According to Ford, its ENERGI plug-in will have: Ford's 47-mpg C-MAX has special gas-mileage button EPA ratings not out yet. First time I've read this: "will hit 85 miles per hour on electric power alone." Edit: OK, I believe this writer is combing both the c-max hybrid and the energi into one car. LOL The mpg figures are, of course, for the hybrid but then he goes on to talk about energi plug-in ev button news which should get WAY better mpg. Confusing yet the avg. joe will never notice. Needs clarification. Here's a better, more car oriented, link (bold emphasis is mine): 2013 Ford C-MAX Hybrid family car will achieve an amazing 47 mpg "The new 2013 Ford C-MAX Hybrid gets 47 mpg according to the EPA. If you are wondering if that is city or highway mileage the answer is “Yes!” Rated 47 for both city and highway, this 5 passenger vehicle will set the new standard for reasonably priced fuel misers that can be used for day to day tasks. The Prius V, on the market now about one year, “only” gets 40 mpg around town and has a combined rating of 42 mpg. That is a significant difference."
