If the new Powerstroke is really capable of putting out that kind of power it should be able to maintain the speed limit up the Ike with a 28000 lb trailer in tow. Based on the performance of the Duramax when it pulled against the Freightliner I think these little diesels are not able to produce their rated power over a sustained pull. Maybe it's just the thin air at 10000 feet that prevents them from pulling as they should?

Yeah. If this is sustained power, then it should easily mop the floor with the other two.

Advertisement laws do not require a manufacturer to advertise sustained power numbers. All they have to so is reach a certain power level in a short burst in accordance to SAE procedures which is at low altitudes. Some manufacturers factor in sustained power, and some don't. I wish sustained power numbers was a requirement for the J2807 tow standard meaning you can only advertise the lowest power an engine makes performing the up hill test. I have a feeling that some of the power ratings would drop considerably if it were.
