2021 Cummins 1075 lbft peak torque at 1356 rpm
Apparently the 2021 Cummins makes its peak torque of 1075 lbft at 1356 rpm. Are you still impressed?

Torque charts are nice but just remember that's at full throttle and maximum boost while consuming maximum fuel. Not something you encounter when towing down the highway.
For me what's more important is the torque the engine can make while towing and making the towing the easiest while making the best fuel economy. This is very difficult to quantify except for the fuel economy performance. In my mind the Power Stroke is the leader in this category for the 2020 models and I suspect will continue to lead for the 2021 models.
The true leader is the one that has the lowest operating expenses and downtime after 3-400k miles....and we all know which one that is! ;)
Happy New Year! :B
I know exactly which one that is... :W
Drivetrain is still all factory and running like a jewel. :B

Happy New Year! :B- I have an old 660 foot pounds of torque and have a hard time keeping the tires connected at boat ramps now. I can't imagine trying to get out of the water with double what I have now.

Who really cares if one truck or the other tows up the Ike 12 seconds faster or slower than the other ones. All three are not your grandfather's truck anymore. Buy what turns your crank and enjoy it.
12 seconds isn’t much but I think the 2020 Ram was about a mile behind the 2020 Powerstroke. It might not matter but it kind of put the Powerstroke in a league of its own. I think it would be nice to see the 2021 close the gap a bit.Me Again wrote:

I agree...- Amen I agree with Me Again wholeheartedly!

Your thinking the torque is 1075 lbft from 1356 to 1800 rpm, then drops to 807 lbft by the time the engine hits 2800 rpm .... maybe, I hope your right but I'm not convinced. I wish they would publish torque curves.
Sounds about right. When Cummins went from the 650 Lb Ft to 800 Lb Ft in 2011. Both hit peak torque at 1600 and made the same peak 350 HP at 2800. The 650 torque curve remained flat until peak HP and the 800's torque gradually declined until it made the same peak HP at 2800 RPM.
It's impossible to know exactly what the torque curve would look like when we are only given power or torque at two rpm points. If the article I read is right stating peak torque of 1075 lbft @ 1356 rpm, then we know that point. It is only possible that the torque remains at 1075 for as long as 2100 rpm. Beyond 2100 rpm the torque absolutely drops off but it could just as easily be dropping from 1400,1600,1800 ... who knows, we can only guess. If peak HP is 430 HP @ 2800 rpm then we know the torque at 2800 rpm is 807 lbft. As the engine rpm drops lower and lower form 2100 rpm the less relevant the torque value is as far as describing how the engine will pull a hill. It would be nice if Cummins would rate the engine as making peak torque of 1075 lbft from 1356 to 1600 or 1800 rpm ... or what ever it is.
