4WD (four-wheel drive) systems are often designed for serious off-road use, are typically selectable by the driver (you turn it on for rough terrain), and may include a low-range gearbox. AWD (all-wheel drive) systems are typically full-time, automatically engaged systems optimized for improved traction on various road surfaces (e.g., wet, snowy), not necessarily for rock crawling.

When used as a noun to mean the vehicle, it's 'a four-wheel drive' (e.g., 'He owns a four-wheel drive'). When used as a compound adjective before a noun, use hyphens: 'a four-wheel-drive vehicle' or 'four-wheel-drive capability'.
