iconic
style The 911 Targa concept

8
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 anything is possible when you
truly believe in something and are ready
to give your all to achieve it.
That dream has now become reality.
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
style-defining classic of tomorrow.
Imagine meeting a childhood sweetheart again.
And discovering they are now even more attractive.
Perfecting the 911 Targa concept.

One of thes e films featu res the
911 Targ a. It begins in 1965 in Zu ffen-
hausen – whe re else? It was here th at
the origin al Targa with roll- over bars
and removab le folding roo f – Porsche’s
ingenious so lution to A merican safe ty

from the 911 Coupé, the 911 Targa was
developed in response to increasing
demand for a n open-top v ersion of the
911 which coul d also offer t he same
levels of com fort and safe ty as a
closed-top model.
The Targa name alon e is the stuf f of
legends. It or iginates from t he famous
enduran ce race held in Sici ly, the Targa
Florio. The course was notorious for
its tight b ends which th e comparati vely

chalking u p a number of vic tories
in the proce ss. ‘Targa’ means ‘shie ld’
in Italia n and thus the n ame also
became symbolic of the ‘protective
shield’ p rovided by the i nnovative
safety co ncept of the 911 Targ a.
The most distinctive, style-defining
feature of t he Targa is its alumin ium bar
with thr ee fins and ‘t arga’ logo. Over
the years, t his design has lef t a lasting
impressio n on the car’s dr ivers and
fans.
In 1975, the silver bar was rep laced
with a blac k one for the ‘G -series’
version of t he 911 Targa, wh ilst the
subsequen t 964 series saw t he launch
of the firs t all-wh eel drive 911 Targa. In
1995, for the fourt h generation o f the
911, t he Targa got a completely n ew
roof concept : an electric ally operat ed
glass roof wi th alumini um trim str ips
running along the sides. Even though
this form of t he 911 Targa underwen t
further evolutionary development in
subsequen t generation s, its styl istic
integrity was maintained, resulting in
an award- winning de sign which conv eyed
a feeling of op en-top dr iving, even wi th
the roof clos ed.
The capti vating saga of t he 911 Targa
continues, even today. This current

1514 Iconic 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 style
icon in automobile design – and remain
an 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 safety 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.
The 911 Targa revolution.

1716 Iconic style |The 911 Targa revolution
anything 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 safety 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 safety and body
rigidity. The design is spot on too. It
invokes the classic shape of the original
Targa, as do styling 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 sporty
power delivered to the road in style.
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
Doppelkupplung (PDK), this model takes
just 4.6 seconds to reach the 62 mph
barrier.
The enhanced Porsche Traction
Management (PTM) ensures the new
911 Targa 4 models can tackle any type
of weather and any type 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 tyres –
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 911 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
style of the original Targa and the sporty
performance that characterises the sev-
enth generation of the 911. Consequently,

it now features an even flatter silhouette,
crisp clean lines and an extended wheel-
base for even greater stability. Above all
else, a revolutionary roof concept which,
rather than running counter to the evolved
design idiom of the 911 , 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, everything – the styling, 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 sporty
presence of the new 911 Targa 4 models
even more. The tyres 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 911 : ‘A coherently
designed product requires no adornment’.
That says it all really.

The interior of a 911 doesn’t follow
a particular fashion. It follows clear
principles.
Principles which also apply to the
new 911 Targa 4 models. Here, the
predominantly sporty interior design is
successfully combined with a classic
layout and high-quality equipment.
There are no distractions, no gadgets;
everything is focused on the driver and
on driving. This is the only way of
creating what you could call a sporty
style – you could even say it’s the
very art of sports car design.
These principles are expressed in
practice by the ascending centre
console. Its sophisticated ergonomic
design utilises a clear operating logic
for its controls, such as those for the
individually adjustable two-zone air
conditioning system or for operating
the roof.
Sporty. Classic. Elegant.
It’s wonderful when all styles unite in harmony.

The five round instruments with rev
counter in the middle are timeless, whilst
the instrument cluster, with high-resolution
4.6-inch colour screen displaying naviga-
tion instructions or information from,
for example, the adaptive cruise control
function, the all-wheel-drive system or
navigation system, is state-of-the-art.
The materials used are both high quality
and stylish. The steering wheel rim, door
closing handles, armrests and sections
of the seats are in leather. In addition to
the choice of standard colours – namely
Black, Platinum Grey, Luxor Beige and
Yachting Blue – a wide range of other
personalisation options are available for
the interior, including two-tone colour
combinations and special colours, along
with materials such as carbon, aluminium
and wood.

When it comes to a Porsche, it’s not
just good looks that matter, but what
lies beneath. The engine has been the
character-defining feature of every 911
since 1963. And on the new 911 Targa 4
models, it’s no different. The 6-cylinder
boxer engine, positioned low down at the
rear of the car, succeeds in uniting two
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
CO2emissions.
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.

The 3.4-litre engine of the
911 Targa 4.
The engine of the new 911 Targa 4
develops 257 kW (350 hp) at 7,400 rpm
and a maximum torque of 390 Nm at
5,600 rpm. When combined with the
7-speed manual gearbox, it accelerates
from 0–62 mph in just 5.2 seconds and
reaches a top speed of 175 mph.
The 3.8-litre engine of the
911 Targa 4S.
On the S model, the figures speak for
themselves: the 3.8-litre boxer engine
develops 294 kW (400 hp) at 7,400 rpm
and a maximum torque of 440 Nm at
5,600 rpm. When equipped with the
optional Porsche Doppelkupplung (PDK),
the new 911 Targa 4S completes the
0–62 mph sprint in just 4.6 seconds
and can continue on to a top speed of
182 mph.
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 911 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 battery 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 twin-tube
sports exhaust system featuring distinc-
tive polished stainless steel tailpipes
is available as an option. Activated by
a button, it produces an even more
intensive sports car sound.

7-speed manual gearbox.
Pure, direct, precise. Short shift move-
ments and an optimum transition from
one gear to the next. The 7-speed
manual gearbox, fitted as standard on
the new 911 Targa 4 models, combines
a high level of sporty performance with
an equally high level of efficiency and
offers extra comfort for longer journeys.
A gear indicator in the rev counter reminds
you which gear has been selected. The
upshift indicator in the instrument cluster
helps you actively conserve fuel.
Porsche Doppelkupplung (PDK).
Available as an option for all new
911 Targa 4 models is 7-speed PDK
featuring manual and automatic modes.
It facilitates extremely fast gear
changes with no interruption in the
flow of power, while at the same time
improving acceleration.
Form follows function.
At lightning speed in the case of a Porsche.
Gears 1 to 6 have a sports ratio and top
speed is reached in 6th gear. In 7th gear,
the ratio is designed primarily to reduce
fuel consumption.
Thus PDK combines sporty performance
with efficiency and comfort – in typical
Porsche style.

Coasting.
The coasting function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent deceler-
ation caused by engine braking. In this
way, optimum use is made of the vehicle’s
momentum, allowing it to coast for longer
distances.
For example, you may want to slow down
from 62–49 mph in anticipation of the
change of speed limit ahead. As soon as
you release the accelerator pedal, PDK
automatically deselects the current gear
and you begin to coast in neutral until you
have reached your desired speed. The
moment you engage the accelerator or
brake pedal, PDK selects the appro priate
gear smoothly and seamlessly within a
fraction of a second.
Another way to reduce fuel consumption
is to utilise the coasting function on
downhill gradients that are gentle enough
for you to maintain a constant speed.
Efficient on long journeys, such as on
the motorway, PDK remains ready to
respond as swiftly and precisely as you
would expect.

Sports car aesthetes will love this topic.
Because it’s all about curves. And sport.
And the enhanced Porsche Traction
Management (PTM) is in control of both.
Fitted as standard, PTM is an active all-
wheel-drive system with an electronically
variable map-controlled multi-plate clutch,
automatic brake differential (ABD) and
anti-slip regulation (ASR).
Drive power is distributed between the
permanently driven rear axle and the
front axle by means of the electronically
variable multi-plate clutch. The status of
the vehicle is continuously monitored so
that it is possible to respond to different
driving situations. Sensors are used to
collect a range of data, including the
rotational speed of all four wheels, the
lateral and longitudinal acceleration of
the car and the current steering angle.
If, for example, the rear wheels begin to
lose traction under acceleration, a greater
proportion of the drive power is automat-
ically transmitted to the front axle by
a more positive engagement of the multi-
plate clutch. In addition, ASR prevents
wheel spin by adapting the engine’s power
output. During cornering, the optimal
level of drive power is distributed to the
front wheels to ensure excellent lateral
stability.
In conjunction with Porsche Stability
Management (PSM), PTM helps to ensure
the perfect distribution of drive power for
optimum traction in most road scenarios,
whether on long straights, through tight
corners, or on surfaces with different
friction coefficients.
There’s one thing that unites engineering and design:
an extraordinary fascination for curves.
