[QUOTE=Desert Don;19906859]
It's clear as day to anyone paying attention that the cost to the consumer of utilities-gas, diesel, electricity, or natural gas, does not in any way factor into the decisions of the people in charge. They have an agenda and they will be sticking to it no matter the burden to the commoner.
However, physics still applies to moving a load and if diesels are eventually forced from the marketplace an alternative will be needed. Even a future (far into the future) solid-state or metal-air battery won't pull 30,000 pounds for 500 miles. It's probably physically impossible to fit a battery big enough into a F-350 sized vehicle.
It's also possible we'll see DPF diesel-type emissions equipment on gas engines in another decade or so.
Incrementally, we'll probably see the cost of the diesel option increase faster to the point that more heavy haulers opt for the gas option.
There is a story I remember from my father in law about the v10.
He is a Ford mechanic and said he was in Michigan for some training, I don't remember what for, and got to talking to an engineer about the v10.
Engineer said they actually tried turboing a 6.8 and it out performed the diesel of the time in every way except mileage, and that was only marginally worse. They scrapped it though because the profit margin wasn't there like the diesel.
Now that could be completely untrue, or completely 100% accurate. Who knows. But the way the 3.5 runs and people say it feels like a diesel pulling, I'm sure a twin turbo v8 would kick ***[/QUOTE]
Yup for sure, especially when hooked to a big load. You will need about a 1/2” diameter fuel line to feed the beast. Seems no one remembers the sticker shock they got when they first hooked the 3.5 V6 Egoboost to a good load........went something like OMG, these things like gas when working.
Remember the old 534 Super Duty V8? 4MPG maybe on a good day. The old IH 549 V8? About the same. Yup, technology has improved a bunch, but I will lay long odds that big gassers will still like gas.......LOTS of gas.

I highly doubt this will end up anywhere near a Super Duty. It just won't have the expected durability and lifecycle. The 7.3 was designed from the ground up to be a durable, low cost engine. As-is I wouldn't expect these engines to have the life of a PSD and increasing the BMEP is only going to make that worse. It's a fraction of the cost of the PSD though and that's a reasonable compromise.
I'm not sure what turbo coatings are though. Can anyone elaborate on that? Typically for forced induction applications we change ring gap, compression ratio, camshaft profiles, and sometimes the intake to exhaust valve area ratio. Ceramic coatings have been investigated to improve thermal characteristics, but aren't common for normal production vehicles. Any of the other coatings I'm familiar with have their place on either naturally aspirated or forced induction applications.

I can see stupid laws pass that require you to be approved to have a fuel burning vehicle (aka truck). Diesel will stay longer than gas as technology isn't there yet for storing enough energy to last a days worth of driving for commercial trucks. Once that is achievable watch out. Fuel burning vehicles will be quickly phased out. Next issue will be where does all this energy come from? Hope solar or another form (split H2O) energy is born or we will be paying through the butt to travel. Sure ... it may seem like we are doing something positive for our mother earth but I'm afraid we are simply moving the dirty part from our tailpipe to a power plant's smoke stack. Are planes going electric too?

I can see it happening. It would reduce the weight of the truck, which would benefit guys like me who work off road. It would eliminate DEF, it would be cheaper to operate and purchase and it would have enough torque and h.p. to virtually eliminate the need for diesel. It might even be operational on E-85. From what I've heard it performs well in a forced air system. I personally welcome the idea, hope we see it in the next year or so.

That riled me, but I held my temper as I asked, “What’s the matter with you?”

And that's just it. The horseless gasoline and diesel fueled carriages, dreamed up by imbeciles, experimented with by fools, that were eventually massed produced by Ford and that have now served us now for well over a century... are just that. History.
Considering the perceptions that people have today regarding the permanence of fossil fuels in transportation, mirrors the perceptions that people had in the past regarding the permanence of horses in transportation...
... it is evident that history repeats itself.

And those who believe lithium and other new age battery sources are plentiful are likewise foolish and never read the destruction these mining efforts place on the environment and likewise their disposal footprint! But hey, keep eating those healthy Big Macs as well.

I do wonder if there's a larger issue with Ford's expense for warranty repairs on the PSD. My local dealer told me that most work involves removing the cab. That can't be cheap. I'm sure the $10k price upgrade pays for a lot of that, but I wouldn't be surprised if they boost the 7.3 gas motor.

Chevy with their 6.6, old 6 speed and 3.73 axles is almost identical towing numbers as Fords 7.3 with 10 speed and 3.73s.
Long has there been rumor of Chevy bringing out a new big gas in the range of 7.4 - 8+ liters. Put that in a truck with a new tranny and lower axle ratios and Ford will have to do something

If not boost, Ford is at least working on something.
