Huh? Prius owners never get close to the sticker MPG? I get 50 - 52 MPG average every tank of gas. Mostly Highway driving and the roads are flat. City I can get a little more. If there are hills then my mileage drops.

I just drove to Las Vegas and averaged 50.5 MPG round trip from Los Angeles so I would say that the Prius delivers close to the advertised MPG. I drove between 70 and 80 miles per hour depending on traffic conditions.

I don't drive my Prius hard but I don't drive like a little old lady either. It's a game that you need to play with the accellerator. No need to punch the gas off the line or have your foot on the gas when you know you have a stop up ahead.

With a slight change in driving style you can definitely come close to the 60/51 that Toyota advertises.
