My only rebuttal on this graph (which is nice to see BTW...hadn't seen one yet) is that not only does it depict a better/flatter power curve than the other motors (which is fine and probably accurate with the turbo), it also depicts a higher peak number than the 6.2, which I think is in error according to Ford, be it torque or HP. Could the EB tow better because of it's design despite lower peak numbers?? Absolutely. This just makes me doubt the validity of this particular graph, that's all.

 

Well I tow with the truck and it does a fine job. I've also Dyno tuned turbo vehicles I've owned and others and the TQ curve is pretty spot on if you ask me.

The graph was taken from Motortrends review.

"A SuperFlow eddy current dyno was used for testing all trucks. (Eddy current dynos generally show lower numbers than inertia dynos.)"

Also stated:

"Although it is possible to theoretically calculate crank horsepower numbers from wheel horsepower numbers, we're using the wheel horsepower numbers to measure the trucks against each other and not against factory claims."

Torque: As you can see here, the torque curves for all four engines are fairly flat. The EcoBoost has the best of all worlds: flat curve, most torque, and lowest rpm at which peak torque was achieved.

Horsepower: EcoBoost engine had most power on the dynamometer, followed closely by the 6.2L, then the 5.0L, with the 3.7L closing

My complaint with them is the dyno runs were made in second gear and that the axle ratios were different. I don't really put much stock into the actual output range of that graph, however the curve should be pretty accurate.

 

Like I said, not debating the towing capability of that motor not one little bit, but I've got to throw up the BS flag on that sucker having better peak torque and HP than the 6.2. I could be proven wrong though, and I'll take it, but that graph doesn't do it for me...reeks of sales gimmic to push the EB. Let me reiteriate, not downing that motors capabilites or numbers at all, just sheds too much bad light on the 6.2, which I don't have for the record.

 

For the record, I would never depend on MotorTrends articles to inlfuence my buying....

 

because the Super Duty's ecoboost isn't out yet. 5.0 V8 direct injected twin turbo "bobcat"

 

Dyno testing was done by a third party... and nobody here is trying to influence anyone from a magazine article. Just posting numbers.

I own the EB and can say from experience of owning a few trucks that this thing pulls with ease. I don't need dyno numbers to know how the truck handles and pulls a heavy trailer. As mentioned by someone earlier, it doesn't hunt for gears and pulls very smooth. This truck was the number one reason I didn't buy a F250 diesel - Which would of towed great, and is a great truck, but for me personally would of been overkill for my daily usage.

 

really? then why does ford say the f250 6.2 has 385/405 and the f150 has 411/434...
