In light and medium duty operation . The DI gasser is superior to the Tier IV Dieselim 2018.
We keep having people here stuck at the 1975 level of diesel and gasoline technology.

im 2In light and medium duty operation . The DI gasser is superior to the Tier IV Diesel....


Substantiating facts, please? Does a DI gas develop it's torque at 1500-2400RPM like a diesel?

With the complexity of modern emissions laden diesels, it would take a real serious situation for me to even consider one. I get enough grief from my heavy truck commercial diesels that I sure don't want one in my pickup if I can avoid it.

While I hope that this new 3L diesel is a great hit, if I was inclined to consider it I would wait it out for a couple of years while they get the bugs worked out of it. Problem is, even that diesel doesn't change the dynamics. It is still a 1/2 ton pickup. My 2500 6.0 gasser has significantly more capability than any 1/2 ton running around, and this diesel 1500 will be no different.

Some would argue fuel economy of the diesel, and that could be true. But right now, E85 is going for $1.70 in my area, and diesel is going for $3.15. I get about 11-12 mpg average on E85 in my 2500. For a diesel in my 2500 to break even, it would have to get 21-22 average. Possible, but not probable. Remember, that is average.... city, rural, highway, etc. The numbers work similar for a 1500, just a little better since it is 1000 lb lighter out of the gate. So while the new diesel 1500 might be able to pull off some nice fuel economy numbers, it probably will be in the range of the other brands.... about 5-6 mpg better across the board compared to the gas versions in the same pickup. That isn't good enough for me. I would much rather have a flex fuel gas engine. For a diesel to come close to matching my actual cost per mile on E85, it would have to get a minimum of 75% better fuel economy at today's prices. And even better than that for any hope of recovering the initial cost of purchase. Not going to happen.

Seems like more of a status symbol / social statement to me than any appreciable benefit of getting the diesel in the 1500.
What you say is logical, but remember that 99% of personal truck purchases are emotional!

Why does that matter, when one can use gearing to get the power in the speed range that is desired? Notice I said "power", as that's what moves things! Or buy a Ford with 3.5 EcoBoost; that has a monster "area under the curve" for torque, starting very low (full disclosure, my daily driver is a Flex with that engine.)

For me it's personal preference to not endure the constant downshifting required to get the drivetrain into the area to sustain speed on incline, I've driven the ECOboost towing the exact same trailer as an EcoDiesel, the gasser downshifted continuously on the same drive as the EcoDiesel, so it's how pleasant of a drive - but hey to each their own, if you like hearing it rev and roar, go for it and save your $$ up front. Choices, that's what it's about, and I'll make mine for different reasons. If it costs me a little more up front for a (what I consider) more pleasant driving experience, that's my choice.

Now, on complexity, has anyone really looked at what's involved in a FlexFuel - really about the same as a SCR fitted diesel, just different, how many of you balked at having FI vs. carbs in the past, now it's a given, and with DI, it's even more complex and relatively comparable to a common rail SCR diesel. Yes, the new SCR diesels are more complex, but not compared to the alternative gas, only to pre-tierIV diesel. YMMV

Don’t worry it’s not going to be long before all gas engines will have Gas Particulate Filters. They are already on some new cars.

Thanks for that info. Now I am more convinced that I will try and make sure the vehicles I have currently be the last ones I ever buy. Getting older does have it's advantages.

I own a 1st gen Duramax as my daily driver, for me at the time was buying a truck with all the power I need and lasting me many years. Nowadays I can't justify buying a new diesel truck, when you compare a gasser to a diesel, between the initial cost and fuel price differences there would be no way to recover the overall cost difference of owning a new diesel. This would be more revellant if you were one to purchase every few years.

Some folks have a good reason to own one, other's just want one.

Like an old buddy of mine would say "That's why they make chocolate and vanilla"
