What drives the car forward in a rear-wheel-drive system?

In a rear-wheel-drive system, the car is propelled forward primarily by the rear wheels. This design means that the engine's power is transmitted to the rear wheels through the drive shaft. When the engine powers the drive shaft, it rotates and sends that rotational force (torque) to the rear differential. The differential then distributes that power to the rear wheels, causing them to rotate and ultimately push the car forward.

Having the rear wheels drive the vehicle can enhance traction, especially during acceleration, since the weight of the car shifts backward when it accelerates, increasing the downward force on the rear tires. This can provide better grip and control compared to front-wheel-drive systems in certain situations, such as racing or when driving on slippery surfaces.
