engine PORSCHE 911 CARRERA 4S 2015 6.G Information Manual

Drive 43
The stand- out qualities of the new t win-
turbo engines are their extraordinarily
direct responsiveness and wide torque
plateau, reached early in the low end of
the rpm band. Combined with the high
rev limit – and the legendary sound of a
911
six-cylinder horizontally opposed
engine. In short: excellent performance
that feeds back to the driver in an instant.

Turbochargers.
The displacement of the new 911 models
has been considerably reduced with the
aim of cut ting fuel consumption. That ’s
because we more than most as a sports
car manufacturer bear huge responsibility.
Nevertheless, the power output of the
new engines has been significantly increased. Responsible for that are the
turbochargers developed for the 911

completely from scratch.
The drive system is a t win-turbo
configuration. It has two turbochargers
with one charge-air cooling for each
cylinder bank. Both turbos are particularly compact and have been
optimally adapted to the displacement
and power output of the engine. This
construction minimises the inertia of the
drivetrain and improves responsiveness.
The new turbochargers leave the sceptics
in their wake and find a new destination:
unexplored levels of torque. What looks technical on paper has an
unmistakably resonant sound. The sound
of a 911. And a performance that hits the
driver in an instant. In the form of direct
acceleration and visceral forward thrust.
Rather like a ‘ thump’ in the back the
moment the engine unleashes its
unadulterated power.

Active air intake flaps.
The active air intake flaps in the front air
intakes act to reduce fuel consumption
during everyday trips and to achieve
superlative performance on sporty drives.
Already proven on the 918 Spyder,
the
flaps close automatically while the car
is in motion and thereby reduce drag. On demand or in SPORT or SPORT PLUS
mode, the flaps open and help to provide
optimum engine cooling.
This means that cooling air is supplied
only to the extent that it is actually
needed. That’s efficiency. Of the
intelligent kind.

Efficiency-enhancing technologies.
Auto start /stop switches off the engine
when the driving speed falls below 4 mph
under moderate deceleration, such as
when you are approaching a red light. As
soon as you release the clutch or, with
PDK, depress the accelerator pedal, the
engine restarts – swiftly and smoothly.
In conjunction with Porsche Doppelkupplung
(PDK), a coasting function becomes
available where the situation allows.
The engine is decoupled from the
transmission to avoid deceleration
caused by engine braking. In this way,
optimum use is made of the vehicle’s
momentum, enabling it to coast for
longer distances.
Sports exhaust system.
It ’s a first for any Porsche turbocharged
boxer engines, and it ’s a technical
innovation. Available as an option for the
new 911, the sports exhaust system
features t wo cataly tic converters and a
rear silencer, which lead into two centrally
positioned tailpipes. For a look otherwise
more likely to be seen on the racetrack.
For impressive resonance and an intense
sports car sound – typical of the 911.
For 100 % Porsche. And for goose bumps
at the push of a but ton.

7-speed manual transmission.
Pure, direct, precise. Short shift
movements and an optimum transition
from one gear to the next. The 7-speed
manual transmission combines a high
level of sport y performance with fast
gear changes. In conjunction with the
optional Sport Chrono Package, selecting
SPORT or SPORT PLUS mode activates
the dynamic
throttle-blip function, which
ensures the optimum engine speed for
every downshift, a more emotional
driving experience and an impressive
sound.
A gear indicator in the rev counter
reminds you which gear has been
selected. The upshift indicator in the
instrument cluster helps you actively to
conserve fuel.
Porsche Doppelkupplung (PDK).
The optimised 7-speed PDK, featuring
both a manual and an automatic mode, is
available as an option and offers extremely
fast gear changes with no interruption in
the flow of power. And that ’s with even
faster acceleration performance and a
further reduction in fuel consumption.
A first for the 911
models: in manual
mode, the shift direction simulates that
of racing cars and the 911
GT3 models –
to the rear to shift up, forwards to shift
down. For a racetrack driving experience
wherever you are. Gears one to six have a sports ratio, with
top speed being reached in sixth gear.
Seventh gear is ratioed primarily for fuel
economy.
PDK is essentially t wo gearboxes in one.
This double-clutch arrangement provides
an alternating, non-positive connection
bet ween the t wo half gearboxes and the
engine by means of t wo separate input
shafts. The flow of power from the
engine is transmit ted through one half
gearbox and one clutch at a time, while
the next gear is preselected in the
second half gearbox. During a gear
change, therefore, one clutch simply
opens and the other closes at the same
time, enabling gear changes to take
place within milliseconds.
Always a few milliseconds ahead of time.

Electromechanical power steering.
Statistically, a car drives in a straight line
90 % of the time. In light of this, our
engineers identified potential for energy
savings. Unlike the hydraulic pumps of
conventional power steering systems, the
electric motor of the electromechanical
arrangement uses energy only when the
steering wheel is actually turned.
That isn’t to say that you aren’t ideally
prepared for the other 10 %. After all,
this steering system is t ypically Porsche.
It features a variable steering ratio and responds sensitively and directly while
providing customary agilit y, a high level
of comfort and precisely selected
feedback from the road. Our definition

of efficient.

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.

The driver must always know how to get
ahead, without ever losing sight of the
bigger picture. For this reason, every thing
in the interior is geared towards looking
forward: to the car in front, to the next
corner, to the next driving manoeuvre.
That’s possible only when synergies are
created between engineering and design,
and sportiness and comfort. Proof: the
new sports steering wheel with its puristic
design and excellent ergonomics. More
proof: the ascending centre console. The
principle they share: putting the driver
first. The same applies to the suspension
settings and the two-zone air conditioning
system. There shouldn’t be any need to
spend too long browsing one submenu
after another. You should instead be able
to concentrate on what’s important:
driving pleasure.
Five round instruments make a sport y
contribution. Their primary purpose is to
provide information. They do so efficiently
and accurately. And their styling is
typically Porsche, with the rev counter
exactly where you would expect it to be:
in the middle. Technology to help you along the way is
integrated as standard: new Porsche
Communication Management (PCM)
including online navigation module plus
7-inch multi-touchscreen. Thanks to the
Connect Plus module, PCM is also your
gateway to the digital world.
The instrument cluster with 4.6-inch
colour screen provides you with a
continuous stream of data from the
on-board computer, such as trip
mileage, journey time or average fuel
consumption. It also displays the map
of the navigation system together
with real-time traffic information,
You can feel the Porsche tradition here.

And touch the future.
Interior.
delivers various warnings and reminds
you of your chosen communication and
audio set tings.
From pioneering technology to sporty
comfort. Whether it’s leather or Alcantara,
all the materials we use are exquisite
and puristic.
In addition to the choice of Agate Grey,
Black and Luxor Beige for the
interior, there is a wide range of other
personalisation options available,
including two-tone colour combinations
or special colours and materials such
as carbon, aluminium and high-quality
wood.

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.
