SO I have had my Cmax for about a month. I've got 4300 miles on it & my MPG isn't great. I'm averaging 33-35mpg & am really disgusted. I bought it with the 47 mpg estimate expecting it to get at least low 40's. Most of my driving is hwy with only maybe 20% in town. IT has been really cold the last 2 weeks. I think warmer weather will help it some. Still I just can't see it ever getting close to that 47mpg. What mileage are you getting?
