AWD essentially works on its own. If you own a vehicle with AWD, all wheels will receive power at all times, no matter how fast or slow you're driving. The front and rear wheels will each receive the right amount of power along the way as the computerized system adapts to the driving conditions. In muddy or slippery conditions — or if you speed up — more torque will go to the rear wheels. While these basics apply to all AWD systems, different vehicle models will have different AWD features.
