Well, BBW's Pruis gets some ridiculous mileage, around 45 I think per gallon. It ain't free, but its a lot more affordable than my Rav4 wtih her 22 mpg. The Prius has a wonderful electronic display which shows you when energy is being generated into the electrical system by braking, for example, or coasting, and when it is drawing on the battery and when it is drawing on the engine, It constantly displays your current MPG moment by moment so it becomes a great game to driver so as to maximize the MPG figure.
