Highway MPG

[dnorris78]

I recently took a very long road trip from the Carolina's to central Illinois and back.  I noticed some interesting things about the mileage on my 2013 FFE.  There doesn't seem to be a bit of different in instantaneous mileage readout at 55 mph, 65 mph or 75 mph.  By tracking fill ups I get an average of 55 mpg on that road trip.  Has anyone experienced this on a road trip?

I have too much of a lead foot to get 55mpg on a trip, I tend to get anywhere between 46 and 40.

 

Speed absolutely affects your mileage.

You are both still getting well higher than Ford's now DERATED 38 MPG for hybrid mode.  I still don't understand why they derated the Energi. 43 mpg was dead on for even the most aggressive drivers, and conservative for most of us now acclimated to driving a hybrid and being energi conscious.

It's probably due to the winter mileage.  During the winter when it was especially cold, I had MPGe ratings in the 20's for my normally ~160MPGe commute (in late spring through early fall).  Battery range estimates were about 12 with climate, 16 without.  In some cases even with preconditioning, my ICE would kick on a mile after I left the house and would stay on until I got to the office.  And then Oil Maintenance mode got me about 3 or 4 times during the cold season.

 

Summer ratings for me are phenomenal, but the cold season is abysmal. :)
