DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the new multi-
hole injectors have been optimised for
torque, power output, fuel consumption,
emissions and ef ficient combustion.
With direct injection, the engine manage-
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and fuel economy. operation to the prevailing conditions.
This results in instant acceleration,
extremely smooth running and an
extraordinary level of tractive power,

but with a comparatively low level of
fuel consumption.
For faster heating of the catalytic converters
after a cold start and optimum torque in
the upper load range, up to three injection
pulses take place per combustion cycle.
DFI improves the internal cooling of

the combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression
ratio, which helps to deliver more output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the
Lambda sensors.

VarioCam Plus System.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake
camshafts and switching the lift of the
intake valves.
The system first dif ferentiates bet ween
driver inputs that typify normal,
everyday driving and those inputs
that demand maximum performance.
The electronic engine management
system then seamlessly adapts valve

PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. 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 but ton on
the centre console: ‘Normal’, which is a
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. In
the new 911, the number of sensors
has been increased for improved data
acquisition and more ef ficient control
interventions. The PASM control unit eval -
uates the driving conditions and modifies
the damping force on each of the wheels
in accordance with the selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer rating, thereby improving contact
bet ween the wheels and the road.

When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is selected
and the driver’s st yle becomes more
assertive, PASM automatically switches
to a harder rating. Damping firms up,
and driving stabilit y and road safet y are
increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The new PASM sports suspension is
available as an option for the 911 Coupé
models in conjunction with 20-inch wheels
and Porsche Torque Vectoring (PTV) or
Porsche Torque Vectoring Plus (PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti-roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler extends even further. These not only

further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even
better performance.

6061
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.

Climate control.
The new 911 models feature t wo -zone
automatic climate control as standard
with an enhanced ventilation effect and
separate temperature controls for the
driver and front passenger. The available
air conditioning modes are gentle,

normal and strong.
An active carbon filter traps particles,
pollen and odours and an automatic
air-recirculation function permanently
monitors air quality, reduces humidity
and switches from fresh to recirculated
air when required. A demister function keeps the windows
clear in cold weather. In warmer weather,
a solar sensor helps the climate control

to detect strong sunlight and automatically
compensate for the comfort of both the
driver and front passenger.
HomeLink®
(programmable garage door opener).
As an option, it is possible to have
a programmable garage door opener
integrated into the overhead console.
At the push of a but ton, it controls up
to three different garage doors, lighting
systems or alarm systems.
Many things have practical qualities.
Even more have a sporty function.
And some are just extremely convenient.

Additional comfort and convenience features.

door pulls, door storage compartments,
front foot wells and rear seats.
‘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 - of f timer
keeps the daytime 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 30 –240 km/ h
(18 –149 m p h )
speed range and is activat -
ed using a
button on the steering column

Exterior mirrors and rear-view mirror.
The most prominent new feature of the
electrically adjustable exterior mirrors is
their position. They are mounted directly
on the doors for improved aerodynamics.
Electrically folding exterior mirrors with
courtesy lighting on both sides of the
vehicle are available as an option.

Roof transport system.
Available as an option for the Coupé
models, the new roof transport system in
aluminium is aerodynamically efficient,
very light weight and easy to fit. A range
of at tachments is available, such as a
roof box, a bike carrier or a ski/snowboard
carrier. Maximum roof load is 75 kg.
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 wind -
screen wipers, is available as an option.Slide/tilt sunroof.
The optional electrically adjustable slide/
tilt sunroof for the Coupé models is a
completely new design. It opens out wards
so that it does not interfere with head -
room. Another advantage of the new
design is the much larger aperture for
increased driving pleasure under the
open sky. The newly developed t wo -position net-
t ype wind deflector protects against
draught and further reduces wind noise.
ParkAssist.
Park Assist is fit ted as standard in the
911 Cabriolet models and is available as
an option for the 911 Coupé models.

Featuring four inconspicuous sensors in
the rear end, the system audibly alerts
the driver to the presence of obstacles
detected behind the vehicle. An intermit -tent warning tone increases in rapidity

as the obstacle is approached.
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 screen, which
shows a graphical representation of
the vehicle from overhead.
Luggage compartment.
The luggage compartment volume
in the new 911 models is 135 litres.
The luggage compartment is fully
trimmed in scratch - resistant materials.

Environment
Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate
fuel consumption and exhaust emission
values in their respective category.
This is achieved, on the one hand, through
the use of fuel - ef ficient technologies such
as auto start /stop, thermal management,
electrical system recuperation, direct fuel
injection, VarioCam Plus and, in conjunction
with optional PDK, coasting mode.
On the other hand, newly developed
cataly tic converters provide ef ficient
emission control.
The stereo Lambda control circuitr y
controls and monitors each cylinder bank
separately. For each exhaust tract,
oxygen sensors regulate the composition of the exhaust gas, while another Lambda
sensor on each cylinder bank monitors
pollutant conversion in the respective

cataly tic converter.

Fuel economy and recycling.
Intelligent light weight construction has
been fundamental to the Porsche identit y
since 1948, for both technical and
ecological reasons. This forms the basis
for achieving low fuel consumption
values in conjunction with outstanding
performance.
On the technical side, we use a high
proportion of aluminium, magnesium,
plastics and super-high-strength sheet
steel. The materials used have been
selected for their ability to withstand
load, yet they are considerably lighter
than conventional steel.
On the ecological side, all materials used
are meticulously selected. All synthetic
components are easily recyclable and each
material is labelled to facilitate its separa -
tion for recycling. The reduction in the
number of plastic variants helps to ensure
more ef ficient recycling. Recycled plastics
are used where they meet our exacting
technical requirements.
In short, the new 911 is around 95 %
recyclable.
In addition, Porsche uses a high propor -
tion of environmentally friendly water-
based paints. For us, environmental
protection does not begin at the end of
a vehicle’s life. It starts at the planning
and development stage.

Fuel.
All Porsche models – including the new
911 – are designed to operate on fuels
with an ethanol content of up to 10 %,
e.g. ‘E10’. Ethanol has a positive impact
on the CO
2 balance since the plants
grown for the production of this biofuel
also absorb CO
2 from the atmosphere.
The release of hydrocarbons from the
fuel system has been minimised thanks
in no small part to the active carbon filter
and the multilayered material from which
the fuel tank is made. All fuel lines are
made from multilayered plastic, steel or
aluminium.
For fuel consumption and CO
2 emissions please refer to page 129.
