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.
