Fusion Hybrid and Fusion Energi are technology-packed electrified vehicles that offer an advanced EcoGuide system to provide drivers real-time coaching to get even better fuel economy. Fusion Energi features a 7.6-kilowatt-hour lithium-ion battery for an expected range of 19 miles using electric power only. The car automatically switches to an efficient 2.0-liter gasoline engine when the battery is depleted, allowing customers to drive more than 500 miles.
