Porsche Doppelkupplung (PDK).
Available as an option for the new 911
models is 7-speed PDK, featuring manual
and automatic modes. This double - clutch
transmission has been further refined and
enables extremely fast gear changes with
no interruption in the flow of power, which vastly improves acceleration at the
same time as reducing fuel consumption.
In total, PDK has seven gears at its disposal.
Gears 1 to 6 have a sports ratio and top
speed is reached in 6th gear. 7th gear has
a long ratio and helps to reduce fuel

consumption by keeping engine revs low.
Porsche Doppelkupplung (PDK)
PDK is essentially t wo gearboxes in one
and thus requires t wo clutches. This
double-clutch arrangement provides an
alternating, non-positive connection
bet ween the t wo half gearboxes and the
engine by means of t wo separate input
shafts.The flow of power from the engine is
transmit ted through one half gearbox and
one clutch at a time, while the next gear
is preselected in the second half gearbox.
During a gear change, therefore, one
clutch simply opens and the other closes
at the same time, enabling gear changes
to take place within milliseconds.
Temperament | Transmission
The effect is instant. Driving feels even
sportier and more dynamic, and agility
is increased. Depending on the gearshift
programme (SPORT button activated
or deactivated), the gear change is opti -
mised for comfort or for sport y driving.With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport- derived gearshif t strategy’
functions (p. 50). 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 100 km/ h (62 mph) to 80 km/ h
(49 mph) in anticipation of the change of
speed limit ahead. As soon as you release
the accelerator pedal, PDK deselects
the current gear automatically 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 appropriate 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.
In short, driving in coasting mode makes
a real impact on fuel consumption without
any need for compromise on comfort or
sporty performance.
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
deceleration caused by engine braking.

Power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the new electromechanical power steering.
Statistics show that a car drives in a
straight line 90
% of the time. Unlike
conventional hydraulic pumps, the electric
motor 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 at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the speed -sensitive
power-steering system, is available
as an option for the 911 Carrera models.
At high speeds, the steering is as firm
as you would expect and responds with
extreme precision while steering comfort
remains as high. At low speeds, the
steering ratio of Power steering Plus
adjusts for much easier manoeuvring
and parking.
SPORT button.
Fit ted as standard, the new SPORT
but ton enables you to select a suspension
setup where the emphasis is on either
comfort or sport y performance. At the
push of a button, 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 automati
-
cally 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, engine and transmission.
Every day can be sports day.

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 for a brief period 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).
The 911 Carrera and 911 Carrera S 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 the seat backrests, 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.
