The 2019 GMC 3500 C&C Dmax is rated at 445 hp/910 lb-ft just like the pick up version. Not sure how they were able to do this with the different emissions certifications, but they are the same output.
Its simple... Advertised hp and torque is understated in the pick up version.
Also I don't think the GM was defueling either since during initial take off the truck seamed a bit lethargic from what I could tell, but one could say the same about the Freightliner.
The GM was not putting out anywhere near its advertised HP. A truck equipped with an engine making 445 hp / 910 lb ft would have been able to make that run in very close to 7 minutes 20 seconds. I think the high altitude must drastically affect the power these engines are able to make. If the Cummins was producing the power it is advertised to make it should have made the run in just over 9 minutes.
