
911 Carrera models demonstrates, there -
fore, that performance and efficiency
need not be mutually exclusive. Rather,
the downsized engine capacit y and
increased maximum torque are the intelli -
gent basis by which power output
can be increased in an environmentally
acceptable and sustainable way. Fuel consumption and CO
2 emissions have
been reduced by up to 16 % compared
with the previous model.
In their search for improved efficiency,
our engineers analysed an extensive series
of engine components. Answers were
found, including rapid heating of the
engine and gearbox to normal operating
temperature after an engine start by
the new thermal management system,

improved air induction and the extremely
effective direct fuel injection (DFI).
The same principle applies to the 3.8-litre
engine in the 911 Carrera S models. There has been no change in displacement
since the previous model, but power

output has been increased while fuel
consumption has been reduced by up
to 15 % .
Weight is critical to efficiency. This is
why the engines have a light-alloy
construction, which makes them light -
weight and structurally rigid for improved
fuel economy and a long life.
The engine is the intelligent core of our
identit y. What else could the ‘Dr. Ing.’ in
our company name possibly stand for?

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.

DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the new multi-
hole injectors have been optimised for
torque, power output, fuel consumption,
emissions and ef ficient combustion.
With direct injection, the engine manage-
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and fuel economy. operation to the prevailing conditions.
This results in instant acceleration,
extremely smooth running and an
extraordinary level of tractive power,

but with a comparatively low level of
fuel consumption.
For faster heating of the catalytic converters
after a cold start and optimum torque in
the upper load range, up to three injection
pulses take place per combustion cycle.
DFI improves the internal cooling of

the combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression
ratio, which helps to deliver more output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the
Lambda sensors.

Integrated dry-sump lubrication.
Integrated dr y-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 con -
trolled oil pump supplies the lubricating
points inside the engine as and when
required. This results in optimum supply
of oil, low fuel consumption and, there -
fore, lower exhaust emissions.
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 new 911 Carrera
model range, the resonator volume of the
air filter housing varies with engine speed
to bring added character to the engine
sound, which becomes much more power -
ful at higher rpm.
Exhaust system.
The exhaust system of the new 911
models has been completely redesigned,
acoustics included.
The stainless-steel exhaust system com -
prises t wo distinctive and independent
exhaust tracts. The cataly tic converters
heat up rapidly for effective emissions
reduction.
A selectable t win -tube 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 Stabilit y 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 conditions, 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.

Transmission
The long and winding road is where you’d like to be.
Sometimes, it pays to take the direct route.

Transmission.
The new 7-speed manual gearbox.
Pure, direct, precise. Short shif t move -
ments and an optimum transition from
one gear to the next. That ’s exactly what
you would expect of a Porsche manual
gearbox.
What you might not have expected is a
7-speed manual gearbox that combines
a high level of sport y performance with
an equally high level of efficiency and
offers extra comfort for longer journeys. It’s an exceptional innovation, and not
only in the sports car segment.
The design of this manual gearbox is
based in principle on that of Porsche
Doppelkupplung (PDK). Gears 1 to 6 have
a sports ratio and top speed is reached
in 6th gear. The additional 7th gear,

however, has a long ratio, which reduces
torque and helps to reduce fuel consump -
tion. Lower engine revs at fast driving
speeds also ensure a high level of com
fort
on long stretches of road. In addition
, a gear indicator in the rev counter reminds
you which gear has been selected. The
upshift indicator in the instrument cluster
helps you actively conserve fuel.
Thanks to the elevated centre console,
the gear lever is within easy reach –

ideal for sport y gear changes.
Whether you select a sporty or comfortable
gear, the way you reach your destination
is in your own hands.
