In a hybrid vehicle, what is the role of the electric motor?

The electric motor in a hybrid vehicle plays a crucial role in both providing propulsion and assisting the gasoline engine. Hybrid vehicles are designed to take advantage of both electric and gasoline power to enhance efficiency and performance. The electric motor can operate independently to drive the vehicle at lower speeds, which is often more efficient than a gas engine. Additionally, during acceleration or under certain load conditions, the electric motor works in conjunction with the gasoline engine to provide extra power and improve overall performance while reducing fuel consumption and emissions.

In contrast to solely recharging the battery or replacing the engine, the electric motor's primary function encompasses active engagement in the vehicle's propulsion system. It does not operate independently for non-propulsion functions like air conditioning either, as those systems are typically powered by the engine or a separate electric system.
