440 views

Hybrid cars make that distinct low-pitched noise due to their electric motors in operation. Primarily, this sound is generated when the vehicle is running at low speeds or when starting, as a safety feature to alert pedestrians of its presence, since electric and hybrid vehicles are much quieter than traditional gasoline-powered cars. This noise is a result of regulations requiring such vehicles to produce an audible sound for pedestrian safety.
