2015 PORSCHE 911 CARRERA 4S ESP

Sports car fascination 9
A big dream has to be fought for. And so
does a bold vision. The next victory?
Rarely does it simply fall into our lap.
Often though, there are innate factors
we must fight against: resistance,
conventions, and rigid pat terns of
thinking.
Whatever we fight for or against, nothing
is achieved without passion, grit and
determination. Ferry Porsche gave
every thing for the sports car of his
dreams. His dream came true. Not
because he hesitated, dwelled or got
lucky. Because he went that extra mile. This attitude is in every Porsche that
we’ve created since 1948. It ’s there in
the smallest part and in every race we’ve
won. It ’s also found in every idea. That ’s
because our engineers are not satisfied
with 100
%. It ’s because they fight. They
fight for that
one crucial percentage point
more. For the one second that means the
difference
between triumph and despair.
For the ‘Dr. Ing.’ in our company name
and for the chance to stir the passion for
the sports car time and time again. To us, it ’s never been about extra
horsepower alone, but about more ideas
per hp. It ’s about engines that are more
efficient, not bigger. It ’s about a design
that follows principles, not trends. It’s
about sports cars that can be driven day
in, day out.
It ’s only when all these things come
together that we can talk of Intelligent
Performance – the core of the Porsche
brand, and of its future. This is what we
are fighting for. Just as we did on day
one. We are fighting for a dream that will
forever be in our heart.
The dream of the sports car.
“In the beginning I looked around and could not find quite the car

I dreamed of. So I decided to build it myself.”
Ferry Porsche

There’s a good reason for looking forward again.
And many a compelling argument.
The highlights of the new 911.

Principle 37
F o r 911 fans it ’s a question of faith, for
tech lovers it ’s an issue of performance:
rear or all-wheel drive?
The answer may turn out differently on
either side, but neither would be wrong.
Those who recognise the rear-driven
variant as being the one true 911
should
consider that the all-wheel drive setup
goes back to the legendary Paris–Dakar
Rally of 1984, when the Porsche 953
based on the 911
wrote its own chapter
in sport – and engineering – history. Fun
in the corners, by the way, is guaranteed
by both drive layouts. Two irreconcilable philosophies? Let’s
discuss a third: the design. The all-wheel
drive 911
models have a 44 mm wider
body, let ting it rest more firmly on the
road. An impression underlined by the
new light strip, especially after dark.
Another hallmark of the all-wheel drive
models: sheer supremacy. In every
corner and at any time of year. Porsche
Traction Management (PTM), the active
all-wheel drive system, varies the drive
force transmit ted to all four wheels as
the situation demands. This helps to
ensure solid roadholding and even bet ter performance. Simultaneously, of course.
In winter. Day in, day out. At the limits of
dynamic driving performance.
Fair-weather cars? The new 911
Ta r g a 4

models are any thing but. Here, the all-
wheel drive marries excellent traction
with excellent aesthetics.
Rear or all-wheel drive? Whatever stance
you take, the most fascinating philosophy
of life is and shall remain the practical
one. At Porsche, this philosophy has been
about the road for well over 60 years.
Even philosophical questions
can be answered with outstanding performance.
Rear-wheel and all-wheel drive.

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.

Drive 51
The essential feature of all 911 all-wheel
drive models: enhanced Porsche Traction
Management (PTM).
Derived from the 911
 Turbo, the
electronically controlled and fully variable
multi-plate clutch distributes drive force
between the permanently driven rear
axle and the front axle even faster and
more precisely than ever before.
The driving state of the vehicle is
continuously monitored so that it is
possible to respond to different driving
situations. Sensors are used to collect a
range of data, including the rotational speed of all four wheels, the lateral and
longitudinal acceleration of the car and
the current steering angle.
If, for example, the rear wheels threaten
to spin under acceleration, a greater
proportion of drive force is transmit ted
to the front by a more powerful
engagement of the multi-plate clutch.
In this way, PTM, working in conjunction
with Porsche Stabilit y Management
(PSM), always ensures the appropriate
distribution of force necessary for
excellent driving performance and
particularly well-balanced handling at

the limit.

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.

Chassis 63
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.
