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

oops, should rear gas engine is always cheaper. So gas looks to have all the wins or projected ties except towing capacity but that is a bit sketchy with the diesel's low payload.
I would guess the V-8 would be around 10k# which is around where the Ram 5.7, GM 5.3, Ford 5.0 max is.

Figured this thread could use a review.


Which one holds their value 10 years down the road. Diesel for sure ( a win ) ?
I agree with your opinion on the towing but the diesel should have 2 more advantages; longevity and resale. Of course, nearly every vehicle is a depreciating asset but comparing resale prices of the big 3, the diesels tend to hold their values better, especially at higher mileage a because people know that they last longer. Somebody would be more willing to buy a diesel truck with 150k on the odometer before they buy the gas.
It'll be interesting to see values in 3-5 years. Hopefully they don't plummet like the first gen Titan.
This is my first diesel that I have ever owned before I bought my XD I did a lot of research on diesels and the one thing I found was if properly maintained diesels will far out last gas engines and hold they resale value.
The Cummins clatter and turbo whistle is worth the 5K. :grin2:....
But in all seriousness, overall Engine life will also be arguably much greater with the Cummins.
Wrong, Wrong, Wrong, and Wrong. BTW, that Cummins 'clatter' is the impeller hitting the housing :

I drove the gasser Pro4x yesterday and I really like it. For a big truck it was still fun to drive. The transmission felt similar to or previous generation, it always seemed to be in the right gear, with very quick/solid shifts.....completely different than the GM 5.3 6 speed experience.
I think I will be getting an SV at the end of the year.
Actually, this is the biggest complaint of the gasser:
http://www.titanxdforum.com/forum/5...69-nissan-titan-xd-defects-issues-problems/17049-5-6l-7-speed-transmission.html

So the actual owners in this forum there is no need for them just have them leave the forum and leave it too you real world experienced non-owners. That will make for a very informative forum. Have at it.
I had one real incident with mine. But as I have mentioned before slight change in driving style takes most of it away. And with miles it's also less noticeable.
No, we value your input (creepy Joker laugh):

The diesel 4x2 S model has the highest row rating (12,314). But with a 2000# payload capacity and a 20% pin weight it can't tow more than 10,000# on a gooseneck, which is meant to be one of the big selling points of the truck. If you're looking at the truck as a tow vehicle you lose 2000# comparing the gooseneck to the hitch.

Assuming the gas XD has the same tow rating, and a higher payload capacity because of the lower engine weight, maybe we'll see the gas XD have it's gooseneck towing ability match that of it's hitch ?

There was a formal report done on here by U of Michigan. The diesel was bettef in most cases but this was do to diesel using less fuel in those cases. Depreciation of the vehicle itself was very similiar between the gas and diesel

edit: the thread was started by tiger7. I am too putsy to link it on my phone. Looking back depreciation WAS better over 5 years with a diesel, but much less so in a truck. In fact, Ford was worse - due to the awful 6.0 and 6.4 engines that they were polling.

advantage: diesel
 
#10 ·
I say capability wise, the gas burner will win all categories except fuel mileage. Nissan may downgrade the towing capacity on the gas, to save from canibalizing the more expensive diesel, but that 5.6 is going to pull stronger. Fuel mileage will be a wash, because of the higher cost of ownership of the diesel. I can't wait to see the inevitable head to head.

I suppose I should update this thread too since we have new info on the gas.

Price: Gas is $5000 cheaper across the board. That is about $5200 with taxes. If you are finnacing, it will be even more.
Advantage: gas

Payload: Nissan was nice in keeping the same GVWR. The 5.6L gas gets a 500 lb advantage.
Advantage: gas

Towing: The Diesel gets 1000 lbs of extra towing, but it can be hard to use with the low payload especially with a goosneck.
Advantage: Diesel, but only with bumper pull.

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

MPG/ Miles per $: 500 lbs is a big advantage for the gas. Also, the 7-speed should help and the truck runs on 87 octane. Should be close, actually.
Advantage: ?

Depreciation/ total cost of ownership: Not sure that there will be much difference hear especially with modern diesels. Also, no return on extra money paid for taxes, interest of higher price.
Advantage: tie

Head over to TFL for a look at the new gasser. Real world unloaded MPG is looking to be better than the diesel. Diesel might still be better as far as xmission durability, but those customers will look towards 3/4 ton.

The new gasser XD is looking to be a big winner. If ford doesnt make significant improvements to economy and power of the 6.2L, the gas XD will bite into their F-250 sales in a big way.
 
#14 ·
Their real world testing at 70mph gave them 18.X mpg but I get over 21mpg in my diesel XD with the cruise set to 72mph. I average 17.4mpg with city driving according to the computer.

The diesel gets better fuel mileage unloaded and definitely should while loaded as well. The diesel will (should) last longer as well.

That 21.1mpg was when I got on the interstate, set the cruise, and reset the system and drove about 30-35miles at 72mph. That's with a full tank of fuel and my wife in the truck with me.

The diesel should also depreciate less. I'm basing that off the prices of current used diesels by Ford, Chevy, and Ram/Dodge.

We will have to wait until both trucks run the same route with the same driver. TFL got about 17 mpg running the same speed and distance but it was a different location.

@footloose - Keep in mind that these guys reset the computer before they accelerated. In any case, they should be close.

@sheanut - not sure why the 3.5tt is more of a truck engine if they used versions of it in the Taurus and a bunch of crossovers. Niether were chosen for the Super Duty so its hard to say which is more of a "truck engine". Personally, I would like to see the 5.2 voodoo in an F-150. Sure it revs to over 8000 RPMs, but the torque comes in relatively early and runs flat across. Oh, and it sounds nasty as well.

Yes, they did reset before they accelerated but that few seconds really should not drop their mpg by -4 over an 80 mile trip. However, I did my test here in Florida and there really isn't any hills.

Diesels have always been known to get better fuel mileage than the counterparts and I see this truck being no different. Diesel trucks weigh more but they run at a lower RPM, with more torque and use less fuel in the process. The same holds true in a car. Look at Volkswagen and other vehicle makers.

This thread will not turn into a flame war if everyone is unbiased and mature.

Nothing is for sure - see 6.0 and 6.4 Fors resale value vs gas.

The dynamic of the XD will be alot different than the HD domestics.
5-10 years from now, there will be about 100 HD domestics for sale for every 1 diesel XD. Many of those domestics will be selling for equal or lesser value than what the XD owners will want. In that time, the diesel XD will be seen as an inferior 3/4 ton with far less power than trucks like the 2017 Super Duty.

The gas XD will be viewed different I think. It will be seen as a superior half ton.

The only pro to having a diesel between the 2, is a very marginal increase in gas mileage. That slight blip in the radar isn't going to recoup the cost of diesel ownership, or the premium diesel price. As far as pulling goes, I expect the gas burner to be on par with the lighter GM 6.2 1500, up the Ike gauntlet. Even being a turbo diesel didn't help the XD out pull the NA 6.2, and the XD barely squeezed out better fuel economy. The only reason the XD is getting anywhere near the big 3 diesels in hwy fuel economy, is because of the Aisin ' s .63 final drive. The XD doesn't have the power to hold that gear in any uphill situation, so any uphill pulls, even small rolling hills, will be a lot closer in mpg than people realize. And as far as resell values go, if you bought a Nissan truck as an investment, or any vehicle for that matter, you bet on the wrong horse.

All good points imo. One thing I really don't like about the Ike test, is they don't use the same driver for every truck. I know they all play by the same rules technically, but they all drive slightly differently. and by their "rules", an 8 minute time should be the best a truck can do(60mph for 8 miles), so when they run 7:30 in some cases that means they were doing 65-70 in some cases(towards the lower end of the hill), which help create more momentum for the steeper grades. I think the biggest take away from the Ike test isn't necessarily how the trucks time is, but how it handled the load and how many times it up shifted and then had to downshift again.

In my truck life (gas and diesels), it usually boils down to operating expenses (fuel, tires, service, repairs). You can get most of the initial cost back on sale so that's a wash. Having said that, my diesels usually cost more to operate so they make sense only if you really need them. I would be most fleet guys who analyze this come to the same conclusion.

Resell is all relative. For one, to the informed, modern diesels don't have the reputation of being die hard, like the 7.3 or 5.9. In fact, a 150k diesel could have have all sorts of issues waiting under the hood. Dpf's have an expiration date, as do many other parts that are known weak points. Everyone knows that guy with a diesel that spent more time talking to service technicians than driving his truck. So, as the public becomes more aware, that resell value will diminish. Also, resell values vary by make. You can find 6.7 Ram's all day long, for cheaper than a GM with a 6.0 gas burner. It doesn't matter how much you spend on the Ram, it still has the lowest resell value. Demand drives that value. Right now, it is way premature to assume the XD 5.0 will even enjoy the same value as the cummins Ram. Buying the diesel doesn't guarantee resell value, especially over a powerhouse gas engine. Remember the 90's before diesels hit their prime. The GM 7.4 and 6.5 would be a pretty good example. The 7.4 destroyed the 6.5 in every category but fuel mileage. It was considered the "premium" engine.

Pickuptrucks.com has a good first drive of the 5.6 gas. They also compare the torque curve of the new 5.6 to the old 5.6 The new one is much flatter and doesnt drop off as much after peak.

What I'm not sold on is the 7-speed. It is more of a 6-speed PLUS since 6th and 7th are so **** close together.

Let's compare the effective ratios of a Nissan 7-speed with 3.36 gears to a 6r80 with 4.10 gears:

7-speed : 6r80 1st - 16.9 : 17.0, 2nd - 10.7 : 9.6, 3rd - 6.8 : 6.3, 4th - 4.7 : 4.7!!, 5th - 3.4 : 3.6, 6th - 2.9 : 2.8, 7th - 2.6 : xx Ummm..... yeah, not much differance.

In fact, if you were to put 35" tires on your XD gas, 6th gear would then be VERY close to 7th gear on a truck with 33" tires.

Back in the 4-speed days, regearing could make a big difference in performance. With 6 or more gears it is usually a waste of money unless MAYBE you bought a truck with very tall gears and wanted to put 35" tires or bigger on. Even then, it would just be easier to lock out the top gear like you can with the Ford and save a lot of money.

Changing tires or rear end ratios will not change how close together 6th and 7th is.

The top 2 gears on the 8-speeds from GM and RAM are not nearly that close together:

Nissan: 1.00; 0.86; 0.78
Ram__: 1.00; 0.84; 0.67
GM___: 1.00; 0.85; 0.65
