| The 911 Carrera S Cabriolet
Porsche 356, Porsche 550, Porsche Carrera GT, Porsche 918 Spyder:
openness has always been a Porsche tradition.

The 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
911 Carrera S Cabriolet does just that.
That explains what motivates us; so let ’s
describe what drives the car: the 3.8-litre
engine with direct fuel injection (DFI) and
VarioCam Plus, which produces
294 kW (400 hp) at 7,400 rpm. The
911 Carrera S Cabriolet completes
the sprint from 0 to 100 km/ h in just
4.7 seconds and reaches a top speed
of 301 km/ h.
These are impressive performance
figures, founded on the principle that, if
you want to keep moving, you shouldn’t
carry unnecessary weight. This is
precisely why the 911 Carrera S
Cabriolet incorporates the extensive
use of lightweight materials.
The fabric hood plays a crucial role in
this respect. Integrated, supporting
magnesium elements make the hood light yet extremely robust. The hood
opens and closes in just 13 seconds and
is operable up to a speed of 50 km/ h.
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 eliminated.
The 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 safety and features an
effective roll-over protection concept
as well as full-size airbags for the
driver and front passenger.
Without question, the 911 Carrera S
Cabriolet has remained faithful to
the sporty spirit of its predecessors
and is ensuring that the legacy lives
on in the 21st century.

Wheels.
The 911 Carrera models are equipped
with 19-inch Carrera wheels as standard.
These are light weight 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. All-wheel-
drive models are fit ted with even wider
295/35 ZR 19 t yres at the rear.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. All-
wheel-drive models have 305/30 ZR 20
t yres at the rear.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and t yre
weight are all comparatively low, thereby
helping to reduce fuel consumption.
A selection of 20 -inch wheels is available
in our range of options.
Tyre Pressure Monitoring (TPM).
Integrated as standard, Tyre Pressure
Monitoring (TPM) 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 911 Carrera models are
equipped with enhanced Porsche Stability
Management (PSM), which maintains sta -
bilit y even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y 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 diffe
rential
(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 style.
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 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 911 Carrera 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 not just sooner,
but with even greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the 911 models

are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact
protection elements in the doors and t wo airbags 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 irregular
road surfaces.
Increased protection is provided by
an automatically deploying roll-over
protection 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.
