The C-MAX Energi uses an air cooling system to regulate battery temperature and help maximize battery life, so you can get the most miles out of each charge. Another feature of the C-MAX Energi is EV mode. This is a button that lets you switch the vehicle between EV Now, Auto EV and EV Later. So you can choose which mode to drive in – electric only, gasoline only, or a combination of gas and electric.
