Thermal Management
The thermal management system
regulates the temperature in the engine
and transmission through the intelligent
manipulation of heat flow. It allows the
engine and transmission to reach their
optimal operating temperatures sooner.
The result? Combustion efficiency and
lubrication performance are improved,
and fuel consumption is reduced.
Auto Start Stop Function
The Auto Start Stop function is standard
in the new 911 Turbo models. When
the speed falls below 4 mph and the
911 Turbo is decelerating normally, the
engine switches off. For example, as you
are slowing while approaching a red light.
Audio and communication systems
remain switched on. The climate
control continues to maintain your
selected temperature. The engine
starts again when you release the
brake or move the steering wheel.
The Auto Start Stop function may remain
inactive under particular circumstances,
for example if the bat tery charge is
low, when the Sport but ton is selected,
or when there are extreme outside
temperatures. It is also possible to
deactivate the function manually using a
separate button on the center console.
Electrical System Recuperation
Another fuel-saving innovation that’s
standard on the new 911 Turbo models
is electrical system recuperation
technology. It captures the energy
created during events such as braking.
The vehicle bat tery is recharged by
the alternator, predominantly under
braking. Under acceleration, on the
other hand, the power draw of the
alternator is limited to increase the
engine output available for driving.
The electrical systems are supplied
by the electrical energy stored
during the recharging process.

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
