Now that I got your attention it would appear from Fuelly.com CMAX Average MPG results that alot of CMAX drivers aren't driving their CMAX's the way they were designed to be driven by breaking the 2 Bar Acceleration Rule. To get the best gas mileage you need to Drive using the Empower Display 2 Bar Power Acceleration Rule where the ICE runs the most efficiently and charges the HVB the fastest.
When driving you can use a mild Pulse and Glide strategy by accelerating at 2 BARS to around 5 mph over the speed you want to cruise at then let off of the accelerator for a second to allow EV to engage then back on to maintain speed until HVB SOC gets low enough for ICE to start then accelerate at 2 bars to 5mph over and repeat. This is worth atleast 2 MPG's and probably more.
BTW covering up the grills is worth another 2-4 mpg. http://fordcmaxhybri...ng-2-5-mpg-gain
It would be nice if members would comment on their results.
Happy CMAX Motoring
