1. Always look ahead. If a light turns red down the road start braking GENTLEY now.
This is how you get the best regen which charges the battery, and helps a lot with mpg.
2. Accelerate slowly, this way you will be able to stay in EV mode as long as possible.
Also always keep to the speed limit.
3. I find that the engage screen on the C-max is the most informative. Watch the screen to see when you are engaging the engine. Once you learn what you do that turns the engine on, you can help stop it, or at least prevent it from happening as much.
4. I know all of these steps are pretty basic, but once you learn to master all of these steps, you will get great mpg. Please message me with any other questions.
