engine developing 257 kW (350 hp) at
7,400 rpm, which displays superlative
performance.
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
tion and CO
2 emissions figures which
are up to 16 % lower than those of the
previous model.
When it comes to traction, however,
composure and reason prevail in the
form of the further enhanced Porsche
Traction Management (PTM) active all­
wheel­drive system. Working together
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 fair­weather
car: the new 911 Carrera 4 Cabriolet.
Entirely without contradiction, it com­
bines the thrills of open­top 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 3.4­litre flat­six

There’s a lot of emotion in engineering.
Such as that unique cornering feel.

with Porsche Stabilit y Management (PSM),
PTM ensures excellent levels of stability
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 all­wheel­drive 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
9 11 Carrera 4 Cabriolet.

Engines
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.
