| Exterior design
The new vehicle architecture, with a wider
track at the front axle and the lower
roof line, gives the front of the new 911
a dynamic appearance that is sport y
and elegant. Fit ted as standard, the new
Bi-Xenon headlights still have the familiar
oval-shaped surrounds for classic appeal
and reveal their technically impressive
inner workings. 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 new 911 unmistakable.
At the rear, every thing feels sharper: the
styling, the appearance and the effect.
This is due not least to the distinctive
profile edge and new LED taillights, their
stretched design accentuating the horizontal contouring of the rear.

The characteristic reflector units have
been positioned lower down but are
still recognisable, particularly at night.
The stainless-steel tailpipes have been
rest yled. On the 911 Carrera S models,
t win tailpipes are fit ted on both sides.
One new feature is the wider, extendable rear spoiler, which reduces lift in all

driving situations and increases driving
stability.The 911 Carrera and the 911 Carrera S
are equipped as standard with 19-inch
and 20 -inch wheels
respectively. One
inch larger than
those on the respective
previous model, they enhance the sport y
presence of the new 911. Newly
developed t yres with increased
rolling circumference improve both
comfort and performance.
In summary, form always follows
function. As a design principle, it
couldn’t be more simple, but it ’s
what makes the 911 a 911. It ’s also how we have managed to
achieve a very low drag coefficient of
just 0.29 on the Coupe models and
0.30 on the Cabriolets.
Even the logo on the rear has an important
function to perform. It is, after all, the
hallmark of the Porsche identity.

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.

| 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 new 911, the number of sensors
has been increased for improved data
acquisition and more ef ficient control
interventions. The PASM control unit eval -
uates 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
bet ween 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 stabilit y 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 new PASM sports suspension is
available as an option for the 911 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.

S a f e t y.
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 and 911 Carrera Cabriolet
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 911 Carrera S models, we have
fit ted larger brakes and more brake pistons
to cope with the increased engine power
of these models. The new generation of
brakes features red six-piston 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 a
reduction in stopping distance compared
with that of the previous model.
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 decelera -
tion constant. Pedal effort is reduced and
braking response improved by a newly
developed 8-/9-inch tandem vacuum
brake booster. In the S models, brake disc
cooling is further enhanced by modified
air spoilers.
