Four-wheel drive, 4WD, 4×4, Quattro or AWD is a four-wheeled vehicle with a drive-train that allows all four wheels to receive torque from the engine at the same time. Full-time AWD is appropriate for improving road handling. All-wheel drive cars require more maintenance and fuel than an ordinary car.
