Get the real cummins not the eco

Have you owned either one of these engines?

Well, truth to all that has been said. Me, I'm waiting. Hope not to die of old age, but waiting for the 25/ 3500 series to come out with an 8 speed trans behind the 6.4 hemi. My guess, if that ever happens, the diesel will be a hard sell and that's even for those of us that tow heavy. The 8 speeds have an awesome gear ratio all along the band. Again, "I'm waiting". My 2500 Ram would be traded in a second if they ever do. Just my thoughts. lol

Thanks, I'm excited and hoping for a boy. Of course

Yes, definitely congrats on the good news!

I'm sure you'll find what you want - it's a bit tougher with a deadline but truth be told, these are great trucks any way you slice it.

Hopefully it's part of the redesign in 2018 HD major update.

Ford & Chevy will be bringing 10-speed trannies to the light duty fight here shortly; hopefully Ram will answer in 2017 from a light duty perspective.

People who tow a lot still will buy it for fuel savings and ease of towing. You need to spin the hemi's up so high to make power they suck fuel and it makes it feel like the engine is straining. A diesel just chugs along at 1500 rpms and is happy to do so even going up hills vs the 6.4 that needs to spin to 2500 + rpms to get going.

 

[KarL45]

Well, all that was said is correct except that I think the 6.4 needs in the neighborhood of 3500 to 4k to start getting it's rated hp. Even with my 4.56, 2500 is minimum rpm. 3 to 3500 is where it's starting to come on strong. As for the trannys, F--- and it's 10 speed, I think in the end will loose out to Rams 8 speed. For one, those that are looking for the 0-60 or quarter mile speeds will find that adding one more shift is lost time. Second, adding 2 gears to a trans, and I suspect they will be trying to keep size and weight where it's at now, think you will find using it near to it's hauling and especially towing capacity, think a failure will be more probable. The Ram 8 speed is so even geared, think it will be a long time before anything betters it. The last part of the equation, I think then Ram will do well in the 25/35 series trucks using the 3.73 gears. Over the long haul, especially when towing, the 3.73 is a considerably stronger ring and pinion combo than the 4.10 and especially the 4.56. Again, sure hope Ram is considering this change. If an 8 speed can hold up to a 700 hp Charger, sure think it would do well on a 400 something hemi. "I'm Waiting". lol

The Cummins has 800lb-ft (865 with the high-output) to the Hemi's 429. They could put a 14-speed behind the Hemi and the Cummins will still be a better towing option. Not that the Hemi is a slouch or anything; it's clearly got some oomph to it.

 

[KarL45]

Agree the Cummins has about double the torque than the Hemi but in actual hp are about equal. Truth, looking at the trans gearing differences between the Aisin and the 66 RFE, if the Hemi had the Aisin gearing it would be some better. Think trans gearing is key to a much better performance than it has now. In the Hemi powerband, think it will "Hold" the load nearly as well as the Cummins but "getting the weight to the goal, the diesel really shines.

Deadline isn't too critical, She has a 4 door and is looking into buying something else, I'm trying to talk her into a R/T or SRT-8 charger.... have her 60% sold on one. As for me on days I'll need to pick up the kiddo or us going places we have her car, plus I still have my ZR-2 blazer which seats 4. but the AR-2 is slated to hit the torch to start the SAS project on it. looks like that might have to wait a little longer.

And the more I think about it the more I lean toward an older cummins mega cab. I want the 5.9L not the 6.7L. and as for towing nothing can compare in my opinion to the cummins. My 07 was a beast and regularly pulled 25-30k on a 30' goosenect trailer and other farm equipment. I'd even take my buddies F350 7.3L with a empty 30' gooseneck hooked up... Man i Mmiss that truck.

I am also stuck with what to buy..... getting something this week. I have been doing lots of research and still can't make a decision. I like the hemi of course. But to get gas mileage like the ecoD would be amazing. I did see a utube that the eco with tow haul enabled and traction off did about the same o-6O than the hemi.. can someone confirm this?

I do not tow for the most part. I will tow a single motorcycle trailer during the summer to go to the track, I might do 5-7 trips 2-4hrs each way. Is this alone grounds to opt for the ED? the rest of the time will be in town and a 40 min drive to work 2 times a week. not sure how to crunch the numbers to see if its smart to get the ed. I wanted a 15 Larime limited for the plush leather, but don't particularly like all that chrome. I also really like the sport model but will want the air suspension. And the sport doesn't come with ED. There are many models I don't know about. Again its my first truck and first domestic vehicle ever. only had German cars before.

Side question, does the hemi and eco preforms the same in snow or off road?

also someone had put into my head that the high torque on the Ed actually out accelerates the hemi do to getting the full torque right away at low rpm. He told me that on freeways its faster to accelerate than gas, any truth?

I have driven both, but now just confused as to what I need. How about if they were the same price? a dealer near me was advertising free diesel upgrade, so there's that.

Sorry for all the questions. And, please don't just say its just personal preference!! thanks all.

 

[pcschwenke]

I've driven both. There is no way, no way the 0-60 times would be close. The Eco is very sluggish. Maybe if you upped the boost and changed the computer it may be different. Being stock is a different story.

 

[Csanders1992]

From every where I have seen the Eco is slow and not fun to drive. It gets great fuel economy and will pull the occasional load though.

you wont go wrong with either but the diesel will cost more over all, I have a 2010 hemi with 3.92 4x4 and love it. cant see myself in another truck nor do I want another truck. its fast when I want it to be, tows when I need it to and still gets decent mpg

Unless you do some serious engine mods, like dpf delete and upgraded turbo the ecodiesel will not be faster than a hemi. Even deleted it won't have a 0-60 as fast as a hemi. It isn't made to go fast,it's made to get good fuel mileage.

Will one perform better in the snow? No, they have the same 4wd systems. They'll perform the same. Now off road in the snow the hemi will spin the tires faster, so that could have it's advantage.

Whoever told you that the ecodiesel will out accelerate the hemi on a freeway is a moron. They clearly have no idea what they're talking about.

Personally my next ram will have an ecodiesel, so don't get me wrong I'm not bashing it.

I'd check if that dealer is offering that diesel upgrade on HD trucks only. I've never heard of an ecodiesel upgrade for free.

haven't even heard anyone touch on the fact that resale on a diesel will always be higher than that of a gasser.

I however suggest you look at the 2500 platform with 6.7 cummins rather than the eco diesel. The crew cab offered is plenty for a car seat in the back. I have a 6 month old and actually traded my 06 cummins for a 2015 6.4 hemi crew cab initially. When the hemi would keep up with our camper needs we traded for our 15 crew cab long box ******. I am just over 6' and have never had issues with the seat hitting the car seat.

i continually hear about the higher maintenance costs of diesels, but it really isn't that much more, and if you had an 07 you know what i mean! yes they take more oil, but you can run the oil longer than you usually would in a gas job. the only extras a diesel really requires on regular maintenance is fuel filters and DEF now... and honestly I use roughly a gallon of DEF per 1000 miles. area you really going to notice an extra $5 per 1000 miles? so really the only additional cost for the diesel is the fuel filters.

the 2500 and 3500 diesel market is pricey to get into but it will net you the majority of your investment when you turn around to sell it... I traded my 2006 cummins with just under 200,000 miles for $22,000... I can assure you that most with a half ton truck with under 100,000 wont be getting that for trade...

You must sit with your nose on the steering wheel. I'm 6'1 and I had to move my seat about 3" up when I had my daughters car seat behind me, which is why it is now on the passenger side. Although if you are still using the system with a base in each car and 1 seat that might be why, that setup was about 1" shorter than the permanent monstrosity that is used later on.

ahh man... why do you have to go and ruin it for me!

yeah we are still using the clip in base thingy majig...

I do not sit with my seat all the way back. I sit where my arm is fully stretched to the top of the steering wheel... no issues as of yet, even have a few inches between the back of my seat and the car seat...

Sorry to spoil the "fun"! I sit all the way back and up one slot on the manual seat, which is about a inch or so up from all the way back, hopefully you will fare better than me!

I'm 6,4.. we have 20 month old twins.. I love me mega cab.. except for when the wife wants to drive and expects me to climb over the center consol into the back to help with the kids, I can do it but not as easy as she can at 5"4. The car seats are huge..
