Like every good story, this one is about
a dream. The dream of re-inventing
a legendary sports car concept and
enhancing it with technology that will
make it fit for the future.
This dream has been occupying our
thoughts for a long time. And like any
great dream, it has stayed with us every
single day – with our engineers, our
designers and also with many Porsche
enthusiasts. And that ’s a good thing,
because any thing is possible when you truly believe in something and are ready
to give your all to achieve it.
That dream has now become realit y.

We have succeeded in uniting the
iconic design of the 911 Targa with an
innovative, fully automatic roof system.
What began as a pledge in 1965 is
now honoured in the form of the
911 Targa with the perfection of a
timeless concept. And the car is set
to become a classic once again. The
st yle- defining classic of tomorrow.
Imagine meeting a childhood sweetheart again.
And discovering they are now even more attractive.
Perfecting the 911 Targa concept.

1514Iconic style | The 911 Targa revolution
At Porsche, design has always been
about much more than good looks.
Design has always had a function too.
Only this way do you become a st yle
icon in automobile design – and remain
a
n influence in that field for decades.
Or at least you do if you take sports
car design seriously.
The 911 Targa has followed this maxim
right from the word go. The roof
construction, for example, took the 1963
911 Coupé to a whole new aesthetic level and featured a safet y concept that
made open-top driving a viable possibility.
But even in the 1960s, the crucial

question was: what do you do with the
roof? And: where do you stow it? Back
then, the solution to this problem was
very
different from today’s. With the new
911

Targa, our solution is a concept
which our engineers call ‘a fully automatic
roof system with innovative kinematics’.
Though its description may sound a little
cumbersome, the roof system itself is
For our designers: a sculpture.
For our engineers: a performance.

any thing but. Based on a complex and
extremely robust engineering solution,
the new system allows the roof to be
opened and closed fully automatically in
a mere 20 seconds when the vehicle is
stationary. When opened, the roof is
stowed away elegantly and neatly behind
the rear seats.
The materials used for the roof are just as
pioneering as the roof concept itself. Two
flat magnesium elements keep the fabric
roof taut, maintaining that unmistakable
911 silhouette. The heated rear window
is manufactured from weight- optimised
laminated safet y glass. Together with the
noise-insulating roof liner, it ensures that
road noise is kept to a minimum when
the roof is closed. A wind deflector is integrated into the
cowl panel frame. When the roof is open,
it perceptibly enhances driving comfort
by protecting against draughts and
reducing wind noise.
The roll- over protection provided by

the Targa bar meets the most stringent
demands in terms of safet y and body
rigidit y. The design is spot on too. It
invokes the classic shape of the original
Targa, as do st yling details such as the
side fins, the aluminium bar trim and the
‘ targa’ logo.
The result is an open-top sports car with
the feel and comfort of a 911 Coupé.
Sculpture perhaps? Yes, certainly. But a
moving one in every sense of the word.

A sports car is defined by its power. A
Porsche by efficient power. And the new
911 Targa 4 models by efficient sport y
power delivered to the road in st yle.
A 3.4-litre 6- cylinder boxer engine with
a power output of 257 kW (350 hp)
accelerates the new 911 Targa 4 from
0 – 62 mph in just 5.2 seconds.
The new 911 Targa 4S is powered by a
3.8-litre 6-cylinder boxer engine with
an output of 294 kW (400 hp). When
combined with the optional Porsche
Doppel kupplung (PDK), this model takes
just 4.6 seconds to reach the 62 mph
barrier.
The enhanced Porsche Traction
Manage ment (PTM) ensures the new
911 Targa 4 models can tackle any t ype
of weather and any t ype of road surface.
It precisely and directly regulates the
distribution of the drive forces to the
front and rear axles (see page 40). A
visible indicator of the all-wheel-drive
system is the seamless taillight strip.
Other distinguishing features include
the wider body and broad rear t yres –
295 mm on the new 911 Targa 4 and
305 mm on the new 911 Targa 4S.
Some choose to regard the new
911 Targa 4 models as design objects.
But their performance potential soon
makes it clear that they are far too good
to be kept just for show.

The 911 concept follows a clear design
idiom which incorporates sloping dynamic
roof lines, accentuated front and rear wings
and round headlights. Together, these
features ensure that the
9 11 is just as
unmistakable now as it was 50 years ago.
It goes without saying that these principles
apply equally to the new 911 Targa. But
the car has the innovative roof concept
to thank for its individual looks and unique
engineering features. The elegantly
rounded rear screen and
the bar lent the original Targa a certain
lightness which
has inspired designers
throughout
the world of vehicle design,
and indeed beyond.
For the new 911 Targa, our designers
sought – and found – a way of directly
expressing both the distinctive individual
st yle of the original Targa and the sport y
performance that characterises the sev -
enth generation of the 911. Consequently,
Fashion changes.
But style endures.

it now features an even flat ter silhouet te,
crisp clean lines and an extended wheel -
base for even greater stabilit y. Above all
else, a revolutionary roof concept
which,
rather than running counter
to the evolved
design idiom of the
9 11, blends with it to
create a harmonious whole. The result is
a design which is
purposely timeless and
yet always current.

In detail: the wide front track which,
together with the flat roof line of the 911,
creates a particularly dynamic front view.
The standard Bi-Xenon headlights feature
round surrounds, thus combining classic
appeal with state-of-the-art engineering.
A profile view reveals that the new
911 Targa 4 models likewise have the
unmistakable silhouette of the 911.
The aluminium trim of the bar with
characteristic fins and ‘ targa’ logo
provide additional stylistic touches.
At the rear, every thing – the st yling, the
appearance, the effect – is crisp and
precise, thanks to the clean lines and slim
LED taillights. They help to accentuate
the horizontal contouring of the rear, an
impression which is lent additional
emphasis by the active taillight strip. The
stainless steel tailpipes are unmistakably
Porsche. A dual-branch design is used for the new 911 Targa 4S. The wide rear
spoiler is extendable which reduces

lift in all driving situations and increases
driving stability.
The new 911 Targa 4 is equipped as
standard with 19-inch wheels, the new
Targa 4S with 20 -inch wheels. The large
wheels enhance the authoritative sport y
presence of the new 911 Targa 4 models
even more. The t yres have a large rolling
circumference for improved comfort
and performance.
We’ll conclude with a quote from
Ferdinand Alexander Porsche, the first
designer of the
9 11: ‘A coherently
designed product requires no adornment’.
That says it all really.

When it comes to a Porsche, it ’s not
just good looks that mat ter, but what
lies beneath. The engine has been the
character-defining feature of every 911
since
1963. And on the new 9 11 Targa 4
models, it ’s no different. The 6- cylinder
boxer engine, positioned low down at the
rear
of the car, succeeds in uniting t wo
characteristics that are normally mutually
exclusive – performance and efficiency.
Only by doing so is it possible to increase
power output whilst simultaneously
reducing fuel consumption and
CO
2 emissions.
At the heart of all this are intelligent
efficiency-enhancing measures such as
the auto start/stop function and direct
fuel injection (DFI).
And then there’s the crucial weight
factor. The engines are of a light-alloy
construction, making them lightweight
and yet structurally rigid. The result

is comparatively low fuel consumption
and a long service life.
Both engines are also equipped with
VarioCam Plus – a two-in-one engine
concept for adjusting the intake cam -
shafts and switching the lift of the intake
valves. This results in instant accele -
ration, exceptional smooth running
performance and an extraordinary
level of tractive power with a compara -
tively low level of fuel consumption.

Efficiency technologies.
At Porsche, reducing fuel consumption is
part and parcel of performance. It goes
without saying, therefore, that efficiency
technologies are standard features on
the 9 11 Targa 4 models and form an
integral part of the vehicle concept.
Whenever the car comes to a stop, the
auto start/stop function automatically
switches off the engine – and restarts it
swiftly and smoothly as soon as you
operate the clutch or, on models with
Porsche Doppelkupplung (PDK), as soon
as you release the brake.
The thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow. The resulting
improvement in combustion efficiency has
a beneficial effect on fuel consumption. A further fuel-saving feature is electrical
system recuperation. This function
ensures that the bat tery is recharged
predominantly by the alternator under
braking conditions.
Direct fuel injection (DFI).
DFI delivers fuel directly into the combus
-
tion chamber with millisecond precision.
The spray and cone angles of the multi-
hole injectors have been optimised for
torque, power output, fuel consumption,
emissions and efficient combustion.
Exhaust system.
The exhaust system of the 911 models
has been redesigned – acoustics included.
The stainless steel exhaust system
comprises two distinctive and independent
exhaust tracts. A selectable t win-tube
sports exhaust system featuring distinc -
tive polished stainless steel tailpipes
is available as an option. Activated by
a but ton, it produces an even more
intensive sports car sound.
