2015 PORSCHE 911 CARRERA 4S weight

Design 21
Design of the 911 Targa and
911
Cabriolet.
A legend of the 911 range, a classic, a
sports car dream – ‘the Targa’ always
will have a special place at Porsche.
Conceived 50 years ago as a ‘safet y
cabriolet’, the Targa gained its reputation
as a design icon thanks to its st yle-
defining roll bar. With the innovative fully
automatic roof system now in its seventh
generation, our engineers have seen the
Targa idea mature into a technical
masterpiece.
The roll bar, adorned with the ‘targa’ logo
underneath the side gills, and the
gracefully rounded rear screen bestow
the new 911
Targa 4 models with a
timeless elegance. Their engineering hallmark is the
inclusion of all-wheel drive as standard.
For added driving stability, reflected also
in the design, the body is 44 mm wider –
an impression accentuated by the
seamless light strip on the rear end.
Roof closed, the new 911
Targa displays
the profile of its 911
counterpart, whilst
offering the comfort of a Coupé. Open
the roof and the 911
Targa comes into its
own: a st yle icon that transcends fashions,
rich in tradition – even richer in future.
The new 911
Cabriolet models have also
always been characterised by open
virtues. Made for civilised cruising on
the coastal road, but also for some
sport y corner chasing in the mountains. Here, just like there, they excel with
powerful forward thrust, great agilit y,
and anticipation aplent y on every inch of
tarmac.
What does that have to do with design? A
great deal, because not only does the
innovative fabric hood capture the
elegance of a 911
Coupé silhouette, the
low drag coefficient and use of light weight
materials also mean that the 911 Cabriolet

models come uncannily close to matching
the performance of a closed-top 911.
Form and function once again working as
one. In a particularly aesthetic way.

Design 23
Hood.
The fabric hood of the 911 Cabriolet
models has a fixed glass rear screen and
three integral elements manufactured
from magnesium. Together, these make
the hood highly robust and, yet,
particularly lightweight. It’s also smooth
and firm, the fabric is kept taut, and the design line is elegant. The hood opens or
closes in around 13 seconds, up to a
speed of 31 mph.
The interior hood lining is made from a
heat-insulating and sound-absorbing
material, resulting in perceptibly
consistent interior temperatures and an effective suppression of wind noise.
Thankfully, however, even the hood’s
soundproofing properties are no match
for the resonant Porsche sound.
The new 911 Cabriolet models are also
equipped as standard with an electrically
powered wind deflector, which offers practically draught-free driving and
minimal wind noise with the top down.

Principle 31
Those who want to win the fight against
time and for efficient power delivery
cannot afford to carry unnecessary bulk.
Light weight construction is therefore
another core principle of the 911.
However, lightweight construction is not
intelligent unless the right material is
used in the right place on the vehicle.
That, too, is Porsche conceptual harmony.
For without body rigidit y, there is no
agility.
Likewise, driving dynamics and ride
comfort are inextricably linked. For the
bodyshell, therefore, our engineers used very thin, but nevertheless extremely
stiff, sheets of steel. Aluminium and
magnesium were used extensively in
areas such as the roof, the underbody,
the front and rear ends, the doors and
wings, and the engine compartment and
luggage compartment lids.
Such material efficiency reduces the
overall weight and, as a result, the fuel
consumption of the vehicle. It ’s what
makes the 911
the lightest sports car in
its segment. And we’re no less proud of
that leading position than we are of any
epoch-making racing victory.
The real opponent is not the other car.
But every single gramme.

Wheels.
T h e 911 Carrera models and the
911
Targa 4 are equipped with 19-inch
wheels. These are lightweight alloys
featuring a classic sport y design. All S models are equipped with 20 -inch
alloy wheels. The visual effect is sport y
and dynamic. The t yres are wider to
cope with the increased power output of
these models.
The large wheel size improves traction
and track performance. Rolling resistance

and t yre weight are comparatively low,
which helps to reduce fuel consumption. A selection of 20 -inch wheels is available
in our range of options.
1 19 - inch Carrera wheel
2 20 - inch Carrera S wheel
3 20 - inch Carrera Classic wheel
4 20 - inch RS Spyder Design wheel
5 20 - inch Carrera Spor t wheel

Safety and environment 69
We want to speed everything up. Progress
included. The same applies to negative
acceleration. That’s because even brakes
are a source of potential. So we’ve upsized
the brake system of the new 911 to match
the increased power output.
T h e 911
Carrera base models are fit ted
with newly developed four-piston
aluminium monobloc fixed calipers with
a black anodised finish. All brake discs
have a diameter of 330 mm.
The S models are equipped with red six-
piston aluminium monobloc fixed brake
calipers at the front and four-piston equivalents at the rear. The brake
chambers at the front axle are now
made from aluminium. Brake disc
diameters are 350 mm at the front,
330 mm at the rear. For enhanced
stability and braking performance.
On all models, the brake calipers have an
enclosed monobloc construction. This
makes them tougher but light weight 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 improved wet braking
and optimum cooling.
Porsche Ceramic Composite Brake
(PCCB).
Proven in motorsport, the Porsche
Ceramic Composite Brake (PCCB) is
available as an option. On the new 911,
the cross-drilled ceramic brake discs of
PCCB now have a diameter of 410 mm at
the front and 390 mm at the rear –
for even more formidable braking
performance.
Originating from the 911
 Turbo S, PCCB
features six-piston aluminium monobloc
fixed brake calipers on the front axle and
four-piston units at the rear – all painted
in yellow – to provide braking forces that
are considerably more powerful and,
crucially, are exceptionally consistent.
For Ferry Porsche, even then standing still was unthinkable.
With one exception.
Brakes.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Safety under high-speed
braking is also improved thanks to its
excellent fade resistance.
Another advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of a
similar design and size. This results in
better roadholding and increased comfort,
particularly on uneven roads, as well as
greater agilit y and a further improvement
in handling.

Safety and environment 75
In an era of intensifying debate about
global climate change and CO2 emissions,
every automotive manufacturer is asking
what it has to offer right now. Our
answer? Excellent performance together
with excellent efficiency.
Emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission
values in their respective category.
This is accomplished, on the one hand,
with the efficient use of fuel by means of
efficiency-enhancing technologies such
as auto start /stop, thermal management, electrical system recuperation, active air
intake flaps and, in conjunction with
Porsche Doppelkupplung (PDK), coasting
mode. On the other hand, cataly tic
converters with stereo Lambda control
circuits provide efficient emission
control. Fuel economy and recycling.
Intelligent lightweight construction is
integral to the Porsche identit y. This
is expressed in the form of a high
proportion of aluminium, magnesium,
plastics and super-high-strength
sheet steels. All materials have been
strategically selected, and the paints
used are predominantly environmentally
friendly water-based paints. Each lightweight material is easily recyclable
and all plastic components are labelled
to facilitate future separation for
recycling. In all, the 911
is up to 95
%
recoverable.
Fuel.
All Porsche models – including the 911 –
are designed to operate on fuels with an
ethanol content of up to 10 %, e.g. ‘E10’.
Ethanol has a positive impact on the CO2
balance because it is derived from plants
that absorb CO
2 from the atmosphere.
For others, it’s the order of the day.
For us, the order of the future.

Sports steering wheel.
Fit ted as standard, the sports steering
wheel with spoked design is light weight
and functional. The small centre pad and
the chrome ring encircling the Porsche
Crest – both derived from the steering
wheel of the 918 Spyder – reinforce its
sporty character.
In conjunction with PDK, the sports
steering wheel features two alloyed
gearshift paddles. The shift throw of the
paddles has been reduced, gearshifts
are even crisper. Available as an option
is the new GT sports steering wheel. This
has a smaller diameter. The decorative
ring and the paddles are finished in
Galvano Silver, while the spoke trims are
screw-fastened. For a motorsport-derived
design? Definitely. Above all, though, to
emulate a motorsport driving feel.
Heating and multifunction controls are optionally available for all steering wheels.
These give you fingertip access to the
colour display, the on-board computer
and many audio, telephone and navigation
functions.

Light design package.
The optional light design package is both
practical and aesthetically appealing. It
comprises dimmable LEDs in the overhead
console and in the areas of the door
handles, door storage compartments,
front foot wells and rear seats.
Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your
pocket. As soon as you grab the door
handle, or your hand nears the Porsche
Crest on the luggage compartment lid, the system automatically checks the
encrypted access code on the key. Once
the key is validated, the door or the
luggage compartment lid unlocks. The
engine can then be started and switched
off using the electronic ignition switch.
