  I've calculated the long-term average by tracking how much fuel I put in the tank and how much the odometer goes up, over many fillups. From that I get about 55mpg. The efficiency in specific situations is from the on board computer. How do you calculate it? > In the real world, I haven't seen hybrid drivers that actually get what's advertised Come over to priuschat.com sometime and you'll find plenty of them that get the advertised numbers and better. EDIT: Or check out fuelly, which calculates efficiency using the same method and you'll find plenty of people who get better than the official numbers: http://www.fuelly.com/car/toyota/prius http://www.fuelly.com/car/toyota/prius

    Wow! I never thought about looking at how much I've spent on fuel over a long period of time. The problem for me is that we have multiple cars. I currently drive until the red light comes on, fill up, and look at the trip counter to see how many miles I've driven since my last fill-up. I then reset the trip counter and repeat. My time is spent in mixed highway and city traffic. I'll have to look at modern hybrids once something actually breaks on my car. I'll consider everything equally once it's time to shop again.
