C-MAX Energi also gives the driver control over how the vehicle’s power is used through an EV mode button – conveniently mounted in the center stack – that allows switching vehicle operation between three modes. Drivers can opt for electric-only driving without gasoline engine power, normal hybrid mode where the powertrain melds electric and gasoline engine power as appropriate, or a battery-saving mode that reserves the pack power for later use.
C-MAX Energi also has a feature called EV+ that allows for the vehicle to stay in electric-only mode for longer durations by learning frequent destinations. The feature was developed in response to Ford research that found drivers prefer to have their vehicles be in electric-only mode whenever possible, Davis explained. “C-MAX is Ford’s first hybrid-dedicated nameplate in North America, but the ability to offer features like EV+ indicates just how deep our level of understanding and expertise is when it comes to hybrids,” said Davis.
