I believe the difference in the exhaust brake performance is Mr. Truck manually down shifted the truck whereas in the past test they let the truck decide when to shift.
I agree with Patriotgrunt that they should be consistent with the test methodology.
No, as I stated before in another thread(which you were apart of) Mr. Truck did not use the correct mode the last time they did an Ike test with the Ram 3500. Nor did the guys in the GM test. He should have used the exhaust brake in "Auto" mode if he wanted the truck to do all the work of downshifting to keep a certain speed. It clearly states in the owners manual that "Auto" mode is used for keeping a certain speed.
The GM trucks are put in their "Auto" mode by selecting cruise control which Mr. Truck used the cruise control in the last GM test going down the hill. So he used the GM in "Auto" mode, but not the Ram in "Auto" mode which is why he had hit the brakes more with the Ram.
"Auto" mode in the Ram is if you want the truck to do all the work(which is what the Ike was all about), and "Full" mode is used if you want to manually control the downshifting to keep a certain speed.
The main different between Ram's "Auto" mode and GM's "Auto" mode is that you don't have to be in cruise control to have it activated. It will keep the speed you were at when let your foot off the accelerator. So if you don't have it cruise control and let off the accelerator at 60 mph at the top of a hill, the truck will automatically put on the exhaust brake and even downshift to keep you at 60 mph since that was the last speed you were at before you let off the accelerator. You have to be in cruise control in order for the GM to do this.
So if you wanted to be fair and consistent between trucks like you are saying, then they need to put the Ram in "Auto" mode since the GM was in its "Auto" mode when they activated cruise control.
I agree with what you said... I'm sure Mr. Truck is not aware of how the different exhaust brake modes work, but he should so the tests are done with the correct settings.
