engine developing 257 kW (350 hp) at
7,400 rpm, which displays superlative per­
formance. The 0 to 62 mph sprint is
completed in 5.1 seconds, for example.
And it boasts a top speed of 175 mph.
Equally superlative are the fuel consump ­

with Porsche Stability Management
It may come as a surprise to you, but

our engineers are very emotional people.
And clear thinkers. There is no conflict
bet ween these t wo traits. On the contrary,
they are ideal qualifications for those

tasked with the development of a cabrio ­
let that is more than just a fair ­weather
car: the new 911 Carrera 4 Cabriolet.
Entirely without contradiction, it com­
bines the thrills of open ­top driving with
outstanding road holding.
May we now appeal to your emotions?
Here goes. The new 9 11 Carrera 4
Cabriolet is powered by a 3.4 ­litre flat ­six
Strength | The new 911 Carrera 4 Cabriolet
There’s a lot of emotion in engineering.
Such as that unique cornering feel.

The new 911 Carrera 4 Cabriolet.
(PSM), PTM ensures excellent levels of
stabilit y and safet y. So you can give free
rein to your emotions. Even in the wet
and snow.
The new hood of the
9 11 Carrera 4
Cabriolet is able to adapt to the weather
and your mood in precisely 13 seconds.
That ’s all the time it needs to open or
close at road speeds of up to 31 mph.
Magnesium support elements make the
hood light weight, yet extremely rigid and
robust. An integral wind deflector is fit ted
as standard. Electrically powered, it
extends in just t wo seconds. There’s a feeling of pride that the fabric
hood creates the same elegant silhouet te
as that of the
9 11 Coupé models. The
powerful proportions – the body that is
44 mm wider at the rear, the wider rear
track and 295 mm wide rear t yres – are
characteristic of all ­wheel ­drive design.
All this combines to create that unique
Porsche cornering feel.
We think that it ’s bet ter to play out your
emotions than to conceal them. Because
only a weak character shows no feelings
at all. The new

Which vital ingredients do you need to
experience moments of true happiness?
It ’s our conviction, at least, that you need
impressive road holding. Plus safety,
reliabilit y and faith in technology that won’t
let you down when you need it most.
Because only when we have peace of

mind are we truly free.
All these ingredients have been brought
together in the 911 Carrera 4S Cabriolet.
The car, powered by a 3.8 ­litre direct fuel
injection (DFI) engine with a maximum out ­
put of 294 kW (400 hp) at 7,400 rpm,
sprints from 0 to 62 mph in 4.7 seconds
and boasts a top speed of 183 mph.
Strength | The new 911 Carrera 4S Cabriolet
The strength of identity can be measured after all.
In moments of happiness.

The new 911 Carrera 4S Cabriolet.
Bringing additional peace of mind are the
fuel consumption and CO
2 emissions
figures of the new 911 Carrera 4S
Cabriolet, which are up to 14 % lower
than those of the previous model.
The car’s ‘happiness hub’, however, can
be found in the Porsche Traction
Ma na
gement (PTM) active all ­wheel ­drive
control system which has undergone fur ­
ther refinement. As a result, handling is
even more poised and balanced, particu ­
larly when the car is being driven at its
limits.
This makes controlling the car even
easier
and driving much more pleasura ­
ble.
The hood of the new 911 Carrera 4S
Cabriolet lets you open up to the open
road. The fabric hood featuring magne­
sium elements is light weight, yet robust
and extremely rigid. It opens in just
13 seconds at road speeds of up to
31 mph. When closed, it shows off an
aerodynamically optimised silhouette
that has a drag coefficient of just 0.31.
Which is also why you can hear hardly
any wind noise.
You can certainly hear the engine though.
The sound is – and remains – unmistakably
Porsche. Likewise the dimensions:
the car
is 44 mm wider at the rear, has a wide track and is equipped with wide rear
wheels on 20
­inch Carrera S t yres. All
evidence of that strong identit y.
It’s possible, of course, to describe mo ­
ments of happiness. But it ’s far bet ter to
experience them first hand. The new
911 Carrera 4S Cabriolet.

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.

DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the multi­hole
injectors have been optimised for torque,
power output, fuel consumption, emissions
and ef ficient combustion.
With direct injection, the engine manage ­
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This improves the combustion process
and fuel economy. vailing conditions. This results in instant
acceleration, extremely smooth running
and an extraordinary level of tractive
power, but with a comparatively low
level of fuel consumption.
For faster heating of the catalytic converters
after a cold start and optimum torque in
the upper load range, up to three injection
pulses take place per combustion cycle.
DFI improves the internal cooling of the
combustion chamber by having the mix
­
ture prepared directly in the cylinder. This
allows for a higher compression ratio,
which helps to deliver more output at the
same time as enhanced engine efficiency.
Injection is regulated by the electronic
engine management system and emis ­
sions are monitored by the Lambda
sensors.

VarioCam Plus is a two ­in ­one engine
concept for adjusting the intake cam ­

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.
