How's that relevant here? They're not installing HC engines in 25 Ram 1500's, they can't meet CAFE requirements with a NA 5.7.
We're comparing engines in the 1500. I said its pretty said that Ram never put the 6.4 into the 1500, the 6.4 is the "competitor" to the HO and by all accounts it's still the stronger engine and gets better MPG (they compared the 6.4 to the hurricane in the Grand Wagoneer a while ago).
Then I said it's pathetic that a new engine can't beat the 6.4, only in emissions does the Hurricane do better. For guys who want a great experience, the hemi is still the better option.
So then you said "well remember the 3.0 is down 2 cylinders" as if that is some excuse, it's not, the 6.4 is N/A and the hemi when using forced induction puts out more power than any other production engine from the factory.
We all know CAFE is troublesome, but we're talking minuscule differences here. The second you start dipping into the throttle you're going to get worse MPG. Only reason the hurricane appears to get better scores is because of how these engines are tested on the bench but start working them hard like towing or whatever and you'll quickly see why us N/A fans aren't letting go of our v8's.
