Which vehicle uses both battery-powered electric and gasoline propulsion?

• A. Battery Electric Vehicles
• B. Hybrid Electric Vehicles
• C. Conventional Vehicles
• D. Alternative Vehicles

Answer: (B)

Hybrid electric vehicles combine a battery-powered electric motor with a gasoline engine to propel the vehicle. The system can use electric power for light, low-speed driving and the gasoline engine for higher speeds or longer trips, often switching between or blending both sources as needed. The battery is charged through the engine's activity and by regenerative braking, so energy is recovered during braking. Battery electric vehicles rely only on electricity from batteries and have no gasoline engine, while conventional vehicles run on gasoline alone. The term alternative vehicles is broad and doesn’t specify the dual propulsion setup. So, the vehicle that uses both battery-powered electric and gasoline propulsion is a hybrid electric vehicle.
