http://Future-Ford.com 888-656-7577 The main difference between the Ford C-MAX Hybrid and the C-MAX Energi is the plug-in capability. The C-MAX Energi has an external charge port and a larger state-of-the-art lithium-ion battery than the C-MAX Hybrid, for an electric-only driving experience. The vehicle can fully charge overnight using a standard 120V outlet or in less than three hours using a 240V charging station outlet.
