2015 F150 Engine Specs

A bunch of politicians in DC. It isn't engineers. The bureaucrats make up a number for CAFE (corporate average fuel economy) and the automakers have to meet it. The problem is there are two ways to increase MPG. Make vehicles lighter so you get a death trap on wheels like a smart car, or smaller displacement. The problem is it gets expensive and complicated to get a lot of horsepower out of a smaller engine and still use 87 octane.

Ford strives to be the head of the pack, to make more economical pickup trucks, that are lighter, faster, stronger, more capable.

By 2025 are not the CAFE standards going up to like 53 mpg?
I have not dug into them to much. Is it based off the best engine for each model, or the average of all engines?

Judging where the other ecoboosts have been for hp and torque per liter i'd say the new 2.7L should be 310hp and 350ft*lbs. That will place it just up from the new base 3.5L N.A. and just under the 5.0.
Just my thoughts on the new line up, not sure about the new base 3.5L though. For guessing sake I'll say 290hp and 275ft*lbs.

The peak numbers may be just under the 5.0 but I bet it will out-tow the 5.0 because its peak torque will occur at much lower rpm than the 5.0. The beauty of the Ecoboosts is the difference at low rpm/part throttle. Any engine can be made to perform at WOT and huge rpm. Everyday driveability and towing needs the power down low.
Quote from F-150online.com homepage:
Proven family of engines
In addition to the all-new 2.7-liter EcoBoost, the new F-150 will feature a complete lineup of powerplants to let customers tailor the nation’s best-selling truck to their needs. The 3.5-liter EcoBoost returns, along with an all-new naturally aspirated 3.5-liter V6 and an improved 5.0-liter V8.
The all-new 3.5-liter V6 replaces the current 3.7-liter V6, and uses twin independent variable camshaft timing to provide a flat torque curve and improved efficiency as the highly capable new standard engine in the new F-150. The available 5.0-liter V8 returns with improved cylinder breathing and new mid-lock variable cam timing to improve fuel economy while maintaining its tow-friendly torque.

I don't know why they dropped a larger displacement direct injection 3.7 engine for a NA 3.5.. to me they should have taken the current 3.7, gave the valvetrain the same treatment as the new 3.5, bumped power 10-15hp and called it a day..
I also don't understand the 2.7, I could see if they wanted something between the 3.5 and 2.3 Ecoboosts to put in an Edge, Fusion, or something, but definitely NOT in a pickup where customers have more than enough choices

it's part of their plan to make CAFE standards i spose. We know they have a plan on how to do this. I'd bet 75% of f150s on the road today never have a receiver put into the hitch. The 2.7 would probably treat them just fine.

Heard on one of the interviews done on autoline.tv that their goal is to hit 30mpg. no way that's going to happen with the 6.2 unless you do a lot of fancy tech. with the new stuff developed with the 2.7 I don't see it being much cheaper than the 3.5 EB. right now that's a $1095 option that is suppose to pay off just after 3 years of ownership. My guess is that the new 2.7 is going to be about $795 or $895.
in contrast, the RAM EcoDiesel is a $4000 option, the fuel on average is 15% higher cost (running about .70 higher per gal right now in my area) & has a historically higher cost of maint. & repair. Excluding the higher maint. cost, it's going to take over 12 years to pay off (15k/yr miles, which gives you about a $260/yr savings in fuel vs. the EB).
For Ford (or anyone else) to go Diesel, there's going to have to be a substantial increase in mpg or have a considerable advantage towing or something like that to make the case.

They are using a smaller base motor because of the reduced overall weight of the new truck. Even comparing the current 3.5 displacement V6 found in the Edge, Explorer, Taurus which puts out 285-290 HP depending on application. That's at worst 20 HP down from the 305 HP 3.7. The significant weight reduction will more than make up for such a small decrease in power.
I think people are underestimating how big an impact the weight reduction will have on performance. I did some calculations in another post comparing the 6.2 in the current body to the 5.0 in the 2015:
