EPA city MPG estimate difference: FWD 2011 vs. 2012

[new to ford]

According to Ford explorer brochures:

2011 3.5L FWD:
City 17 MPG
Highway 25 MPG

2012 3.5L FWD:
City 18 MPG
Highway 25 MPG

Is this difference in city EPA estimates between 2011 vs. 2012 a typo on the brochures?
OR, did they really change something on vehicle, for example engine calibration?
If that's the case, then I am missing 1 MPG city compared to the vs. 2012

I have a 2012 LTD, fwd, I made a 120 mile trip, and average 18.7 on freeway/ city, I'm getting about 1.2 better per tank of gas. Some older threads, guys were getting better mileage after 5 k or better.

This was discussed in an earlier thread, Ford made some transmission programming tweaks and EPA retested and got a better score.

I have a question please:

Coud the 2011 transmission model be reprogrammed similar to the 2011?
If so, would the dealers do it?

Thanks for posting that other thread, that sheds light to this.
That post went completely unnoticed by me, but I know why.. it took place when I was on vacation
