2015 PORSCHE 911 CARRERA 4S fuel

Principle 31
Those who want to win the fight against
time and for efficient power delivery
cannot afford to carry unnecessary bulk.
Light weight construction is therefore
another core principle of the 911.
However, lightweight construction is not
intelligent unless the right material is
used in the right place on the vehicle.
That, too, is Porsche conceptual harmony.
For without body rigidit y, there is no
agility.
Likewise, driving dynamics and ride
comfort are inextricably linked. For the
bodyshell, therefore, our engineers used very thin, but nevertheless extremely
stiff, sheets of steel. Aluminium and
magnesium were used extensively in
areas such as the roof, the underbody,
the front and rear ends, the doors and
wings, and the engine compartment and
luggage compartment lids.
Such material efficiency reduces the
overall weight and, as a result, the fuel
consumption of the vehicle. It ’s what
makes the 911
the lightest sports car in
its segment. And we’re no less proud of
that leading position than we are of any
epoch-making racing victory.
The real opponent is not the other car.
But every single gramme.

Principle 33
T h e 911 was designed to be a pure-bred
sports car from the very start, initially
offering 96 kW (130 hp). As early as
1966, the first S model hit the road with
an engine built for higher compression.
T h e 911
S 2.0 Coupé drove the power
output of the six-cylinder horizontally
opposed engine up to 118 kW (160 hp)
and was the force behind countless race-
going versions of the 911
in motorsport.
This tradition is also followed by the new
911, boasting six cylinders, a displacement
of 3.0 litres and t wo engine variants: one
rated 272 kW (370 hp) and the other –
an S model – offering 309 kW (420 hp). Both engines meet the requirements of
our time. Thanks to their turbocharged
design, they generate more power – with
reduced displacement and lower fuel
consumption.
911 Carrera models and the
911
Ta r g a 4.
Incredible sportiness is the number one
discipline of the 911 Carrera models and
the 911 Targa 4. Turbocharged induction
makes their engine not only more efficient,
but also more powerful. In figures: 272 kW

(370 hp). The high torque of 450 Nm is
available early on at an impressively low
1,700 rpm. A performance promise
delivered to the driver without detour –
across a wide engine speed range.
Fit ted as standard for the first time in all
models: Porsche Active Suspension
Management (PASM), the electronic
damping control system. Further proof
that, when it comes to the 911, it ’s
always about increased performance –
as well as greater comfort.

The base models are equipped with
19-inch alloy wheels. The newly styled
single-tube tailpipes are imposing – just
like the sound.
How to take the 911 principle up a level:
with a simple ‘S’.

Principle 35
911 Carrera S models and the
911 Ta r g a 4 S.
The new S models raise the performance
concept to an even higher level, with a
t win-turbo engine capable of 309 kW
(420 hp). Here, too, a reduction in engine
capacit y and turbocharging has reduced
fuel consumption and increased driving pleasure at the same time. The S models
generate a maximum torque of 500 Nm –
from as low as 1,700 rpm – putting them
ahead of their predecessor once more by
an impressive 60 Nm. Putting you ahead
of the field.
T h e 911 Carrera S models and the
911 Targa 4S are equipped with 20 -inch alloy wheels. Traction is enhanced
by Porsche Torque Vectoring (PT V),
which is fit ted as standard. Porsche
Active Suspension Management (PASM),
the electronic damping control system,
also comes as standard. The new rear-
axle steering and Porsche Dynamic
Chassis Control (PDCC) are available on
request. Increased performance could not be
managed without greater safety.
The S models are therefore equipped
with six-piston aluminium monobloc fixed
brake calipers in red at the front and
four-piston equivalents at the rear.
Another hallmark of the new S models:
twin tailpipes in brushed stainless steel.
Well, ‘S’ does stand for Sport, doesn’t it?

Drive 41
At Porsche, there are no conventions.
Forbidding free thought? That’s forbidden.
The only thing that mat ters is this
question: how can we become even
bet ter? Let ’s put it another way: can we
redefine the limits of engineering? Can
we reconcile apparent contradictions?
Yes, we can. With Intelligent Performance.
The new 911 answers questions about
the future of the sports car with a
quantum leap in performance. By
reducing fuel consumption, but not by
suppressing emotions. By following a
principle that has already changed
every thing once before: in 1974, with the
f i r s t 911
 Tu r b o. Developed completely from scratch, the
six-cylinder twin-turbo engines of the
911
Carrera and Targa 4 models with a
displacement of 3.0 litres embrace this
principle and perfect it in a forward-
l
ooking way. To be more precise:
tremendous acceleration force even in the
low rpm range is supplemented by the
engine map of a 911 Carrera with the high
rev limits t ypical of a sports car. In other
words, high compression and a high engine
speed combined with good modulation of
power output and surprisingly low fuel
consumption, thanks to the reduced
overall displacement.
Expressed in figures, this means an extra
15 kW (20 hp) of power, an extra 60 Nm
of torque and engine speeds of up to
7,500 rpm. And a considerable reduction
in fuel consumption of up to 13 %. The engine of the 911
Carrera and
911
Targa 4 models develops 272 kW
(370 hp). The maximum torque of
450 Nm is available from as low as
1
,700 rpm. With Porsche Doppelkupplung
(
PDK), the 911 Carrera can accelerate
from 0 to 62 mph in only 4.4 seconds
and reach a top speed of 182 mph.
The propulsive potential of the engine in
the S models, featuring upsized
turbochargers and independent exhaust
system, is even more impressive. It
generates a power output of 309 kW
(420 hp) and the maximum torque is a
might y 500 Nm, available from as low as
1
,700 rpm. With Porsche Doppelkupplung
(PDK) and Launch Control, the

911 Carrera S sprints to 62 mph in a
mere 3 .9 seconds. Top speed isn’t
reached until 190 mph.
What cannot be expressed in figures: the
legendary sound of a 911

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.

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.
