That's the first I've heard of TM on a 6.4L Hemi, got a link to a source? I'm not challenging you, just curious as I plan to buy another.
In any case, I think we can agree a diesel is a better choice when "how it performs when towing a heavy load" is the only parameter you measure the trucks' worthiness by. When you add in initial cost, short commuting driving, winter cabin heat in extreme cold, maintenance cost, payload, and a few other parameters, it's not so black and white.
I don't have OEM proof at this point, but safe to say every modern car has torque management. Maybe not necessarily de-rating the peak torque output like the diesels, but they'll delay torque ramp-up off the line.
Even assuming the 6.4 can put 100% of its torque off the line, the Cummins would have to be de-rated to 400 lb-ft to be as weak. And I highly doubt that! So that aside, can you think of any other reason Ram would lower the 6.4 towing capacity that much?
And just so you know, I'm a huge proponent of modern gas powertrains, ever since the 2007 diesel emissions nightmares. I've read nearly every one of your past towing experiences with the 6.4, and even stole your photos to prove to other the coil springs can handle pin weight just as well as leafs.
But I'm making one exception this time because I truly believe gas engines can match a diesel's off the line startability.
Since the point of torque management is to save the drivetrain, wouldn’t the diesel have to be limited to the same as the gas is limited to (not counting the Aisin), at least at startup?
