FEH - '09 vs '10
No one has entered a '10 FEH in our Mileage Log to compare the kind of mileage it gets to any of the prior FEH/MMH's. Also, except for Wayne's reviews the FFH is not doing as well as I expected. The change from the 2.3L to the 2.5L was a great improvement in MPG and I know the 2.5L handles E10 much better. Wayne and I are a die hard when it comes to running the A/C and I think this may be the key to the problem. Now that I'm seeing 90's F, I can see condensation dripping from the Aux Battery A/C after parking. I think the heat is improving the efficiency of my engine so the battery A/C is having less of an impact on mileage.
My question is, did the electric A/C take its toll on MPG by robing the HV battery with too much SoC? The 2010's eliminated the Aux battery A/C so cabin A/C is the issue I think. The 2010's also use cabin ventilation now, so does that mean unless the cabin A/C is On the battery will get hotter and be less efficient in hot weather? Running the cabin A/C with all of the other newer electronics can keep the battery SoC below EV levels in city driving is my concern. Was going to an electric A/C compressor before going to a Li Ion plug-in system a bad idea for those people that use the A/C in city driving? Should Ford have stayed with a belt driven A/C compressor until the plug-in change? Any thoughts?
