Ford states 25% better fuel economy. Are you not good at math?

14mpg + 25%= 17.5mpg

 

In the context of mpg ratings of smaller and lighter vehicles that heatk provides in his post to substantiate, it is unlikely that the F150 with Ecoboost will fully show 25% better economy. Are you not good at understanding the weight/size of vehicles and the effect on gas mileage?

Probably more than you- John Deere makes the most fuel efficient tractor out there and it isn't the heaviest tractor. Plus IF you had read the article it states that a new tranny is coming out as well which not only will be able to handle all of the torque plus help with the fuel mileage. Plus if you had of read the article Ford engineers said 25% so it must be true

 

I'm not sure if we're communicating here, but I just recalled that the EPA ratings on a 2008 Escape with the V6 and AWD are 17 and 22. The F150 weighs at least a ton more, has more frontal area, and the Ecoboost engine is larger.

So if they can get 17.5 mpg city out of an F150, that'd be pretty good....I just don't think that will be happening.

Actually i am very good at math. Ecoboost in car = 17 mpg city + Ecoboost in CUV = 16 mpg doesn't = 17.5-18mpg in a bigger, heavier,less aerodynamic truck. I really do hope it does get great mileage but am not gonna be shocked when it comes out with a 15 city rating which would be better than anything else out there with around 400 hp / 400 tq.

 

Drinking the john deere kool-aid? Fendt makes the most fuel efficient tractor out there. I drive JD too, just saying is all.

 

I get 17 city and 20 hwy now with the 5.4...15 city if I'm sitting in traffic idling a lot, like down in Denver.

 

You can't just compare the weight of an F150 to the Flex, there is more to it. The F150 will do most of its on-road driving in full 4x2 mode (even on 4x4 models), the fuel economy will be tested in 4x2 mode - and rightfully so.
The Flex EcoBoost is always driving in AWD. This will eat up any benefit in weight saving. Even though the consumer market has the perception that smaller unibody AWD crossovers get better fuel economy than a body-on-frame with part time 4x4 - doesn't mean it is so. This is why the Durango is so much thirstier than the Tahoe or Expedition, even though it is lighter. Stuck in AWD! And good luck if you want to tow something heavy with a Hemi Durango. Probably drains the tank faster than anything else out there.

 

I find it funny that people who have never driven one and for that matter never even seen one run already have decided the eco boost doesn't belong in a truck and that it can't get the mileage the people designing, testing and building them say it will......

 

Well said, let's see how it does when on the roads.

 

Good post Ryan. I guess the only thing I would offer is that automakers all historically brag about power and fuel economy during development. When the rubber finally meets the road, the real world results are sometimes less than stellar. I hope that Ford has a home run with this and if they put it in the F-150 like I'm fairly sure they will, it's great right out of the box with the power and economy they are touting.

 

Hey guys, I've been off the forum for a while and I'm catching up on some reading, so I'm sorry for jumping in here late. I have an 08 taurus with the 3.5, and my brother has an 09 flex with the 3.5. Both of these vehicles are beating the window sticker for mileage. I get 22/28 and my brother gets 20/26. I have test drove a 2010 SHO, and I can tell you that engine will more than handle what you can through at an F-150. Remember the eco boost puts out more hp and almost as much tq as the 5.4. I do believe that this engine will meet or exceed the estimated fuel mileage based on what I am seeing out of my 3.5.

 

I drove the Ecoboost at Fontana Speedway Saturday, WOW!
Twin turbos mounted right to the exhaust manifolds.
No lag.
Out-dragged a 6.2L on their dragstrip (I drove both)
Drove one pulling a trailer, did just fine.
I'd buy one of these motors.

 

We just bought a 2011 Taurus and love it! Believe it or not we actually beat the sticker estimated MPG. We took it on a trip to FL and averaged 28 - 29 mpg going 70 - 75 the whole way there. The little woman was a truck girl but now she's all about the Taurus!

My hope is that the new EB F-150 will beat the sticker mpg. I'll be ordering a new F-150 later this year or maybe next to replace my 2006 screw depending on the budget.

 

[QUOTE=fordfaninIL.;8316017]Remember the eco boost puts out more hp and almost as much tq as the 5.4.
More torque than the 5.4! The 5.4 put out 390 lb-ft, but only when running on E-85. 365 lb-ft when running on regular unleaded. That's also ignoring the torque curve. The EcoBoost has 420 lb-ft at 2,500 rpm on regular unleaded! With a very flat torque curve! It's amazing, there appears to be no drawbacks for this engine.
