Thanks for all the info.  I never use the auto mode.  Perhaps I'll give it a try.

I lived in Vermont for two years/winters.  At the time, I drove a Ford minivan.  For the entire time I was there, there were only two days when I road to work with someone who had a Subaru, and one day when I said there was no way I was driving my car down the hill I lived on.  So, from my personal experience with front wheel drive, I think you'll be fine with good snow tires.

However, do know that your gas mileage will go down with the cold weather.  The batteries are not as efficient in the cold.

t h a n k s     ggggrrrrrr we run ac 8 months a yr

We do, too.  It's just too humid here to rely on just opening the windows.  I did, however, set the AC for 76 degrees instead of 63, where I was running it.  It was a bit overcast yesterday, so the car was not as hot.  I'll keep giving that a try.  The question would be - is it better to run the AC at a higher temp (76) and a higher fan speed than to run it at a lower temp and lower fan speed.  I did discover that above 76, there was no way to be comfortable in the car.

It's about 86 degrees out today.  I decided to take a look at how much of a power drain the AC is...and it is a lot.

Have you changed where you purchase gas? I had a few weeks where my MPG dipped.. Nothing environmentally changed, but I did fill up at a different gas station. Just my two cents...

I go to a variety of places.  I'll see if I can figure out a pattern.

To respond to all of your comments:

set the a/c temp higher than 68F , To maximize my mileage I set my A/C at this early time of year to 73F so the compressor does not run as long.

I gave that a try on the way home today.  89 degrees outside this afternoon.  42.9 mpg.  This morning - no air conditioning and 41.9 mpg.

AC obviously takes power and reduces fuel economy in all vehicles.  Once we are used to summer temperatures, we set our AC to 76-80 F for longer trips and find it comfortable. If it is somewhat cloudy with less direct sun through the windows then higher setting is OK.  Also one can turn on recirculation for shorter trips with AC and that reduces power use (not advised for longer trips).

 

Window tinting with a good quality material reduces solar heating of the interior and reduces power draw from the AC.

My windows are tinted.

I generally always have the air on recirculation.  Why is it not advised for longer trips?  I remember being confused about this before.

Tinting does help somewhat but when you have a dark interior as I do, it still gets warm. I've been using the AC on and off again and like I have posted before, it will drain the main batts a lil faster than usual and naturally, your regen is not as fast either - gotta give something up for the comfort of the coolness. With that in mind, my thoughts is that going from 47MPG to 43MPG, it ain't too bad. With the extra drain and less regen in mind, using P&G helps but I suspect you're using the EV at the tail end of the glide to push the extra miles and probably draining the batts to the low point. I could be wrong but hey, I can only work with what was posted so I am making some assumptions. The better strategy is to keep the battery working on the "high side", use P&G to build up to 75% and work it down to no less than 50%, rise and repeat. Really feather the EV (1/2 or less) to maintain the speed and work this region. You will tire of it so just throw it on ICE High MPG to help with the regen but be smart with it as the downgrades, turn it off and do some P&G so you save the gas. Thats the way I play so it may or may not work for you and your CMax.

 

Use AC and enjoy the trip, no sense in sweating for a few bucks of gas. Can't fight physics nor mother nature. Hope this helps  :)

That sounds way too complicated!  :)

I'm mainly worried about failing batteries, etc.  But if that doesn't seem like the cause, then I'm fine with the lowered mileage.  Though, I would prefer to be hitting 50 again.

Thanks everyone.

When I first started driving the C-Max, I was getting between 47 and 50 mpg.  But now I'm  getting a steady 43.  Right now I'm running the air conditioning, but that wasn't the case a few weeks ago.  

My miles are mostly highway.  Sometimes in traffic, sometimes not.  I've tried P & G and I've been working hard at finding that "sweet spot"  when there is no traffic on the highway.

I'm about to hit 5,000 miles.  

Thoughts?

I figured that by the time I need to replace the batteries, the price would have come down significantly due to competition.

I'd like to have all of the dashboard displays and gauges visible when I'm wearing sunglasses on a bright sunny day. Between the excessive streaks of glare reflecting off of the nearby decorative bright trim and the small-yet-stylishly-faint text of some of the readouts (like outside temperature, for example), it makes me wonder if the sun ever shines at the Ford R&D center.

I can barely see the temperature and speed limit (on the right-hand nav screen) because the font is so small and I don't drive with reading glasses on.  :)

Also is there a list of stuff that is supposed to come with the car?

 

(Sadly my $30k car I ordered was swapped by the dealer at the last minute for a test driven car that has more than a few issues and finding out after the fact that I'm missing some items I should have gotten at time of purchase)

How can your dealer swap out the car?????  That sounds like a lawsuit of some sort.  I also have a test driven car and am missing a few things - like a second key.  The dealer is working on it.

I haven't seen a list of what is supposed to come with the car.

Heartbreaking.  But I'm glad no one was hurt.

I think you can turn them off by just clicking past it.  

I parked next to someone with a Prius V a few weeks ago.  He and I compared cars.  I honestly think there is no way the CMax is going to beat the V in cargo space.  However, if you are creative in how you pack things, then it isn't a problem.  

I've actually had issues in parking lots with people not moving out of my way because they had no idea I was trying to leave.

pressing unlock on the remote for ~5sec while walking to my hot car, and watching the windows roll down to let-out the hot air.

I did not know about this.  I just gave it a try, and it works!  Yay!  I live in Florida!

I have changed phones and cars quite a bit in the last year.  I've unsynced and resynced numerous times.  It's not that difficult.

I went from a 2013 escape ro a 2013 cmax and my insurance went up.

I don't know about the audio on off. But to end the call. Push the "button" and hold it down until the call disconnects.

Mine is fine.

I just had the dealer check my alignment. I drive mostly on the highway and I don't really have an issue with it. Perhaps mine isn't as bad as others are experiencing

In the ford flex I rented, I got 19 mpg.

I've noticed that wind kills my mpg. It's too bad.

Well, no. You cannot option up without getting the leather seats. And some of us were not a le to take the option to wait 2 months for their car. The world is not a one size fits all scenario.

Aha!  I'll give it a try.

I've noticed lower mileage numbers the last few weeks.  I'm still trying to figure out why.  

And Passover!
