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.
All-wheel drive is running all the time, varying the amount of power to each wheel. Traditional four-wheel drive systems in many vehicles are classified as part-time systems, which means the vehicle operates in rear-wheel drive until four-wheel drive is selected by the driver.
