There are countless reasons for having intelligent all-wheel drive.
The new 9 11 Carrera 4S.
Steadfastness. Another apparent Porsche
contradiction. But whilst it ’s true that
sports cars are all about movement, about
surging forwards, it ’s even more impor
tant to stay calm at all times, to act with
composure and never rashly. So it ’s re
assuring that you can rely on the handling
characteristics of the new 911 Carrera 4S.
Particularly dependable is the enhanced
Porsche Traction Management (PTM)
active all wheel drive system, especially
when driving the car at the limits of per
formance. To achieve this, our engineers
have travelled right to the physical bound
aries – and extended them. PTM now ensures that the car is even more poised
and balanced and really comes into its
own
when adopting a sport y driving
st yle or travelling in extreme weather
conditions.
At the rear, the car is the personification
of road holding, with its 44 mm wider
body, wider track and road hugging
305 mm wide rear wheels. The seamless
horizontal taillight strip continues the
same st yling language. The all wheel
drive model is also recognisable from the
front thanks to its dynamically accentuat
ed cooling air intakes in the front end. Though the car is practically at one with
the ground, it cannot keep still. This is
unsurprising when it is powered by a
3.8 litre engine developing 294 kW
(400 hp) at 7,400 rpm. When combined
with Porsche Doppelkupplung (PDK),
this power unit can accelerate the car to
62 mph in just 4.3 seconds. And contin
ue up to a maximum speed of 184 mph.
This hasn’t come at the expense of fuel
consumption and CO
2 emissions either.
Figures for the new 911 Carrera 4S are
up to 13 % lower than those of its prede
cessor. Fuel efficient technologies, such
as electrical system recuperation, auto
start /stop – both fit ted as standard – and
the ‘coasting’ function of PDK, prove that
Porsche is continually resolving conflict
ing aims through Intelligent Performance.
Where safety is concerned, the mono
bloc fixed brake calipers at the front
have six pistons instead of four, whilst
the brake pads are 10 % larger. The result
is even shorter braking distances. Proof
that, at Porsche, safet y is an integral
part of performance, not its polar
opposite.
Steadfast through and through.

And it boasts a top speed of 175 mph.
Equally superlative are the fuel consump

When it comes to traction, however,
composure and reason prevail in the
form of the further enhanced Porsche

wheel drive system. Working together
with Porsche Stability Management
It may come as a surprise to you, but
our engineers are very emotional people.

Engines
To give more and take less.
That’s Porsche engineering.
Engines.
You could ask whether the sports car is
still relevant. It would be a good question,
but you might as well ask the same of
dreams.
The answer to both questions lies in the
future or, to be more precise, in the future
of the sports car. In the 911, the future
is already here. The highly efficient, state
ofthe art engines make a considerable
contribution to the comparatively low fuel
consumption, but their sound is still
unmistakably Porsche.
The 911 engines are also unmistakably
sport y thanks to the SPORT but ton fit ted
as st a n d a rd . At the push of a but ton, the engine be
comes tuned for a sharper response
and engine dynamics that are even more
direct.
The 3.4 litre engine of the 911 Carrera
models demonstrates, therefore, that
performance and efficiency need not be
mutually exclusive. Rather, the downsized
engine capacity and increased maximum
torque are the intelli
gent basis by which
power output can be increased in an
environmentally acceptable and sustain
able way. Fuel consumption and CO
2
emissions have been reduced by up to
16 % compared with the previous model. In their search for improved efficiency,
our engineers analysed an extensive series
of engine components. Answers were
found, including rapid heating of the
engine and gearbox to normal operating
temperature after an engine start by the
thermal management system, improved
air induction and extremely effective
direct fuel injection (DFI).
The same principle applies to the 3.8 litre
engine in the 911 Carrera S models.
There has been no change in displace
ment since the previous model, but
po wer output has been increased while
fuel consumption has been reduced by
up to 15 %. Weight is critical to efficiency. This is
why the engines have a lightalloy
construction, making them lightweight
and yet structurally rigid. The result
is comparatively low fuel consumption
and a long service life.
The engine is the intelligent core of our
identit y. What else could the ‘Dr. Ing.’ in
our company name possibly stand for?

A widely held belief about motorsport is
that power is the only thing that mat ters.
From experience, we know bet ter. Extra
horsepower alone has never been enough
to win a single race. Much more important
to us are ideas – ideas that inspire more
intelligent vehicle concepts and more
ef ficient drive systems. The same applies
on the road. It ’s about get ting the most
out of what you’ve got.
Auto start/stop function.
The auto start/stop function is standard
in the 911 Carrera models.
In cars with the manual gearbox, the
engine switches off automatically when,
for example, you stop at traffic lights,
select neutral and release the clutch
pedal. In cars with Porsche Doppelkupplung
(PDK), the engine switches off whenever
you stop and leave your foot on the
brake pedal.
All audio and communication systems
remain switched on and the climate con
trol continues to maintain your selected
temperature. The only differences you
will notice are the silence at the rear and
the fuel saving. As soon as you operate
the clutch or release the brake, the
engine will restart swiftly and smoothly. The auto start/stop function may remain
inactive under particular circumstances,
for example: extreme outside tempera
tures, when the SPORT but ton is selected
or if bat tery charge is low. It is also pos
sible to deactivate the function manually
using a separate but ton on the centre
console.
Thermal management.
The thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow.
In this way, the engine and gearbox reach
their optimum operating temperature
sooner. As a result, fuel consumption is
reduced through increased combustion
efficiency and lubrication performance.
Electrical system recuperation.
The 911 Carrera models are also equipped
as standard with fuel saving electrical
system recuperation technology. The
vehicle bat tery is recharged by the alter
nator, predominantly under braking.
Under acceleration, on the other hand,
the power draw of the alternator is limited
to increase the engine output available
for driving. The electrical systems are
supplied by the electrical energy stored
during the recharging process.

Integrated dry-sump lubrication.
Integrated dr y sump lubrication ensures
a reliable supply of oil even when a
sport y driving st yle is adopted. It also
has additional cooling functions.
The oil tank is located in the engine,
thereby eliminating the need for an
external oil tank, which saves both space
and weight. To reduce power loss and
increase efficiency, an electronically
controlled oil pump supplies the lubricat
ing points inside the engine as and
when required. When demand is low, the
oil pump is operated at reduced power,
thereby saving fuel.
Air intake system.
The resonance intake system increases
the intake volume by exploiting the fact
that air oscillates as it passes through
the intake manifold. The system can
adjust to engine speed. Benefits of this
include higher torque at low engine
speeds and a flat ter torque curve.
The
9 11 Carrera S models operate a t wo
stage
system.
The entire intake system is made from
light weight plastic. In the 9 11 Carrera
model range, the resonator volume of
the air filter housing varies with engine
speed to bring added character to the
engine sound, which becomes much
more powerful at higher rpm.
Exhaust system.
The exhaust system of the 911 Carrera
models has been redesigned, acoustics
included.
The stainless steel exhaust system com
prises t wo distinctive and independent
exhaust tracts. The cataly tic converters
heat up rapidly for effective emissions
reduction.
A selectable t win tube sports exhaust
system featuring distinctive polished
stainless steel tailpipes is available as an
option. Activated by a but ton, it produces
an even more intensive sports car sound.
Engine management system.
The EMS SDI 9.1 engine management
system ensures optimum engine perfor
mance at all times. It controls, for
example, the position of the electronic
throt tle valve (ETC) – a prerequisite for
compati bility with the Porsche Stability
Management (PSM), which comes as
standard. It also regulates all engine
related functions to achieve optimum
fuel consumption, emissions and power
output whatever the driving st yle.
Another function is the cylinder specific
knock control. Since the cylinders never
all work under exactly the same condi
tions, the knock control function monitors
each one separately. The ignition point
is shifted individually, as and when
necessary, to protect the cylinders and
pistons at high engine speeds.
For compliance with EU standards, the
on board diagnostics detect any faults
and defects that may occur in the exhaust
and fuel systems and then notify the
driver immediately. This also prevents
increased pollutant emissions and
unnecessary fuel consumption.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second,
a vehicle weight saving of up to 65 kg
primarily as a result of the intelligent
lightweight construction. To meet the second requirement, we
employed state
of the art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
partment and luggage compartment lids.
Magnesium, which is a particularly light
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models, the
hood shell elements. Such material effi ciency is key to reducing the overall
weight and, as a result, fuel consumption
of the vehicle.
For the driver, this intelligent blend
of materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration damping
characteristics and particularly high com
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The longer wheelbase improves comfort
as well as straight line accuracy and
driving stabilit y at high speeds and in
fast corners.
Front and rear axles.
The independent suspension at the front
features a light weight spring strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn
in.
The rear axle is equipped with a
motorsport derived multi link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Hood.
Our engineers have completely redeveloped
the hood for the 911 Carrera Cabriolet
models. The result is a flexible roof
comprising a glass rear screen and three
individual and integral hood elements,
which are manufactured from magnesium
and covered in fabric. This makes the
hood highly robust and, yet, particularly
lightweight.
Another benefit is that the hood is
smooth and firm. The fabric remains taut
keeping the familiar 911 lines elegant. A trivialit y? Only if you choose to ignore
the impressively low drag coefficient
of just 0.30 for the 911 Carrera Cabriolet
models. A further feat of Porsche
engineering.
The rear screen is made from glass and
is electrically heated and scratch
resistant to provide excellent rearward
visibilit y. A rain channel on the hood
carries away water to avoid dripping
when the doors are opened.
Electrically powered, the hood is operat
ed using a but ton on the centre console
or via the key remote. It opens or closes in just 13 seconds and remains operable
up to a speed of 31 mph. The concertina
action ensures optimum protection for
the interior lining.
The interior hood lining is made from
a heat insulating and sound absorbing
material. Consistent interior temperatures
and an effective suppression of wind
noise are the perceptible results. Thank
fully, however, even the hood’s sound
proofing properties are no match for
the resonant Porsche sound.
Open, flexible, independent.
