Final answer:
Hybrid vehicles (HVs) are powered by both a battery and a gasoline or diesel engine. This combination allows hybrid vehicles to be more fuel-efficient and produce fewer emissions compared to traditional vehicles.
Step-by-step explanation:
True. Hybrid vehicles (HVs) are powered by both a battery and a gasoline or diesel engine. The battery provides power for the electric motor, while the gasoline or diesel engine provides power for the internal combustion engine. This combination allows hybrid vehicles to be more fuel-efficient and produce fewer emissions compared to traditional vehicles.
