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

The 911 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
important to stay calm at all times,

to act with composure and never rashly.
So it ’s reassuring that you can rely

on the handling characteristics of the
911 Carrera 4S.
The Porsche Traction Management

(PTM) active all-wheel- drive system is
particularly dependable, especially

when driving the car at the limits of
performance. To achieve this, our
engineers have travelled right to the
physical boundaries – and extended

them. PTM now ensures that the car is 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 roadholding, with its 44 mm wider
body and broader track by comparison
with the rear-wheel- drive 911 Carrera
models, and with 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
accentuated 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 optional Porsche Doppelkupplung
(PDK), this power unit can accelerate the
car to 100 km/ h in a mere 4.3 seconds.
And continue up to a maximum speed of
297 km/ h.
Nevertheless, the 911 Carrera 4S
demonstrates that this level of
performance needn’t come at the
expense of fuel consumption and CO2
emissions. Fuel-efficient technologies,
such as electrical system recuperation,
For fuel consumption, CO
2 emissions and efficiency class, please refer to pages 141/143.

auto start/stop – both integrated as
standard – and the ‘coasting’ function of
PDK, prove that Porsche is continually
resolving conflicting aims by means of
Intelligent Performance.
Where safety is concerned, the mono -
bloc fixed brake calipers at the front of
the S models 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.

Comfort
Climate control.
The 911 models feature t wo -zone
automatic climate control as standard
with an enhanced ventilation effect and
separate 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 30 –240 km/ h
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- off timer
keeps the day time 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.
