The Ford Fusion Energi is the plug-in hybrid version of Ford’s Fusion sedan. The Fusion Energi was announced at the North American International Auto Show in Ford’s hometown of Detroit in 2012, as part of an overall update to the Ford Fusion model lineup. Based on the announcement, as of the 2013 model year, the Ford Fusion was the first sedan to be offered with a traditional gasoline engine, a gasoline-electric hybrid drivetrain, or a plug-in hybrid drivetrain. Sales of the Ford Fusion Energi began in the United States and Canada in February of 2013, just a few months following the release of the Fusion and Fusion Hybrid versions. The Ford Fusion Hybrid family, comprised of both the gasoline-electric hybrid version and the plug-in hybrid Fusion Energi, won the 2013 Green Car of the Year award. The Ford Fusion Energi competes primarily with the Toyota Prius Plug-in hybrid, as well as other traditional gasoline-electric hybrid vehicles. 

The gasoline-electric hybrid version of the Ford Fusion was announced in 2005, at the North American International Auto Show in Detroit. It wasn’t available until the 2010 model year, though, and the 2013 model year update marks its second generation. The Ford Fusion Energi shares several components with the Fusion Hybrid. All three versions of the Ford Fusion are visually similar, with only subtle differences in the cars’ badges to clue in casual observers to the cars’ differences. The Fusion Energi also uses the same 2-liter four-cylinder gasoline engine as the Fusion Hybrid to help assist the electric motor. The electric motor is an 88 kW permanent magnet unit, and the system uses a 7.6 kW lithium-ion battery pack. The Fusion Energi’s drivetrain is rated for 195 horsepower and is paired to an electric continuously variable transmission. 

The Fusion Energi differs from the Fusion Hybrid in that the Fusion Energi can run on electric power only until the battery is depleted, and then the car functions like a regular gasoline-electric hybrid until it is recharged. This gives the driver the option of managing trips so that the car functions most often like an electric vehicle. The Fusion Energi can travel 21 miles on electric power alone, and the top speed of the Fusion Energi, in electric mode, is 85 mph. With a fully charged battery and a full tank of gas, the Fusion Energi has a range of 620 miles. The Environmental Protection Agency determined the Fusion Energi has combined city/highway fuel economy in electric mode at the gasoline equivalent of 100 miles per gallon, and the car yields 108 miles per gallon equivalent in the city and 92 on the highway. In hybrid mode, the Fusion Energi yields combined fuel economy of 43 miles per gallon.

The Fusion Energi fully charges in 7 hours on 120-volt power. If a 240-volt outlet or charging station is available, charging time is cut to just two and a half hours. Buyers of the Fusion Energi can opt for a 240-volt home charging station to be rolled into the car’s price. Like the Fusion, the Ford Fusion Energi is a front-engine, front-wheel-drive car that can seat five occupants. The Fusion Energi comes with standard 17-inch aluminum wheels. It features a regenerative braking system to recapture and reuse some of the energy that’s lost when the car is braked to a stop. It also features many of the standard and optional features found on the other Ford Fusion models, such as the MyFord Touch driver information system, a rear view camera, lane assist, active park assist, LED taillamps, projector headlamps, and adaptive cruise control.
