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.

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, fit ted as standard on
the new 911 Targa 4 models, combines
a high level of sport y 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 t ypical
Porsche st yle.

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.

Intelligent lightweight construction.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second, a
low vehicle weight primarily as a result of
the intelligent lightweight construction.
To achieve both goals, therefore, we used
very thin, but nevertheless extremely
rigid sheets of steel for the bodyshell.
In addition, aluminium was used exten -
sively in areas such as the underbody,
the front and rear ends, the doors, the
wings and the engine compartment
and luggage compartment lids, whilst
magnesium – a particularly lightweight
material – was selected for the front roof
elements of the new 9 11 Targa 4 models.

Porsche Active Suspension
Management (PASM).
PASM, the electronic damping control
system, is standard on the new
911 Targa 4S and available as an option
for the new 911 Targa 4. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension is
lowered by 10 mm. PASM has t wo modes
which can be selected using a separate
button on the centre console: ‘Normal’,
which is blend of performance and
comfort, and ‘Sport ’ where the setup
is much firmer.
Sensors record the body movements
that accompany powerful acceleration,
braking or uneven road surfaces, for
example. The PASM control unit evaluates
the driving conditions and modifies the
damping force on each of the wheels in
accordance with the selected mode.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.

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
option. This integrated system provides
simultaneous enhancement for the chassis,
Art: very good.
Sport: excellent.
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.
