Well I thought that I would start a comparison in which the Titan XD would win (kidding!)

So we are starting to get info on the gas version of the Titan XD and it would
be interesting how the would stack up against each other. So here goes:

Price: We have never seen a case in which the gas version of a truck is cheaper than the diesel. The only question is how much cheaper the gas will be.
Advantage: gas

Payload: We all know the gas will be lighter and therefore more payload IF they keep GVWR the same. Manufactures have given lower powered trucks a smaller GVWR so who knows
Advantage: most likely still gas

Towing: I very much doubt the will give the gas the same towing capacity as the Cummins, but then again the Cummins usually can't tow more than 10k# with it payload anyhow
Advantage: Diesel - just keep pin weight at 10%!


Overall Performance: The gas will no doubt be better in braking and acceleration in everyday use.
Advantage: gas

MPG/ Miles per $: A year ago I would have said the Diesel for sure, but now I am not so sure. If the gas requires premium, the diesel will probably win in MP$ given the same MPG. Unknown for now
Advantage: ?

Ease of Maintenance, Convenience: Ok we wont go there

The 04-06 non vvt engines made "305" hp @4900 and fell off a cliff after that, all while shifting at 6150 rpm.

These new engines peak @5800, shifting at 6k (looks like it).

I wouldn't be surprised to see a 100-120hp difference at 6k+

My 06 base KC 4X2 went down the quarter 14.99 bone stock and 14.54 with cat back/cai in a not so great DA.

The gas XD will be quick and the "half ton" will fly imo. I predict they'll be close to the gm 6.2.

Yeah with the better torque curve, it will be much closer to the 6.2L Gm than it would be the 5.3L. Best of all premium ilfuel is not needed.

A couple of good points on the 7-speed: direct ratio 5th means good efficiency in that gear pulling a medium trailer. Also 1st and reverse are close numerically which is desired by snow plowers. The 6r80 is good here too, however, the Ram 8 speed is not.

Dont mean to beat a dead horse but compare the ratios of the 7-speed to a 6r80 multiplied by 1.17, which could be done by installing 3.92 gears instead of the 3.36 Titan XD:

7-spd: 4.89 3.17 2.03 1.41 1.00 0.86 0.78
6R80: 4.89 2.74 1.78 1.33 1.00 ----- 0.81

So yeah, basically the 6r80 with an extra gear jambed right before 6th. Nissan 6.1 speed.
At least the engine will be awesome.

Looks like C&D has some new pricing info on the 2017 F-250: http://blog.caranddriver.com/2017-ford-f-250-super-duty-sees-price-increases-of-150-to-5070/

I added $2800 to the prices to convert them all to 4x4 which was the stated cost. All are 6.2L gas prices with Screw 6.5 ft bed.
The standard cab config only added $1k or less vs the 2016 models
Scab and Screw models added around $3k. The Platinium added over $5k but looks to have separated itself from the King Ranch, unlike before.
Ford F-250 // Nissan Titan XD

XL $40,125 // S $38,290
XLT $45,230 // SV $42,010
-------------- // Pro 4x $45,970
Lariat $51,430 // SL $50,030
KR $58,255 // PR $55,520
Platinum $66,105 // ----

Price looks to be in The XDs favor a bit depending on how the features line up. The new super Duty is pricing the Reg cabs aggressively to stay dominant in the work truck category. The XD will be a tougher sell here.
Diesel adds $8600 to the Ford and only $5k to the XD, but those are not really in the same class.

Thanks for adding this to the thread, digitalbliss. Your last link needs fixing btw. It wasn't a perfect test, but much better than most do. The diesel was about 10% better towing and empty, and the testers agree that the $5k premium for diesel is not worth it. That goes double after seeing the poor turbo diesel performance on the IKE, which is high altitude. Closer to sea level, the 5.6 will have an even bigger advantage.
Many will still hold the claim that the diesel is more reliable. We are seeing evidence that this may not be the case, at least for the XD. Other than the tailgate and paint issues, it seems that all of the problems posted here come from the Allison/cummins, whether major mechanical or simple anoyances like shuddering.

Who is we and what evidence is being seen? Evidence does not support a "may" or "may not" be situation. Evidence supports an "is" or "is not" situation. You cannot make claims like this and then enjoy the freedom from responsibility by not taking a stance on your own statement. That is absurd.

And none of these trucks have the required hours or miles to even begin to gather a perception of reliability - Initial quality yes, reliability 100% false.

Also, what is your classification or major? I garuntee it is not the correct classification, because if that where the case WE THE FORUM would have heard of some sort of catastrophic failure with either the engine or transmission that would have required something besides a TCM/ECM Flash/Replacement.

Quit stirring the pot.

My last post said major problems OR simple annoyances, which things like reflashes, tcm, shuddering fall under. There has been major mechanical as well. Using a smart phone and dont feel like linking the threads.
Sheesh! The diesel defense force was quick on that one.

Honestly as far as vehicles go the things mentioned here are pretty tame compared to other manufacturers. So far it has been my experience that Nissan has if anything overreacted to any negative criticism regarding problems with the truck. I've had several brands before and honestly they've done a really good job on a truck that is completely unproven for almost every component aside from the frame it shares with the NV3500.

It's certainly way better than Mazda or GM who prefer to bury their heads in the sand and hope the problem goes away. Just look at all the bad press the new Tahoe/Suburban/Yukon is getting right now with the roof buffeting problems or Mazda with their injector fouling problems; don't get me started on Ford's trannys either.

For all the problems mentioned here in the forum at least they seem receptive about fixing it. Plus a year or two from now there "technically" isn't anything stopping them from releasing a final ECU tune that could significantly boost HP like Ford did with the Powerstroke 6.7.

Undoubtedly if you want a more proven platform go with the Endurance 5.6. It's been around forever in the Patrol and has a fabulous track record which cannot be said of the ISV....yet. It's way too early to be writing its obituary; Cummins has a very good track record in general and honestly only time will tell.

Lets not forget about those losing power when there is still about 5 gallons of diesel left (with an already small tank). Oh, and of coarse, the complaints of smelling diesel. Hard to put a price on that one.
Then again, we can ignore all of that and wait to see which engine lasts past 300k which is the ONLY thing that matters, it seems.
 
#61 ·
Lol your grabbing for straws. Go to any diesel truck forum and everyone one of them has a thread about the smell of diesel exhaust. The ECOdiesel had a flippin recall for it. No that is not justifying my purchase @6Scorpian7 that is just a fact.

And how many of those trucks lose power at 5 gallons till empty? You say it like its an epidemic - like its a 100% fact that you will experience this. I have never had that happen - AND I OWN THIS TRUCK.

Seriously, I under stand people have opinions and blah blah blah......but if you are going to come around just to drop some bull s**t on the forum without substantiating any of it then just don't bother coming around. It is getting ridiculous.

Maybe I'll just stop coming around. That is the easier of the two I imagine.
 
#63 ·
Don't get lippy with me. If you don't like my thread because it hurts your feelings, then tough. There ARE several threads on the loss of power issue btw. As for the diesel smell, just because alot of other diesels have the same problem, does NOT make it ok for everyone. After all, this is a thread about the gas Xd vs the diesel Xd and NOT the Xd vs other manufacturers, but I doubt you can comprehend even that.
 
#65 ·
LOL - are you my mommy now? Getting a little upset because what you said holds no weight and someone called you on it?

My feelings are not even the slightest bit hurt......you act like just because I bought the truck that my comments are coming from the position of trying to defend it or some sh**t. When in fact my comments are coming from the position of being annoyed to death from people like you who just say crap as if it were fact with out having anything to substantiate it.

I don't care what anyone has to say, but if you are going to say it be able to prove it, other wise don't say it at all. Especially when you are taking the stance of fact over opinion.

Have you owned a DI-G vehicle before? For all the problems the diesel may have I don't think you're taking how seriously the possibility of fouling could be with this engine. There have been well documented cases from many many manufacturers that would make me worried about keeping one more than 5 years without aggressive maintenance.

So far, from the things I have read on this forum, the most major problems I have seen were the replacement of a transfer case (maybe even two). I also know there was one post showing a screenshot from a dealer replacing a Cummins 5.0 engine, but there wasnt any more info than that.
Which for a first run vehicle isn't bad at all, the worst systematic problem is the tailgate so far. That said we will see how the DI-G Endurance holds up; if it's anything like other DI engines I've had in the past it will have problems with fouling which gives people three options:

#1 ) Always run Top-Tier Gas *plus* the occasional High-PEA additive knowing you will have premature spark plug failure.
Or
#2 ) Run cheap gas with regular High-PEA additives and again risk premature spark plug failure
Or
#3 ) Roll the dice and see what happens at 20,000 miles+ and hope you don't need to sand/walnut blast out the crank case + valves.

This is a very real risk that I don't think people have addressed here yet. There's a reason why Toyota, Subaru and others have moved to Port AND Direct injection for their future motors. Just look at how bad the Ecoboost motors are for fouling problems if you want a reference for how it could go.

Yea see what I mean, I'm not trying to defend the diesel's legitimate shortcomings but the gas could grenade just as easily or it might not its hard to say. The only way we're going to find out is in about a year or two. A lot of folks like myself are betting that the truck will hold up reliability wise and if it does the resale on it especially the diesel will be sky high especially when they get the tune right.

But even this assumes that Toyota does NOT release a diesel Tundra/Taco. If that happens I suspect you'd see a ton of folks including myself seriously consider defecting to a legit Hilux but it doesn't seem likely. I just don't trust DI engines at all, I've had several foul and many family members have as well which is why I religiously run Redline/Techron on my wife's Tahoe. Plus we plan on turning it in at year 5 because again I don't trust a strictly DI platform.

Here's a start:

- questionable experience in the consumer 3/4 ton-ish US pickup market
- still building a base of trusted pickup customers
- hokey, niche tweener business plan
- underwhelming tow/haul specs
- acquired taste looks
- excess heft
- marginal fuel economy
- marginal acceleration
- the XD gas engine option out-pulls it even at altitude
- poor value
- no exhaust brake
- first model year
- 3/4 ton competition is tough
- ....
Your post doesn't make sense. Thread isn't xd business plan. It's xd vs xd.

Since this is a diesel vs. gas, XD forum, I'll post some gasser info. First substantial pull, 4500 pound travel trailer, highway/interstate travel. 9.7 mpg, average speed of 65 to 70. Trip home with new camper, 6000 pounds, 7.9 mpg. Truck had plenty of acceleration, power and stability. A few times I looked down and realized I was running 75. The only issue I experienced was an almost violent downshift at 40 mph. If I touched the brakes at 45 mph the transmission would shift from 6 or 7 to 4th instantly causing RPMs to jump from 1500 ish to 3k plus, only happens in tow mode, regular mode is silky smooth. My truck does not coast like the older ones, it acts almost like an exhaust brake.
