Repair-It

Pretty quick at lower speeds but HP/weight is still a thing as it traps ~87. The description of the quietness and ride quality are pretty impressive. GM's still the only one to use an IFS in their medium duty trucks so they ought to have the best driving manners (and they always have).

765 lb-ft must feel pretty fast. I bet most owners think it does 0-60 at least 2 seconds faster than the article lists

7.2 is pretty good but you can see by the trap speed that aerodynamics start to really limit higher speed acceleration.
