I also think the rate at which the fuel is delivered to the various engines, as controlled by the fuel management software, must play a huge role in the 0-60 times. My 03 Duramax, with a high performance tune downloaded, takes off from a brake assisted launch like a bat out of hell.....smoke rolling off the wheels and a bit of black smoke rolling out the exhaust as the truck fish tails all over the road, yet there is no way it would pull a 30,000 lb trailer up a hill the way the new Cummins does.
I agree. The 0-60 stat is interesting on these big, heavy, powerful trucks. But I would not use it as one of the criteria for purchase. That is, if the intended purpose is to haul and pull stuff. But it is a very good indication how these vehicles will behave in a stop and go environment.
