It includes the engine, transmission, driveshaft, and other parts that transfer the engine’s power to the vehicle’s wheels, enabling it to move. The engine produces the power, while the transmission controls the flow of power, allowing the vehicle to change speeds. The power train is essential for the vehicle’s performance, and its efficiency affects things like speed, fuel economy, and handling.
