Which statement correctly describes a Hybrid Vehicle?

• A. It blends a gasoline engine and a high-voltage electric motor to improve fuel economy
• B. The gasoline engine must always run for the vehicle to move
• C. It uses only electric power with no gasoline
• D. It is powered by hydrogen fuel cells only

Answer: (A)

A hybrid vehicle uses both a gasoline engine and a high-voltage electric motor with a battery, switching between or combining them to maximize fuel economy. This setup lets the car run on electric power at low speeds or during light acceleration, while the gasoline engine can supply extra power or recharge the battery as needed. Regenerative braking helps replenish the battery, so the system continually uses the most efficient power source for current conditions. That’s why the statement describing a blend of a gasoline engine and an electric motor to improve fuel economy is the best fit. The other ideas don’t apply to hybrids: the gasoline engine doesn’t have to run constantly for motion, since electric drive can move the car on its own in some situations; it isn’t powered exclusively by electric power with no gasoline, which would describe a pure electric vehicle; and it isn’t powered only by hydrogen fuel cells, which describes a hydrogen fuel cell vehicle rather than a conventional hybrid.
