Porsche Torque Vectoring
(PTV Plus)
Functional Description
Despite the advantages of PTV, it is still the
driver’s responsibility to adapt his/her driving style
and maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PTV.
Risk of accidents due to inappropriate speed
cannot be reduced by PTV.
PTV Plus consists of a control system that
performs braking interventions based on driving
dynamics to achieve variable drive torque
distribution on the rear axle and of an
electronically controlled rear differential lock.
PTV Plus improves steering response and
precision through gentle braking interventions on
the inside rear wheel. This braking action cannot
be felt by the driver. The vehicle follows the
steering angle of the front wheels more precisely.
Understeer is largely prevented in the limit range.
This increases the lateral acceleration potential
and higher cornering speeds are possible.
The electronically controlled rear differential lock
continuously monitors the driving condition of the
vehicle and distributes the drive torque to the rear
axle as required.
