What does front-wheel drive and rear-wheel drive mean in cars?

[GiaLynn]

Front-wheel drive in cars refers to a power distribution design where the engine drives only the front pair of wheels; rear-wheel drive means the engine's power is transmitted to the rear wheels via a driveshaft, propelling the vehicle forward. Rear-wheel drive is a more traditional form of drive, with early cars mostly being rear-wheel driven. In rear-wheel drive, the rear wheels act as the driving wheels responsible for propelling the entire vehicle, while the front wheels serve as the steering wheels for direction. Figuratively speaking, when moving forward, the rear wheels push the front wheels, driving the vehicle forward. Rear-wheel drive cars exhibit better acceleration performance and higher comfort levels. During vehicle start-up, acceleration, or climbing, the center of gravity shifts backward, increasing the grip of the rear wheels as driving wheels, which is beneficial for starting, accelerating, or climbing, providing better driving stability and comfort.
