Transmission.
1 Power transmission in 1st gear
Porsche Doppelkupplung (PDK)
All of the new 911 Turbo models
feature the enhanced PDK transmission
with manual and automatic modes.
Porsche engineers have yet again
increased the speed and smoothness
of gear shifts. For the driver, this
means even faster shifting through
the gears without interrupting the flow of power. Acceleration
is exceptional, fuel consumption
is optimized, and performance is
delivered at a high level of comfort.
PDK has seven gears at its disposal.
Gears 1 through 6 have a sport ratio
and top speed is reached in 6th gear.
The 7th gear has a long ratio and
helps to reduce fuel consumption
by keeping engine revs low.
PDK is essentially t wo transmissions in
one. This double-clutch arrangement
provides an alternating, non-positive
connection between the two 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, one clutch simply opens and the other
closes at the same time, enabling shifts
to take place within milliseconds.
Depending on the gearshift program
(Sport button activated or deactivated),
the shift of gears is optimized for
comfort or for sporty driving.With the optional Sport Chrono Package
(standard in the 911 Turbo S models),
PDK is enhanced by the Launch
Control and motorsport-derived
gearshift strategy functions.

Coasting
The coasting function enables you
to save even more fuel when the
situation allows. In coast mode,
the engine is decoupled from the
transmission to prevent deceleration
caused by engine braking. Optimal use
is made of the vehicle’s momentum,
allowing the 911 Turbo to seamlessly
coast at certain times while
consuming significantly less fuel.
It works like this: Say, for example,
you want to slow down from 65 mph to
55 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 the coast function helps
reduce fuel consumption is when you’re
driving downhill. If the gradient is gentle
enough for you to maintain a constant
speed, the transmission decouples
the drive power to save fuel. Yet 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.

1 Porsche Ceramic Composite Brake (PCCB)
Porsche Ceramic Composite Brakes
(PCCB)
How exactly does Porsche take its
motorsport experience and transfer
it from the racetrack to the road? The
Porsche Ceramic Composite Brakes
(PCCB) are a clear example. Standard
equipment in the 911 Turbo S models
and available as an option for the
911 Turbo models, PCCB has already
had to cope with the harsh requirements
of motor racing and is fit ted in race
cars that compete in demanding events
such as the Porsche Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs have a diameter of 410 mm at the front and 390 mm at the back—for even
more formidable braking performance.
The use of 6-piston, aluminum monobloc
fixed calipers on the front axle and
4-piston, aluminum monobloc units
at the rear—all finished in yellow—
ensures extremely high brake forces
that remain exceptionally consistent.
PCCB enables shorter braking distances
in even the toughest road and track
conditions. Excellent fade resistance
guarantees greater balance when
slowing from highway speeds.
The key advantage of PCCB is the
extremely low weight of the ceramic
brake discs. Approximately 50 percent lighter than standard discs of similar
design and size, they enhance
performance and fuel economy.
Because this represents a major
reduction in unsprung and rotating
masses, it yields many results: bet ter
roadholding and increased comfort,
particularly on uneven roads, as well as
greater agility and improved handling.

Body
The innovative bodyshell of the new
911 Turbo models fulfills t wo structural
design requirements: first, excellent
driving dynamics due to the body’s
extremely high rigidit y. Second, a
savings in vehicle weight, primarily due
to its intelligent lightweight construction.
To meet the second requirement, we
employed state-of-the-art techniques
for combining various materials in order
to utilize specific material properties
exactly where they are needed.
Take the bodyshell, for example. It uses
very thin—but extremely rigid—sheets
of steel. Aluminum and magnesium
were utilized extensively in areas
including the roof, underbody, doors,
engine compartment, and luggage compartment lids. Magnesium, which
is a particularly lightweight material,
was also selected for the cockpit
and center console support beam.
Reducing the overall weight—i.e.,
improving the power-to-weight ratio—
translates directly into the aim of
increasing performance, whether
that ’s measured by the acceleration,
steering, or braking. And it ’s measurable
another way, too: at the fuel pump.
Reduced fuel consumption.
For the driver, reducing the weight
of the 911 Turbo results in a high
level of comfort as well. Vibration-
damping characteristics are
excellent and, compared to the
previous model, torsional stiffness
has increased up to 25 percent to
create even sportier handling.
Airbags and the Po
rsche Side Impact
Protection (POSIP) System
The airbag technology in the new 911 Turbo
models provides full-size driver and front-
passenger airbags, which are inflated in t wo
stages depending on the severit y and t ype
of accident. In less serious accidents, the
airbags are only partially inflated to help
minimize discomfort to the occupants.
Another standard feature is the Porsche
Side Impact Protection (POSIP) system.
This system comprises side impact
protection elements in the doors and t wo
airbags on each side, an integral thorax
airbag located in each seat side bolster,
and a head airbag contained in each of
the door panels. Knee airbags are also
standard on all 911 Turbo models.
Rollover Protection in the
Cabriolet Models
Despite their light weight, the 911 Turbo
Cabriolet models have exemplary
torsional rigidit y and flexural strength.
Body flexing is minimal, especially when
compared with driving most other open-
top sports cars on uneven road surfaces.
In the event of a 911 Turbo Cabriolet
model rolling over, additional protection
is provided by a supplemental safet y
roll bar protection system that deploys
automatically. The two spring-loaded
rollover bars are located behind
the back seats. The rollover sensor
continuously monitors the car’s pitch
and roll, lateral and longitudinal
acceleration, and contact with the road.
In an emergency, it deploys the rollover
bars within a fraction of a second.

6768 Responsibility | Environment
Porsche has increased efficiency in all
of its current series while at the same
time increasing performance. This is
achieved by an efficient drive, thanks
to Direct Fuel Injection (DFI), Porsche
Doppelkupplung (PDK), Variable Turbine
Geometry (V TG) and VarioCam Plus,
intelligent lightweight construction, active
aerodynamics, and low rolling resistance. A high level of environmental
responsibilit y is ensured not least
by Porsche’s own environmental
management teams in Weissach. They
ensure that all developments take
account of environmental compatibility.
The objective is to achieve pure
performance, but not at the expense
of the environment. This also applies
to the new 911 Turbo models.
All automotive manufacturers look
to the future. After all, the life-span
of an automobile from inception to
the end of its functional life can span
decades or even longer. So what
the world needs in 15 to 20 years,
Porsche engineers must address now.
Our focus is always on this: ultimate
performance with ultimate efficiency.
What we find when we go our own way:

solutions.
Environment.
Exhaust Emissions Control
At Porsche, our cars have long
demonstrated that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emissions
values in their respective category. The new 911 Turbo is no exception. It
uses technologies such as Auto Start
Stop, thermal management, electrical
system recuperation, Direct Fuel Injection
(DFI), VarioCam Plus, and coasting
to help optimize fuel efficiency.And the cataly tic converters provide
efficient emissions control.
The stereo lambda sensor 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 catalytic converter.

6970 Responsibility | Environment
Recycling
For both technical and ecological
reasons, intelligent lightweight
construction has been fundamental to
Porsche since our first car in 1948.
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 aluminum, 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 labeled to facilitate its
separation for recycling. The reduction
in the number of plastic variants helps to
ensure more efficient recycling. Recycled
plastics are used where they meet our
exacting technical requirements.
In short, the new 911 Turbo models are
approximately 95 percent recyclable.
In addition, Porsche uses a high
proportion 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. having the same fuel economy of 17 mpg
in the cit y and 24 mpg on the highway.
Noise
The 911 Turbo models and the new
911 Turbo S comply with all current
noise regulations—without resorting
to engine encapsulation. To achieve
this, we’ve eliminated noise at the
source: Engine components are
more rigid, moving parts lighter,
and tolerances reduced to a
minimum. High-efficiency silencers
and resonators in the intake system
help to reduce noise even further.
Fuel
All Porsche models are designed to
operate on fuels with an ethanol content
of up to 10 percent. 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 minimized, 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 aluminum.
The new 911 Turbo models have
maximized the fuel-saving technologies,
which results in all the 911 Turbo models
