Drive 51
The essential feature of all 911
all-wheel
drive models: enhanced Porsche Traction
Management (PTM).
Derived from the 911
Turbo, the
electronically controlled and fully variable
multi-plate clutch distributes drive force
between the permanently driven rear
axle and the front axle even faster and
more precisely than ever before.
The driving state of the vehicle is
continuously monitored so that it is
possible to respond to different driving
situations. Sensors are used to collect a
range of data, including the rotational
speed of all four wheels, the lateral and
longitudinal acceleration of the car and
thecurrent steering angle.
If, for example, the rear wheels threaten
to spin under acceleration, a greater
proportion of drive force is transmitted
to the front by a more powerful
engagement of the multi-plate clutch.
In this way, PTM, working in conjunction
with Porsche Stability Management
(PSM), always ensures the appropriate
distribution of force necessary for
excellent driving performance and
particularly well-balanced handling at
the limit.
Drizzle, snow, leaves, sun.
Perfect weather for some sports action.
