I found the output specs on the new Cummings:

§ Cummins 6.7L Turbo Diesel I-6
[*]350 horsepower at 3,000 rpm[*]650 lb-ft of torque at 1,500 rpm (automatic)[*]610 lb-ft of torque at 1,400 rpm (manual) [/ul]
Why is the torque on the manual lower than the automatic? I always thought a manual would outpull an automatic transmission.

 

good question, i don't know how the same engine can have different torque ratings with different tranny's. thought the numbers they give are off the crank.

 

for starters it could be the clutch. being able to handle the power output and keep longevity it might have been too "grabby" for most people. however the difference is only 40 ft-lb and 100rpm. with the way the torque curve is on diesels I wonder what the torque would be on the manual at say, 1500, or the auto at 1400.

I bet it is all a numbers game to try and get the public to buy the auto because it has OOOoooh, 40 more ft-lb of torque. any good performance box will plus that up easy on the lowest setting.

 

Drew's probably right about that 40 lb ft of torque aint much at all and in 100 rpm's I could see the manual making that.the only thing that I really wanna see is the new power wagon with diesel option. Hot dang is that gnna be sick
