92 MPGe City, 100 MPGe CombinedI know that many of you are looking forward to getting your hands on a 2013 Fusion Energi plug-in, and are looking for as much info as possible on this very promising plug-in hybrid (PHEV). Well, the EPA has released the Fusion Energi's official fuel economy ratings over the holidays, and if they are reliable, they should meet or even exceed expectations for a vehicle of this size.
Based on the EPA's methodology, the 2013 Fusion Energi plug-in gets 108 MPG-equivalent in the city, 92 MPG-equivalent on the highway, and a round combined MPGe of 100. That's 5 MPGe more than the Toyota Prius plug-in in the city, which is where both cars shine.
But Your Mileage May VaryBut as usual, I must warn you about the "MPG-equivalent" way to measure things. Miles per gallon (MPG) is ok to compare gas-only vehicles because, while different driving styles will get different results, at least you are more or less comparing apples to apples. But with plug-in vehicles, the electric-only driving ranges makes a huuuuge difference that must be taken into account, and driving habits matter significantly more.
A good example of this is Jeffrey Kaffee's experience with the Chevrolet Volt. He used only 26 gallons of fuel over 12,000 miles because most of his trips were within the PHEV's electric range. If he had only been driving long distances, his results would be significantly different. So when considering a plug-in, you have to look at your driving needs and habits first.
I'm including the video below because it shows that sometimes you don't need high-tech and expensive prototypes to figure out if something can work. Just using some cardboard boxes, Ford engineers had a pretty good idea of how useable the Fusion Energi's trunk would be with a bigger battery pack:
