Hybrid cars do better in the city because they're using their electric motor more than they're using the gasoline engine. Think about it. The gasoline engine shut off at a complete stop. Many hybrid vehicles (especially those from Toyota) will accelerate from a complete stop on the electric motor and then the gasoline engine starts once it reaches a certain speed or sooner under heavy throttle. Also, many will use only the electric motor at low speeds.The accelerating part probably is most significant in the high MPG because a conventional gasoline vehicle uses the most fuel when accelerating until it gets up to speed. Also, in city driving the transmission is doing lots of back in forth in low gears which again is where the most fuel consumption takes place. On the highway it's nothing special because then the hybrids are like any other vehicle at speed. |
