I'm pretty happy with the numbers that they released and it's what i expected with the weight and power.

From looking at the V6 auto vs the V6 manual it seems the auto gets better fuel economy. My guess would be the ecoboost auto is going to be Ford's bread and butter, so I'm guessing a 27mpg combined for the 2.3 ecoboost auto?

Thoughts?

probably. With the V6 being relegated to little more than fleet/rental cars (the lack of any V6 premium trim signals that) then yeah, I'd say the 2.3 EB will be the choice for people who don't want to stump up for the 5.0. Going by the build & price on the Ford site, you can load up an Ecoboost just like you can a GT. the available options on the V6 are pretty sparse.

That is true. I was hoping it would be a couple mpg's more but I mean its making a ton of power for that engine size.

Yes, there is a very well defined EPA test cycle to determine the FE label of every car. There is also a modification factor to lower the rating to account for more real world driving since nobody drives as carefully as the test cycle. This is why it is easy to get a better number than published especially on the highway. The modifier is about 20%. So if a vehicle attains 20 MPG in the test then the published number is 16 MPG. The need for this modifier is especially true with the Ecoboost engines as a boosted engine seems to be more sensitive to aggressive driving practices than a non-boosted engine.

Anyway, there is no guess or debate over the label data as it is available for any vehicle here (including information on how the measured data is modified and why):

New to the forums. Took del of EB/prem/auto 2 wks ago. Also have a 2011/6/auto. With same driver and roads, I was getting about 22 overall with the 6 and highest with cruise-control on hwy of about 29. With the stock EB (during break-in) I'm getting about 28 combined and 34 on hwy using regular gas.... I should get a little better with premium (and after break-in).. Not a huge difference from the 6, but much better than the 8 of course.

Just took my EB/Manual on a road trip and avg 34mpg using premium. Not sure if you will see a huge difference in fuel grades. But also I did not use cruise on my trip.

Just for the heck of it, I tried to see what the max gas mileage might be under optimum conditions.... Instead of 75MPH I took a test trip at 60MPH and economized my driving (driving with minimum braking/acceleration and A/C off. The best I could do was about 40MPG, then I just had to put the A/C back on and MPG dropped under 40 (about 38-39). Nice numbers, but realistically, @75 MPH with A/C on and occasional spurts for passing, I've been getting about 34 pretty consistently. With sporty driving on more curvy back-roads, the 2.3T is a blast, but also MPG suffers ....MPG drops to under 30 very quickly, averaging about 26-28. It's all good.

4k into mine with 2 longer road trips and am at about 26. I noticed at 65 we got about 33 for the tank but at 85 it was closer to 25.
