Mopars new turbo 6 cylinder Hurricane's appear to be very impressive

I think that is what most of us need in our trucks.. One of the reasons for going truck for me in getting a truck vs getting a sedan or a SUV was the sheer simplicity of it. This hasn't been the case of a while now and it seems that the trend is not going away. More complexities are coming our way due to emissions standards, etc.
I always felt that even though the HEMI has some minor issues, these could easily be resolved with the right maintenance and the engine was simple and powerful enough.

First it was who was getting the largest payload and towing. Ram took that for a while. Then it was who had the highest horsepower.. Ram took that for a while. Now it is who has the best EPA and fuel economy without compromising rest. I'm guessing that Ram will take it with this (at least on paper).

I'm wondering if the Ram 1500 classic will be getting this I-6 unit as well. If they are keeping the HEMI for those, you're going to see an increase in sales for the Classic.
I got a 6 cylinder MC, prefer the V8 in my truck, if I wanted a straight 6, would look for an old Chevy or Dodge from early 60's, LOL. (Not the Ford 300 6, POS)

Guess with all the changes and alleged upcoming doom of the Hemi, gonna keep my Hemi "Long Time".

I’ll never understand why they didn’t just turbo the Pentistar.

Carbon Credits. You nailed it. That’s what it’s all about.

The guys that think they got a 3.21 rear end for fuel economy. noooo…
Emissions. No more complicated than that.
Got the 3:21 because was wat was in truck when bought, LOL, would prefer 3:92, but the 3:21 suffices.

This video has a bit more info for the Jeep application, and is saying the standard output will have the same octain requirement as the current 5.7, and is a $2,000usd upgrade from the Hemi. https://www.youtube.com/watch?v=z7-dDV_lolM

The new Jeep options have worse mileage when towing compared to the existing, so it will be interesting to see how much loading it takes to loose the fuel economy advantage for the RAMs.

Both the 6.4 and H.O. in the Grand Wagoneer use premium, and I'm curious to see if we're nearing the point RAM will call for Premium to get better emissions and mileage numbers. I've worked with a few business expecting to get carbon tax credit if/when switching octaine lowers use/emissions.

Those twin turbos must be mighty pricey for 2 less jugs. Might be a profit gouge as well.

Pricing seems to be in line with the range of alternate engine choices, be it RAM's EcoDiesel or Ford's other option.

That's exactly what the intent of the new I6 is. It's small, turbo'ed, and will shortly be hybridized as well.

It does seem surprising at first to see a manufacturer come out with a "new" engine at this point, but the hemi was released in 2003 and simply won't last (in terms of MPG and emissions) to 2035.

But I'll believe 2035 when I see it. To me that date is far too optimistic.

In the meantime, we'll rely on solar flare collectors on our rooftops for thermonuclear propulsion.

The potential failure points on these will make the HEMI lifter issues look like a walk in the park. Having owned several Turbo charged vehicles, by God I wouldn't want this in a truck. The only inline-six I would want is a Cummins.

That fact that Ford still doesn't use the EcoBoost in their HD trucks even after 7 years of development speaks volumes. However after owning both 5.7 and 6.4 trucks since 2003 I have never been overly impressed with the low end torque these engines make. Usually when I'm towing heavy (or even moderate) loads up hills it feels like the engine is always screaming. So I am intrigued over the possibility of a well built turbo I6 as an option. Anyone who ever owned a old Ford or Chevy I6 in a truck knows how well they haul. Honestly, even better than some of the V8's of their era.

All that said, I really wish FCA had just released a 426 Hemi in the HD trucks as it probably would have helped the torque problem considerably. Oh well.

I've been watching a YouTube series were a guy tears down broken engines. The direct injected engines (even without boost) have very carbon uped valves. The new six with twin turbos is making a lot of boost 20+. I can't imagine how much positive pressures it makes internally with blow by and such. How are they planning on keeping intake and valves from gumming up with carbon. What maintenance are owners going to have to do to prevent/fix this issue. You can only put in so many catch cans. Maybe need to do a IV drip of sea foam lol

The 2nd gen Ford 3.5 Ecoboost has dual fuel injection from 2017 on. They added a small port injector to each cylinder to keep the combustion chamber clean.
As dire as all this might seem at least Stellantis didn’t go straight from the Hemi to EVs, that would have really sucked for those of us who plan on resisting until we’re forced to buy into it.

Well, spark-ignited engines never produced a lot of low rpm torque. And the Hemi's claim to fame is high rpm horsepower for racing. Hardly an appropriate fit with trucks except for the newish fad of truck racers.
The whole point of siamese valving is better high speed breathing. Hence Richard Petty's wins.
Nothing special about 426 Hemi except more displacement. Engine Masters showed how the 440 kicked the 426's a$$ up to 5,000 rpm.
Any of you running 5,000 rpm routinely? Hemi is nothing more than a marketing gimmick outside of racing.

This is my point. I wish this new engine had duel fuel injection. Can we learn from others mistakes? And not just repeat other's before us. I love the numbers this inline 6 makes but with the boost they are putting in the engine they are going to have carbon build up problems no doubt.

+1

GDI engines have no business with only a direct injector when in stoichiometric loads. It defeats the point of having a direct injector, which was always intended to be IN ADDITION TO the port injector. Instead, all the car makers cheaped out on a sole direct injector, with all the corresponding problems (LSPI, carbon buildup, short oil life, etc. etc. etc.).

They do have a 426 Gen 3 Hemi,it's called the Hellelphant,lol. They could have easily taken the 392 out to 422 or 426 with a longer stroke,it's a pretty common combination these days,you can even take the BGE block out to 454 cubes if you want. The fastest naturally aspirated 1500 was Rick Spillmans truck with a 454 cubed BGE in it.

My dad always like the biggest small blocks - they were the most efficient use of materials and were priced as such. While gas mileage wasn't good, it wasn't horrendous as it was with the big blocks. So, I shared his enthusiasm, all the more so getting my mechanical engineering degree, that app. 400 c.i.d. V8's were the 'ultimate' engine for most of my moderate-load uses. Even with all the changes in technology and emissions, it still hold true to me.

God knows it would cost an arm and a leg fueling the old 440 big block today! I guess my point is the Hemi doesn't do anything for me literally, and figuratively. It's just marketing crap. And you really gotta watch it boosting sparkies since we all expect 200,000+ miles out of them today.

If diesels didn't have to have all the exhaust aftertreatment crap, I might have kept buying them.
