I went back and watched the 4:00 minute mark of that video. I wonder why the gauge reads up to 240 reverse horsepower a while then drops off to 0? It almost seems as though the gauge starts reading at about 37 mph and it pulls it down to 35 mph then quits displaying. Could it be that while the gauge is displaying a number the wheel brakes are being applied.

240 reverse HP would definitely be slowing the truck. 175 reverse HP at the crankshaft should be enough to hold speed on the steepest part of the hill.


At the 4:00 mark, there is a red light on just over the "D". It goes out just before the -hp drops off to zero At the 6:01 mark it also shows -240 hp of braking, but no red light over the "D". Could the red light mean service brakes are applied?

So to summarize:

Brake Applications:
Ram: 0 (Auto Brake assisted-unproven theory by Ford fanboys)
Ford: 5
GMC: 9

Time:
Ford: 10:20
Ram: 11:32
GMC: 11:47

MPG:
Ram: 2.5 mpg
Ford: 2.4 mpg
GMC: 2.4 mpg



There, I fixed it for you.

I would still love to see how these trucks do at 80F or even 100F.


I agree with testing at 80F or 100F but I doubt the order of performance would change.

And now your ok with reporting the computer mpg when you have always reported major errors with these systems.

TFL reported the brakes were part of the braking system so if you don't like that or agree with it go debate it with them like you do the Australian.



I feel the result will be similar to last years test if it were 80F. I don't


I have stated before that I don't think the computer is accurate with a lot of stop/starts of the engine. The more start/stops are in the tank average, the more it is off based on my experiences. I have also said it is fairly accurate going from point A to B without turning off the engine.

I like to report all the data(good or bad) and let the people decide for themselves instead of only giving them part of the information because of some bias. Mr Truck has reported many inconstancies before and I doubt this would be the last. After all, he also stated the truck/trailer's brake lights were on and yet they were not. Unproven theory by a Ram fanboy


Just as a reminder that the previous 2020 Ram and GM trucks Ike pull had 2 brake applications with less weight. With 30k lbs the GM had more brake applications but the Ram had less.

Give me a brake... [emoticon]


Yeah, because they did not have it on auto like I have been saying for the past two years. Auto works better if the truck is doing the shifting. Full mode is best used if you are shifting manually which they do not do.

I think the Powerstroke will get heat soaked at 80F and would have to cut power just like it looked like it did last year.

Also,it is not an unproven theory that they the brake lights were not one. It shows it in the video when they were behind the truck. And it is not a theory that Mr truck has been wrong before.


I thought the Ram was set to automatic and the cruise control wasn't set on so the system would not apply the brakes.

The Ford wasn't heat soaked as it wasn't pulling as strong from the get go. From what I've been reading this new 2020 pulls really strong compared to the '19.

If Mr. Truck was wrong the chaser truck had plenty of opportunities to see if the brake lights were not on and they could have simply edited Mr. Truck's comment out if he was wrong. There was only very short clips of the chaser truck behind the Ram. So no I don't agree with your theory.

With the Ford the brake lights only come while the wheel brakes are applied. The Ram is probably the same.

That red light is a reflection of of the speedometer needle.

GrassHopper, they did NOT have cruise control set on the last test you mention. For years I have said how **** well my EB brake works when the Cruize is set, now yalol know whatz I'm talkin aboot!

I repeat i have decelerated down miles of 14% locked in second at 33k combined holding 35mph. I would say they have improved keeping the truck at the selected speed. to do what I did I was holding cruise at 30mph or so.

My gauge goes up to 230 braking HP.

I guarantee the EB did not turn off, it simply restricted more or less as needed.

Someone please tell me where the engine was turning 3,500RPM descending the grade???

The "SOUND" of that truck is EXACTLY what mine sounds like coming down a steep grade WITH the EB on. That is NOT just the engine, the fact is when descending grade without the EB on the engine is very quiet in comparison. That was the EB "RUMBLE".

Next time I tow I will experiment with cruise and "AUTO" as I have always used "FULL" EB.

FWIW, I have always used the CC with the EB on my 2011 Chevrolet.

It works so well, I have never tried it the way they do the tests.... Obviously I am not towing 30K....More like 28-30K gross.

I "think" that they do the tests the way they as a throwback to the days when the EBs and CCs were not integreated... I "think" that is pretty much standard across the brands now?

In my owners manual it states that the brake lights come on when the exhaust brake is active letting other drivers know that you are slowing down.
