Driving and Driving Safety
Despite the advantages of transmission and
chassis control systems, it is still the driver’s
responsibility to adapt his 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.
These systems cannot reduce the risk of
accidents due to inappropriate speed.
f
Adapt your driving style, maneuvers and speed
to the road and weather conditions, as well as
the traffic situation.
Porsche Traction Management
(PTM)
Porsche Traction Management is an active
allwheel control system designed to influence
longitudinal and lateral dynamics. It is closely
linked with the Porsche Stability Management
(PSM) system.
The permanently driven rear axle enhances the
vehicle’s sporty features. Drive power is
distributed fully variably to the front axle,
depending on the driving situation.
In conjunction with PSM, the PTM system ensures
perfect distribution of power among all four
wheels in every driving situation. This improves
traction and driving stability and ensures the same
high level of agility and dynamic response.
In spite of the advantages of PTM and four-wheel
drive, it is still the driver’s responsibility to adapt
his 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 PTM or four-wheel drive.
Risk of accidents due to inappropriate speed
cannot be reduced by PTM or four-wheel drive.
Advantages of PTM
– Clearly perceptible improvement in traction,
driving stability and steering ability of the
vehicle.
– Vehicle is more manageable when driven at its
performance limits.
– Improved straight-ahead tracking and greater
stability.
– More sporty vehicle setup while making full use
of all the advantages of four-wheel drive.
– ASR, ABD and PTV Plus further enhance
traction for all wheels.
