Ram Goes to Stunning 900 lb-ft of torque

Actually straight sixes have always made their torque at low rpm, just like big block gas motors. It's been proven over the years.

My V8 6.0 PSD was definitely faster off the line with the same GCW than my I6 6.7 CTD. Where my PSD would start to plateau, the CTD continues to pull (kind of like the tortoise and the hare over a longer distance). The shorter stroke of the PSD let the RPM's spin up faster but it also made power at higher revs than the CTD.

Some good info on why the Ram won't necessarily be the fastest, even if it has the most torque. To me being marginally faster up a hill, largely due to simply starting out a little quicker, is pretty meaningless. When I bought my Ram I knew I wasn't getting the fastest diesel. I'm pretty sure I got the best diesel and overall package of the current crop, though - for my needs anyway. None of them are bad by any means.

Everyone knows that a in-line engine makes tons of torque down low and thru the mid rpm range and a V8 is just the opposite so the V8 should be able to out run the Ram over a long haul. Then add the Ram can out tow both the others and the question becomes do you want top speed or towing ability. Just like the Ford EB and the Ram ED do you want top speed or mileage? The Ram is the fastest off the line in every video I have seen also. It was not far enough behind the other two to really make a big difference, it will catch you guys on the backside and control that speed much better than the other two going down the hill.

As far as the lying about the SAE J2807 specs both GM/Chevy and Ford had to remove parts and not just on the F-450 but all across the line up, to be able to get their trucks to look half way decent, Ram did not!

Myself, I think Ram shot themselves in the foot letting that V8 Cummins go. If I were in charge that engine would be in the 1500 and 2500 Ram along with a HD tow/payload option (think 6 lug axles) on the 1500 trucks. I also would have optioned the Ecodiesel in the 1500 but without the HD option. But I'm just a lowly Toolmaker stuck in the Tool & Gage department without any say in the matter.

If cummins had thought a V8 was the way to go they would not have dropped the old VT903 in the old days and kept the inline's. You have a lot of false statements posted here but I am not interested in the BS games of power here. Lots of good trucks built today.

False! I am starting to not take you seriously on how much false information you have posted in this thread. There are many characteristics of an engine that determines when it gets its power, but the cylinder configuration is NOT one of them. The stroke length of the engine has a lot more to do with when an engine gets its torque. There are a lot more dynamics in an engines design that effect its characteristics as well. Currently all three light heavy duty diesel engines get their peak torque at around 1,600 rpm. The only odd man out its the Cummins high output variant that gets its peak torque at a higher 1,700 rpm.

False! Not the F150.



As far as the 2.7L EB versus the Ecodiesel, the mpg may be different but the cost per mile may not be too far off depending on the time of year due to the cost difference in fuels. Also the 2.7L was not "racing" up the hill since it was just doing the speed limit and had plenty of power to accelerate if needed. Just because the Ecodiesel could not hold the speed limit and the Ecoboost could does not mean it was "racing" up the hill. The quicker (not faster) off the line acceleration of the Ecodiesel has a lot more to do with the muck lower first gear of the 8 speed in the Ram than it had to do with engine power.

The differences between the two just depends on preferences. If you like having power to spare in those cases when you need to pass traffic that is going slower than the speed limit and do not mind paying extra in fuel then the 2.7L Ecoboost is for you. If you want better fuel economy, but do not mind not having as much power or you do not mind going slower than the speed limit then the Ecodiesel is for you.

My preferences is that I don't mind paying more for power and capabilities. I have been in one of those situations towing where I was stuck behind slower moving traffic back when I had my 4.6L. I could not pass because I did not have enough power to pass without needing two miles of roadway to do so since the truck was barely able to accelerate. The semi in front of me and I were being passed by trucks that had more power than mine and I was stuck behind that truck for at least 20 miles. After that I said never again which is why my trucks have always been overpowered since then, and I will gladly pay extra for it. Others may not feel the same.

Speaking on passing performance what's the HP rating going to be?

Who gets to the top first is kind of the point isn't of all that power? I mean on one hand you are bragging that your truck OEM has a pickup that makes 900 foot pounds but on the other hand you don't care when you makes it to the top of hill, that seems contradictory to me. Why then feed all that power? Why offer a pickup that specs so great, but gets owned by trucks with considerably less impressive spec sheets. Kinda like the 6.4 gas, stomps the competition in every measurable stat except pulling a load up a hill. Suddenly then it becomes less important how fast you can get up hill, cause you know, it isn't race.

.........and maybe for most of us that use the diesel to tow getting to the top first is not that important. As you said it is not a race. But having the power, even if some is always in reserve, is beneficial and should it be needed, it is there. Nice to know that should the bridge call down to the engine room for more power it will happen. Race of not, the power is nice even if 'just in case' it is needed. And to race the big three diesels against each other might be fun to read about but reality says all three will get to the top of the hill within a matter of seconds of each other so who towing an RV really cares? Also, who cares if the numbers are paper or real world, all three diesel perform so much better than anything in a pickup twenty years ago. It will be interesting to see what we can tow with in another twenty years.

This is based on what towing event?

Almost all of the towing tests I have seen the Ram came in last.

Myself, I think Ram shot themselves in the foot letting that V8 Cummins go. If I were in charge that engine would be in the 1500 and 2500 Ram along with a HD tow/payload option (think 6 lug axles) on the 1500 trucks.

Yeah Ram screwed the pooch by letting go of the 5 liter.
But wow, 900 ft lbs stock is pretty impressive. I guess since the epa put all the programmer guys in the soup line, the OEs are picking up some of the slack.
Love it!
