How does ford escape awd work?

The AWD in the Ford Escape helps prevent tire spin, especially on slippery roads. The system monitors the wheel speed sensors and if it detects that one of the tires is spinning faster (slipping), it will transfer the torque to the other tires until all four are spinning at the same rate. Normally the Escape is operating as a front-wheel drive vehicle, but when traction loss is detected by the computer, the fluid is redirected inside the differential by way of a series of solenoids. This reduces the power going to the slipping wheel and provides power to the rear wheels. The computer is able to direct the power to each tire individually to help maintain control during a skid.
