| Exterior design
The vehicle architecture, with a wider
track at the front axle and the lower roof
line, gives the front of the 911 a dynamic
appearance that is sport y and elegant.
It has also helped us to achieve a low drag
coefficient of 0.29 for the 911 Carrera. Fit ted as standard, the Bi
­Xenon head ­
lights still have the familiar oval ­shaped
surrounds for classic appeal and reveal
their technically impressive inner work ­
ings. The Porsche Dynamic Light System
(PDLS) with dynamic cornering lights
and speed ­sensitive headlight control
logic is available as an option. The direction indicators, daytime running
lights and position lights are all LEDs and
are integrated into the separate front light
units. Their slimline design contrasts with

that of the rounded headlights. Together
with the two integral air intakes, they
make the front of the 911 unmistakable. At the rear, every thing is clean and
sharp: the styling, the appearance and
the effect. This is due not least to the
distinct lines and narrow LED taillights
which accentuate the horizontal contour
­
ing of the rear. The illuminated rear
light strip on the all ­wheel ­drive models
further enhances the effect. One unmistakable Porsche feature is

the stainless steel tailpipes. On the
911 Carrera S models, t win tailpipes
are fit ted on both sides. The wide rear
spoiler is extendable which reduces lift
in all driving situations and increases
driving stability. The 911 Carrera models and the

911 Carrera S models are equipped
as standard with 19 ­inch and 20 ­inch
wheels, respectively. Their large dimen ­
sions enhance the sport y presence of
the 911. The t yres have a large rolling
circumference for improved comfort
and performance. Even the logo on the rear has an impor
­
tant function to perform. It is, after all,
the hallmark of the Porsche identity.
In summary, form always follows function.
As a design principle, it couldn’t be more
simple, but it ’s what makes the 9 11 a 9 11.

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
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
9 11 Carrera S models operate a t wo ­
stage
system.
The entire intake system is made from
light weight plastic. In the 9 11 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 powerful at higher rpm.
Exhaust system.
The exhaust system of the 911 Carrera
models has been 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
compati bility 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.

| Chassis and body
PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension
is lowered by 10 mm.
PASM has t wo modes, which can be
selected using a separate but ton on
the centre console: ‘Normal’, which is a
blend of performance and comfort, and
‘Sport ’ where the setup is much firmer. Sensors record the body movements

that accompany powerful acceleration,
braking or uneven road surfaces. In the
911, the number of sensors has been
increased for improved data acquisition
and even more ef ficient control interven­
tions. The PASM control unit evaluates
the driving conditions and modifies the
damping force on each of the wheels in
accordance with the selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer
rating, thereby improving contact between
the wheels and the road. When the road
surface improves, PASM automatically
reverts to the original, harder rating. If
‘Normal’ mode is selected and the driver’s
st yle becomes more assertive, PASM
automatically switches to a harder rating.
Damping firms up, and driving stability
and road safet y are increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The PASM sports suspension is available
as an option for the 911 Carrera Coupé
models in conjunction with 20 ­inch wheels
and Porsche Torque Vectoring (PTV) or
Porsche Torque Vectoring Plus (PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti ­roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler extends even further. These not only

further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even
better performance.

Control, discipline, precision.

At Porsche, we take driving pleasure very seriously.

Brakes.
Another crucial piece of the Porsche
identit y is the brakes. We value them as
highly as we do our engines and chassis.
They set standards for deceleration and
stabilit y, and give the driver the reassur ­
ance needed to push the car to the limits
of its performance.
The 911 Carrera base models are fit ted
front and rear with anodised black four ­
piston aluminium monobloc fixed calipers.
All brake discs have a diameter of 330 mm.
On the S models, we have fit ted larger
brakes and more brake pistons to cope
with the higher engine power of these
models. Consequently, they feature red
six­piston monobloc aluminium fixed
brake calipers at the front and four ­piston
aluminium monobloc fixed calipers at
the rear. The brake disc diameter is
340 mm at the front and 330 mm at the
rear. The results are enhanced braking
performance and stability.
On all models, the brake calipers have
an enclosed monobloc construction.
This makes them tougher but lighter and enables a more rapid response and
release of the brake even under extreme
loads. The pedal travel is short and

the biting point precise. The brake discs
are cross ­drilled for better performance
in the wet.
Other benefits of the standard braking
system include the anti ­lock braking
system (ABS), designed to keep deceler ­
ation constant. Pedal effort is reduced
and braking response improved by an
8 ­/9 ­inch tandem vacuum brake booster.
In the S models, brake disc cooling is
further enhanced by modified air spoilers.
