A hybrid electric vehicle uses which types of motors?

A hybrid electric vehicle integrates two distinct power sources: an internal combustion engine, typically running on gasoline, and an electric motor. The combination of these two types of motors enables the vehicle to optimize fuel efficiency and reduce emissions. The gasoline engine provides the necessary power for driving at higher speeds or for longer distances, while the electric motor is beneficial for low-speed driving and can also assist during acceleration.

This dual system allows for regenerative braking, where energy that would normally be lost is captured and used to recharge the vehicle’s batteries. This design not only enhances performance but also contributes to lowering the overall environmental impact compared to traditional vehicles that rely solely on gasoline engines.

In contrast, the other options include different motor combinations that do not align with the standard design of hybrid electric vehicles. For example, diesel engines or biodiesel motors are not typically found in hybrid designs, and the concept of "hybrid motors" is not recognized in this context. Therefore, the combination of gasoline and electric motors accurately represents the functional architecture of hybrid electric vehicles.
