Iconic style | The 911 Targa evolution
Over the course of a lifetime, we gather
a lot of memories, some of which play
out in our minds like films. With emotion
in stereo and Technicolor images of
forms and role models which have left
a lasting impression on us.
One of these films features the
9 11 Ta r g a . It begins in 1965 in Zuffen -
hausen – where else? It was here that
the original Targa with roll- over bars
and removable folding roof – Porsche’s
ingenious solution to American safet y
regulations – was created. Derived
from the 9 11 Coupé, the 9 11 Targa was
developed in response to increasing
demand for an open-top version of the
9 11
which could also offer the same
levels of comfort and safet y as a
closed-top model.
The Targa name alone is the stuff of
legends. It originates from the famous
endurance race held in Sicily, the Targa
Florio. The course was notorious for
its tight bends which the comparatively
compact Porsche race cars of the 60s
were able to use to their advantage,

chalking up a number of victories
in the process. ‘Targa’ means ‘shield’
in Italian and thus the name also
became symbolic of the ‘protective
shield’ provided by the innovative

safet y concept of the 9 11 Ta r g a .
The most distinctive, style-defining
feature of the Targa is its aluminium bar
with three fins and ‘ targa’ logo. Over
the years, this design has left a lasting
impression on the car’s drivers and
fans. In 1975, the silver bar was replaced
with a black one for the ‘G -series’

version of the 911 Targa, whilst the
subsequent 964 series saw the launch
of the first all-wheel drive 911 Targa. In
1995, for the fourth generation of the
911, the Targa got a completely new
roof concept: an electrically operated
glass roof with aluminium trim strips
running along the sides. Even though
this form of the
9 11 Targa underwent
further evolutionary development in
subsequent generations, its st ylistic
integrity was maintained, resulting in an award-winning design which conveyed
a feeling of open-top driving, even with
the roof closed.
The captivating saga of the 911 Targa
continues, even today. This current

episode features the return of the iconic
Targa bar, innovative roof technology,
that very special open-air driving
sensation and an exceptional level of
comfort. Once again, it is being played
out on the road. And the ending? Well,
that ’s been left open, of course.

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.
Fit ted 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 bet ween 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 transmit ted 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.

Porsche Dynamic Chassis Control
(PDCC).
PDCC – available as an option for the
new 911 Targa 4S – is an active anti-roll
system that suppresses lateral body
movement during cornering manoeuvres.
In addition, it minimises the lateral
instabilit y of the vehicle on uneven ground.
The results are improved dynamic perfor-
mance and increased ride comfort at all
speeds, as well as optimised turn-in and
stable load transfer characteristics. In simple terms, the t yres and vehicle
hold the road bet ter and you can steer
through the corners faster and in a more
relaxed manner. PDCC is thus set ting
standards for handling performance, ride
comfort and driving pleasure.
Electromechanical power steering.
It ’s a known fact that a stretch of straight
road heightens your anticipation of the
next bend. However, statistics show that
a car drives in a straight line 90
% of
the time. Our engineers saw the energy-
saving potential that this offered. So,
unlike conventional hydraulic pumps, the electric motor of the electromechanical
power steering system uses energy

only when the steering wheel is actually
turned. The absence of hydraulic fluid
also makes the system more beneficial
to the environment.
As far as the other 10 % is concerned,
we’re optimally prepared, as the steering
system is t ypically Porsche. It features
a variable steering ratio and responds
sensitively and directly whilst providing
customary agilit y, a high degree of
comfort and precisely selected feedback
from the road.

SPORT button.
Exceptional design and a sport y character
are not mutually exclusive, as the SPORT
but ton proves. It enables you to select a
suspension setup where the emphasis is
on either comfort or sport y performance.
At the push of a but ton, the electronic
engine management system switches the
engine mapping to offer an even sharper
response and engine dynamics that are
more direct. In vehicles with
Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen
sooner. In addition, coasting mode

and the auto start/stop function are
automatically deactivated. If fitted, the
optional sports exhaust system is also
activated automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available as an

engine and transmission. Included in
the package are a performance display,
a digital and an analogue stopwatch and
the SPORT PLUS but ton. An additional
display in the steering wheel and instru
-
ment cluster indicates whether the
SPORT but tons and Launch Control have
been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the new 911 Targa 4S,
the optional Porsche Dynamic Chassis
Control (PDCC) switch to a harder damping set ting and offer more direct steering
and, therefore, better road holding.
In combination with PDK, the Sport Chrono
Package has two additional functions:
‘Launch Control’, which can be used on the
track to achieve the best possible stand -
ing start, and the ‘motorsport-derived
gearshift strategy’ featuring extremely
short shift times and optimum shift
points for maximum acceleration.

Dynamic engine mounts.
The dynamic engine mounts are included
as part of the Sport Chrono Package. The
electronically controlled system minimises
the oscillations and vibrations of the entire
drivetrain, especially the engine, and
combines the benefits of a hard or soft
engine mounting arrangement.
The stiffness and damping properties
of the engine mounts are adapted to
changes in driving st yle and road surface
conditions. Handling is noticeably more
stable under load change conditions and
in fast corners. Whenever a less asser -
tive driving st yle is adopted, the dynamic
engine mounts provide a greater level
of comfort.
Wheels.
The 9 11 Targa 4 is equipped with 19-inch
wheels as standard. These are light-
weight alloys featuring a classic sport y
design. Tyre sizes are 235/40 ZR 19

and 295/35 ZR 19 at the front and rear,
respectively.
For fuel consumption and CO
2 emissions, please refer to page 103. The S model is equipped with light-alloy
20-inch wheels as standard. The visual
effect is sport y and dynamic.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and
t yre weight are all comparatively low.
Porsche Stability Management (PSM).
As standard, the new 9 11 Targa 4 models
are equipped with
Porsche Stability
Management (PSM) which maintains
stabilit y even at the limits of dynamic
driving performance.
Sensors continuously monitor the direc -
tion, speed, yaw velocit y and lateral
acceleration of the car. PSM uses this
information to calculate the actual

direction of travel at any given moment. If
the car begins to oversteer or under -
steer, PSM applies selective braking on
individual wheels to restore stability.

Under acceleration on wet or low-grip road
surfaces, PSM improves traction using
the automatic brake differential (ABD) and
anti-slip regulation (ASR). The result is a
high level of driving stabilit y and safet y
combined with extraordinary agility.
Porsche Torque Vectoring (PTV and
PTV Plus).
PTV in conjunction with the manual
gearbox, or PT V Plus with Porsche
Doppelkupplung (PDK), are available as
options for the new 911 Targa 4 and
are standard on the new 9 11 Targa 4S.
Both systems actively enhance vehicle
dynamics and stabilit y by braking the
rear wheels as the situation demands.
In addition, a mechanical (PT V) or elec -
tronic (PT V Plus) rear-axle differential
lock is responsible for infinitely variable
torque distribution.
When the car is driven assertively into
a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, a greater amount of drive force is distributed to the outside rear wheel,
inducing an additional rotational pulse
(yaw moment) around the vehicle’s

vertical axis. This results in a direct and
sport y steering action as the car enters
the corner.
At low and medium vehicle speeds, PT V
and PT V Plus significantly increase agilit y
and steering precision. At high speeds
and when accelerating out of corners,
the rear differential lock ensures greater
driving stability. Whichever system is
fitted, it interacts with Porsche Stability
Management (PSM) to improve driving stabilit y on a range of surface conditions,
including the wet and snow.

Brakes.
The new 911 Targa 4 is equipped front
and rear with anodised black four-piston
aluminium monobloc fixed calipers. All
brake discs have a diameter of 330 mm.
Braking performance.
Yet another feat of engineering.
Authentic style | Safety
The new 911 Targa 4S features red six-
piston aluminium monobloc fixed calipers
at the front and four-piston aluminium
monobloc fixed callipers at the rear.

The brake disc diameter is 340 mm at
the front and 330 mm at the rear. The
results are enhanced braking performance
and stability. On both models, the brake calipers have
an enclosed monobloc construction.
This makes them tougher but lighter and
enables sensitive response behaviour,
even under extreme loads. The pedal
travel is short and the biting point
precise. The brake discs are cross- drilled
for bet ter performance in the wet.

The new 9 11 Targa 4 models are equipped
as standard with Bi-Xenon headlights
including a headlight cleaning system and
dynamic range control. The LED front
light units incorporate direction indicators,
day time running lights and position lights.
Cut ting- edge LED technology is also used
for the taillights. LEDs provide better
illumination and respond more quickly to
driver input. In the event of sudden braking, the adap
-
tive LED brake lights begin to pulsate. If
the vehicle is braked to a halt, the hazard
warning lights will switch on automatically.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System (PDLS)
is available as an option. Its dynamic
cornering light function swivels the head -
lights towards the inside of the bend,
based on steering angle and road speed,

on tight bends and turns. Put simply, the
road ahead is illuminated the moment
you enter a bend. Speed-sensitive head -
light range control is also part of the
PDLS as is the adverse weather function.
LED main headlights with Porsche
Dynamic Light System Plus (PDLS +
).
Superior safet y meets sport y design in
the form of the LED main headlights with
PDLS +
which are available as optional
equipment. Each headlight housing
features four LED spots for the day time
running lights, and one LED light ring.
In addition to being efficient and long-
lasting, LED technology also creates

a light very similar to daylight which
helps to reduce driver fatigue.
One special feature of PDLS +
is the
dynamic main beam function. A camera
detects the lights of vehicles ahead as
well as those of oncoming traffic. Based
on the data from the camera, the dynamic
main beam function then adapts the
headlight range accordingly. This continu -
ous, stepless control means that you are
able to see the course of the road,
pedestrians and potential hazards earlier
without hindering other road users.
