RWD and AWD are two terms used in automobile wheel configuration, where RWD stands for Rear Wheel Drive, and AWD stands for All Wheel Drive. The number of wheels being driven by the engine is the major difference between these terms. Let us make reference to a four-wheel automobile. All the wheels are driven in an All-Wheel Drive (AWD), while only the two wheels at the rear are driven in a Rear Wheel Drive (RWD).
In AWD, all the forces on the automobile are equally distributed on the four wheels, which give it better balancing and more traction. The chance of slippage for AWD is minimal. In an RWD, on the other hand, the steering controls the front wheels while the rear wheels receive all the torque. It is more effective to steer an AWD than an RWD, as AWD steers better and easier than RWD. The front wheels of the RWD are being pushed, while the front wheels of the AWD also do the pulling together with the rear wheels.
