what is a 4x4 truck

A 4x4 truck or car, also known as four-wheel drive (4WD) or 4-by-4, is a system in which a vehicles engine powers all four wheels evenly. This means that all four wheels receive power from the engine, which can provide better traction and handling in off-road or slippery conditions. In contrast, a 4x2 or two-wheel drive (2WD) vehicle only powers two wheels, usually the rear wheels, which can limit its ability to handle rough terrain or poor weather conditions.
