Ike Gauntlet 2017 3500s DRW 22,800# load

3 GREAT truck all within a hair of each other + 1 specific test on 1 day = 5 Years of pointless internet forum bragging and boasting.

Anyone who concludes anything other than these are 3 great trucks on very equal footing needs to stop looking through the prism of their favorite brand.

No, defueling a diesel does not give you less fuel economy. It will give you less power from the engine. Well, technically you will use more fuel because it takes you longer to get up a hill versus having full power, but seeing that all of these trucks were about the same time, it wouldn't have been noticeable in this test.

Most modern diesels are programmed to defuel if certain parameters are over their limits like EGTs or boost pressure. Another form of defueling is torque management where you do not get full engine power in the first few gears because the ECM programs it to inject less fuel until you get into the higher gears.

I haven't seen this mentioned yet, but since the Chevy and Ford are very close power wise, and the results reflect that, maybe the Ram was just a very good performing truck which really surprised everyone?

Or perhaps received a non advertised power bump. Mr truck did say the exhaust brake did improve from last year.

I seriously doubt the Ford defueled as it would have been clearly noticeable, but it is possible it was in regen.

There is no noticeable sign of defueling besides less power since the only thing that happens is the injectors inject less fuel. The driver of the truck might notice it depending on the how much the truck is defueling or his experience with the truck, but you would not notice it just by watching a video.

I'm not surprised of your theory... but the truck had ~4k miles on it so it's been thru a few regens.

I wasn't trying to be a smart a$$.......

Sorry you took it that way.

"What most people dont understand is that the two V8's in this test have higher hp ratings that the mighty I6 but they get those numbers through RPM"


Lets take a look at the spes.

Ram 6.7 385 hp @ 2800 rpm
900 ft/lbs @ 1700 rpm

Ford 6.7 440 hp @ 2800 rpm
925 ft/lbs @ 1800 rpm

Duramax 445 hp @2800 rpm
910 ft/lbs @1600 rpm.

If anything I would say the Duramax is able to make the most power across the rpm range with lower rpms than the Ram or Ford.

Interesting all three make the max hp at the same rpm.


"The truck with the flattest power curve and most torque did the poorest..... this really doesn't make sense."

I believe even though not popular belief the Duramax has the flattest power curve of the three.

Ouch, I was just going to bring this up.............but you beat me to it. :B

One things for sure; according to this test, the Dmax puts down the most HP to the ground of the other two.

After owning two trucks with AAM rear axles, I'd take the 15 second penalty and enjoy the ride.

Rebuilding the rear end is pocket change compared to dealing with a CP4 HPFP that has grenaded! :)
