“That can’t be done.”
If ever a sentence gave motivation to sports car designers, this is it.
Chassis and body.
A solid identit y tends to be described
with words like stability, directness or
substance. This might sound a lit tle
serious but, when it comes to the chassis
and body, we think that this is entirely
the right approach.
The best example is the engineered
design. Indeed, dynamic per formance
and ride comfort fundamentally depend
on factors such as vehicle weight, body
rigidity, wheelbase, axle construction
and steering. With the 911, we challenged
our engineers to push the boundaries
of what is possible. Chassis control systems make a key
contribution to the 911 driving experience
and thus to the 9 11 i d e n t i t y. T h e s e
include Porsche Stability Management
(PSM), Porsche Active Suspension
Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring Plus (PTV Plus).
Porsche Dynamic Chassis Control (PDCC)
is additionally available as an option for
the
9 11 Carrera S models.
Yet, there is still scope for improvement
as far as sport y performance is
concerned. The optional Sport Chrono Package triggers an adrenaline rush
at the push of a but ton. Dynamic engine
mounts, until now exclusively reserved
for 911 GT and Turbo models, may not be
capable of breaking the laws of physics
but they do succeed in exploiting them
to their own advantage – and yours.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second,
a vehicle weight saving of up to 65 kg
primarily as a result of the intelligent
lightweight construction. To meet the second requirement, we
employed state
of the art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
partment and luggage compartment lids.
Magnesium, which is a particularly light
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models, the
hood shell elements. Such material effi ciency is key to reducing the overall
weight and, as a result, fuel consumption
of the vehicle.
For the driver, this intelligent blend
of materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration damping
characteristics and particularly high com
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The longer wheelbase improves comfort
as well as straight line accuracy and
driving stabilit y at high speeds and in
fast corners.
Front and rear axles.
The independent suspension at the front
features a light weight spring strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn
in.
The rear axle is equipped with a
motorsport derived multi link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Hood.
Our engineers have completely redeveloped
the hood for the 911 Carrera Cabriolet
models. The result is a flexible roof
comprising a glass rear screen and three
individual and integral hood elements,
which are manufactured from magnesium
and covered in fabric. This makes the
hood highly robust and, yet, particularly
lightweight.
Another benefit is that the hood is
smooth and firm. The fabric remains taut
keeping the familiar 911 lines elegant. A trivialit y? Only if you choose to ignore
the impressively low drag coefficient
of just 0.30 for the 911 Carrera Cabriolet
models. A further feat of Porsche
engineering.
The rear screen is made from glass and
is electrically heated and scratch
resistant to provide excellent rearward
visibilit y. A rain channel on the hood
carries away water to avoid dripping
when the doors are opened.
Electrically powered, the hood is operat
ed using a but ton on the centre console
or via the key remote. It opens or closes in just 13 seconds and remains operable
up to a speed of 31 mph. The concertina
action ensures optimum protection for
the interior lining.
The interior hood lining is made from
a heat insulating and sound absorbing
material. Consistent interior temperatures
and an effective suppression of wind
noise are the perceptible results. Thank
fully, however, even the hood’s sound
proofing properties are no match for
the resonant Porsche sound.
Open, flexible, independent.
The optimum prerequisites for a long-term relationship.

Wheels.
The 911 Carrera models are equipped
with 19inch 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 20inch 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).
Tyre Pressure Monitoring (TPM) is avail
able 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 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 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.

From the start, Porsche has been
synonymous with motorsport. Ever since
1948, when we found our identit y on
the racetrack, we have taken the experi
ence we have gained and applied it to
the road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine example.
This brake system has already had to
cope with the harshest requirements of
Composure | Safet y
motor racing and is fit ted in cars that
compete in demanding events such as
the Porsche Mobil 1 Supercup.
The cross drilled PCCB ceramic brake
discs for the 911 Carrera have a diame
ter of 350 mm front and rear for even
more formidable braking performance. What we’ve discovered from over 30,000 racing victories:
Brake later, finish sooner.
Porsche Ceramic Composite Brake (PCCB).The use of six piston aluminium monobloc
brake calipers on the front axle and four
piston units at the rear – all finished in
yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent.
PCCB enables shorter braking distances
in even the toughest road and race condi
tions. Excellent fade resistance ensures
greater balance when slowing from race
track speeds.
The key advantage of PCCB is the extreme
ly low weight of the ceramic brake
discs,
which are approximately 50 % lighter than
standard discs of similar design and size.
As well as enhancing performance and fuel economy, this represents a major
reduction in unsprung and rotating mass
es. The consequence of this is bet ter
road holding and increased comfort, par
ticularly on uneven roads, as well as
greater agility and improved handling.
Please note that circuit racing, track
day use and other forms of performance
driving can significantly reduce the
service life of even the most durable
brake pads and discs.
As with conventional high performance
braking systems, we recommend that
all brake components be professionally
inspected and replaced where necessary
after every track event.

2 emissions, please refer to pages 143/145.

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 ele
ments 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 pro
tection 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.
t wo springloaded 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.
