Wow, I had to click the fact sheet link but it says the eco boost is going to be able to tow 11,300 lbs the same as the 6.2? That seems crazy.

I was looking at upgrading to an F-150 soon but these new engines intrigue me. I'll wait another year to see how they hold up before I look into the year-end closeout deals NEXT year.

That is crazy towing power of the eco boost.

I'm with you Jimmy, I have thought about a new Trac, but I think now I will wait on the F-150 and it's new engine line up. I am anxious to see mpg ratings for the engines. I will be nice to get over 20mpg with 300 to 360 hp. I doubt that the 6.2 will get that but I am excited about the new 5-0, which I would rather have for the V8 sound. Hope they will run on regular gas.

If I'm in a lightweight sports car, an engine that has peak torque numbers smaller than peak horsepower numbers is acceptable. But not for a truck that's used to haul loads.
Obviously it's far more complex than that, but as a general rule of thumb, motors that have larger peak lb.-ft. numbers, and when those numbers occur at lower RPMs, they make more suitable prime movers for heavier vehicles.
A more precise measurement is to find the lowest RPM that the vehicle will keep moving reliably at (typically 1000-1500), and the RPM at peak HP. Take the first integral of the horsepower and/or torque curve(s) between these two limits. This will give a better picture of the motor's ability to move the vehicle throughout it's usable power band. For trucks that you're not going to want to run up to redline every time, modify the high limit to the peak torque RPM.

Real truck users need more torque than HP in typical use but with all the pretend truck drivers (never haul anything more than a new 60" plasma TV) they will look at HP and go gaga and in reality they will never care about torque #s. I think the eco boost in the 150 is a good motor for most people that never haul or tow much weight.
