I also purchased Blizzak's ... Here is my thread on MPG Gain http://fordfusionhybridforum.com/topic/9446-125-mpg-jump-pcm-or-tires/

Tire Size: 215/55/17 --- Steelies for the win!!! :)

How about the law of averages .... I've taken this same trip 50+ times and never once have I seen a MPG number above 40 until Saturday.

How do you figure that those two things go together ?

 

I bet that some times during the year the wind DOES blow from NE to SW along that road.

Lake Michigan creates it's own weather / prevailing wind

 

How is the coast down now, any different? Does it seem like it slows down less when you lift your foot?

I haven't notice any real difference ... No one thinks it could be the PCM update?

A good tail wind.

cruise control on.

climate turned off.

higher tire pressure.

a less topped off gas fill.

Car gets better mileage with age.

So many variables.

 

Or a combination of any.

It's better to MPG rate the tank rather than rate each trip.

My trip computer is much higher than my Fuelly tracking.

12.5% is too big to trust.

 

But enjoy the moment and do it again tomorrow.. :)

The drive is NE to SW along lake Michigan so there is no tail wind

I always use cruise for this trip (set at 60MPH)

It was 28-38 degrees outside and the heat was set to auto (72)

I am religious about my tire pressure checks ... the old tires were always at the correct PSI

I always fill up before I leave (almost always at the same gas station).

I took the trip two weeks ago in 65 degree weather and got the normal 40 MPG

.... I guess we will see what happens next time... but something has changed. I know this car too well ...

A different tire diameter would account for it or a 15 mph tailwind.

Same exact diameter wheel and I have literally driven this same route 50 time with extremely consistent MPG results.

Last week I had snow tires put on my car and had FIELD SERVICE ACTION NUMBER: 14E02 completed on my car.

I have a specific trip to my hometown that I take very frequently (2.5 hours on cruise).

I took the trip last night and ended up with 45 MPG

When I usually take the same trip with my stock 18" wheels (prior to the update) I would get right around 40 MPG.

I was expecting my snow tires to KILL my MPG ... but now I am stumped

?!

My car has 29,000 miles on it and has been extremely consistent at sucking in the MPG category.

I put in the LED Fogs last week :)

31 MPG after 27,000 miles ....

.... My lifetime average at 27,000 miles is 31 MPG .... Ford says it is "normal" .... Thats what I get for buying a first production run car

got the update today. no difference so far in mpgs. really, really having buyer's remorse. wish I could trade it in and not lose a ton. :((((((

I love the car.. but my MPG is terrible. What is your lifetime average?

Since the update on Tuesday...

You guys make me want to drive my car off a cliff... My average since the update is 29.8 MPG ....

Did they retest it now that the weather has warmed up? From that letter, if they get the same results, then you can slam it back in their face.

They did back in June and got 41 MPG ... which they say is normal ...

Can you share what they said in the letter? Maybe we can somehow help you.

 

Have you tried going to another dealership and test driving a new FFH?

this is a screen shot of the letter; they never responded to my email about the second MPG test

I have not tried going to another dealership and test driving another car... seems like a waste of time to confirm what I already know

One thing I have noticed is the rev meter on the left side no longer turns yellow if you floor it. Also the MPG instantaneous doesn't turn yellow when your mpg drops low

Mines below, it is unfortunately accurate. Mostly 55 mph short trips

If someone personally would claim that yes > YMWW but if the dealer or in your case a Ford field engineer does the test and they can get close something is wrong. The way he was drove your ca he should have gotten 55 MPG with ease.

I drove 55 mph for two hours straight (adaptive eco cruise on) and only returned 42 MPG. I can confirm Ford claims that 37/41 MPG is "normal" (I have a letter from ford stating it). My best tank of gas was 38 MPG

Is the

 

What needs to be done is some driver and car testing. You need to drive a FFH known to get good gas mileage to see what you get. Then someone who tends to get really good gas mileage needs to drive your FFH to see what they get driving it. This would help isolate how much of the issue is car related and how much is driver related.

I would love to try this; I live in Northern Michigan (Traverse City), and I visit Grand Rapids/ Muskegon often. If anyone would like to help me with this I would be interested in the results. The Ford dealership has done two fuel economy test on my car and they only got 37MPG and 41MPG...

still getting 31-35 MPG .... so frustrated ... 11,000 miles on the car and never had a tank anywhere near 40MPG ...

I think I have the honor of having the worst fuel economy of any 2013 FFH owner... Just got the update today... Hope this helps my car

Might not matter tho... I started the lemon law procedure earlier this week for a headliner issue

Greetings From Traverse City

The outside temp defiantly makes a difference, I think warming up my car in 60-70 degree weather would result in a lot less gas loss but my problem is terrible gas mileage in cold weather... So warming my car up in freezing weather is counter productive

This is my 2cents on the topic...

I have 7000 miles on my Hybrid and am at a lifetime average of 30 MPG

I tried numerous experiments this winter with warming up my car... This is the result

These trips were the same route, same time of day, and similar temps**

Trip #1 Warmed up the car for 10 minutes then drove to work

Outside temp 35 Degrees

Second trip previous day

Outside temp 35 Degrees

Car Warmed up for ten minutes, turned off, turned on and the driven to work

I see your problem! You took the Fusion badge off and negatively altered the aerodynamic qualities of the vehicle! Better put it back!

If only that we're the solution ... I'm at 6000 miles and an average of 30mpg lifetime :( the badge is still on the car... It's just under that decal
