Is the BMW X3 AWD or 4WD?

Is the 2005 BMW X3 all-wheel drive or is it four-wheel drive? And what is the difference?

Hi Mike,

Though some people still think there's a clearly defined difference between the terms all-wheel drive (AWD) and four-wheel drive (4WD), the truth is that that line has been blurred through the years and the terms are now used interchangeably by most people, and even by the car makers.

Originally, 4WD vehicles were those defined as having selectable four-wheel drive, usually with locking differentials and even low-range transfer cases. In comparison, AWD cars generally had automated systems that manage where the engine's output is going.

The BMW X3 is the latter, but I'd advise you not to get to caught up on strict definitions of AWD vs. 4WD.
