TFL just posted this video.For your entertainment. Spoiler alert, Ford lost.Ford 7.3 vs Chevy 6.6Honestly, 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.

Having a one time test is one thing, but having hundreds of people post their tank to tank hand calculated numbers is another.
