You all seened by now that GM is advertising 680 miles per tank on a 36 gal tank. Thats just crazy on a truck putting out 765ft lbs of tq out of the box. Really kinda pi$$es people off like me that have a stock LMM that are getting 13.5-14 mpg. But hey that is good for GM though, its just different to see a company finally putting out pmg numbers on a diesel.

Here is s funny too, just looked at GMC's website and they say the new 2011 HD is coming out in the fall of 2011. Uh I think they mean 2010.

I just drove 575ish miles and got 24.x mpgs. Kinda low for my truck tho

probably for a reg cab short bed 2wd. 5500 lbs ;)

well i hope it gets better than 18 b/c ford is reporting in the 20s all the way up to 29. so chevy had better step up to the plate, i dont care how much power or torque it has they can get better than that.

Dodge is going to be getting 30 -34 MPG. NOT!!!!:p:

Man if you believe you are gonna get 20-29 MPG with the new Ford, I'd love to sell you a nice life insurance policy and some beachfront property in Arizona.

No way in hell is a stock 6.7 turd gunna get 29. LMAO....

It scares me that people gullible enough to believe this are able to reproduce and/or vote. Please tell me you're not old enough to do either.

im just telling you what was posted. these guys drove the trucks and thats what they had said, time will only tell.

Hey man i dont say anything to you bad or anything, so layoff i had just read that and about the fords it didnt come from them, it was like pickup trucks.com or a place like that. they had drove the trucks and tested them. so dont sit and say im gullible, i know these trucks can do better in the mpgs just like with the rest of the chevys with a little tuneing and such. so if chevy is only reporting 18.88 i just hope its better thats all. b/c for a d-max to get in the 20s is not unheard of and is very possible. the only reason im on this forum is to look and c what they new chevy is gonna be like, and this forum has good info on the new trucks. so dont bash on me, b/c you made a mistake and voted for OBAMA, SO LETS HOPE YOU DIDNT REPRODUCE, or who knows maybe ur still on the nipple.

I read that too except the one detail you left out was that mileage was on a dirt road going up hill.):h

): maybe his spell check is not working

that "1e" was supposed to be "13"

all im was wanting to get out is that i hope that it gets 18 or better.

Hey Buddy don't pick on brown haired or brown eyed people cause I have both lol. Now worries here though:D. Well thats some pretty good milage that GM is claiming I'm guessing that is with a non dpf, non egr, equipped truck with a all fiberglass body lol:rolleyes:. Those numbers had to be taken from a engine on a dyno that had perfact simulated conditions is the only thing I can figure.

Here's the problem. Gm is saying 680 miles per 36 gal tank. They let us figur out that means 18+ mpg.
Ford (as far as I know) has not said anything specific about the economy of their new truck other than it gets 15% better economy than the outgoing model. We all know the 6.4 got poor economy compared to the LMMs.
So now we have a magazine that hypermiled the hell out of a 6.7 to get 26 mpg calc'd by the truck over an 80 mile run. Now we have idiots who didn't actually read the article citing it and thinking they'll get 26mpg in the new ford.
All I can say to them is good luck! You're gonna need it. Either that or a semi going 54mph 25 feet in front of you wherever you go.

Ok, you convinced me; I'm trading my Duramax in on a new 29mpg Ford.

And if you believe that, then you probably would believe I voted for Obama as well.

Ok, serious. 18mpg is very respectable out of the box for any stock 7000lb truck with the aerodynamics of a polished brick. If Ford achieves 18mpg with the 6.7 I'm guessing they'll be ecstatic considering what they see with the 6.4. Your post was written in a manner that gave credibility to claims of getting as much as 29mpg in a 3/4 ton truck with a 6.7l diesel. From what I've seen in the REAL world (including my own experience), 29mpg would be about double what the 6.4 is getting.

Yes, I've seen the posts claiming Duramaxes getting mileage in the low 20's, but I have yet to see anyone try to claim mileage in the high 20's. I've owned 4 Duramax trucks now and haven't seen better than high teens for mpg. I guess others who drive more conservative may achieve a bit better but within reason. Maybe if GM follows through with the 4.5l in a 1/2 ton we may see 29mpg but I doubt we'll see it before then.

And yes, you are correct on point--I am still on the nipple, and I don't plan on letting go for about another 40 years. ):h

Yes i agree with all of what you just said, i also think 29 would pry never happen. Well i'm glad that we got that all settled now. I knew i was setting myself up with that post. But all fun and games have to have a little excitement.

Doesn't the F250 also come with 3.55's and a 33-34" tall tire too (factory 20's)? That would definitely help your highway mileage.

Doesn't the F250 also come with 3.55's and a 33-34" tall tire too (factory 20's)? That would definitely help your highway mileage.

You're correct on both counts. 3.55s are available, 33" 18s and 34" 20s are the exact wheel sizes.

For the record, Dodge offer as high as 3.42 but they now have the smallest stock wheels- 31.5" max vs 32.7" max for GM and 34" for ford. I don't like tall factory wheels for mpg as the lower revs are cancelled out by the increased engine load and rolling resistance, it's for increased ground clearance.

Ford promised improved mpg over the 6.0 with their 6.4 and it returns single digits. I don't trust any mpg figures until they've been driven by consumers for a year or so.

u should expect that kind of mileage (should be more) out of this new truck when its not buring diesel to meet emissions. the lmm can get that when you take the particluar filter off and a tune.

Man if you believe you are gonna get 20-29 MPG with the new Ford, I'd love to sell you a nice life insurance policy and some beachfront property in Arizona.

Every one tested so far has done 22MPG or better :D

29+ MPG

Ford is claiming an 18% improvement in fuel economy over the 6.4 so I wouldn't expect any better than that

With a duramax u need to defend your self?

Guess it may be true about the numbers. Pickuptruck.com just posted testing one of the new Fords with the 6.7 and totalled 22mpg with 1000lbs in the bed. Thats amazing. It will be interesting to see more info once its out. I'm amazed that a 8000lb plus truck could show these kinds of figures.

The way these tests are being performed, any truck could get "incredible mileage". Going 45 mph down the interstate is not a good test. How about a test of about 250 miles though the rolling hills with 20mph winds, and going 72mph on the cruise. A stock 04' LB7 can get 19.6mpg under these conditions. Would love to see a real test with a new LML or powerstroke.

X2!!!
I have yet to see an honest real world test. Until then its just anecdotal data, interesting but not very useful.
Here I'll give you an example, last week I filled my tank and zeroed out AVG MPG, then drove to work drafting behind a Semi for 25 miles at 70 MPH or so, at the end of the 25 miles as I was getting off the freeway AVG MPG showed 24.8 MPG, so I guess my LMM gets 25 MPG. Wow aren't I lucky.

Again interesting but not useful.

i agree with that. most of these trucks can get 20 or better when driving 60mph, no load, no wind and no hills. Its all the other stuff that starts sucking fuel. However, i'm still interested to see real world numbers from both chevy and ford when the new ones hit the road. i think dodge will behind both of them.

Going down hill,strong tail wind and empty fuel tank.
without the wife:eek: and fordCensoreding sucks

I became a mpg geek shortly after buying my present truck and have been watching the developments in fuel economy in diesel pickups and elsewhere. Here's what I can tell you:


The new Ford's and Chevy's will both get very good fuel economy and both will be dramatic improvements over the 2007 emissions engines. I'd expect "average" drivers to get high teens to low 20's in mixed driving without towing or hauling.
A significant part of this will be because of SCR, but they're both making other improvements as well.
I'd expect Ford might come out slightly ahead because of all the stuff they were able to do with a clean sheet design, but I'd expect it to be very close. Ford is claiming 18% improvement in pickups, GM 15%. I don't know how they compared in the previous generation though - do you?
Dodge/Ram isn't using SCR for pickups, so I doubt their mpg will be as good as Ford & GM, though they at least still offer a stick.
Tremendous fuel economy is possible in the Ford (and probably new GM too), but any number you've heard above about 25 is probably not ever going to be seen by the average driver. One particular hypermiler drove one of the Ford's from Phoenix to Chicago and hand calculated 28 mpg w/ a crew SB 4x4 w/ 3.31 gears & tonneau, but this is far from normal driving. Mirrors folded in, 45 mph, starting in 3rd gear, etc... He stopped here along the way and I got to talk to him a while and check out the truck. More details here (http://www.cleanmpg.com/forums/showthread.php?t=29847&page=5)
The same truck was also tested at highway speeds on CC. Check the link above towards the bottom of page 5. This is probably the closest to real world data you'll get until people actually start buying them and using them.
My truck can still match mpg with the best of them :) I average maybe 25 mpg in summer and 22 in winter, doing some special things to improve mpg, but nothing like the hypermiler described above. As long as it runs, I'll never buy one of the new ones with an automatic.However you feel about Ford, it will be fun to see Ford and GM duke it out over the next few years. Whichever brand you like, they'll both be getting better from the competition. I don't know what to think about the Ram - it's just so different.

Have you lost your mind? Under the above stated conditions I have driven a duramax, 13 miles per gallon at best. I'm not saying thats horrible, mine probably would have gotten 11...

Have you lost your mind? Under the above stated conditions I have driven a duramax, 13 miles per gallon at best. I'm not saying thats horrible, mine probably would have gotten 11...

Really????
I know with my LMM I'd get about 17.5 MPG under those conditions. Mine's bone stock BTW.

How do I know?? Lifetime average for my truck is 15.94 MPG with ~30 % of those miles towing, on the road trips I've taken without towing I average about 17.5 MPG with CC set at 79 mph

So maybe the new trucks get what the '06 models did. My '06 I can repeat 22+ MPG. Has to be in the high 70's or 80's and going 68 MPH also can't be using winter fuel. Pretty much this whole discussion is useless w/o the actual data. I see they were doing 1000 RPM. How do you pull that off? at about 55 or even 50 I'm doing about 1200. Face facts this article is more about writing articles that get people's attention then it is about discussing the true economy of a HD Diesel Truck driven daily.

The new trucks will get better MPG than the previous ones. The urea injection allows them to run more fuel efficient fueling while still running cleaner.

Have you lost your mind? Under the above stated conditions I have driven a duramax, 13 miles per gallon at best. I'm not saying thats horrible, mine probably would have gotten 11...

No I haven't lost my mind. I can duplicate it anytime. You may have driven a duramax, but not mine. To only get 13 miles per gallon yours must have something wrong.

i agree mine gets 23mpg highway and i have 500# minimum in tools at all time in back.

Im thinking bout goin to a powerstroke forum and bitching bout my old truck that i dont even have anymore. :wtf:

Fuel economy is important but I like to think reliability has more to do with what truck I buy. We got a guy on here that's running over 400 000 klms on an LMM and has needed to fix nothing more than a radiator and brakes. He tows 14000 lb trailer for 95% of those klms too. (forum is labeled 200k +miles on an lmm or something...)

Ford has not been known for that kind of reliability really...

I bet these trucks were new with very low miles, see what happens with more miles on it and a filter starting to clog. Plus who the hell is gonna get on the highway to hyper-mile a truck??? If you can afford to buy a truck that expensive then fuel shouldn't be a worry, if you can't afford it don't drive it, I buy trucks to work not to get good fuel mileage!!! You want high fuel mileage go buy a hybrid and I'll keep rolling coal regardless of mileage!!

Good fuel economy is like a "cool fad" in the diesel world. For example: if your diesel doesn't get "good" economy then that's not cool. It really has nothing to do with the 2 to 3 extra dollars and miles give or take.

Well if people like diesel with fuel economy i bought my wife a tdi jetta that gets 48 at 75. Just not concerned about mileage on my truck because i know that same model in gas motor would be a lot worse with all the stuff I put on a truck, so put me in the teens and I am happy.

I'm pretty sure the new fords can be had with a 3.31 rear axle as well, which is probably the one used for the 29mpg test. I'd like to see how a duramax could do with those gears.

I get 19 ish most of the time on the highway which I think is good and every once in a while I'll see 21. I do not really try all that hard to get good fuel mileage but I drive my truck sensible most of the time. I think advertising a mpg number that was hyper miled is insane. There are gonna be some people that buy the new ford just for the 25 mpg or 29 mpg claim. That's a problem just waiting to happen to ford when true mpg doesn't break 19 mpg. I would not want a diesel truck with a 3.31 gearing with 20" wheels. I wish I had 4.10's in mine now. These trucks are made to pull heavy stuff and get reasonable mpg. I do think the current diesel trucks should get better mpg, but I doubt we will see 25 or 29 mpg from normal driving and the average person.

The reason for the increase in mpg in the 2011s lies mainly in the changes to the emissions system. In the LMMs, some exhaust gas is recirculated through the engine to reduce oxides of nitrogen, which in turn produces additional soot. As a result, the DPF requires a regeneration cycle more often than would be the case if there was no exhaust gas recirculation.

In the 2011s, the addition of a new SCR (selective catalytic reduction) catalyst to the DPF reduces the need to recirculate exhaust gasses through the engine. Instead, the SCR breaks down the oxides of nitrogen by utilizing the ammonia formed from the urea injected into the exhaust stream. This in turn means that more clean air and fuel can go into the engine instead of recirculated exhaust gasses, and greater power and torque can be developed in the engine.

The frequency of regenerations is also reduced, which enhances fuel economy even further.

Just not concerned about mileage on my truck because i know that same model in gas motor would be a lot worse with all the stuff I put on a truck, so put me in the teens and I am happy.I did the same - my wfe rolls a 2003 TDI Jetta wagon - 51mpg if she doesn't let me drive (having the manual makes me wan to drive it like a sports car) - 43-47mpg when I get a couple laps in.

On the trip home from the dealer, my wife was doing ~75 w/o cruise, and the DIC said 18mpg when we got home (in our 2010). My 2005 would've been similar, from experience, which is nice. I just need to keep it in the 17-18mpg range.

100% diesel at my place - DMax, TDI & my '83 K5.

Hahahah I hear you on the sports car part, put the 17's on the tdi, so the handling on curves is great. If chevy drops the 4.5 in a 2500 suburban I am all over it, for now we have settled with the 6.0 on the 2500 suburban for a travel vehicle only gas i will ever own!!
