Just an observation; if it is not interesting to you I hope you'll just ignore the posts. I've noticed the same thing in my C-Max Energi - at highway speeds the two vehicles operate similarly (because I turn off my EV battery reserve for later off-highway driving, leaving it in the exact same mode as the Hybrid C-Max). Whenever I'm using the ICE, the MPG guage is most often at or below 20 if there is any engine load on the vehicle at all. It was interesting to see it in your numbers, as a confirmation. I actually think that the 2.0L may a bit small for a 3500 lb vehicle, IMHO. That is similar weight to the previoius generation Escape Hybrid, which had a 2.5L engine. GaryG, and exceptional hypermiiler who can be found on these forums, owned a 2009 FEH, and he got better hybrid mileage than with the C-Max. I suspect Ford used the smaller engine for some reason other than maximum design, perhaps because it was a common engine overseas, or maybe for size of the engine compartment, or something. BTW, I admire yours and everyone elses great numbers on the Hybrid C-Max, don't think I don't appreciate the great job of driving you show! I glance into this forum to get tips for my own driving, and because most of the features are identical between the Energi and Hybrid models - I'm not "trolling".
