Rear-wheel drive (or RWD for short) is the most common Internal combustion engine/
transmission layout used in
automobiles. RWD typically places the engine in the front of the vehicle, but the
front mid-engine,
rear mid-engine and
rear engine layouts are also used. Rear-wheel drive is used almost universally for driving
motorcycles, whether by
driveshaft,
chain, or
belt. The vast majority of rear wheel drive vehicles use a
longitudinally-mounted engine in the front of the vehicle, driving the rear wheels via a
driveshaft linked via a
differential between the rear axles. Some
FR layout vehicles place the transmission at the rear, though most attach it to the engine at the front. Rear wheel drive has fallen out of favor in passenger cars since the late
1980s, due in part to higher manufacturing costs, and that
front wheel drive is safer for a driver of average ability<ref name="family">

Drive However, some automobile brands, including
Lincoln,
Mercedes-Benz,
BMW,
Lexus, and
Porsche continue to use rear wheel drive platforms. Rear wheel drive (or all-wheel drive) is still the preferred choice for
high performance automobiles, due to the fact that very powerful front wheel drive cars tend to
understeer.<ref name="forza"> The general limit of controllable power for a front wheel drive car is generally placed between 230 and 300 horsepower.
