The guessing is over, as Ford has revealed full EPA mileage figures for its 2013 Fusion Energi plug-in hybrid, after teasing its 108 MPGe highway rating a few weeks back.
Joining the C-Max Energi in Ford's plug-in hybrid lineup, the Fusion Energi touts a combined 100 MPGe in blended electric mode, with city and highway figures of 108 and 92 MPGe.
In regular hybrid mode, combined mileage is 43 mpg, with 44 mpg city and 41 31 highway.
The Fusion's official range is 620 miles, 21 of those on electricity alone. Electric-only top speed is an impressive 85 mph, meaning silent highway cruising.
That means the Fusion Energi offers better electric range than the Toyota Prius Plug-In (11 miles) and Honda Accord Plug-In (13 miles), but less than the range-extended Chevrolet Volt.
The figures in hybrid mode also lag behind those of the Prius and Accord plug-ins, the former managing 50 mpg combined, the latter 46 combined. The Accord plug-in also offers greater blended efficiency, with an official 115 MPGe.
The Volt, for comparison, gets 98 MPGe in electric mode, and 37 combined on gasoline for the 2013 model year--but as any Volt owner is sure to tell you, the near-40 mile electric range provides the opportunity for some spectacular gas station avoidance--more so than its rivals can offer.
So where does that leave the Ford? Electrically, in a better position than its rivals, though the Prius may still rule on long, gasoline-fueled journeys.
The choice may come down to how they each drive, and how many miles of electric range you require--but there's no doubt that the choice of competitive plug-in hybrids is improving all the time.
