The 911 | Chassis
Launch Control is operated via the
‘Sport Plus’ button with the ‘D’ or
‘M’ drive position selected. Whilst
the driver depresses the brake
pedal with the left foot, the right
foot depresses the accelerator
pedal to the floor. With the accel-
erator in the kickdown position,
the system detects the driver’s
request for Launch Mode and revs
the engine to an optimum speed
of approximately 6,500 rpm.
Engine torque increases and
the clutch closes slightly. The
message ‘Launch Control active’
appears on the instrument cluster
display. The driver now quickly
releases the brake – and prepares
for maximum acceleration.
The second function is the ‘motor-
sport-derived gearshift strategy’.
Using this, Porsche Doppel-
kupplung (PDK) is geared up for
the shortest possible shift times
and optimum shift points for
maximum acceleration – ideal
for the racetrack.
A key component of Sport
Chrono Package Plus is the
timer mounted on the dashboard.
Porsche Communication
Management (PCM, p. 100) has a
special performance display to
view, store and evaluate lap times
or other driving times. It shows
the total driving time, lap distance,
lap number and the lap times
recorded so far. You can view
the current fastest lap and the
remaining range until empty.
Travelled distances can be record-
ed and benchmark times defined.
The personal memory function of
the Sport Chrono Package Plus
can also be used to store person-
alised settings for a range of
systems, including the orientation
lighting or air conditioning.
