What role does the electric motor play in a traditional full hybrid vehicle?

In a traditional full hybrid vehicle, the electric motor plays a vital role in supporting the gasoline engine to enhance efficiency and performance. Specifically, the electric motor assists the gasoline engine during acceleration and helps generate additional power when needed, such as during heavy load conditions or when quick acceleration is necessary. This assistance allows the vehicle to operate more efficiently, reducing fuel consumption and lowering emissions compared to a conventional gasoline engine alone.

The electric motor can also allow the vehicle to operate in electric mode at low speeds, which contributes to reduced engine load and improved fuel economy. However, it does not function independently to power the vehicle at all times, nor does it completely replace the gasoline engine; instead, both systems work in concert to optimize performance and efficiency. Additionally, while the electric motor does support various vehicle systems, it does not serve solely to power accessories.
