Thanks 'Jmckinley' for posting the Ford letter, and I too have now experienced the low hwy mpg. Normally my drive to work is 50% city and 50% hwy and I have had high of 44 mpg avg back October but now dropped to around 40 mpg and have about 5800 miles on the odometer. I recently had to take a 250 mile trip for work that was mostly expressway from Detroit to Ludington MI with stops in Lansing and Muskegon. The elevation is pretty flat and air temps in low 20s and my speed was 70-75mph which resulted in a 31-32 mpg. Two days later the return trip was not much better at 32.5 mpg avg. I know my speeds where a little high at 72 but these are typical for freeway. I could have taken 2 lane roads at 55 mph but this trip was for work and not for sight seeing. l agree that the speed is a big factor and it seems like you would need to maintain a 48 mph avg to get a 47 mpg hwy given the ambient temperatures and break in period for the car. I don't see why Ford engineers chose 62 mph for the EV mode, I mean this works fine for the city roads but 72 mph would be better for the expressway. I know there must be some transmission and electric motor heating limitations requiring this 62 mph limit, but given the low air temperatures it seems like there should be some kind of mph range for EV mode. The whole trip the car never goes into EV mode, also the ECO cruise did not make a difference. I can drive slow in right lane but many times I become a hazard since the typical speeds are 70 mph+ out in the country. It seems to me that the Ford engineers missed the EV mode by 10 mph. I get it that "spirited" driving will hurt your mpg, but 72 mph on the freeway is pretty typical for Michigan expressways.
