PORSCHE 911 CARRERA 4S 2015 6.G Information Manual

Power steering Plus.
The comfort- oriented Power steering Plus
is available as an option. At low speeds,
it adjusts for much easier manoeuvring
and parking.
Rear-axle steering.
Rear-axle steering is available on request
for all S models. Until now reserved
exclusively for the 911 Turbo and 911 GT3
models, it enhances performance and
everyday practicalit y in equal measure.
For particularly nimble handling combined
with a significant increase in driving
stability.
The advantage for day-to - day driving:
during low-speed manoeuvres, the
system steers the rear wheels in the
opposite direction to that of the front
wheels. This has the virtual effect of shortening the wheelbase. The turning
circle is reduced, cornering turn-in
becomes considerably more dynamic,
and parking is noticeably easier to
manage.
The advantage for sport y driving: during
high-speed manoeuvres, the system
steers the rear wheels in the same
direction as that of the front wheels.
Driving stability is increased by the
virtual extension of the wheelbase and
agility is enhanced by the simultaneous
steering of the front and rear axles. All
this has an impact on maximum driving
performance: an extremely positive one.
Front-axle lift system.
Particularly practical: the lift system,
available as an option for all 911
models,
raises the front end by approximately 40 mm – and keeps it there up to a
speed of roughly 21 mph. With this new
system, kerbs, ramps and car park
entrances are a sporting challenge of the
past.
Porsche Dynamic Chassis Control
(PDCC).
PDCC – optional for all S models in
conjunction with rear-axle steering –
is an active anti-roll system that
suppresses lateral body movement
during cornering manoeuvres. In
addition, it minimises the lateral
instability of the vehicle on uneven
ground.
The results are improved dynamic
performance, even more neutral handling
and increased ride comfort – whatever
the speed. In simple terms, the t yres and vehicle
hold the road bet ter and you can steer
through corners faster and in a more
relaxed manner. Which is why PDCC sets
standards for driving performance, ride
comfort – and driving pleasure.

SPORT button.
The SPORT button enables you to select
a suspension setup where the emphasis
is on either comfort or sport y performance.
At the push of a button, the electronic
engine management system switches the
engine mapping to offer an even sharper
response and engine dynamics that are
more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher engine
speeds and downshifts happen sooner.
In addition, coasting mode and the auto
start/stop function are automatically
deactivated. If fitted, the optional sports
exhaust system is also activated
automatically.
Sport Chrono Package.
Adrenaline at the push of a but ton, goose
bumps included: the functions of the
optional Sport Chrono Package enable
an even sportier tuning of the chassis,
engine and transmission – and launch
you to unprecedented sporty heights.
What ’s new is the mode switch on the
steering wheel, derived from the
918 Spyder to make you feel closer to
the racetrack. Without your hand leaving
the steering wheel, you can choose any
of four set tings: Normal, SPORT, SPORT
PLUS and Individual. Now you can adapt
the vehicle even more to the way you
want to drive. On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the S models, optional
Porsche Dynamic Chassis Control (PDCC)
and optional rear-axle steering adapt for
enhanced roadholding performance by
switching to a sportier damper set ting
and offering more direct turn-in on
entering the corner.
In combination with PDK, the Sport
Chrono Package has three additional
functions. The first is ‘Launch Control’,
which can be used to achieve the best
possible standing start – a racing start.
The second function is the motorsport-
derived gearshift strategy. In this mode,
Another few seconds faster.
Under the skin.
High-performance systems.
PDK is geared up for extremely short
shift times and optimum shift points for
the maximum acceleration available.
This combination of uncompromising and
involving performance is ideal for the
racetrack.
The third function – SPORT Response –
is brand new to the 911. Pressing the
but ton in the centre of the mode switch
primes the engine and transmission for the
fastest possible unleashing of power. In
other words, maximum responsiveness –
for a period of approximately 20 seconds.
A timer graphic in the instrument cluster
tells you how long is left.

Another component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with PCM,
a special performance display enables
you to view, store and evaluate lap times
or other driving times. It shows the total
driving time, lap distance, lap number
and lap times recorded so far. Dynamic engine mounts are also part

of the Sport Chrono Package. The
electronically controlled system
minimises the perceptible oscillations
and vibrations of the entire drivetrain,
particularly the engine, and combines
the benefits of a hard or soft engine mounting arrangement. In short, it
enhances both driving stability and
driving comfort. PSM Sport.
In conjunction with the optional Sport
Chrono Package, PSM is supplemented
by a ‘Sport ’ mode. It allows a significantly
more sporty driving style, with PSM
remaining active in the background. For
a further enhancement to your driving
experience.

PASM sports suspension.
The PASM sports suspension is available
as an option for the S models of the
Coupé and only in conjunction with
20-inch wheels. The ride height is 10 mm lower than with
the PASM suspension. The springs are
harder and shorter, and the anti-roll bars
on the front and rear axles are stiffer.
The front spoiler lip has an even sportier
geometry, the rear spoiler extends even
more. Not only does this further reduce lift at the front axle, it also provides
downforce at the rear axle for improved
aerodynamics and even better performance
– combined with a surprisingly high level
of comfort.

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.
