A part-time system that powers all four wheels for improved traction during adverse road conditions and off-road use. Four-wheel drive systems differ from all-wheel drive (AWD) systems in two ways: they can be disengaged when not in use, and they are not suitable for use on dry pavement.
A common term is also 4WD.
