PTM (Porsche Traction Management)

As on the 997 Turbo, the intelligent all-wheel control system "Porsche Traction Management" (PTM) is used as standard on the new 911 Carrera 4. It actively controls drive torque distribution between the front and rear axles depending on the current driving situation and the driver's wishes, and has been adapted to suit the 911 Carrera 4.
