Rear-wheel drive (RWD) typically places the engine in the front of the vehicle and the driven wheels are located at the rear, a configuration known as front-engine, rear-wheel drive layout (FR layout). The front mid-engine, rear mid-engine and rear engine layouts are also used.
The rear differential is an important car part which performs the function of directing the engine power at the wheels. This gear system is placed at the back of rear-drive cars. Whenever an automobile takes a turn, the wheels need to rotate at different speeds.
