I have about 5000 miles on my Civic hybrid already and I am averaging 55MPG according to my calculations, and 53MPG according to the on board computer. I drive mainly highway miles with a little city. Car is grear, fun to drive, and handles great, and being able to drive 600 miles on one tank is awesome. Much better handling than the Prius, although I think it has a little better pick-up.
