911 Carrera models: 390 Nm at 5,600 rpm, 257 kW (350 hp) at 7,400 rpm
The new 3.4-litre engine.
The 911 Carrera and the 911 Carrera
Cabriolet are equipped with a 3.4-litre
boxer engine with direct fuel injection
(DFI) and VarioCam Plus. It develops

257 kW (350 hp) at 7,400 rpm and the
maximum torque is 390 Nm at
5,600 rpm.
For the 911 Carrera with 7-speed manual
gearbox, this means acceleration from
0 to 100 km/ h (0 to 62 mph) in 4.8 sec -
onds and a top speed of 289 km/ h
(179 mph). The figures
achieved by the
911 Carrera Cabriolet
are 5.0 seconds
and 286 km/ h (177 mph). With the
optional Porsche Doppelkupplung (PDK),

it means figures of 0 to 100 km/ h
(0 to 62 mph) in just 4.6 seconds and
a top speed of 287 km/ h (178 mph)
for the 911 Carrera and 4.8 seconds
and 284 km/ h (176 mph) for the
911 Carrera Cabriolet.
The new 3.8-litre engine.
The 911 Carrera S and the 911 Carrera S
Cabriolet are powered by a 3.8-litre boxer
engine with direct fuel injection (DFI)
and VarioCam Plus. It produces 294 kW
(400 hp) at 7,400 rpm and the maximum
torque of 440 Nm is achieved at
5,600 rpm.
As a result, the new 911 Carrera S
with 7-speed manual gearbox completes
the sprint from 0 to 100 km/ h (0 to
62 mph) in
4.5 seconds and reaches
a top speed of 304 km/ h (188 mph). The
911 Carrera S Cabriolet
achieves 4.7 sec -
onds and 301 km/ h (187 mph). With
the
optional Porsche Doppelkupplung (PDK),
the figures are 0 to 100 km/ h (0 to
62 mph) in 4.3 seconds and a top speed
of
302 km/ h (187 mph) for the Coupé and
4.5 seconds
and 299 km/ h (185 mph) for
the Cabriolet.

Engines
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.

Climate control.
The new 911 models feature t wo -zone
automatic climate control as standard
with an enhanced ventilation effect and
separate temperature controls for the
driver and front passenger. The available
air conditioning modes are gentle,

normal and strong.
An active carbon filter traps particles,
pollen and odours and an automatic
air-recirculation function permanently
monitors air quality, reduces humidity
and switches from fresh to recirculated
air when required. A demister function keeps the windows
clear in cold weather. In warmer weather,
a solar sensor helps the climate control

to detect strong sunlight and automatically
compensate for the comfort of both the
driver and front passenger.
HomeLink®
(programmable garage door opener).
As an option, it is possible to have
a programmable garage door opener
integrated into the overhead console.
At the push of a but ton, it controls up
to three different garage doors, lighting
systems or alarm systems.
Many things have practical qualities.
Even more have a sporty function.
And some are just extremely convenient.

Additional comfort and convenience features.
Light design package (overhead console)
Light design package (door pulls) Light design package (rear)
Light design package.
The optional light design package is both
practical and aesthetically appealing.
It comprises dimmable LEDs in the over -
head console and in the areas of the
door pulls, door storage compartments,
front foot wells and rear seats.
‘Welcome Home’ lighting.
For convenience, particularly at night,
the ‘Welcome Home’ lighting function
automatically switches on the LED day -
time running lights for a defined period
whenever the vehicle is opened or
closed using the key remote. A customisable delayed switch - of f timer
keeps the daytime running lights, the

taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Cruise control.
This automatic speed control function
is available as an option. For greater
driver comfort on long stretches of road,
cruise control operates in the 30 –240 km/ h
(18 –149 m p h )
speed range and is activat -
ed using a
button on the steering column
control stalk.

Words can barely describe the 911 experience.

Sound can.

Burmester
® High-End Surround Sound System.
When t wo iconic German manufacturers
join forces, the result is special. We’re
referring to Porsche and Berlin-based
Burmester
®, one of the most respected
manufacturers of high-end audio equip -
ment worldwide, and the Burmester
®
High-End Surround Sound System.
The technologies behind the system are
based on the finest premium home audio
systems Burmester
® has to offer.
The system owes its eminence to count -
less details, and one goal: perfection
in sound.
The system has 12 amplifier channels
with a total output of more than 821
watts, 12 loudspeakers including an
active subwoofer with 300 -wat t class D amplifier, a total diaphragm surface area
of more than 1,340 cm², and a frequency
response of 35 Hz to 20 kHz.
For the first time in a 911, Burmester
®

has introduced the patented integral
subwoofer, which replaces the familiar
separate subwoofer and loudspeaker
arrangement of other systems. This saves
weight and has a beneficial impact on
acoustic performance.
Crossover technology has been carried
over more or less unmodified from the
home audio sector. Analogue and digital
filters have been optimally defined for
their new installation location and finely
tuned af ter extensive in - car audio testing. The t weeters are ribbon-based air motion
transformers (AMT) that have been
designed specifically for the 911. For
unmistakably fine, clear and undistorted
high-frequency sound reproduction with
excellent level stability. All loudspeaker
housings are perfectly matched and deliver
superior bass foundation, definition and
impulse accuracy. As yet unequalled

in the 911, the result is a natural and
richly textured spatial sound even at

top volume.
The pure, sport y design with galvanised
surrounds and Burmester
® logos on
selected loudspeakers make it clear that
the appeal of the Burmester
® High - End
Surround Sound System is as much about the visual as it is the audio.

Typically Porsche.
Cue the encore.
