year around. Don't believe Toyota's listed ratings. In town it's stop and go, ad nauseam. I get about 43 mpg in the summer and 38 mpg in the winter. I don't jump start at intersections, but I don't hold up traffic by creeping out either. I don't know how they are able to get away saying 60 in the city unless it's all beltline driving. Most towns don't have beltlines. (Besides, they are highways) Believe Consumers Reports when they say it's 46 mpg all around average. Like most people, I drive short trips in town and not much highway travel.
I heard the EPA is finally waking up and changing their method to calculate city driving. Up to now they cater to big business and not the consumer.
All in all. I love my Prius. I drive about 12k miles per year. No matter how much Toyota and other companies lie, I still get two to three times the mileage I've ever got on any compact car.
