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 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.

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.

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.

Porsche Ceramic Composite Brake
(PCCB).
The optional Porsche Ceramic Composite
Brake (PCCB) has a proven track record
from the world of motorsport. The cross-
drilled ceramic brake discs have a diame -
ter of 350 mm front and rear for even
more formidable braking performance.
The use of six-piston aluminium monobloc
brake calipers on the front axle and
four-piston aluminium monobloc brake
calipers at the rear – all finished in

yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent. PCCB enables shorter braking
distances in even the toughest road and
race conditions. The key advantage of PCCB is the
extremely low weight of the ceramic brake
discs, which are approximately 50
%
lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this

represents a major reduction in unsprung
and rotating masses. The consequence of
this is bet ter road holding and increased
comfort, particularly on uneven roads.
Circuit racing will require extra main -
tenance to be carried out in addition to
the routine maintenance.
Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away. With the hill-hold function, you can pull
away without ever rolling back. The

system automatically detects when the
vehicle has come to a halt on an uphill
gradient requiring intervention. PSM then
maintains the brake pressure at all four
wheels to prevent the vehicle from
moving in the opposite direction.
Airbags.
The new 911 Targa 4 models offer
advanced airbag technology in the form
of full-size driver and front passenger
airbags, which are inflated in t wo stages,
depending on the severit y and t ype of
accident (e. g. frontal or offset frontal). In
less serious accidents, the airbags are
only partially inflated, thereby minimising
discomfort to the occupants.
Porsche Side Impact Protection System
(POSIP).
The new 9 11 Targa 4 models are equipped
as standard with the Porsche Side Impact
Protection System (POSIP). It comprises
side impact protection elements in the
doors and t wo airbags on each side. An
integral thorax airbag is located in each

seat side bolster, while the door panels
each contain an upwards-inflating head
airbag. Each thorax airbag has a volume
of 10 litres and each head airbag 15 litres,
ensuring excellent protection in the event
of a side impact.
Roll-over protection.
The 911 Targa 4 models have exemplary
torsional rigidit y and flexural strength.
Increased protection is provided by the
steel roll-over protection system located
under the aluminium panel of the Targa
roll bar.

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,
in order to illuminate more of the road

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.

‘Welcome Home’ lighting.
For convenience, particularly at night,
the ‘Welcome Home’ lighting function
automatically switches on the LED day-
time running lights for a defined period
whenever the vehicle is opened or
closed using the key remote.
A customisable delayed switch- off timer
keeps the day time running lights, the
taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Cruise control.
This automatic speed control function is
available as an option. For greater driver
comfort on long stretches of road, cruise
control operates in the 18–149 mph
speed range and is activated using a
button on the steering column control stalk.
Exterior mirrors and rear-view mirror.
Electrically adjustable exterior mirrors
are fitted as standard. Electrically folding
exterior mirrors with courtesy lighting
on both sides of the vehicle are available as an option. By illuminating the area in
front of the doors, they make it easier to
find your way in the dark. An auto -dimming
function for the rear-view mirror and
exterior mirrors, with an integrated rain
sensor for the windscreen wipers, is
available as an option. The SportDesign
exterior mirrors featuring a V-shaped
mirror base are also available as an
option.
ParkAssist.
Park Assist for the rear is fit ted as
standard. Featuring four inconspicuous
sensors fit ted at the rear, the system
audibly alerts the driver to the presence
of obstacles. An intermittent warning
tone increases in rapidity as the obstacle
is approached.
ParkAssist (front and rear).
An enhanced version of Park Assist,
with four sensors in the front end, is
available as an option. The audible alert
is supplemented by a visual warning in
the central display, which shows a
graphical representation of the vehicle

from overhead.
Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your pocket.
As soon as you grab the door handle or
approach the luggage compartment, the
door or luggage compartment lid unlocks.
The engine can then be started and
switched off using the electronic ignition
switch.
Anti-theft protection.
The new 9 11 Targa 4 models are equipped
as standard with an immobiliser with
in-key transponder and an alarm system
with radar-based interior surveillance.
The system secures the doors, luggage
compartment, passenger compartment
and ignition.
Adaptive cruise control including
Porsche Active Safe (PAS).
Also available as an option is the
enhanced version of cruise control, which
regulates the speed of your vehicle in line
with the speed of the vehicle in front. A
radar sensor scans the road ahead up to
a distance of 200 m.
Sense of style | Comfort
Imagine you’ve selected a cruising speed
but have begun to gain on the vehicle in
front because it is driving more slowly –
this is detected by the radar sensor. The
system now reduces the speed of your
vehicle at a maximum rate of 3.5 m/sec²
by restricting throt tle or by applying the
brakes as appropriate to the prevailing
situation until your chosen distance from
the vehicle in front is maintained.
Your vehicle now follows the vehicle
ahead at a reduced speed. If the vehicle
ahead slows further, adaptive cruise
control will decelerate your vehicle
accordingly – even down to a halt. As
soon as the road ahead clears, your
vehicle will accelerate back up to the
cruising speed originally set.
Porsche Active Safe (PAS) issues an audi-
ble and a visual warning if the system
detects that your vehicle is approaching
the vehicle in front too quickly. This is
accompanied by a brief jolt of the brakes
and, where necessary, the initiation of
targeted braking. During this process,
any braking by the driver is boosted to achieve the maximum braking force that
the system is able to provide.
Luggage compartment.
The luggage compartment volume in the
new 911 Targa 4 models is 125 litres.
The luggage compartment is fully
trimmed in scratch-resistant materials.
