AWD, also called 4x4, is a similar term to 4WD, but there are some key differences. AWD vehicles typically have a more advanced and sophisticated drivetrain system than 4WD vehicles. This allows AWD vehicles to distribute power to the wheels more evenly, which can provide better traction in slippery conditions. AWD vehicles also typically have a higher fuel efficiency than 4WD vehicles.
XT is an abbreviation for "Xtra Traction" and is used by some automakers to describe vehicles with either 4WD or AWD.
