Well guys I just filled my first tank after getting the car a few days ago. Hand calculated 41.7 mpg. So I dive 68+ miles a day, and I would say 80% highway and 20 city. There is a 10 mile stretch where it is all hills. And my average speed on the highway is around 65-75 mph. I have to say that I am highly impressed with the number I got on the first tank.
