Wheels.
On the new 911, the wheels have been
enlarged by one inch over the previous
model. Not only do the larger wheels
improve dynamic performance, they
also look more imposing.
The new 911 Carrera models are
equipped with 19-inch Carrera wheels as
standard. These are lightweight
alloys featuring a classic sport y design.
Tyre sizes are 235/40 ZR 19 and
285/35 ZR 19 at the front and rear
respectively.
The S models are equipped with light-
alloy 20 -inch Carrera S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to cope with the increased power output
of these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear.
The larger t yre size improves both ride
comfort and track performance. The

rolling resistance of the t yres
has been
reduced by up to 7 % to improve
fuel
economy, while t yre weight and dry brak -
ing distances have also been reduced. A selection of 20-inch wheels is available in
our range of options.
Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) is available
on request. This safet y system sends
warnings to the on-board computer’s
display screen in the event of low t yre
pressure or a gradual or sudden loss
of pressure. The individual pressures
in all four t yres can be displayed in the
instrument cluster.
Porsche Stability Management (PSM).
As standard, the new 911 models

are equipped with enhanced Porsche
Stabilit y Management (PSM), which
maintains stability even at the limits of
dynamic driving performance. Sensors
continuously monitor the direction,
speed, yaw velocity and lateral acceleration
of the car. Using this information, PSM is able to calculate the actual direction
of travel at any given moment. If the car
begins to oversteer or understeer, PSM
applies selective braking on individual
wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake differential
(ABD) and anti-slip regulation (ASR). When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving st yle.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels)
requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of
driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

Electric parking brake.
The new 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 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. In addition to the central airbag control
unit on the transmission tunnel, a pair

of impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated far sooner and
with considerably greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the new 911 models
are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact protec -
tion elements in the doors and t wo air -bags 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.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera
Cabriolet models have exemplary torsional
rigidit y and flexural strength. Body flexing
is minimal, even on the most poorly sur -
faced roads.
Increased protection is provided by an
automatically deploying roll-over protec -
tion system if the car were to overturn.
Two spring-loaded roll-over bars are
neatly incorporated behind the rear
seats. The roll-over sensor continuously
monitors the car’s pitch and roll, contact
with the road, as well as lateral and
longitudinal forces. If the car were to
overturn, the roll-over bars would be
deployed instantly.
