There are countless reasons for having intelligent all-wheel drive.

The new 9 11 Carrera 4S.
Steadfastness. Another apparent Porsche
contradiction. But whilst it ’s true that
sports cars are all about movement, about
surging forwards, it ’s even more impor ­
tant to stay calm at all times, to act with
composure and never rashly. So it ’s re ­
assuring that you can rely on the handling
characteristics of the new 911 Carrera 4S.
Particularly dependable is the enhanced
Porsche Traction Management (PTM)
active all ­wheel ­drive system, especially
when driving the car at the limits of per ­
formance. To achieve this, our engineers
have travelled right to the physical bound ­
aries – and extended them. PTM now ensures that the car is even more poised
and balanced and really comes into its
own
when adopting a sport y driving
st yle or travelling in extreme weather
conditions.
At the rear, the car is the personification
of road holding, with its 44 mm wider
body, wider track and road ­hugging
305 mm wide rear wheels. The seamless
horizontal taillight strip continues the
same st yling language. The all ­wheel ­
drive model is also recognisable from the
front thanks to its dynamically accentuat ­
ed cooling air intakes in the front end. Though the car is practically at one with
the ground, it cannot keep still. This is
unsurprising when it is powered by a

3.8 ­litre engine developing 294 kW
(400 hp) at 7,400 rpm. When combined
with Porsche Doppelkupplung (PDK),
this power unit can accelerate the car to
62 mph in just 4.3 seconds. And contin ­
ue up to a maximum speed of 184 mph.
This hasn’t come at the expense of fuel
consumption and CO
2 emissions either.
Figures for the new 911 Carrera 4S are
up to 13 % lower than those of its prede ­
cessor. Fuel ­efficient technologies, such
as electrical system recuperation, auto
start /stop – both fit ted as standard – and
the ‘coasting’ function of PDK, prove that
Porsche is continually resolving conflict ­
ing aims through Intelligent Performance.
Where safety is concerned, the mono ­
bloc fixed brake calipers at the front
have six pistons instead of four, whilst
the brake pads are 10 % larger. The result
is even shorter braking distances. Proof
that, at Porsche, safet y is an integral
part of performance, not its polar
opposite.
Steadfast through and through.
Corner after corner.

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.

Climate control.
The 911 models feature t wo
­zone auto ­
matic climate control as standard with
an enhanced ventilation effect and sepa ­
rate temperature controls for the driver
and front passenger. The available air
conditioning modes are gentle, normal
and strong.
An active carbon filter traps particles,
pollen and odours and an automatic
air ­recirculation function permanently
monitors air quality, reduces humidity

and switches from fresh to recirculated
air when required. A demister function keeps the windows
clear in cold weather. In warmer weather,
a solar sensor helps the climate control

to detect strong sunlight and automatically
compensate for the comfort of both the
driver and front passenger.
HomeLink® (programmable garage
door opener).
As an option, it is possible to have
a programmable garage door opener
integrated into the overhead console.
At the push of a but ton, it controls up
to three different garage doors, lighting
systems or alarm systems.
Many things have practical qualities.
Even more have a sporty function.
And some are just extremely convenient.

Additional comfort and convenience features.
Cruise control.
This automatic speed control function is
available as an option. For greater driver
comfort on long stretches of road, cruise
control operates in the 18–149 mph
speed range and is activated using a but ­
ton on the steering column control stalk.
Light design package.
The optional light design package is both
practical and aesthetically appealing.
It comprises dimmable LEDs in the over ­
head console and in the areas of the
door pulls, door storage compartments,
front foot wells and rear seats.
‘Welcome Home’ lighting.
For convenience, particularly at night,
the ‘Welcome Home’ lighting function
automatically switches on the LED day
­
time running lights for a defined period
whenever the vehicle is opened or
closed using the key remote.
A customisable delayed switch ­of f timer
keeps the daytime running lights, the

taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Adaptive cruise control with Porsche
Active Safe (PAS).
Available as an option, this cruise control
function regulates your speed according
to the distance bet ween your vehicle and
the vehicle in front. A radar sensor moni ­
tors the road ahead up to a distance of
200 m. If you have set a cruising speed but have begun to gain on the vehicle in
front because it is driving more slowly,
this is detected by the radar sensor.
The system now reduces the speed

of your vehicle at a maximum rate of
3.5 m/sec
2 by restricting the throt tle
or by applying the brakes appropriate
to the prevailing situation until the dis ­
tance that you have preset is maintained. Your vehicle will now continue at a
reduced speed. If the other vehicle

decelerates further, adaptive cruise
control will continue to reduce your
cruising speed – even down to a halt. For additional safet y, if the system detects
that the distance from the vehicle in front
is decreasing, it will also prepare your
vehicle for braking by precharging the braking system so that the brake pads
are already in light contact with the
brake discs. However, drivers still have
to perform heavier braking themselves.
As soon as the road ahead clears again,
your vehicle will accelerate back up to
the cruising speed originally set.
If your vehicle approaches the vehicle

in front too quickly, Porsche Active Safe
(PAS) will issue audible and visual warn ­
ings. In addition, the system briefly jerks
the brakes and if necessary initiates
target braking, with any braking pressure
applied by the driver being increased
within certain system limits.
