Based on differential gearing it was able to haul more than this Ford was rated because the Chevy was a 3.73 differential gear versus the Ford 3.55. Don't forget that you're using winter gas and running the heater.

Cup & Cone gm is weaker there fore not as much fuel

[@aarons3008]

Also the Chevrolet managed that better mpg despite the fact that they used 85 octane (with 10% ethanol) yet for some reason on the Ford they gave it 87 (without ethanol) even though both manufacturers say 87 minimum. I'd imagine if the Chevrolet had gotten the equal fuel it would have been an even larger margin of difference.

[@EricFortuneJr.]

This channel has always been a wee bit biased towards GM. All these comments talking about fuel economy are quite annoying. A Toyota Prius gets better gas mileage than almost anything. But that’s the only thing it does better.

[@Bmc1025]

I am a diehard GM guy and I agree. I still see the GM doing better MPG but I think it would have been close enough it wouldn't be a selling point.

[@APGJuggernaut]

I do agree that the constant fuel mileage comments can get annoying, especially from private owners that should be fully aware of the cost to operate a full size truck. But given that the 7.3 is intended to be a reliable and economical motor for commercial and fleet operators, grading it heavily on its fuel economy is warranted. I don't think the ratings were terrible given the testing conditions and elevation. But I was expecting it to get a little closer to the Chevys numbers.

[@APGJuggernaut]

@@Bmc1025 Tow rating, at least to me, seem to vary a lot truck to truck even within the same models. I'll say this much, its getting better mileage than the Ecoboost F-150 I used to own. Loved that truck and the power as much as it loved gas

[@1134EMP]

Not bad, 20 years ago, I used to have a 97 4x4 f250 with the 7.5L, a 5 speed manual and 3.55 gears. Best mpg I ever got was 13.5. This was with 285/75r16 tires. Most of the time 11-12mpg. That engine was rated 245hp and 410tq. So now we get more power and better economy.

Si Raff I bought the truck new,and was going on the Toyota reliability. And that has proved true. If I had to buy a new truck it would probably be a Toyota. I worked at a local Chevy dealer until just recently, and saw a lot of issues with the new Chevy’s. The more bells and whistles, the more problems.

[@shaunbeach9502]

A 2019 tundra probably won't be able to get any better gas mileage either.

[@davidhorne2326]

Shaun Beach that’s true. Toyota needs to get the mpg’s up.

[@marvinsauer8493]

It is pretty tough to split mpg tests over several days. Each leg of tests, on both trucks, should be done under near identical ambient conditions, meaning that each leg should be performed at nearly same time on same day. Temperature, atmospheric pressure, humidity, wind and fuel mix all play a role.

[@dennyhall69]

Thank you, glad I am not the only one that seen that. It is harder for a large truck to push through cold air. I noticed that they was bundled up when testing the f250

[@JHuffPhoto]

Interesting result. The result is consistent with what I would expect. Chevy does a very good job of squeezing efficiency out of their vehicles. However, I would not let a relatively small (really within the margin of error) difference in fuel economy be the deciding factor between these two trucks. There are many other considerations in my opinion. Either vehicle would be a good choice and I think that personal preference in styling and design will likely be big factors in peoples purchasing choices.

I have always said it, ford’s numbers on paper are always the best, but in real world everything changes

Do you realize that they did that to get an "out-of-the gate" number, right? People are going to be modifying the heck out of these monsters anyway. I am rare, I love Ford and Chevy and I feel like they make each other greater. I am more of a Ford dude, but I am impressed with RAM's 6.4 HEMI as well. What a trio, 6.4, 6.6, 7.3 like the good old days of big power.

[@JsGarage]

Christopher Williams 6.4 Hemi is much more appealing with its new 8 speed. The old 66RFE held it back quite a bit not even having a true 6 speed ratio spread.

[@acdii]

They tested the Tremor on the Dyno, not a good choice for a true dyno test. They would have been better off testing the one in this video on the dyno. The 10 speed is better suited to the 3.55 gearing than the 4.10 or whatever it was on the Tremor. When you look at the dyno on the 6.7 with the 10 speed and 3.55 gears the numbers were off the chart.

What concerns me is longevity on these 8 and 10 speeds, they do a lot more shifting especially pulling or driving in the hills. Maybe I'm wrong but my basic knowledge on transmissions make me thing more shifting= more wear and potentially more heat?

[@workct4102]

I have not noticed that. From a 4spd to a 10 spd, 5.4 to a 3.5 EB, the newer truck does stay in 8th most of my towing trips, but the power difference in the engines allows it to stay put, where the 5.4 would kick to 3rd and rev to 4k. Haven't needed the 3.5 up that high yet.

Depending upon the wind - that can really kill mileage. My F350 with a camper averages 12.3 with no wind. On a windy day the mileage can go as low as 9.5 MPG. You need to re-run the test on a day with no wind if you can do that.

[@frankd.3985]

Air temperature also makes quite a bit of difference in MPG comparisons. I used to have a Ford extended E-350 with a V-10. In cold weather (20 degrees F) it'd get about 13 MPG with about 3500# of cargo. In 70 degree weather, it'd be up to 16 MPG. If your comparing MPG you have to keep the conditions the same as possible. Also the MPG with a gas engine may be lower, but cost of maintenance and intital cost compared to a diesel is also lower. I've got a diesel that I pull my 5th wheel camper with and I love it, but I don't think you ever get you money back. Thank you for all of your great tests.

[@gjolinares23]

If you did that’s amazing. Those numbers sound quite a bit over shot though. Are you sure you did the math right? The V-10s were said to be around 10mpg empty and drop when hauling weren’t they?

You can't compare tests from different times of year. You need to take into account winter fuel and summer fuel blends. Also air temperature will affect fuel milage. To compare they need to be tested at the same time under the same conditions with the same fuel.

Agreed. A truer test would have been them running side by side at the same time, pulling the same weight(GCVW), and then compare. Considering both test runs of the F250 were into the wind accounts for something as well as the winter blend fuel.

I live in a harsh winter climate 5 months out of the year in the Upper Peninsula of Michigan. Mechanical door steps, multi use tailgates, auto tailgates, low profile wheels, fancy chrome trim, and lady features! All that stuff fails at -10 and in deep snow with a 100 Libs of ice stuck to the truck. Ford has tons of great tech! Dodge plenty of power with a Yugo transmission! And the Chevy with a check engine light. I got 240,000 on my 02 Chevy Avalanche and it lasted 17 years before I sold it. I bought a 14 Chevy WT 1500 with 100,000 and it works great.

I think that's one of the biggest problems in their test, they do it at speed. Most people pulling that heavy of a load in a gas (hell even in a diesel) would be 60-65mph for safety and control of the load. Also the Chevy was done in summer and lite winds, the poor Ford got winter fuel (packed with additives and maxed on Ethanol) and high winds. I can tell you all about how high winds effects MPG, I live on the South Texas Coast. We see 20mph + winds very regularly, my 2010 Tundra unloaded driving into that high wind will make 8-9mpg @60mph and 5-6mpg @75mph. But if we get a very calm day of wind, I get 20.8mpg @60mph and 16-17mpg @75mph. Best I have very got was 24.276mpg @60mph with at least a 25mph wind at my back on a trip up to San Antonio. My combined over the 2 years I've had the truck is 13.295mpg, that's about a 35% highway and 65% city driving. Right now on winter blend I'm pulling 10.8-11.9mpg in the city around here, in summer months I get 12.7-14mpg in the city (summer fuel here has almost no ethanol at all, too hot for it to stay in the tanks). So fuel is a big play just as wind is.
