There are a number of postings on fuel economy on the 2013 Fusion Hybrid, but most are "spot" or "trend" reports with no indication of rate of change. I am seeking information on improvement over break-in, mileage, etc in that I am not pleased with my fuel economy on my second Hybrid. Off the lot, I got 36 mph and am up to 38.3 over 2000 miles and one month. Any insights as to probability of getting 43+, or at least over 40? On our first '13 Hybrid, we got 40 off the lot and it quickly improved to 43.2 (was in an accident at 4 months and 4200 miles, so ended that history). Otherwise, am extremely pleased with the Hybrid, including walking away with no injuries from the accident in which we were rear ended and our car was a total loss.
