Cool Fuel economy difference between Ram 2500 Hemi and Cummins?

Hello everyone, I would like to know how many MPG does the Ram 2500 Hemi or Cummins get? If anyone could compare the fuel economy on both engines that would be great. I really want a Power Wagon but I would like to know how is it on gas or if I would just prefer the Cummins heavy duty truck. If the fuel economy of the Hemi on the 2500 is somewhat similar to the 1500 I would stick to it only because I love the Power Wagon.
Thanks.

heres my take on the hemi vs cummins engine. first, my 04 5.9 cummins 3500 wa totaled back in jan. i fully expected to replace with the same. here is what i found. my 5.9 4x4 would produce an average of 20 mpg on trips from nj to florida. the new 6.7s as i have been told the 6.7s only do about 14mpg. the 5.9 was really a simple engine and bullit proof. 160000 miles and not one repair was required just maintanence. oil changes and fuel filter. had valves adjusted at 150000 miles. 6.7 have all new epa polution controls that are causing soot problems and have killed fuel mileage. so unless you need the towing power of the cummins, you will pay more for fuel, get less mpg than 2500 hemi and possibly have soot problems if it is going to be a daily driver with lots of short runs.

Buddy of mine traded in a 6.7 auto 4x4 diesel with 150,000 miles on a Hemi 2500. I told him he'd hate the hemi towing. It took him 12,000 miles to say I was right. Difference pulling about 9,000lbs was 9/11 mpg versus 12/14 mpg and having to mash the hemi to the wood pulling in any kind of inclines. He unloaded the hemi 2500 truck. Oh both were 4x4s. Both trucks were 3.73 geared. He tows about that same weight 50k a year. He says what the auto 6.7 diesel walks off with the hemi was floored and screaming. Sounds about right.

The terms "POWER WAGON" and "FUEL ECONOMY" have no business being used in the same post!

Well the 2500 Hemi and the 2500 Hemi Power Wagon are two entirely different animals. Don't expect anywhere NEAR the fuel economy with the Power Wagon that people with normal 2500s get. The Power Wagon is a 4.56 geared, heavy as hell, off-road beast and gets the fuel economy one would expect from such.

A 6.7 doesn't deserve to hold the venerable old 5.9's jocky strap. That's not a real dig on Cummins, NOBODY's modern, environment friendly diesels are on par with any of the later non-emissions standards engines (except maybe Furd, but that's because the 6.0 Power Joke was a total POS). You can thank the government and the tree huggers for sh*tty diesel engines being offered today.

But you'll still get an easy 25% better fuel economy with a 6.7 CTD than a Hemi equipped Power Wagon, even better when towing.

If you need a full size truck and are worried about fuel economy, get an MDS equipped 1500...

I was looking into the same thing before buying mine. I determined that unless I am going to be pulling every week, the cummins was no good for me. With my hemi, I do 20-22mpg regularly, I do mainly highway, but even in the city I would do 14-15. Might I add thats highway mpg on my 07 1500. You would be lucky to get that out of a cummins. However when I pull, that would go down to 9-10, where as with a cummins it pretty much stays the same. So unless your pulling, don't go cummins.

This brings me to my next idea, that kinda might straiten things out. Is if you are not pulling, and don't need the cummins, why not just go with a 1500? The ride difference is UNREAL due to the coils. It rides sooo much better. Ya depending on how much your going to pull will matter, but if its just holiday trailers and the odd pulling, this truck will do mighty fine. Theres a lot to say about those coils.


Also I think the days of the power wagon are coming to an end....

Your getting 20-22 with a 1500. Not a 2500. There are times a 2500 is needed.

Yes I do drive on pretty flat barron land too, im in eco more than 80%of the time.

There is a place for a 2500, but I was trying to emphasize the fact that unless your doing heavy pulling or very large payloads all the time maybe a 2500 might not what hes looking for. obviously he is looking at fuel economy, and the 1500 hemi will get the best out of everything. Vs a 2500, just what he asked is all.

I'm now getting an idea, I just wanted to compare the fuel economy between the Hemi vs the Cummins. I knew that the Hemi on the 2500 is a thirsty engine, since it doesn't come with MDS. I just wanted to make sure if I was correct and if it had some improvements on the 2011 truck. I never tow, but I do want an extreme off roader which is the Power Wagon and I do wan't to keep it on my wish list. I think that depending on my needs later on, I might even stick with the Cummins. I mainly want the 2500 just because it has a front solid axle. I prefer those over an IFS.

Yeah, I know where you're coming from, my '04 Hemi 1500 is my first IFS truck of seven full size 4x4s I've owned, it will be my last. Too much to worry about and too many limitations when lifting.

Keep one thing in mind though, a Cummins is a HEAVY engine and places a LOT of weight up front. The guys in my hunting club who get stuck the most in the lowlands and swamps we hunt in south Georgia are the ones who own diesels - by far! I've even seen guys with lifted 4x2s with rear LSDs and lockers drive around stuck Diesel trucks with their noses down and buried in the the soft sands and red clay where we go.

I've even seen a Powerstroke stuck up to it's front axle in the sand on the beach in north Florida, while the bikini clad chicks were driving around them in their little front wheel drive Civics, LOL...

I can give you a really good idea. I have owned every cummins Dodge except a 12 v, and you can see what I drive now.

My last truck was a 2008 6.7 I got about 16 mpg hwy and 10 - 11 towing. When it was not in the shop. I even deleted all the emissions equipment off the truck so it would say out of the shop, and I just found other new issues like my G56 transmission and DMF.

My 2009 hemi on 87 octane (no corn juice!!) will get 15 mpg hwy and about 8 - 10 towing the same load about 8K lbs. I also have 3.73 gears, so if you got a power wagon you can expect less mgp for sure but I don't know how much less. It also pulls it without any issues at all. One thing is these motors like to rev up, but that is where there power is it is a V8 after all.

I had a ton of issues with my 6.7, and it was the biggest pile of junk I ever owned and I will never go back to a 6.7 again. My 5.9 cummins trucks all got about 18 - 20 mpg hwy and about 12 - 14 towing the same load, and by the way never had any issues with over 100K miles on each of them. They all had NV5600 or NV4500 manual trannys in them as well.

If you are not pulling a huge trailer eveyday then I would say away from any newer EPA loaded diesel.

I have only had my 2009 2500 hemi for about 6 months, but so far not any real issues. I have a whine noise in 1st gear, but some say this is normal either way it would be covered under my CPO. There is so much less to worry about with a gas hemi 2500 over a 6.7 I don't even no where to begin. The maintance on a hemi will be way less, and it will be in the shop a lot fewer times.

i have a 2009 1500 for personal truck and have hated the coils in the back. dont like the ride and i have had complaints but nothing to be irate about. at work we have 2500 hemi's and 3500 cummins. never has our company had vehicles gone into the shops more then those two trucks. the rads are to close together and the things gunk up and overheat, they cant take the abuse off a paved road. the dashes are lit brighter then a christmas tree and like others said, they new diesel engines dont get anything for mpg. our chevy and ford gas jobs are gutless *** hell compaired to the hemi but not a single truck performs as well as the duramax's we have. ive been a dodge guy for years and my last few have been dodge. next one.... duramax.
(work conditions are that of open pit coal mining, carrying toppers or service bodies. deep potholes, mucky conditions, lots of rocky terrain, lots of up and downhill grades, dusty)

What issues did the 2500 hemi have that were so bad?

Wheel hubs, ball joints, and ujoints?

Or was it more serious like motor and tranny?

Wow. The ride with the 1500s is great. Hiuge selling point is ride and coil springs. Like my truck a lot. You never read anywhere about complaints about ride in a 1500. Duramax has not got a stellar rep. its ok. Much improved over previous years. But you got to pour urea in them. I learned long time ago you can keep a V8 diesel of anybodys. Old Dt466s were ok but not great. There is a reason that most all you see running 'hotshots' are Dodge trucks. Few older 7.3s out there doing that. Never see a Duramax. Wonder why?

----------well how about this for a wfirst post,,,,---------

well its because hotshot drivers loose money each time their duramax blows up in the middle of the job.


i have the dreaded 2008 6.7 4X4 1 ton dually QC, and yes it sucks fuel .but it also pulls like a train.
i just had the a CAI ,5" exhaust, and a H&S programmer installed.
the power gain is amazing off of the seat Dyno,but MPG's did not get much better from 14 to 18 in the city and 18 to 22 in the HWY (11 MPG with 10,000lbs 5th wheel behind it).
i have the 1500 '10 model and i gotta say, its about the same as my 3500 that has alot more power and torque, but also more of an initial investment.

My 2003 dually has never hit 20 mpg hwy. unloaded. Its gets 11 maybe,just maybe 12 in the right conditions pulling 12k to 13k at 68 or so mph. But it pulls so good that it takes a heck of a incline at 68 mph to have to drop from 6th to 5th gear. I pull a Merhow 3 horse 10 foot shortwall Living Qtr horse trailer.

My Brother has a 2010 Power Wagon and the rig is a tank! If you are highway driving you can get 14-15 if you are going 65. Tows awesome with a enclosed trailer with ladders and a full 250 gallon water tank in the bed. But again you are looking at 8MPG in that scenario as well. Taking into consideration the maxxed out payload and trailer on the back it tows very nice. He's owned it for 6 months and almost wished he bought a cummins, but when you compare the price of a fully loaded cummins CC to a load Power Wagon, well there's your answer right there! He paid $33 K for it with 1,800 miles on it, it has solid axle, winch, 4.56 gears, navigation, dvd player, and all the other cool stuff that a loaded cummins would have, just no leather or cummins. So for $17000 less than what a cummins would be he's fine with crap mileage while towing, and he has a cool rig that not too many people have!

That is one heck of a price on a 2010 power wagon.

I would love to have that truck. That is about what I paid for my 2009 with 16K miles on it 6 months ago. I paid $29K for my 2500.

When looking at ANY of the new diesels, two questions pop up, warranty and reliabilty. You do not get to have both.

If you want a warranty, you won't have reliability. If you want reliability, you won't have a warranty. Plain and simple. Any of the new diesels need to have DPF and EGR deletes to become reliable, and then your warranty is down the tank.

I'm in the market for a new truck, and reliability AND a warranty are tops on the list. I have an 03 on it's second engine sitting with a huge hole in the block, and my 07 is still kicking for now (after a rebuild of it's own). So, wanting both reliability and a warranty, the new 6.7 is, unfortunately, not on the list. Just drove a 1500, but the 2500 is likely the way to go.

Don't get me wrong, I'm a diesel fan all the way. I just can't shell out dough on making the 6.7 reliable and tanking my warranty at the same time.

And anyone that talks down on a Duramax has their head so firmly planted up their a$$ they are obviously lacking oxygen to think straight...

The Duramax is a bad mother, it's the best diesel on the market in 100% stock guise. I'm a Dodge/Cummins man all the way, but the Duramax is damn good. The truck it's in has it's issues though...

Most any diesel you see pulling for a living is Dodge/Cummins. In fact I've neer seen a Duramax being used for that. Some Ford. Dodge dominates that role. Wonder why?
