Saab XWD will be used in new Saab Turbo X and 9-3 Aero XWD vehicles. XWD strands for Cross-Wheel-Drive and is technically called Haldex version 4.0. The main components of the new Haldex system are the Power Take-Off Unit (PTU), Limited Slip Coupling (LSC) and eLSD (Electronic Limited Slip Differential). I will take some point what i think it is intersting. also compare with Subaru which you do you like? I got a old news, now in Vancouver SAAB only have one dealers? is that true? someone could tell me?
This picture shows the LSC unit on the left side. eLSD on the right side is the eLSD. Hydraulic lines can be seen running between them.
for this picture, The eLSD sits between the rear axles and the LSC is mated to the driveshaft. The electronic control unit can be seen as a rectangle mounted on the nearside of the LSC.
The above picture shows the XWD driveline. At the forefront of the picture is the eLSD coupled to the LSC unit. The PTU can be see at the opposing end of the driveshaft.
