XWD

It’s not just all-wheel drive. It’s the all-innovative Saab XWD, a cutting-edge cross-wheel drive technology — available on select Saab vehicles. The Saab cross-wheel drive system distributes driving torque to where it’s needed most. On the Saab Turbo X with rear limited slip differential (eLSD), electronic control not only distributes torque between the two axles, but also between the rear wheels.

Distribution

The torque transfer device (TTD) distributes torque between the front and rear axles. The Saab Turbo X’s eLSD allows variable torque transfer between the rear wheels.

Control

The electronic control unit (ECU) is the brains of XWD. ECU collects information continuously from Saab vehicle systems to sense driver intentions and changing vehicle state. It can distribute torque in fractions of a second, receiving updates form more than 20 sensors 100 times every second.

Results

These XWD components, can change the torque distribution continuously without waiting for wheel slip to occur. The result is better handling, improved stability and a sportier driving experience in all conditions. Select Saab models can be equipped with Saab XWD.
