For every action, there is a reaction.
Good to know that it’s the right one.

A sports car ought to be fast. That’s the

conventional thinking. It is our belief that

a sports car must, first and foremost,

be fast to react. Only then can it find

the right and immediate answer to the

current road condition and your individual

driving style. A direct response is required

on each straight and in every twist and

turn. In other words, a sports car must

6

have the optimum reaction to each and

every action. For whenever one thinks

about speed, one must also consider the

effects of traction and never disregard

the importance of safety.

The 911 all-wheel- drive models put

these theories into practice without

hestitation. Intelligent all-wheel drive

technologies of fer high levels of safety

without compromising the car’s ability

to deliver extraordinary performance.

The body is imposing and wide for

excellent road holding and driving stability,

attributes epitomised by all 911 all-wheel-

drive models. The common principle that

binds them is what we call Intelligent

Performance.

Perfect conditions for aspiring athletes.

911 Carrera 4 and 911 Carrera 4S.

What is it that sets the professionals

apart? Performance that you can rely on

and that is consistent regardless of mood

and weather. True professionals rise to

any occasion and give their best even

when the odds are stacked against them.

The 911 Carrera 4 and the

911 Carrera 4S are two professionals

that perform on the road with pinpoint

accuracy. The 911 Carrera 4 achieves

this with a 3.6-litre horizontally opposed

cylinder engine that delivers a power

output of 254 kW (345 hp), while the S

model is equipped with a 3.8-litre unit

that generates 283 kW (385 hp). The

911 Carrera 4 completes the sprint

from 0 to 100 km/h in 5.0 seconds,

the 911 Carrera 4S in 4.7 seconds.

This power is transmitted to the road

by Porsche Traction Management (PTM),

an all-wheel-drive system that seizes

the initiative and takes full control of the

situation. In conjunction with Porsche

Stability Management (PSM), it creates

the ideal platform for excellent driving

stability and safety as well as out-

standing driving dynamics and agility.

Professionals are also distinguished

by their commanding presence. The

911 all-wheel-drive models are typified

by their particularly imposing body and

stance with a wide rear track and broad

rear tyres. Another characteristic attrib-

ute is the seamless taillight strip and, at

the front, the air intake grilles and slats

with a titanium-coloured paint finish.

Don’t be fooled by their sunny disposi-

tion. The 911 all-wheel-drive models are

not fairweather sports enthusiasts in

any shape or form. They are dedicated,

professional performers through and

through.

When you’re aiming skywards,

Information Provided by:

you need the reassurance of reliable ground control.

911 Carrera 4 Cabriolet and 911 Carrera 4S Cabriolet.

There is no better place to experience

a sense of total freedom than under a

blue sky, breathing in the fresh air and

with the sun shining on your face. And

there is no more reassuring feeling

than having everything under control

and being able to react to any situation.

The 911 Carrera 4 Cabriolet and the

911 Carrera 4S Cabriolet are open to

this way of thinking.

From a technical perspective, both are as

focused on performance as the closed-

top variants. The 911 Carrera 4 Cabriolet

is equipped with a 3.6-litre engine that

produces a maximum torque of 390 Nm

at 4,400 rpm. The S model has a 3.8- litre

unit that generates its maximum torque

of 420 Nm at 4,400 rpm. Excellent road

holding is ensured by Porsche Traction

Management (PTM) and the mechanically

locking rear differential. A safety-enhancing

roll-over protection concept provides

peace of mind.

The dependable chassis, therefore, is a

good starting point and bad weather

need not dampen your sense of freedom.

The fabric hood of the 911 Carrera 4

Cabriolet models is robust yet lightweight

and, like the roof of the Coupé versions,

is integral to forming the classic 911

silhouette. At the rear, the design of the

Cabriolet models is exactly as you would

expect of an all-wheel-drive 911. The

seamless taillight strip is an unmistakable

styling feature and the body, track and

tyres are sporty and characteristically

wide.

In a 911 Carrera 4 Cabriolet, there is no

excuse to let the weather hold you back.

Hood.

Information Provided by:

Wind deflector.

The fabric hood on the Cabriolet models

is light weight and robust. The roof

frame is made from a weight-saving

construction. The glass rear screen is

scratch-resistant and electrically heated

to provide excellent rearward visibility.

A rain channel on the hood reduces

dripping when the doors are opened.

Electrically powered, the hood opens

and closes with a concertina action,

which ensures excellent protection for

the interior lining in all weathers. The

process, which is initiated by a button on

the centre console, takes approximately

20 seconds and the function remains

operable up to a speed of around

50 km/h.

The interior hood lining is made from a

heat-insulating and sound-absorbent

fabric. Even at high speed, this ensures

that you hear almost nothing other than

the characteristic sound of your Porsche.

Provided as standard, the wind deflector

was developed in the wind tunnel for

practically draught-free driving and

minimal wind noise. It can be detached

and folded compactly for easy storage

in the luggage compartment.

Hardtop.

A hardtop is available as an option for

your 911 Carrera 4 Cabriolet model.

It is made from aluminium and is easy

to fit. On the inside, it is lined with a

sound-absorbent fabric that has been

purposefully designed to complement

the interior of your sports car.

unwavering belief in your principles.

911 Carrera 4 GTS and 911 Carrera 4 GTS Cabriolet.

The 911 all-wheel-drive models combine

excellent safety with outstanding driving

dynamics. After all, they observe the

fundamental principle respected by any

Porsche: the principle of performance.

With the 911 Carrera 4 GTS models, we

take things to a higher level. Whether

it’s the closed-top Coupé or the open-

top Cabriolet, these are the sportiest

all-wheel-drive 911 Carrera models that

we’ve ever created.

Both variants are powered by an uprated

3.8-litre flat-six engine with direct fuel

injection (DFI) and VarioCam Plus, which

generates 300 kW (408 hp) at 7,300 rpm,

or 17 kW (23 hp) more than the all-

wheel-drive S models. A top speed

of 302 km/ h is achieved and the

For fuel consumption and CO2 emissions, please refer to page 77.

911 Carrera 4 GTS Coupé completes the

0 to 100 km/h sprint in 4.6 seconds, the

Cabriolet in 4.8 seconds.

How do they transmit this power to the

road? Directly and, for excellent traction

and enhanced dynamic performance,

with Porsche Traction Management (PTM),

Porsche Stability Management (PSM) and

Porsche Active Suspension Management

(PASM) including a ride height reduction

of 10 mm. The 911 Carrera 4 GTS mod-

els always remain true to their principles,

and the sports exhaust system fitted

as standard gives them an outlet to be

heard.

Distinguishing exterior features of the

911 Carrera 4 GTS models include the

dynamically accentuated cooling air

intakes in the front apron and the

additional spoiler lip painted in black,

as well as the wide rear end and rear

track. The most significant, however,

are the seamless taillight strip and the

‘Carrera 4 GTS’ logo.

The 911 Carrera 4 GTS models combine

excellent precision with top-class traction

for uncompromising driving dynamics

and performance levels that you would

other wise expect to find only on the

racetrack. The principle is simple, but

incredibly effective.

Or create some new ones.

911 Targa 4 and 911 Targa 4S.

At the IAA Frankfurt Motor Show in

1965, Porsche unveiled the first ‘safet y

cabriolet’ of its kind – the Targa. Even

then, it was clear that style and dynamics

were not mutually exclusive from safety.

They are part of the same cohesive

whole, a particularly successful one in

our opinion. What’s changed since then?

Not much, at least as far as the principle

is concerned, except perhaps that the

911 Targa models are now even more

comfortable and exhilarating to drive

than ever before.

Closed or open? The electrically operated

glass roof meets your expectations with

millimetre precision. The unit is fully

integrated into the bodywork, which

ensures a high level of body rigidit y

and the distinctive 911 silhouette is

faithfully preserved. The roofline is

further accentuated by the continuous

aluminium trim strip, which arcs from

the A-pillar to the characteristically

pointed rear side windows.

The all-wheel-drive technologies in the

911 Targa 4 unite traction and safety

with agility and dynamic performance.

To do this requires a formidable source

of power. The 3.6-litre engine in the

911 Targa 4 generates 254 kW (345 hp)

at 6,500 rpm, while the 3.8-litre variant

in the S model produces 283 kW

(385 hp) at the same rpm. The force is

immediate. The 911 Targa 4 achieves

0 to 100 km/h in 5.2 seconds, the

911 Targa 4S in 4.9 seconds.

The 911 Targa has captured some

wonderful memories since 1965.

Now it’s looking forward to creating

some new ones with you.

Roof concept.

Information Provided by:

A glass surround without a feeling of

confinement. An open roof that still

provides shelter. The glass roof of the

911 Targa 4 models gives you freedom

of choice, whatever the speed. As soon

as you operate the switch in the centre

console, the glass roof lowers and can

be retracted to any position that you

prefer. The automatically extending wind

deflector reduces wind turbulence and

noise, enabling you to keep the roof

down on long journeys even in damp or

cold conditions.

The glass roof is made from tinted

laminated safety glass. In conjunction

with the electrically operated roll-up

blind, dual protection against strong

sunlight and cold temperatures is

achieved.

The glass rear screen is hinged to

make it easier to stow luggage in the

rear compartment. The screen can be

released either from inside the passenger

compartment or by use of the key

remote. An electric soft closing function

facilitates closing.

In short, the 911 Targa 4 models unite

dynamic performance with extraordinary

functionality and a timeless design.

For us, this is not a contradiction,

but the result of a simple principle:

Intelligent Performance.

Technical cause.
Emotive effect.

Let us begin by describing the effect. The

driving experience in the all-wheel-drive

models is characterised by high perfor-

mance and a direct response. The cause,

on the other hand, can be attributed to

a series of ingenious technical solutions.

At the heart of it all is the engine. The

all-wheel-drive base models are equipped

with a 3.6-litre horizontally opposed

cylinder engine offering 254 kW (345 hp),

while the 3.8-litre unit in the all-wheel-

drive S models develops 283 kW (385 hp)

and the uprated 3.8-litre variant in the

911 Carrera 4 GTS models produces an

even more impressive 300 kW (408 hp).

There is then the use of an intelligent

lightweight construction and efficiency-

enhancing technologies such as DFI and

VarioCam Plus.

Direct fuel injection (DFI).

Information Provided by:

Direct fuel injection (DFI) is fitted as

standard. With millisecond precision, DFI

injects fuel directly into the combustion

chamber by means of electromagneti-

cally actuated injection valves. The spray

and cone angles have been optimised for

torque, power output, fuel consumption

and emissions, thus ensuring homogene-

ous distribution of the air/fuel mixture

and, consequently, efficient combustion.

In the direct injection system, the

EMS SDI 3.1 engine management system

adjusts the injection timing individually

for each cylinder and the injection quan-

tity for each cylinder bank. This optimises

the combustion process and therefore

fuel economy. A hot-film air mass meter

takes care of the airflow, so that the

combustion chambers contain exactly

the right mixture at all times.

For faster heating of the cataly tic con-

verters after a cold start and for greater

torque in the upper load range, dual injec-

tion is implemented at engine speeds of

up to 3,200 rpm and triple injection up to

2,500 rpm. The required quantity of fuel

is distributed to two or three successive

injection processes per cycle.

DFI improves the internal cooling of the

combustion chamber by forming the

mixture directly in the cylinder. This has

made it possible to increase compression

(12.5:1), resulting in more engine power

and even greater efficiency.

VarioCam Plus.

VarioCam Plus is a variable valve timing

system on the inlet side which also

features two-stage valve lift. This helps

to deliver excellent smooth-running

performance and comparatively low fuel

consumption and emissions, as well as

greater power and torque.

The timing of each valve is steplessly and

electrohydraulically controlled by means

of a rotary vane adjuster.

This two-in-one engine concept seam-

lessly adapts in response to driver input.

The result is instant acceleration and

extremely smooth running.

Lightweight design.

The benefits of a light-alloy engine are

reduced weight and lower fuel con-

sumption. The intelligent engine design

achieves further weight savings in

specific areas. A key example is the

complete integration of the camshaft

bearing system into the cylinder heads.

Fuel economy is additionally improved

by consistently low levels of engine

friction and the effective design of the

oil supply system.

Integrated dry-sump lubrication.

Integrated dry-sump lubrication ensures

a reliable supply of oil even when a

sporty driving style 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. This results in an optimised

and on-demand supply of oil for compara-

tively low fuel consumption and exhaust

emissions.

For fuel consumption and CO2 emissions, please refer to pages 75-79.

Intake manifold.

Information Provided by:

The 911 Carrera 4 and 911 Targa 4

models are equipped with a two-stage

resonance intake system, which takes

engine speed into consideration and

increases the intake volume by exploiting

the fact that air oscillates as it passes

through the intake manifold. This produces

higher low-end torque and a flat ter

torque curve.

The entire intake system is made from

lightweight plastic. In the 3.8-litre engine

of the S models, 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.

The 911 Carrera 4 GTS models feature a

variable resonance intake manifold with

six switchable, vacuum -controlled valves.

These valves enable the system to switch

between power- and torque-optimised

geometries for all six air intake tracts to

produce even higher torque in the mid-rev

range. The cooling system has been

adapted to the increased engine output.

Exhaust system.

The stainless-steel exhaust system of the

all-wheel-drive 911 models comprises

two distinctive and independent exhaust

tracts. The catalytic converters are highly

temperature-resistant and heat up rapidly

for effective emissions reduction. Two

Lambda sensors of the stereo Lambda

control circuitr y regulate the composition

of the exhaust gas separately in each

exhaust tract, while another pair monitors

pollutant conversion in the respective

catalytic converters.

A sports exhaust system is fitted as

standard in the 911 Carrera 4 GTS

models and is available as an option

for all other 911 all-wheel-drive models.

It enhances the characteristic Porsche

sound, making it even more powerful and

even more sporty.

Engine management system.

The EMS SDI 3.1 engine management

system ensures optimum engine

performance at all times.

In particular, it controls the position

of the electronic throttle valve (ETC) –

a prerequisite for compatibility with

the Porsche Stability Management (PSM),

which comes as standard. It also regu-

lates all directly engine-related functions

and assemblies to achieve comparatively

low fuel consumption and emissions

as well as high power output and torque

whatever the driving style.

Another important function is the cylinder-

specific knock control. Since the

cylinders never all work under exactly

the same conditions, 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 and loads.

For compliance with EU standards,

the on-board diagnostics provide timely

detection of 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.
