 We've had our 07 Versa S Hatchback for 7 months now and couldn't be happier.  I keep detailed mpg records and so far we've averaged 28.8 mpg driving 1000 mi/month of about 40% hwy, 60% city.  When we get out on the highway for a long trip, we always get at least 31-32 mpg and that's driving it 70+ mph.  We had one fill-up of almost all city driving during the winter and still got 27 mpg!  If you get less than 27, it's broken!
