oriented traction control improves
handling when accelerating on
different road surfaces. It also
prevents the rear of the car from
oversteering if a wheel loses
traction under full power. However,
the intervention threshold is
relatively high, which means that
it is rarely employed in normal
dry conditions.
A unique feature of PSM on the
911 GT3 models is that the control
interventions of both systems
are delayed and can be disabled
completely in two stages. This
enables greater driver involve-
ment, for example, when on the
racetrack. Stage 1 disables the
Stability Control (SC) via the 'SC
OFF' switch in the center console.
In 'SC OFF' mode, the system does
not intervene if the car goes off-
course in the lateral direction. In
addition to specific steering move-
ments, the vehicle can now also
be controlled with the throttle to
drive very dynamically around
curves. Traction Control (TC) is
still active in this mode.
Stage 2 disables Traction Control
as well via the separate 'SC+TC
OFF' switch. In this mode both
lateral dynamic control and the
traction control functions are
deactivated. The driver now has
full command of the vehicle.
In both stage 1 (SC OFF) and
stage 2 (SC + TC OFF), the lateral
dynamic control is not reactivated
again even when there is hard
braking within the ABS range. This
strategy enables motorsport-
derived dynamics for personalized
performance on the racetrack.
Compared to the 911 GT3, the
PSM in the new 911 GT3 RS is
set for even higher performance.

The anti-lock braking system inte-
grated in PSM (ABS 8.0) remains
active in all of these settings. ABS
ensures that the braking distance
is as short as possible for greater
safety.
