I am just wondering what kind of range people are getting between fill ups. I know somebody with a second-generation Toyota Prius that is getting roughly 550 km on a tank of gas. This ends up being about 343 miles for the people living in the US. This is with just one bar of fuel remaining in the gas tank. At very optimal summer conditions, and extremely good result would be 750 km or 470 miles. I hate to say it, but it's definitely not a lot better than my Honda Civic which is 1994. The gas tank sizes are exactly the same in both cars. This is a 2009 model, so one would expect that it has the latest firmware and any software bugs removed. The extremely long range can only be achieved during a couple months of the summer. Soon as it starts getting a little bit cool, the fuel economy sinks right down to the short range. The car is not driven on short trips, it does a 40 minute commute one-way everyday. What kind of range are you getting out of regular gasoline which is 87 octane?
