I have a 2016 2500 Cummins that I use for work. Great truck, very torquey and gets good mileage. I sold my 2015 Denali duramax to try the new super duty out. Despite what a lot of the haters say there really isn't a bad truck out there. My 2016 Cummins and 2015 duramax that I just sold are both outstanding trucks. I'm excited to get some miles on my 2017 super duty to see how I like it.

For the life of me, I just cannot figure out why people continue to insist that a straight-6 Cummins is supposed to run like a V8 PSD or Duramax.

The straight 6 is very capable of producing some real power. The inline design allows for a nice long power stoke that really produces some nice torque on the low end and it does allow for fewer moving parts than the "V" formation. Some say that a diesel should always be an inline design. I don't subscribe to that ideology myself but to many its Gospel truth.

im not familiar with ram previous to '14 and maybe that's what your referring to ? on the newest ram I think you would be hard pressed to find any component that wasn't as heavy duty as other trucks on the market. if we based it on looks, the sterling 10.5 looks tiny compared to the 11.5aam that ram uses. just sayin


luckily now we have sophisticated computers that can design lighter and smaller components that are just as strong. so a smaller steering arm may appear like a 'car part' to the untrained eye

The Cummins ISX15 14.9L Straight 6 in class 8 trucks can make 600 HP and 2050# ft-lbs of torque. I don't think the # of cylinders or straight configuration is the limit.

That said, if you drive the Ram's 6.7 Cummins HO 385/900 and a Ford 440/860 or 440/925 back to back, the Ford feels MUCH quicker. I was really surprised how sluggish the Ram HO (w/ the Aisin trans) felt.

I ​​understand what you're saying, but Cummins vs the PSD or Duramax is not an apples to apples comparison, regardless of what the numbers say. Yet folks continue to do that comparison, and then think the Cummins is some how deficit because it is "not as fast". The Cummins is designed to pull, not win any races up the Ike Gauntlet. HP and TQ are not measures of speed or quickness. But people keep believing the marketing as if we're something meaningful, and then make decisions based on less than all the facts.

The I6 is very capable of speed and power when not limited by the transmission and detuning. I have a friend who built and drag races a Dodge with a 5.9. It makes over 800 hp. and over 1500 ft/lbs. of torque. It regularly beats Camaro's and Mustangs on the drag strip and has been featured in three Diesel Truck Magazines. A very impressive truck indeed.


Oh, I have to mention that three years ago this friend went to by a new truck (and he's a Dodge Man). As a truck builder he did extensive research and test drove them all. He ended up buying a 2014 Ford F250. He loves the Scorpion engine, and will be the first to tell you that after decades of driving a Dodge diesel that the Ford is a better truck in almost every way. He has taken some heat from his Dodge buddies but, hasn't regretted his purchase. I'm not trying to put down Ram or Dodge. This is a true story.

Wrong, the 2004 Cummins was a beast, fast off the line, fast rolling, no dead pedal, and pulled like a team of mules. 2015 Cummins is a gutless dog, big time dead pedal, slow off the line, slow rolling, slow floored, its a joke how pathetic it performs. Ram has obviously neutered the thing.

One has to wonder if Ram hasn't done this to the Cummins so that the Fiat engine will be better received when/if they utilize it.

600HP proves the point that it is hard to make HP from the inline 6 diesel. Long stroke makes torque. It might pull great, but the V8 diesels are faster. People like faster.

​​​The 2015 is gutless because it isn't fast? Seems you're still comparing apples and oranges. My 2004 Cummins (with 4.10 gears!) was a beast and it did pull great, but it still didn't win any races. It also wasn't drive by wire and had just over half the torque of the current Cummins. The 15 is torque managed, and by most accounts, overly so. But it's no stretch to understand this is done to protect the tranny. This doesn't mean the Cummins cannot be fast, it's just that, all things being equal, the Cummins won't compete well speed-wise against the V8s.

Sorry for the derail, OP. All three are great trucks. Just prioritize your needs and then buy the truck that meets those needs.

I have an 04 Cummins and an 03 F150. The Cummins is used for towing the boat and long trips as I have averaged 26.4 mpg on the highway. The F150 is a smoother ride however I can only get 16 mpg on the highway and I don't have a cap on it like the Dodge has. My next truck will be a Ram 3500 with an 8' bed and cap.

You won't get that same mileage on a new truck, Cummins or not.

Are you getting 26.4 on the highway while towing?
