Meetings, conferences, business lunches.
How about some leisure in between?

The 911 Carrera.
In the 21st century, we find ourselves
caught bet ween all kinds of opposites on
a daily basis: bet ween the demands of
our work life and our private life, between
the real world and virtual realit y. How can
they all be reconciled? With a strong iden ­
tit y and a sports car that has incorporated
many contradictory notions since 1963.
Sportiness and everyday practicality
are a prime example. The 911 Carrera is
equipped as standard with direct fuel
injection (DFI) and VarioCam Plus for high
power, high torque, efficient combustion
and, as a result, comparatively low fuel
consumption. Tradition and innovation blend seamlessly
together in the rear
­mounted 3.4 ­litre
flat ­six engine thanks to its downsized
capacity. Despite the reduced displace ­
ment, the engine is capable of delivering
even more power to the road than its
3.6 ­litre predecessor.
The figures speak for themselves. The
maximum power of 257 kW (350 hp) is
available at 7,400 rpm and the maxi ­
mum torque of 390 Nm is generated at
5,600 rpm. Yet, in conjunction with
Porsche Doppelkupplung (PDK), fuel con ­
sumption and CO
2 emissions have been
reduced by 16 % compared with the pre ­
vious model. Even more impressively, the
car accelerates from 0 to 62 mph in
4.8 seconds and reaches a top speed
of 179 mph.
The 911 Carrera generates powerful
forces, which are transmit ted precisely
and directly to the wheels by the 7 ­speed
manual gearbox. As with the optional PDK,
gears 1 to 6 have a sports ratio, while
7th gear has a long ratio for reduced fuel
consumption. The SPORT but ton, which
is fit ted as standard, makes it possible to
select an even more responsive engine
and transmission setup.
In terms of form and function, the single
tailpipes are especially imposing and emit a sound which is t ypically Porsche. The
19
­inch Carrera wheels are fit ted as
standard and improve driving stability
and performance.
Sports car technology as standard, in
the form of black four ­piston monobloc
aluminium fixed calipers, Porsche Stability
Management (PSM) and Bi ­Xenon head ­
lights, shows that sportiness and safety
are not mutually exclusive.
Sport, moderation, everyday practicality
and st yle. Four key themes, one unifying
concept: the 911 Carrera.

When you know your strengths,
it’s easy to acquire new ones.

The new 911 Carrera 4.
One thing is for certain. When it comes
to finding your own strengths, it always
helps to know who you are and where
you come from. Where the 911 is con­
cerned, we call this Porsche identit y.
The immense power that is embodied in
this strong identit y is immediately apparent
in the new all ­wheel ­drive 911 Carrera 4.
Its enhanced Porsche Traction Management
(PTM) converts power directly into motion.
Not in a heav y ­handed way, but intelligently.
Sensors control the rotational speeds of
all four wheels, the vehicle’s lateral and
longitudinal acceleration and the steering
angle. In this way, the active all ­wheel drive can continually respond to different
driving situations and precisely distribute
drive forces bet ween the front and rear
axles. Tuned to provide even more poised
and balanced handling during performance
driving, PTM quickly and clearly
demon ­
strates, especially in the wet and snow,
what we at Porsche understand by traction.
Expressed in simple terms, the new
911 Carrera 4 is self ­assured. An assured ­
ness that has been assisted by engineer ­
ing and aesthetic details such as
the wider
body – the rear wings are 44 mm
wider
than those of the 911 Carrera – the
295 mm wide rear t yres, the special air intakes, the illuminated rear light strip
with taillights and parking light function,
and distinctive sideskirts.
One of its inherent strengths is, of course,
its engine: the 3.4 ­litre flat ­six power unit
delivers 257 kW (350 hp) at 7,400 rpm
and accelerates the new 911 Carrera 4
from 0 to 62 mph in just 4.9 seconds.
Top speed is 177 mph. One strength may
possibly come as a surprise: by
downsiz­
ing the engine, it has been possible to
reduce the fuel consumption and CO
2
emissions by up to 15 % compared with
the previous model.

2 emissions, please refer to pages 143/145.

Let ’s now bring the power of identit y
to bear on the road. With the aid of the
7 ­speed manual transmission or the
optional PDK. Both feature sports ratios
for gears 1 to 6 and a long ­ratio 7th
gear for fuel efficiency.
The 911 has many strengths. The new
911 Carrera 4, with its superlative traction,
dynamic performance and safet y, has
acquired even more. Why not take your
seat behind the wheel and make these
strengths your own?

The long and winding road is where you’d like to be.
Sometimes, it pays to take the direct route.

Transmission.
The 7-speed manual gearbox.
Pure, direct, precise. Short shif t move ­
ments and an optimum transition from
one gear to the next. That ’s exactly what
you would expect of a Porsche manual
gearbox.
What you might not have expected is a
7 ­speed manual gearbox that combines
a high level of sport y performance with
an equally high level of efficiency and
offers extra comfort for longer journeys. It’s an exceptional innovation, and not
only in the sports car segment.
The design of this manual gearbox is
based in principle on that of Porsche
Doppelkupplung (PDK). Gears 1 to 6 have
a sports ratio and top speed is reached
in 6th gear. The additional 7th gear, how
­
ever, has a long ratio, which reduces
torque and helps to reduce fuel consump ­
tion. Lower engine revs at fast driving
speeds also ensure a high level of com
fort
on long stretches of road. In addition
, a gear indicator in the rev counter reminds
you which gear has been selected. The
upshift indicator in the instrument cluster
helps you actively conserve fuel.
Thanks to the elevated centre console,
the gear lever is within easy reach –

ideal for sport y gear changes.
Whether you select a sporty or comfortable
gear, the way you reach your destination
is in your own hands.

Porsche Doppelkupplung (PDK).
Available as an option for all 911 Carrera
models is 7­speed PDK, featuring manu ­
al and automatic modes. It facili
tates
extremely fast gear changes
with no
interruption in the flow of power, whilst at
the same time improving acceleration
and fuel efficiency. In total, PDK has seven gears at its dis
­
posal. Gears 1 to 6 have a sports ratio
and top speed is reached in 6th gear.
7th
gear has a long ratio and helps to

reduce fuel consumption by keeping
engine revs low.
PDK is essentially t wo gearboxes in one
and thus requires t wo clutches. This
double ­clutch arrangement provides an
Porsche Doppelkupplung (PDK)
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.The effect is instant. Driving feels even
sportier and more dynamic, and agility

is increased. Depending on the gearshift
programme (SPORT button activated
Temperament | Transmission
or deactivated), the gear change is opti ­
mised for comfort or for sport y driving.
With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport ­derived gearshif t strategy’
functions (p. 67).
Coasting.
The ‘coasting’ function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent deceler ­
ation caused by engine braking. In this
way, optimum use is made of the vehi ­
cle’s momentum, allowing it to coast for
longer distances.
For example, you may want to slow down
from 62 mph to 49 mph in anticipation
of the change of speed limit ahead. As
soon as you release the accelerator
pedal, PDK deselects the current gear auto
matically and you begin to coast
in neutral until you have reached your
desired speed. The moment you engage
the accelerator or brake pedal, PDK
selects the appropriate gear smoothly
and seamlessly within a fraction of a
second. In short, driving in coasting mode makes
a real impact on fuel consumption without
any need for compromise on comfort or
sporty performance.
Another way to reduce fuel consumption is
to utilise the coasting function on downhill
gradients that are gentle enough for you

to maintain a constant speed. Efficient on
long journeys, such as on the motorway,
PDK remains ready to respond as swiftly
and precisely as you would expect.

It is possible to have a lot of power and
yet not be able to move any thing. Only
by using your power intelligently will you
truly progress – and with consummate
ease.
Enhanced Porsche Traction Management
(PTM) is standard on all 911 Carrera
all ­wheel ­drive models. It is an active all ­
wheel ­drive system with an electronically
variable map ­controlled multi ­plate clutch,
automatic brake differential (ABD) and
anti ­slip regulation (ASR). Drive power is distributed bet ween the
permanently driven rear axle and the
front axle by means of the electronically
variable multi
­plate clutch.
The status 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, includ­
ing 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 begin
to lose traction under acceleration, a
greater proportion of the drive power
is automatically transmit ted to the front
axle by a more positive engagement of
the multi ­plate clutch. In addition, ASR
prevents wheel spin by adapting the
engine’s power output. During cornering,
the optimal level of drive power is dis­
tributed to the front wheels to ensure
excellent lateral stability.

In conjunction with Porsche Stability
Management (PSM), PTM helps to ensure
the perfect distribution of drive power for
optimum traction in most road scenarios,
whether on long straights, through tight
corners, or on surfaces with different
friction coefficients.
Far better than a power struggle
is power interplay.

Electromechanical power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the electromechanical power steering. Statis
­
tics show that a car drives in a straight
line 90 % of the time. Unlike conventional
hydraulic pumps, the electric motor uses
energy only when the steering wheel is
actually turned. The absence of hydraulic
fluid also makes the system more
bene ficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the comfort ­enhancing
power steering system, is available as an
option for the 911 Carrera models. At high
speeds, the steering is as firm as possible,
ensuring maximum precision whilst steer ­
ing comfort remains as high. At low speeds,
the
steering ratio of Power steering Plus
adjusts for much easier manoeuvring and
parking.
SPORT button.
Fit ted as standard, 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 automati ­
cally deactivated. If fitted, the optional
sports exhaust system is also activated
automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available
as an option. This integrated system
provides simultaneous enhancement for
the chassis, engine and transmission.
Included in the package are a performance
display, a digital and an analogue stop ­
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
Every day can be sports day.

Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.
With the hill
­hold function, you can
pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The 911 Carrera models offer advanced
airbag technology in the form of full ­size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort
to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated not just sooner,
but with even greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the 911 models are
equipped as standard with the Porsche
Side Impact Protection System (POSIP).
It comprises side impact protection ele ­
ments in the doors and t wo airbags on each side. An integral thorax
airbag is
located in each seat side bolster,
while
the door panels each contain an upwards ­
inflating head airbag. Each thorax airbag
has a volume of 10 litres and each head
airbag 15 litres, ensuring excellent pro ­
tection in the event of a side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera
Cabriolet models have exemplary torsional
rigidit y and flexural strength. Body flexing
is minimal, even on the most poorly sur ­
faced roads.
Increased protection is provided by an
automatically deploying roll ­over protec ­
tion system if the car were to overturn.
t wo spring­loaded roll ­over bars are
neatly incorporated behind the rear
seats. The roll ­over sensor continuously
monitors the car’s pitch and roll, contact
with the road, as well as lateral and
longitudinal forces. If the car were to
overturn, the roll ­over bars would be
deployed instantly.

Motorsport
It’s hard to say what’s been our most emotional moment on the racetrack.
We have more than 60 years’ worth of them.

Motorsport.
To be able to call upon more than 60 years
of experience as you bat tle for every
hundredth of a second out on the track –
that ’s what Porsche Motorsport is all
about. Our driving force is our teams –
all those people, from driver to engineer,
who work tirelessly on racetracks throug­
hout the world to take us forward. They
have been realising and living one shared
dream for generations: Ferry Porsche’s
dream of a car that could be both vic­
torious on the track and practical on the
road. And from that dream, more than
30,000 victories have ensued to date. Victories achieved, for example, with

the Porsche 956 – one of the most suc ­
cessful race cars of all time. And with
those that continue to show that same
potential,
such as the 911 GT3 RSR and
the 911 GT3 Cup.
Both are race cars that have been suc ­
cessful in circuit and endurance races.
As successful, in fact, as the brand as
a whole. To date, Porsche Motorsport
has built more than 3,000 race cars,
over 1,000 of which are still in use today. They enter amateur and top
­class racing
events, including the American GT races
and the one ­make championships, of
which there are more than 19, the Porsche
Carrera Cup Germany and the Porsche
Mobil 1 Supercup being just t wo. What­
ever the race, there are always new goals
in mind. Take, for instance, the Le Mans
24 Hour race in 2014. That race will see
a prototype, designed completely from
scratch, line up at the start, aiming to
continue the series of 16 overall victories
enjoyed so far at Sarthe. For Porsche, what ’s even more important
than a place on the podium is the experi
­
ence acquired from racing. And the ideas
and visions that come out of that experi ­
ence. All knowledge gained on the race ­
track will get transferred as either design
or test principles to our road cars. Just
like the exhaust gas turbocharger and
double ­clutch transmission technology
did, for instance. This close relationship
be t ween the racetrack and the road is
unique. It allows every Porsche customer
to participate – directly or indirectly – in
the racing experience. It lets them get
a
feel for what drives us. Yesterday, today

and tomorrow: Spirit. Principles. Vision.
