“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 performance
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 911 identit y. These
include Porsche Stability Management
(PSM), Porsche Active Suspension
Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring (PT V) and
Porsche Torque Vectoring Plus (PT V Plus)
in conjunction with PDK. Porsche Dynamic
Chassis Control (PDCC) is additionally
available as an option for the 911 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 recently 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.

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.

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
low vehicle weight 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 efficiency 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
composite rigidit y, a high degree of
dynamic torsional stiffness, and
especially sporty handling.
The long wheelbase improves comfort as
well as straight-line accuracy and driving
stabilit y at high speeds and in fast
corners.

Hood.
To our engineers, clever and innovative
hood technology is particularly
important. The result we see today is
a flexible fabric hood comprising a fixed
glass rear screen and three integral hood
elements, which are manufactured from
magnesium. This makes the hood highly
robust and, yet, particularly light weight.
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. In the case of the 911 Carrera Cabriolet
models, for example, it ’s as low as 0.30.
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
operated 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 50 km/ h. 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 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.

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 experience
we have gained and transferred it to the
road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine example.
This brake system has already had to
Composure | Safet y
cope with the harshest requirements of
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 diameter
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 fixed 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
conditions. The key advantage of
PCCB is the extremely 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
masses. The consequence is better roadholding
and increased comfort, particularly on
uneven roads, as well as greater agilit y
and improved handling.
The demands of racetrack use mean
that additional maintenance tasks
will be required alongside the routine
maintenance work scheduled as
part of standard maintenance intervals.

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.
