Meetings, conferences, business lunches.
How about some leisure in between?

The new 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, ef ficient combustion
and, as a result, comparatively low fuel
consumption. Tradition and innovation blend seamlessly
together in the new rear-mounted 3.4-litre
flat-six engine thanks to its downsized
capacity. Despite the reduced displace
-
ment, the engine is capable of delivering
even more power to the road than its
3.6-litre predecessor.
The figures speak for themselves.
The maximum power of 257 kW (350 hp)
is available at 7,400 rpm and the maxi -
mum torque of 390 Nm is generated
at 5,600 rpm. Yet, in conjunction with
Porsche Doppelkupplung (PDK), fuel
consumption and CO2 emissions have been
reduced by 16 % compared with the
previous model. Even more impres
sively,
the car accelerates from 0 to 100 km/ h
(0 to 62 mph) in 4.8 seconds and reach -
es a top speed of 289 km/ h (179 mph).
The new 911 Carrera generates powerful
forces, which are transmit ted precisely
and directly to the wheels by the new
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 respon -
sive engine and transmission setup.
In terms of form and function, the new
single tailpipes are especially imposing and emit a sound which is t ypically
Porsche. The 19-inch Carrera wheels are
fit ted as standard and improve driving
stability and performance.
Sports car technology as standard, in

the form of black four-piston monobloc
aluminium fixed calipers, Porsche Stability
Management (PSM) and Bi-Xenon head -
lights, shows that sportiness and safety
are not mutually exclusive.
Sport, moderation, everyday practicality
and st yle. Four key themes, one unifying
concept: the 911 Carrera.

| The new 911 Carrera S Cabriolet
Porsche 356, Porsche 550, Porsche Carrera GT:
openness has always been a Porsche tradition.
The new 911 Carrera S Cabriolet.
Open-top driving is integral to Porsche
history. It began back in 1948 with the
No. 1. The convertible variant of the
first 356 became a legend, as did its
descendent, the Porsche 550 Spyder.
In 1982, the first 911 Carrera model
in cabriolet form was introduced to the
road. Two things that all open-top
Porsche cars have in common are an
urge for sport y acceleration and unlimited
driving pleasure. The time has come to
carry this tradition on into the future.
The new 911 Carrera S Cabriolet does
just that.
That explains what motivates us, and this
describes what drives the car: the new 3.8-litre engine with direct fuel injection
(DFI) and VarioCam Plus, which produces
294 kW (400 hp) at 7,400 rpm. The

new 911 Carrera S Cabriolet completes
the sprint from 0 to 100 km/ h (0 to
62 mph) in just
4.7 seconds and reaches
a top speed of 301 km/ h (187 mph).
These are impressive performance
capabilities, founded on the principle
that, if you want to keep moving, you
shouldn’t carry unnecessary weight. This
is precisely why the new 911 Carrera S
Cabriolet incorporates extensive use
of lightweight materials.
The hood has a crucial role in this respect.
On the new 911, the hood has been fun -
damentally revised. Integrated magnesium
elements make the hood light yet
extremely robust. The hood opens and
closes in only 13 seconds and is operable
up to a speed of 50 km/ h (31 mph).
With the hood closed, the car’s profile is
optimised for
aerodynamic performance,
which explains
the low drag coefficient
of 0.30. Wind noise is practically elimi -
nated.
The new, integrated wind deflector
manipulates headwind to create ideal
conditions. Electrically powered and
installed directly behind the passenger
cell, it provides effective protection
against air turbulence.
Twin tailpipes in stainless steel also
make a clear statement. The 20 -inch
Carrera S wheels afford an unobstructed
glimpse of the brake calipers with a
red painted finish. As you would expect,
the 911 Cabriolet offers a high level of
occupant safet y and features an effective
roll-over protection concept as well as
full-size airbags for the driver and front
p a s s e n g e r.
Without question, the new 911 Carrera S
Cabriolet has remained faithful to the
sporty spirit of its predecessors and is
ensuring that the legacy lives on in the
21s t ce n t u r y.

Wheels.
On the new 911, the wheels have been
enlarged by one inch over the previous
model. Not only do the larger wheels
improve dynamic performance, they
also look more imposing.
The new 911 Carrera models are
equipped with 19-inch Carrera wheels as
standard. These are lightweight
alloys featuring a classic sport y design.
Tyre sizes are 235/40 ZR 19 and
285/35 ZR 19 at the front and rear
respectively.
The S models are equipped with light-
alloy 20 -inch Carrera S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to cope with the increased power output
of these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear.
The larger t yre size improves both ride
comfort and track performance. The

rolling resistance of the t yres
has been
reduced by up to 7 % to improve
fuel
economy, while t yre weight and dry brak -
ing distances have also been reduced. A selection of 20-inch wheels is available in
our range of options.
Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) is available
on request. This safet y system sends
warnings to the on-board computer’s
display screen in the event of low t yre
pressure or a gradual or sudden loss
of pressure. The individual pressures
in all four t yres can be displayed in the
instrument cluster.
Porsche Stability Management (PSM).
As standard, the new 911 models

are equipped with enhanced Porsche
Stabilit y Management (PSM), which
maintains stability even at the limits of
dynamic driving performance. Sensors
continuously monitor the direction,
speed, yaw velocity and lateral acceleration
of the car. Using this information, PSM is able to calculate the actual direction
of travel at any given moment. If the car
begins to oversteer or understeer, PSM
applies selective braking on individual
wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake differential
(ABD) and anti-slip regulation (ASR). When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving st yle.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels)
requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of
driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

Electric parking brake.
The new electric parking brake, which
you can activate and deactivate manually,
releases automatically as you pull away.
With the hill-hold function, you can

pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The new 911 models offer advanced
airbag technology in the form of full-size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort to
the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the new 911 models
are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact protec -
tion elements in the doors and t wo air -bags on each side. An integral thorax

airbag is located in each seat side bolster,
while the door panels each contain an
upwards-inflating head airbag. Each
thorax airbag has a volume of 10 litres
and each head airbag 15 litres, ensuring
excellent protection in the event of a
side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera
Cabriolet models have exemplary torsional
rigidit y and flexural strength. Body flexing
is minimal, even on the most poorly sur -
faced roads.
Increased protection is provided by an
automatically deploying roll-over protec -
tion system if the car were to overturn.
Two spring-loaded roll-over bars are
neatly incorporated behind the rear
seats. The roll-over sensor continuously
monitors the car’s pitch and roll, contact
with the road, as well as lateral and
longitudinal forces. If the car were to
overturn, the roll-over bars would be
deployed instantly.

In the 911, there is a point at which all
forces come together. The steering wheel
is the most important inter face bet ween
the driver and the sports car. This is

why all available steering wheels feature
a high-grip steering wheel rim in smooth-
finish leather and offer outstanding
ergonomics. A full -size airbag is integrated
as st a n d a rd .SportDesign steering wheel.
As with the sports steering wheel, the
optional SportDesign steering wheel
is adjustable for both height and reach
and, thanks to its grip mouldings, it’s
in safe hands – even on the sportiest
of drives.
Sports steering wheel.
The sports steering wheel is fit ted as
standard and adjusts up to 40 mm for
height and up to 60 mm for reach.
The optional multifunction steering
wheel has four function but tons and t wo thumbwheels for convenient operation

of audio, telephone and navigation
functions, TFT display and on-board
computer. On request, the steering
wheel is available in smooth-finish leather,
carbon or mahogany. In conjunction with PDK, the steering
wheels are equipped with t wo ergonomic
gearshift switches enabling you to
change gear directly from the steering
wheel. With the optional Sport Chrono
Package, the steering wheel also features
a display above the airbag module to
inform you whether the SPORT, SPORT
PLUS and Launch Control functions have
been activated.

In conjunction with PDK, the steering
wheel features t wo gearshif t paddles.
These are made from a strong alloy and
are ergonomically located behind the
lef t- and right- hand steering wheel
spokes. Pull the right-hand paddle and
PDK shifts up. Pull the left-hand paddle and PDK shifts down. When PDK has
been combined with the optional Sport
Chrono Package, the left- and right-hand
spokes additionally feature a display

that tells you whether the SPORT, SPORT
PLUS and Launch Control functions have
been activated. Steering wheel heating.
For increased comfort on cold days,
steering wheel heating is available as
an option for the sports steering wheel
and multifunction steering wheels
(only in conjunction with seat heating).
The heating is operated by a but ton
on the rear of the lower steering wheel
spoke.
