It's rated 5.0 liter per 100 km (combined city/Hwy), and the reviewer got 7, over 2 weeks. Not way out of line, and that latter number sounds more on the mark, for a mid-size hybrid. He doesn't say if it's calculated or displayed. That might not matter: at least with our civic hybrid displayed fuel economy was either spot-on, or slightly pessimistic.
Over the winter, that's not too bad. I think reviewers get around 6 or high 5s for the Prius in the winter.
