How to Understand the Difference Between 4-Wheel-Drive and All-Wheel-Drive
In many circles, people tend to lump 4-wheel-drive and all-wheel-drive into one definition, but even though the two definitions are similar, they accomplish their task in different ways. The 4-wheel-drive system uses a lowered gear ration system and a split differential to accomplish its mission. It is found in pickup trucks and larger off-road SUVs. It provides a rugged traction in off-road and difficult terrain conditions.
The all-wheel-drive system, on the other hand, is used in sedans, crossovers, and high-performance types of vehicles, primarily on paved road surfaces.
