Ford calls C-MAX Energi a "hybrid-plus" because it not only operates just like C-MAX Hybrid, but also features an external charge port and larger lithium-ion battery pack so owners can plug in the vehicles to fully charge the battery using either a standard 120-volt outlet or the available 240-volt charge station.
