A 4x4 (you say “four by four”) is a car or truck that can drive with power going to all four wheels. In everyday talk it is the vehicle itself — the thing you see in the car park — not only the hidden system inside.

How the name grew is a bit mixed, and that is the truth. It can point to four-wheel drive, to having four wheels, and sometimes to an older kind of gearbox with four speeds. The little x stands in for “by,” like a multiply sign, so people say “four by four.” You will also hear 4WD; that is usually the system. 4x4 is more often the whole vehicle.
