Here's why:
* Driving wheels: They "drive" the vehicle forward or backward by converting the engine's power into motion.
* Powered wheels: They are the wheels that are directly connected to the engine's power source (usually the transmission).
In most cars, the rear wheels are the driving wheels, making them rear-wheel drive (RWD). Some cars have front wheels as the driving wheels, making them front-wheel drive (FWD). There are also all-wheel drive (AWD) vehicles that use both the front and rear wheels to drive the vehicle.
