TFL just posted this video.

For your entertainment. Spoiler alert, Ford lost.

Ford 7.3 vs Chevy 6.6

Honestly, I consider the test to be invalid and don't know why they bothered to post it. Apparently the trucks were tested on different days and even TFL commented about the wind. At the turn around point the Ford was getting 7.3mpg but after driving back into the wind the mileage had dropped down around 5mpg. Driving into the wind does far more damage to fuel economy than the gain you get from driving with the wind. The trucks need to be tested under similar conditions or they are wasting everyone's time.

I concede that I do prefer Fords but this comparison was ridiculous.

I think when Ford said that the 7.3L was more efficient, they meant versus the the 6.8L V-10 this engine replaced and not the smaller 6.2L.

They also mention in the video something about the trailer weight not being the same for each truck's test.

I would like to see it tested against all of the gas engines in the class including the 6.2 Ford and Ram's 2500 gasser.

I am waiting to see real world results on Fuelly. Having a one time test is one thing, but having hundreds of people post their tank to tank hand calculated numbers is another.

I think it was said the GM truck had more weight so again hard to be perfect.

Yikes, it sounds like it is a decent performer but that is pretty dismal fuel economy....[emoticon]

I've always found it amusing they use only 66 miles to figure a mpg number....and they let the trucks computer do the shifting on long climbs.

I realize many pickup owners today have no idea what gear the engine needs to be in going up or down steep grades...sooo they let the computer do the shifting for them.

The mpg test with the 6.6 and 7.3 gazzers IMO would be more accurate running 3 tanks and then take a average on the same day with the same trailer over the same highways.

I'm a big GM fan but I would say the Ford front end looks a hellz of a lot better. Good gawdz that GM trucks front is ugly.

The Chevy was running non winter blend gas and probably with less winds and a heavier trailer.

The Ford was running a winter blend gas with probably higher winds and a lighter trailer.

The two samples were run so far apart in time/season, external temps, wind variation, different trailer/weight and with this many different variables this really isn't a good comparison. About the only take away is how the trucks performed pulling x amount of weight.
