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.
4wd in most vehicles is selectable, by a lever, shifter, or button and is usually rear wheel drive until you select 4wd with the selecter which engages the front wheels. the transfer case divides the power evenly between the front and rear driveshafts.wd = four wheel drive. awd = all wheel drive. These two are the same thing. It is a system where all four wheels of the car are connected to the engine and is very good on vehicles used where you need more traction than usual.
