I am new here and since getting my C-Max almost a week ago, I have been trying to drive carefully and learn these new hybrid driving techniques. The car computer is saying 48.6 average MPG for my first 200 miles. My two questions for the veterans out there are first, how accurate is this car computer in estimating actual gas mileage, and second, doesn't this average seem a bit whacky for a new, unbroken-in motor?
