The development of the automotive world is very fast progress. As with driving wheel technology used. For a car that can reach all fields, we recognize four-wheel drive system (four-wheel drive/4WD). Such as whether the system work?

Basically, the Four-Wheel Drive (4WD) only distribute power to all wheels when necessary. Because, when in normal condition, the vehicle also can move only with the help of two wheels (2WD) only. This is very possible to be done, owing to the transfer device case. The device is assigned stalemate / gardan integrate front and back.

One thing that sets All-Wheel Drive (AWD) with 4WD, that is, when equipped with 4WD low-range gear to run off-road terrain such as mud wallow, steep hills or steep ravine. All-Wheel Drive (AWD) is not equipped with it. Indeed, when we see the name given by car manufacturers, we will be confused by the variety name.
