I think it's a good time to explain how to improve the efficiency/MPG's of CMAX/Fusion Hybrids again..
1. All the energy to move the car comes from burning gasoline in the ICE, so to start with the more efficient the ICE is, the better the gas mileage is going to be.
2. From FORD we know that the approx. operating temperature range of the ICE is 202*F to 212*F, I typically run between 215*F to 230*F with no negative effects. My last oil change I got my best BlackStone Lab numbers with 153k miles.
3. The CMAX/Fusion Hybrid being unable to get up to operating temps is the main cause of poor MPG's especially in City and cold weather driving. This is why Grill Covers are so important to Gas Mileage, getting the WT to come up faster staying above 202*F and should be standard on all CMAX/Fusion Hybrid vehicles. IMO Also Grill Covers improve HWY MPG's up to 2 mpg by cutting down aerodynamic drag
4. From our 4.5 yrs of testing, 2 Bars acceleration seems to get the best gas mileage so use it whenever possible. And again the procedure is accelerating at 2 Bars to 5 mph over desired speed and then let off the accelerator so ICE will shut off and EV Mode will engage. Then try to maintain speed in EV until ICE kicks in again and repeat by accelerate at 2 Bars to 5 mph over speed limit.
