four-wheel drive
All-terrain transmission system
Four-wheel drive is a system that delivers engine power to all four wheels of a vehicle simultaneously, improving traction on rough terrain, snow, or mud.
Often abbreviated 4WD or 4x4.
The term also describes vehicles equipped with this system: We took the four-wheel drive up the mountain road.
Compare all-wheel drive, which operates continuously rather than being engaged manually.
