Let's cut the bull and admit that the ecoboost torture testing is mostly a very effective marketing campaign. You could do the same testing on a 2009-2010 5.4 engine and it would do just as well outside of fuel economy. I'm much more interested in the day to day reliability and cost of ownership of the new engine. The historical weaknesses in the 5.4 would not be have been revealed by towing for 24 hours straight or other such nonsense.

yeah those tests are bull**** if you ask me

That video says: ...."11,300 pounds attached to the back of the F-150".....

The video also claims 24 hours at a high rate of speed. Who knows "how high" that rate of speed was ?

IMO, it doesn't take alot of power to maintain speed with 11.300 lbs on a fairly flat race track.

Now.........drive for 24 hours straight up and down hills at 65 mph with 11.300 lbs and you have my attention !!

the point they are trying to make with the videos is that motor will be reliable and last a long time, sure the 5.4 could probably do that stuff too but the 5.4 is a tried and true design. ford knows there are going to be the usual nay sayers about the reliability of a small displacement twin turbo motor in a big truck and the point of the videos is to prove that it will be a reliable and strong motor as well as being able to out perform the previous motors as well as the competitions motors. of coarse its marketing, thats how they sell trucks but its genius marketing and it showcases the time, money and development that ford has sunk into that motor.


if you watch the video they say it AVERAGED 80 MPH over the coarse of 24 hours. i would like to see any of our 5.4's average 80 MPH for that long pulling 11,300 pounds without throwing a rod

Thanks kozal01 for pointing that out.

What is pretty crazy to me is that the turbos on those engines can handle the 80mph average at over 1000 degrees for so long.

I agree it's a very effective campaign.



I really don't think a steady state speed is testing the limits of the turbos that much. Stop and go trailer towing is much more demanding than cruising at 80 all day long.

i disagree, full throttle averaging 80 MPH is one hell of a test for a turbo, is has no chance to cool and is running near full spool the entire time. cruising 80 MPH without a load is one thing, 80 MPH average pulling max load isnt exactly cruising, the motor is near redline for most of it.

for those that havent seen the track video

I just watched the video above and as far as I can see it never even shows the tachometer so I'm not sure how you can conclude that it was near redline the whole time. My 5.4 is nowhere near redline towing at 80 MPH on a perfectly level road. I'm not saying that it isn't a good example of a properly functioning engine but you could probably buy any recent model V8 Ford on Craigslist and do the exact same test with good results.

the thing you are missing is that they AVERAGED 80 MPH, 82 to be exact meaning in order for them to average that kind of speed over 24 hours including fuel stops and tire changes they would have had to have traveled at a much higher rate more than a few times to reach the 82 MPH average. they said right in the video that they ran it at full throttle for the entire test. i know in my truck full throttle over 70 MPH means my truck is running at redline or pretty damn close. also i dont think anyone is debating that other motors could do that for 24 hours but the point is that Ford is showcasing the durability and ability of that particular motor to hush the people that think that kind of motor wont be durable or reliable enough to put in a truck, thats the point to the entire video series. plus the motor had almost 160,000 miles on it during that test. go back and watch the video again, you may have missed a few things the first time.
