If you're keeping score at home, the price difference between the C-Max Energi and the regular Ford C-Max is exactly $4550. What does the extra money get you? A big surprise when you pop the C-Max Energi's optional power liftgate: 5.3 cubic feet of the cargo area is filled with a 7.8 kWh battery pack, charged exclusively by the plug located just beneath the A-pillar window insert. It's enough to power the C-Max, gas-free, for up to 21 miles.
