Which components make up a vehicle's powertrain?

The powertrain of a vehicle is primarily responsible for generating power and delivering it to the wheels, enabling the vehicle to move. The components that constitute the powertrain include the engine, which is the heart of the system that converts fuel into mechanical energy; the transmission, which transmits this energy to the wheels while allowing the vehicle to change speed and torque effectively; the driveshaft, which transfers the power from the transmission to the differential; and the differential, which allows the wheels to rotate at different speeds, especially important when navigating turns.

Together, these components work cohesively to ensure that the vehicle can operate efficiently and effectively, making this combination the correct identification of the powertrain components. Other options provided consist of systems and components that, while essential for vehicle operation, do not directly relate to the production and transmission of power to the wheels.
