My thoughts for my C-MAX SEL that I really like to drive (I have 3000 miles). I find the computer to be off by about 2 mpg in Ford's favor when refilling the tank. Since I bought it in September, I was first getting good mileage 43 to 44mpg on my 15 mi commute to work. After driving it a week, I was getting the 45 to 51mpg consistently. Part of my commute is 9 miles of I-90 and I never drove it over 62 mph, part was waiting to get on the entrance ramp and 3 miles of stop and go. I am not afraid to punch the throttle when passing or pulling out of a toll gate. However, I do pull off gently to stay in EV mode when in stop and go...unless I need to quickly merge. Now that it's cold (I live in Boston), I get 38 to 44 on the way to work depending on if I stop at the gym first (engine is a bit warmer when making my final trek to work). It's not uncommon for my 1st leg to the gym to read 16 mpg as I have the lights, heater and heated seats on and it just gets warm when I turn it off. My last tank measurement which included 285 miles of driving in the rain and snow averaged 38.5 mpg. Again, I kept it running no more than 62 mph unless needing to pass or pulse it to get it into EV mode. I feel duped buying this for the 47 mpg mileage, but I love the way it drives, the space, the interior.....and the Mytouch. I hope the promised mileage returns in the spring, just like the flowers in my garden. Oh yeah....There are some initial software issues that will make the car appear not to start....it will go into battery safe mode by itself and only then it will allow you to start after about 15 min. So if your car appears to be alive, but won't start, be patient and you'll get it started again. Yeah, that pissed me off, but the dealer said Ford was aware of it and had a fix... so that, and a loaner car eased the pain. Am I a fool for still liking this car?
