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.

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.

It also displays the navigation system
map, delivers various warnings, including
alerts from the Tyre Pressure Monitoring
(TPM) system, and tells you the current
front /rear axle torque distribution. You
can also use it to carry out individual
set tings.
Steering wheels.
In the 9 11 Targa 4, there is a point at
which all forces come together: the
steering wheel, where driver and machine
meet. This is why all steering wheels have
a high-grip steering wheel rim in smooth-
finish leather and offer outstanding
ergonomics. A full-size airbag is integrated
as standard.
Sports steering wheel.
The sports steering wheel is fit ted as
standard and adjusts up to 60 mm for
reach and up to 40 mm for height.
Multifunction steering wheel.
The optional multifunction steering
wheel has four function but tons and t wo
thumbwheels for convenient operation
of audio, telephone and navigation func
-
tions, the colour display and on-board
computer. On request, the steering wheel
is available in smooth -finish leather,
carbon or mahogany.
In conjunction with PDK, the steering
wheels are equipped with t wo ergonomic
gearshift switches enabling you to
change gear directly from the steering
wheel. With the optional Sport Chrono
Package, the steering wheel also features
a display above the airbag module to
inform you whether the SPORT, SPORT
PLUS and Launch Control functions have
been activated.
Steering wheel heating.
For increased comfort on cold days,
steering wheel heating is available as an
option for the sports steering wheel and
multifunction steering wheel.
SportDesign steering wheel.
In conjunction with PDK, the steering
wheel features t wo gearshift paddles.
These are made from a strong alloy and
are ergonomically located behind the left-
and right-hand steering wheel spokes.
Pull the right-hand paddle and PDK shifts
up. Pull the left-hand paddle and PDK
shifts down. When PDK has been com-
bined with the optional Sport Chrono
Package, the left- and right-hand spokes
additionally feature a display that tells
you whether the SPORT, SPORT PLUS
and Launch Control functions have
been activated.
As with the sports steering wheel, the
optional SportDesign steering wheel is
adjustable for both height and reach and,
thanks to its grip mouldings, it ’s in safe
hands – even on the sportiest of drives.
