TORQUE SPECIFICATIONS

The All-Wheel Drive (AWD) system consists of the following

  1. Power Transfer Unit (PTU)
  2. Rear driveshaft
  3. 4X4 control module
  4. Rear axle with coupling device

The PTU is a mechanical device attached to the transaxle. It supplies torque to the rear axle through the rear driveshaft. The 4X4 control module is an electronic device which controls the rear axle coupling to apply the torque generated from the PTU to the rear wheels when required.
