Seems to me, the RAM did pretty well, hard tellin how they would have stacked up with a 6 speed comparison. They said the 4 speed hurt its 0-60 times and thats about it, but really, the truck overall, by the testers seemed pretty good. I love my MC and how much room it has, and the power is awesome, with TQ right off idle. Maybe the chevy has "more power" but really, for day in and out driving, the Cummins is pretty awesome for mileage and driveabilty. I know it is not a true "test" but when my wife first drove the truck, she realized right away the power that is available even when starting in second gear. I guess it hard to buy the wrong truck, but depending on where your rules for truck buying goes, the Cummins, has way fewer issues than the PSD and the Duramax is a powerful and proven engine, but I always say to guys looking for a new diesel truck, look under the hood, what would you rather work on. They see my point. Scotty
