Even at 48 yesterday we didn't use heat -- my wife and I were dressed warm, though (well, warm for Florida - long pants, which I seldom wear, and an actual jacket).  If we hadn't planned on spending more time outside the car than driving we might have dressed lighter and turned on the heat but as it was it wasn't needed even for a 30 minute journey (which averaged 50.1 mpg -- love our Maximis!)

 

But we may end up turning on the heat if we are out and about at night during December/January (then again, we're old people who like to be warm).

I dont know much about the non-energi packages, but the engergi has auto climate. And I just have it set for 72, rarely do I even think about it.

An incorrectly applied 13b07 shows similarly bad MPGs - so OP, fill us in on the history of your CMax. The fix is to have the dealer look at it and they can re-apply. Remember, this update is really finicky - dealers have to use LAN vs Wifi to apply this update and a few owners here got these issues and they did not know about it initially.

 

Wind plays a huge part, as I found out driving back from Vegas to LA in literally a sand storm (in parts), be lucky to eco cruise 38MPG like those Consumer Report boyz were reporting.

 

I recently did a 200 mile round trip, 50MPG at 65 to 75 mph freeway speeds, P&G and eco-cruise. but 44MPG is about right for eco, no frills easy peasy driving at speed. I had 1 passenger and 2 sets of golf club as load this time :)

 

how do I check the history of this? 

What did the trip display say your FE was? What were the climatic conditions? Extra weight in car? I'd suggest running a controlled test say at 70 mph for 10 miles or so in each direction in hybrid mode and see what the displayed FE is. 25 mpg seems unusually low at 75 - 80 mph but depending on conditions (low temps, rain, head wind), it might not be. I get mid 30s with Eco-cruise set at 78 mph (gps) with AC on in summer.

 

Also, how many miles on your NRG?

I'll try to post in the enregri forum.

Total miles just crossed ~8000, about 3000 of those are ev.

It was cold 20's. But still imho terrible mileage, the trip was the same in both direction, temps very similar, winds were also similar. tires @ 41psi. 2 passengers. inside temp set @ 72.

so my first longer distance trip. Filled up full, then drove 268 miles in one direction, and then the 268 miles back home the next day. The trip down to my location, using hand math - 25mpg, one the way home ~27mpg.

Yes I did drive fast 75-80miles using eco cruise in both directions.  But this mileage is shockingly bad.
