I think something worth mentioning is the advantages of the diesel in the Ram 1500 vs the 2500 and 3500 trucks. In the 1500, the main advantage of the diesel is fuel economy, especially since the Ecodiesel upcharge is relatively small in comparison to the HD trucks. The Ecodiesel also provides decent towing performance, although the Hemi will likely perform better in all conditions with the possible exception of very high elevation.
In 2500 and 3500 trucks, the diesel gets better mpg, but since the upcharge is significant, the fuel economy is not the main attraction. The big draw for the HD diesel is vastly improved towing performance with heavy trailers, especially at high elevations.

I have a theory about that. Drivers today don't remember the time when our cars had lower gears, and no overdrive, and we ran pretty high RPM at highway speed. They have never heard a engine run as it was designed. All the RPM they have heard is at the shift point.
There is definitely some truth in this. My roommate in college had a 1977 Buick which had a 3 speed automatic and a 4.11 rear gear. That car would run at over 3000rpm on the highway and we never thought anything about it. He put well over 100K miles on the engine before he sold the car.

I can see how the Hemi has faster 0-60 times than the Ecodiesel because it has higher hp, but I would expect its towing performance to be better. But the test numbers, comments, tow rating, and seat of the pants feel make me question whether it really has 420 ft-lbs of torque. Do those towing tests keep it in gear all the way to redline? I'd like to see real-world tests run at no more than 4000 rpms or so.

So when they hear an engine running, making good power, running free, and clean, making a little noise, (which I love). It scares them. Most are afraid to use what they got, Never heard it work before

Why? Why not run the engine up to where the engine makes it's rated power? People really need to get over their fright of high RPM's..

The problem with modern computer control engines is they can pull power out at any time they want.
These high power hot rod engines have a very low duty cycle. Sure, they make big HP but then they will pull power to keep from melting down.
