Ram 1500 diesel review
First one I've seen, looks like Ram boosted the tq output for bragging rights in the ads....it's now 430 lbs-ft Linky Still not epa rated, but they got 24 mpg in mixed (city and highway) driving...

I did read it again. The 3.0L diesel makes 240 hp, the 5.7L Hemi makes 395 hp. I acknowledge that power doesn't exist across the entire RPM range, but it's just not accurate to say the diesel is the more powerful of the two.
I didn't say the diesel was the most powerful of the two. I said the opposite. Are you sure you aren't the guy who wrote that Chev quiet cab add? Read it again.
I simply don't understand the compulsion to compare these engines at the same RPM. It's like comparing a running back to a wide receiver but never throwing a pass. That's not a deficiency of the wide receiver -- it's a misuse of his abilities. The same is true with running a gas engine at low RPMs when power is needed. Why would you do that?
The entire purpose of the transmission is to put the engine's power to the ground, yet so many people choose to ignore this. A better spreadsheet would be one that shows maximum available power at any given road speed. Do this and you'll find the diesel and gas engines will be running different RPMs (because they'll be using different gears) at the same road speed.
Because you can't run the gas engine at low RPM's and make the same power as the diesel. Below 3500 RPM the diesel will make more power in any gear. That's the point. The diesel makes more power at lower RPM allowing it to pull in higher gears at lower engine speeds more efficiently. True, you don't have the same maximum performance capability but it makes for a more relaxed drive and less shifting. Throw in 30% better fuel efficiency and it becomes pretty appealing to a lot of people.
