AWD is all the wheels having power at some time, 4WD is a switch to make all four wheels have power,I should say a switch,or lever,and maybe hubs that need turned to lock in.4WD vehicles will run in two wheel drive.They might drive on either front or back wheels until locked in. FWD is just front wheel drive only.
Diffen âº Science âº Physics âº Mechanics. All wheel drive or AWD means that the vehicle is designed to provide power to all four wheels at the same time, and in most cases cannot be switched to the two wheel drive (2WD) option.The distribution of power to the front-and hind-set of wheels differs from one system to another.4WD or four wheel drive (part time and full time) also means the vehicle has a drivetrain that allows all four wheels to receive torque from the engine simultaneously.he distribution of power to the front-and hind-set of wheels differs from one system to another. 4WD or four wheel drive (part time and full time) also means the vehicle has a drivetrain that allows all four wheels to receive torque from the engine simultaneously.
