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.
For fuel consumption, CO2 emissions and efficiency class, please refer to pages 141/143.

Climate control.
The 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.
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
speed range and is activated using a but -
ton on the steering column control stalk.

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- off timer
keeps the day time running lights, the
taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Adaptive cruise control with Porsche
Active Safe (PAS).
Available as an option, this cruise control
function regulates your speed according
to the distance bet ween your vehicle and
the vehicle in front. A radar sensor moni -
tors the road ahead up to a distance of
200 m. If you have set a cruising speed
but have begun to gain on the vehicle in front because it is driving more slowly,
this is detected by the radar sensor.
The system now reduces the speed

of your vehicle at a maximum rate of
3.5 m/sec
2 by restricting the throt tle
or by applying the brakes appropriate
to the prevailing situation until the dis -
tance that you have preset is maintained.
Your vehicle will now continue at a reduced speed. If the other vehicle

decelerates further, adaptive cruise
control will continue to reduce your
cruising speed – even down to a halt. For additional safet y, if the system detects
that the distance from the vehicle in front
is decreasing, it will also prepare your
vehicle for braking by precharging the
braking system so that the brake pads are already in light contact with the
brake discs. However, drivers still have
to perform heavier braking themselves.
As soon as the road ahead clears again,
your vehicle will accelerate back up to
the cruising speed originally set.
If your vehicle approaches the vehicle
in front too quickly, Porsche Active Safe
(PAS) will issue audible and visual warn
-
ings. In addition, the system briefly jerks
the brakes and if necessary initiates
target braking, with any braking pressure
applied by the driver being increased
within certain system limits.

An opera in a world of soap operas.

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 821 wat ts,
12 loudspeakers including an active
subwoofer with 300 -wat t class D amplifier, a total diaphragm surface area
of more than 1,340 cm
2, and a frequency
response of 35 Hz to 20 kHz.
In the 911 models, the Burmester
® system
uses 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 after extensive in-car audio testing.

The t weeters are ribbon-based air
motion transformers (AMT) and ensure
unmistakably fine, clear and undistorted
high-frequency sound reproduction with
excellent level stability. All loudspeaker
housings are perfectly matched and
deliver superior bass foundation, defi -
nition 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.
