The Fusion Energi plug-in hybrid uses a 2.0-liter four-cylinder engine in combination with an electric motor powered by a lithium-ion battery. To link the gas engine and electric motor together, an electronic continuously variable transmission, also known as an eCVT, is used to optimally match the power and gearing. Safety features include anti-lock brakes with panic brake assist, AdvanceTrac electronic stability and traction control, LED taillights, daytime running lights, LED headlamps and fog lamps, security system, eight-airbags and a tire pressure monitoring system. Also available are SYNC 3, auto high-beams, lane keeping assist, pre-collision assist with pedestrian detection.
For 2017, the Fusion Energi has been refreshed inside and out and adds a new fully-loaded Platinum trim.
