lolder Report post Posted April 22, 2015 No, you want the ICE to run more. Ford made a mistake when they upped the max EV speed to 86 mph. EV is less efficient than the ICE at speeds over about 40 mph. Ford was clutching at straws trying to meet their EPA numbers and finally revised them downwards 4 mpg and made a cash payment to owners. Whenever you need substantial power during acceleration or hill climbing or higher speeds, the ICE should be on. Don't milk the EV mode. Quote Share this post Link to post Share on other sites
