Ford needs to quit promising mileage with the eb motors. It's making a good motor look worse that it is. While you can get some good mpg if you stay out the boost, most drivers don't understand that. Even with conservative driving, the still seems to be a bit of a difference between similar trucks. My buddy easily gets 18 mpg city in his xlt driving normal while I'm lucky to avg 15 in my FX4. The Mrs can hit 16. In the end, the power is up there with or beyond bigger motors, but the avg mileage isn't any better.

Well that begs the question of what motor the Ecoboost is suppose to get better fuel economy than? The bigger V8s (6.2L and 5.7L) that it meets their capabilities/performance or the smaller V8s (5.0L and 5.3L) that it dominates their capabilities/performance by a considerable margin? The Ecoboost does get better fuel mileage than the other truck engines that meet it's capabilities, but not necessarily the ones that have lesser capabilities and performance which is kind of a no brainer. I mean, you wouldn't expect the 6.2L to get better fuel mileage than the less powerful 5.0L would you? Then why would one be surprised that the Ecoboost would get worse fuel mileage when you need its "more than the 5.0L" power?

I agree with your statement and understand. But when Ford states power of a V-8 with the economy of a V-6, it's selling consumers the hope that they'll get the mileage of let's say a 3.7 F-150 or Ram V-6 with the power of a hemi or 6.2. I'm personally satisfied with my mileage as the truck hits what's advertised. But a lot of magazine articles on the otherhand, slam the eb on it's mileage like they expected it to get 20 MPG city or somerging. That's just not realistic in a half ton gasser.

Keep in mind that when the eb came out, the only v6 that got better mileage was the 3.7 that was released at the same time. Furthermore, it made more power than all but a couple of existing (really inefficient) v8's. To top it all, it made more low end torque than all existing v8's while beating all but one v6 in fuel mileage. I'd say the marketing was pretty accurate.

Funny thing is, it still makes more low end torque than the current most powerful V8 in a half ton engine, the GM 6.2L. Of course the EB will blow away the 6.2L in torque with just a tune as you already know.


Keep in mind that these 420hp/460lb-ft power numbers are on premium fuel per GM. I am unsure what the they are on regular fuel.



And here is the EB compared to the current most fuel efficient V8 in a half ton engine, the GM 5.3L.

I guess what it comes down to is if that much power lost, especially at the lower rpms, is worth the 1 mpg difference. To me, not at all.

I always chuckle when I hear the new GM commercial for their small V8 saying it beats the ford ecoboost in MPG......well of course it does, it is a puss of a motor. Don't come to the table with a less capable motor in a truck and brag it get better fuel economy, it is just silly. I bought the Ecoboost (well, 3 EB F150's now) because of the toruqe, PERIOD, the MPG's were a bonus. And not that the aftermarket culture of the EB is in full force, I am reaping the benefits of a factory forced induction motor

I say the more, the merrier.
Advance/evolution in engine technology and selection can't be anything but good.

the thread started out about the upcoming 2.7L EB. Does anyone know if the 2.7L is still going to be a V6 or could they put in a 4 cylinder to achieve the fuel economy numbers? I would hate to think V4.
