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.

Sport Button
Standard on all new 911 Turbo models,
the Sport but ton enables you to select
a suspension setup to emphasize either
comfort or sport y performance. At
the push of a but ton, the electronic
engine management system switches
the engine mapping to offer an even
sharper response. In conjunction with
the Sport Chrono Package (standard
in the 911 Turbo S and the new
911 Turbo S Cabriolet), the overboost
function is then active and the dynamic
engine mounts become much firmer.
In Sport mode, PDK ensures that
upshifts take place at higher engine
speeds and downshifts happen sooner.
Coasting mode and the Auto Start
Stop function are deactivated.
Sport Chrono Package Including
Dynamic Engine Mounts
The Sport Chrono Package including
dynamic engine mounts is standard in
the 911 Turbo S models and available
as an option for the new 911 Turbo. This
integrated system provides simultaneous
enhancement for the chassis,
including rear-axle steering, engine,
transmission, and aerodynamics.
The main features include a digital
and analog stopwatch mounted on the
dashboard, a performance display in the
Porsche Communication Management
(PCM) system, the Sport Plus but ton,
and the overboost function.
Activate Sport Plus mode and here’s what
happens: Porsche Active Suspension
Management (PASM), the electronic
suspension management, becomes more responsive. PASM and Porsche Dynamic
Chassis Control (PDCC)—standard in the
new 911 Turbo S—switch to Sport Plus
mode for a firmer suspension set ting,
more direct steering while cornering, and
increased roll stabilization. The rear-axle
steering also reacts more directly—for
even more agile steering. As part of
Porsche Active Aerodynamics (PA A),
the automatic adjustment of the front
and rear spoilers is also impacted in
the performance setting in Sport Plus
mode. So you can make full use of the
performance potential of your 911 Turbo.
In Sport Plus mode, the trigger threshold
for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit
acceleration. For maximum dexterit y, PSM
can be set to standby while the car
i

s
still in Sport Plus mode. Although, for
safet y, it ’s still there in the background. With the Sport or Sport Plus but ton
active, under full acceleration, the
maximum boost pressure in the
lower and medium speed ranges
is now temporarily increased by
approximately
2 psi: the overboost.
Engine torque is also boosted
by 37 lb.-ft. for a short time—to
524 lb.-ft. in the 911 Turbo and the
911 Turbo Cabriolet. In the 911 Turbo S
models, it goes up to 553 lb.-ft.
The Sport Chrono Package has t wo
additional functions. The first is
Launch Control, which helps achieve
optimal acceleration from a standing
start. The second function is the
motorsport-derived gearshift strategy.
Using this, PDK optimizes shift
points to the shortest possible shift
times for maximum acceleration.
