So I did some quick math just to explore the rev band available on the RAM 1500 EcoDiesel.

Max Power= 240 horsepower @ 3,600 RPM (351 lb-ft of torque @ 3,600 RPM)
Max Torque= 420 pounds-feet of torque @ 2,000 RPM (159 HP @ 2,000 RPM)


Keep in mind these numbers do not factor in parasitic driveline loss.

Starting with the Max Torque 420 lb-ft @ 2000 RPM, Power equals:

Power at 2000 RPM: 159 HP

Power at 1800 RPM: 144 HP

Power at 1600 RPM: 128 HP

Power at 1400 RPM: 112 HP

Power at 1200 RPM: 96 HP

Power at 1000 RPM: 80 HP

Now, Max Power 240 HP @ 3,600 RPM, Torque equals:

Torque at 3600 RPM: 351 lb-ft

Torque at 3400 RPM: 371 lb-ft

Torque at 3200 RPM: 394 lb-ft


Keep in mind these are crude calculations, but they are a good look and what you can expect.

Whats wrong with the torque curve? Looks fine to me

That is ass loads of torque...

Keep in mind the 5.7L V8 only has 410lbs of torque. Ram rates the 1500 diesel at 430.

I have no complaints about torque here. The Ram 1500 should be able to do everything I want it to, and it should be able to do it at a pretty good pace.

430 lbs of torque is pretty good in my estimation.

For a lot of people it should be enough, it's not often you see people hauling loads often that push the towing cap to the max.

well torque is what gets you moving so even if your not hauling having all your available torque from low down is a huge boon to fuel efficiency...

seems like between 1800 and 2000 is the sweet spot. lets just hope the transmission is smart enough to know that and keep it there.

the true test of the computer will be under towing. If its smart it will hold the gears longer so when it upshifts it drops back into the 1800-2000 range.

hopefully it does
rather not have some faulty system on board. need to max efficiency and power!
