Car’s All-Wheel-Drive AWD System Working Principle

via

AWD is a term used in vehicles that have the ability to transfer power to all four wheels. The transfer of power is often computer controlled, and features a central clutch that allows for a difference between the speed of the front and rear wheels, which suits it best for on-road use. AWD systems also differ from 4WD / 4×4 systems because there is no LO speed transfer case. source/
