So it can be the description of a vehicle configuration OR the operational mode of the drivetrain. 4WD Four-Wheel Drive Four-wheeled vehicle with a drivetrain that allows all four wheels to receive power from the engine simultaneously which provides better control on various surfaces. Can be used to describe the configuration of the vehicle OR as the operational mode of the drivetrain. 4WD vehicles usually can turn 2wheels off to be in a 2WD mode. See also AWD.
