The Toyota Hybrid System (THS) combines gasoline and electric power to allow the gasoline engine to run only when it has to, shutting off at low speeds and stops, when the electric motor can exclusively power the car. The Prius maintains 49 mpg in the city and 51 mpg on the highway, making it the most fuel-efficient hybrid on the market.
