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 models produces 257 k W
(350 hp); in the 911 Carrera S models,
the 3.8-litre engine develops
294 kW
(400 hp). All variants are equipped
with direct fuel injection (DFI) and
VarioCam Plus for high power and
comparatively low fuel consumption. Power is transmit ted to the wheels by the
7-speed manual gearbox with the highest
gear designed specifically with fuel econ
-
omy in mind or, optionally, by efficiency-
enhanced Porsche Doppel kupplung (PDK),
which offers gear changes with no inter -
ruption in the flow of power.
On the 911 Carrera all-wheel- drive
models, Porsche Traction Management
(PTM) distributes the power to the
wheels according to weather and road
conditions. Handling remains poised,
particularly when the car is being driven
to its limits. As a result, you are safer not just in the wet and snow, but also
when adopting a sport y driving st yle.

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
(PT V) – or Porsche Torque Vectoring Plus
(PTV Plus) in conjunction with PDK –
increases dynamic perfor mance. Available
as an option for the S models, Porsche
Dynamic Chassis Control (PDCC)
improves dynamic performance further
still.
Dynamic engine mounts, available as an
option for all models, provide tangible,
more precise handling – not only in the
bends.
The 911 has a lightweight 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 an excellent weight-
to -power ratio of 4.8 kg / kW (3.5 kg / hp)
for the 911 Carrera S, for example.
The future of the sports car starts now.

How about some leisure in between?

The 911 Carrera.
In the 21st century, we find ourselves
caught bet ween all kinds of opposites on
a daily basis: bet ween the demands of
our work life and our private life, between
the real world and virtual realit y. How can
they all be reconciled? With a strong iden -
tit y and a sports car that has incorporated
many contradictory notions since 1963.
Sportiness and everyday practicality are
a prime example. The new 911 Carrera is
equipped as standard with direct fuel
injection
(DFI) and VarioCam Plus for high
power, high torque, efficient combustion
and, as a result, comparatively low fuel
consumption. Tradition and innovation blend seamlessly
together in the 3.4-litre, six-cylinder
horizontally opposed engine. The figures
speak for themselves. The maximum
power of 257 kW (350 hp) is available at
7,400 rpm and the maximum torque of
390 Nm is generated at 5,600 rpm. Even
more impressively, the car accelerates
from 0 to 100 km/ h in 4.8 seconds and
reaches a top speed of 289 km/ h.
The 911 Carrera generates powerful
forces, which are transmit ted precisely
and directly to the wheels by the 7-speed
manual gearbox. As with the optional PDK,
gears 1 to 6 have a sports ratio, while 7th gear has a long ratio for reduced fuel
consumption. The SPORT but ton, which
is fit ted as standard, makes it possible to
select an even more responsive engine
and transmission setup.
In terms of form and function, the single
tailpipes are especially imposing and
emit a sound that is t ypically Porsche.
The 19-inch Carrera wheels are fit ted as
standard and offer excellent driving
stability and performance.
Sports car technology as standard, in
the form of black four-piston aluminium
monobloc fixed calipers, Porsche
Stabilit y Management (PSM) and Bi-Xenon
headlights, shows that sportiness and
safet y are not mutually exclusive.
Sport, moderation, everyday practicality
and st yle. Four key themes, one unifying
concept: the 911 Carrera.

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

The 911 Carrera S.
Nothing defines us more than our heritage.
It says a lot about who we are. This is
particularly true of the 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 maxi-
mum torque of 440 Nm is achieved
at 5,600 rpm. In conjunction with
the manual gearbox, the sprint from
0 to 100 km/ h is completed in a
mere 4.5 seconds. Top speed isn’t
reached until 304 km/ h.
On figures alone, the new 911 Carrera S
excels, particularly in terms of efficiency,
fuel consumption and CO
2 emissions.
This is made possible by the auto start /
stop function, which is available as
standard, and the coasting function

in conjunction with 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 even
sportier 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 and driving stability.
Porsche Dynamic Chassis Control (PDCC),
the active roll stabilisation system, is
available as an option and improves
agility, comfort and safety.
On the subject of safet y, the brakes at
the front of the 911 Carrera S come
equipped with monobloc fixed calipers with six, instead of four, pistons for
improved braking performance and a
shorter braking distance. Bi-Xenon
headlights are standard, while the
Porsche Dynamic Light System (PDLS)
and LED main headlights including
Porsche Dynamic Light System Plus
(PDLS
+
) are available as options.
There is no doubt. The 911 Carrera S
knows its roots, and embraces them
with efficiency, power and sport y
performance.

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 911,

the future is already here. The highly
efficient, state-of-the-art engines make

a considerable contribution to the
comparatively low fuel consumption,

but their sound is still unmistakably
Porsche.
The 911 engines are also unmistakably
sport y thanks to the SPORT but ton fit ted
as standard. At a single push, the engine
becomes tuned for a sharper response
and engine dynamics that are even more
direct.
The 3.4-litre engine of the 911 Carrera
models demonstrates, therefore,
that performance and efficiency need
not be mutually exclusive. Rather, the
comparatively low engine capacity
combined with a high maximum torque
are the intelligent basis by which high
power output can be achieved in
an environmentally acceptable and
sustainable way.
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
thermal management system, improved
air induction and extremely effective
direct fuel injection (DFI).
Weight is critical to efficiency. This is
why the engines have a light-alloy
construction, making them lightweight
and yet structurally rigid. The result is
comparatively low fuel consumption and
a long service life. The engine is the intelligent core of our
identit y. What else could the ‘Dr. Ing.’ in
our company name possibly stand for?

DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the multi -hole
injectors have been optimised for torque,
power output, fuel consumption, emissions
and efficient 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 improves the combustion process
and fuel economy.
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 cataly tic 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.

VarioCam Plus.
VarioCam Plus is a two- in
-one engine
concept for adjusting the intake
camshafts and switching the lift of the
intake valves.
The system first differentiates bet ween
driver inputs that typify normal,
everyday driving and those inputs
that demand maximum performance.
The electronic engine management
system then seamlessly adapts valve
operation to the prevailing conditions.

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.

The long and winding road is where you’d like to be.
Sometimes, it pays to take the direct route.
Transmission.
The 7-speed manual gearbox.
Pure, direct, precise. Short shift 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 comfort
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 sport y or comfortable
gear, the way you reach your destination
is in your own hands.
