The 2016 Ford C-MAX Energi Plug-In Hybrid gives you the option of plugging in – or not. The main difference between C-MAX Hybrid and C-MAX Energi is the plug-in capability. C-MAX Energi has an external charge port and a larger advanced lithium-ion battery than the lithium-ion battery in C-MAX Hybrid, for an all-electric driving experience. The vehicle can fully charge overnight, using the standard 120-volt convenience cord, or in 2.5 hours, using the available AeroVironment 240-volt home charging station. C-MAX Energi utilizes a lithium-ion battery and electric motor with a gasoline engine.
