C-Max Hybrid: What Owners Should Know
- The 2013–2018 C-Max Hybrid uses a lithium-ion pack of about 300 volts lying flat under the cargo cover, just behind the rear seatback.
- Its hybrid system is closely related to the 2013+ Fusion Hybrid, so the same fan and control-module checks apply.

- The C-Max Energi plug-in uses a larger battery — call us about it.
