For many people, you could put a 4 cylinder in a Ram 1500 & then put a stereo recording of a Nascar V8 in the cab of the 4 cylinder vehicle & they would be happy as a Clam in hot butter.
Isn't that what Ford did for a while :)

The rest of us work our trucks

As much as I love the sound of a V8, the arrangement of two banks of 4 cylinders in a "V" is an abomination in physical dynamics. An I-6 is dynamically superior in virtually every way. And since its Direct Injection, it can use higher forced induction without the old pre-ignition worries. It's going to produce more HP and TQ than the 5.7 Hemi and do it smoother without beating itself up. I think it's going to be a great engine after the initial wrinkles are ironed out and many of the V8 stalwarts will come to see the light of inspiration that this engine will bring. I'll miss the beautiful Hemi exhaust note, but that's about it. :D

And like somone else mentioned. I'm glad Stellantis is giving us this ICE option for a few more years instead of jumping "all-in" to EV's

Every new “complexity” engineered into these newer vehicles, be it cylinder deactivation, direct injection turbo charging etc. bring with it expensive problems. They should just fix the multiple problems on the hemi and keep it. Small block Chevys were built for a lot of years

Can you be more specific about these problems that Chevy has nothing like? It's no skin off my back if you go back to Chevy. But I'm curious to know what problems you've had that seem to far outweigh any problems people are having with Chevy.
Chevy has its own problems. The 4-8 cylinder deactivation is a problem, my
brothers 2018 Silverado puked the valve train at just over 100K. I have a
2018 Yukon with less miles and I installed a Range disabler that stops the cyl.
deactivation, just runs on 8, and the mileage has increased. It just goes in the OBD port, very simple, around $220. or so.
I now see that they make one for the Ram 5.7, that may be a good thing for someone looking longterm.

What you should be looking at is, the Brake Mean Effective Pressure for the engine or any engine you want to find out how much stress a engine is under. This is a calculation that will give you an idea as to the longevity of the engine, a low BMEP means that the engine is under less stress than an engine with a high BMEP.

You can look up the calculation from numerous websites that will even do the calc for you but if ok with math here it is:

BMEP = (Torque x 75.4) / (Displacement x PPR)

I wouldn't stress over the Tech that will be involved with the new Engine, simply because tech is getting improved everyday. Issues will be plastic bits as per any vehicle, you could ask RAM not a Dealer what is the design life of the new Truck.

Every manufacturer designs their product to have an economical life, thats were the cost of maintenance becomes greater than the replacement cost. Just look at BMW or Audi nice cars but you don't see many 15 years old or greater.

As for ICE's they are going to be around for a long time, main issues are Charge time, Battery Life, Plug adaption currently 3 types, the reliability of charge stations and Towing loads. Stellantis has already said it will continue with ICE development for the future.

Will the hemi pass the tighter epa regs coming in the near future ?

I have seen so much about this upcoming engine. My main wonder isn't will it be a good motor, and make for a long lasting vehicle. I just want to know, how is the community going to receive/is receiving the death of the v8? What do you think about the future of CDJR products with this being the new "big dog" in town so to speak?
I'm gonna show my ignorance on this one...but I do have a POV on it. First, I haven't even kept up and am not familiar with the "new" I6 (been busy with the project truck). Second, though, is that I've owned a long succession of Ram (before they were called Ram) and Jeep products, all of them used to the draconian max in 4x4 environs. I think my point is that, if the new I6 reflects the design and QA elements of the long-time Jeep I6 motor (that you can't get anymore), then I'm in. That 4L MPFI I6 from Jeep would run forever, was (IMHO) a blessing to work on, and maybe has spawned a new/advanced generation? Oh...and if I'm all wet...a la Roseanne Rosanadana...never mind! :cool:

No matter how you attempt to get more out of a six-cylinder engine, it's still a six. Blow the turbo halfway to your destination towing 10,000 pounds and your SOL. A six is a six is a six. Sort of like lipstick on a pig. We all know how that ends.

I'm not sure the point of the motor if it only gets 1 or 2 mph over a hemi and isn't the current administration mandating vehicles (fleet wide) will have to get 40mph by 2026.

I wonder when the day will come when I have to pay 2500 per year to the government for the privilege of owning and operating a hemi?

Maybe the point of the motor is to offset the fines Stellantis incurs or reduce the amount of carbon credits they purchase because it can't be the mph efficiency.

In a gas truck i am a v8 fan myself, but a Inline 6 is a different story Produces lots of torque at low rpms. I mean the cummins is a inline 6 and is a power house. I think they are going the right direction inline6 vs v6 at least. It might not be a popular engine in a truck but on a jeep platform it's going to be killer.

Inline 6 is about 430lbs and the hemi is about 600lbs. 170lbs difference is a lot of difference hp to weight ratio.
Yeah, that's a lot. I wonder if they couldn't have developed an aluminum block instead of cast iron to keep the weight down tho?

They did. And still do. But how many years were they underpowered garbage? And the technology didn't sit still. I've driven more GM vehicles than anything, and the modern LS motors are *phenomenal* motors. Can you imagine if they were still using TBI 305s? Or maliase era anythings? The market would be so far past them that you couldn't give them away.

The flip side is we did a lot of work with straight or slant 6's back in the day and the by-todays-standards vastly underpowered V8s. We just expect so much more from trucks today, and the trucks have delivered it.

I mean ford is still putting the 5.0 in the f150s last i checked. i would love to know the numbers. But the ecoboost has been out for 12 years , and they are STILL offering a v8 at a premium over the 2.7 EB or 3.3 v6 base. I would be, its still a top seller amoung build and pricers
Not very many though.
If you want a 5.0L anymore it's pretty much a custom order according to my Ford lovin' cousin...

My biggest fear is the G-men saying " screw your HP and torque #s" and sending us back to the 1980s when most trucks had about 180 hp...
If they can scavenge a couple of extra MPGs AND make more power to the wheels I say go for it...

Those electric charging stations are far from perfect

The news is now reporting that people that own a Tesla have been warned not to use the fast charge setting
Using Fast Charge is burning up the Fancy Infotainment System

Nothing to do with the stations.

Tesla is recalling about 130,000 vehicles (of over 2 million sold) across its U.S. model lineup because the touch screens can overheat and go blank.

The recall covers certain Model S sedan and Model X SUVs from 2021 and 2022, as well as Model 3 cars and Model Y SUVs from 2022.

Tesla is fixing the problem with online software updates.

A few MPG multiplied by a few hundred thousand trucks adds up when your goal is a 50% reduction in carbon emissions by 2030 and to be Carbon Net Zero by 2038. https://media.stellantisnorthamerica.com/newsrelease.do?id=23660&mid=1

Stellantis is claiming the standard output Hurricane will run cleaner, have a 11.8% increase in fuel mileage, 7% more horse power, and 15.8% more torque in the 4x4 Jeep Wagoneer, unless it's towing - where they expect a 1.5% reduction in mileage. Should be interesting to see how it gets adjusted for the 1500.

I am in agreement with the mechanical engineer. Though I am an electrical engineer I have supported these production lines and came to the same conclusions. An in-line 6 can be a very reliable engine but not for heavy uses. (Outside of the diesel platform) Boosting add critical stresses that are not reliable for the mileage expected. I too am a V8 guy and really don’t give a shheeeeeet about mileage. I want RELIABILITY above all else and clearly the American Auto Industry has been far behind in innovative products that are both appealing and reliable. Poor Mary Barra looks exhausted and if anyone has not noticed so are literally dozens of CEO’s and top executives of major corporations. Americans have become victims of their own successes and arrogances. I won’t be around in 2040 and what been done to the planet is irreversible now. God help us all.

I remember when I-6s were the norm in trucks from the 1/2 ton up to 2-1/2 ton series. I hauled countless loads of grain and livestock in a 1955 Chevy 5500 w/a I-6. The truck has been sitting at the farm for a decade but, I have no doubt it would start again with fresh gas and a jump.

I really like my Hemi, but am good with trying the I-6. It may disappoint but I’m not opposed to giving it a chance.
