Diesel coming back!?

[Grayhound]

Saw this, use caution when watching this guy. I’ve been guilty of buying into some of what he says without doing my homework, but this would be exciting!

Serious question: Why are you still watching their videos, if they've proven to be full of shit?

I don't mind a little speculation, if there is sufficient evidence to back it up, but most of these videos are just people jumping to big conclusions based on a miniscule sliver of information.

There are tidbits of truth that I’m able to garner through watching his videos

That guy is 85% Bullshit 15% waste of time.

I'd love to see them bring back the diesel, preferably with compatible (but better) emissions after treatment equipment. I'm about to roll over 80k on mine and have some worries about parts availability down the road.

Worst-case scenario is we end up counting on Chinese manufacturers making knock-off parts.

Hell, I ended up forking out ~50% more for a turn signal LED ($335!!!) to get OEM instead of Chinese knock-offs. That's for something that's not even part of the engine. And yeah, I just checked where it was made ... Mexico.

zero information out there about the return of the 3.0 Line up. id bet all the money this guy is full of poooo

Its coming right after the 5.7

I just wish that the EPA rules weren't so one size fits all. Instead of making every diesel engine meet X requirement no matter the size, they should allow smaller diesel that replace larger diesels to emit more than the regulation, as long as it does not emit more than the larger diesel it replaces.

Cummins proved this worked back in 2020 when they replaced the 6.7L in a cab over box truck with a 4.5L diesel and a electric motor hybrid setup. They had the 4.5L hybrid truck perform side by side with the 6.7L truck on the same routes between San Antonio and Columbus. They saw a 65% fuel reduction without any negative effects to performance — the 4.5L actually having quicker acceleration. The electric motors assisted on takeoff and and hard acceleration while the diesel only operated at normal highway cruise when hp demands were low.

It would be nice if we could have a 225rwhp/375rwtq 2.0L diesel, similar to the one in my BMW, that is allowed a little leeway on PM and NOx limits (just as long as it doe not emit more than the 3.0L diesel it replaces) combined with an hybrid giving it another 134 hp like the one in the 4xe. There is not doubt you could see at least mid 30 mpgs on the highway with plenty of power. But EPA rules force the same emission requirement no matter the size of the engine.

You make a valid point in net reduction being more important than a one size fits all standard.

i get the standard should be easier to hold but everything is a case by case anyway. So looking at net positive impact doesn’t seem as tough in practice as it may seem at face value

I speculate v10 with 10spd, d60 lockers.

It was introduced to the EPA for the upcoming 2027 emissions, but they rejected it. Even though 4.5L hybrid had significantly better net emissions and fuel economy than the 6.7L, they still wanted the 4.5L diesel to meet the same restrictive standards.

The problem with having the same standards is that the emissions system causes a lot of heat, especially under heavy load. If the emissions were laxed a little to create less heat, then you would be able to crank out more power from the smaller diesels without any significant side effects. Yes, it will emit more than the current standard placed upon it, but it will still emit less than a larger engine that it can replace. Heck, even if it emits the same, the fuel economy savings aspect would still be worth it.

This is one reason why I hate the bureaucracy of the EPA that only cares about meeting an emissions number and not about any net emissions or the secondary emissions(like the creation of the DEF industry) that it takes to meet those numbers. But many people see the EPA as god and if you don't think the same then you must want to go back to the days when there was a haze over every city.

Small disagreement, some see CARB as god and if Ca uses EPA compliance it will
“Make California Smoggy Again”.

Therefore, most all vehicles are produced 50 state compliant ….. CARB must be god.
