According to the EPA, Ford’s new Fusion Energi plug-in hybrid has a range of 21 miles in electric-only mode, and a 620-mile range using dino juice. With a 100 MPGe combined fuel economy rating, there’s no doubt that the new sedan is a gas saver.

In fact, Ford is making fuel economy a centerpiece of its strategy these days. Fusion Energi is the brand’s fifth electrified vehicle to launch in the past year, and its hybrid models are racking up impressive sales – the company sold a record 19,554 hybrid vehicles in the fourth quarter of 2012.

Ford’s press releases make much of the fact that its new PHEVs beat Toyota’s Prius Plug-in Hybrid in most of the important specs, from electric range to fuel economy to top electric-only speed to total horsepower. Of course, the Ford C-MAX hatchback makes a better comparison to the Prius. The Fusion Energi sedan might more logically be compared to the Chevy Volt (or it might not – the Fusion is a tad bigger, and has a bigger gas engine).

Prospective buyers should check out the “Compare Side-by-Side” feature on the EPA’s site at www.fueleconomy.gov. Punching in these four models (PPI, Volt, Fusion Energi, C-MAX Energi) reveals some interesting facts. While the Volt has the longest electric range (38 miles), all four PHEVs have exactly the same projected five-year fuel savings ($6,250).
