Should Stellantis Build a Smaller HEMI® V8?

Should Stellantis Build a Smaller HEMI® V8?​

Exploring a Modern HEMI® V8’s Potential in Stellantis' Lineup Amidst Shifting Industry Trends...​


1732303366116.png

The push for electrification has transformed the automotive industry, yet internal combustion engines (ICEs) remain a cornerstone of vehicle sales. Companies like Ford and General Motors (GM) continue to refine their V8 engines, demonstrating that innovation in ICEs still has a role in the modern market.

 
Well you can replace the torque converter with Motor, A smaller battery than EV fits easily in the floor pan. You take your 550hp and add another 150. You are at 700. You have hellcat level power and ability to daily drive 30 miles on a commute with no fuel used.

Take my money
I agree, "Take my money"!!!!

This will be interesting to see how they utilize this transmission with the new models.
 
"3.8-litre V8 engine is a perfect representation of Maserati’s performance tradition; it’s an EURO 6 homologated engine combined with a 12% reduction in emissions and consumption versus the previous EURO 5 engine, thanks in part to the Start&Stop system. The engine produces 390 kW (530 hp) of power at 6,800 rpm and accompanies this with 650 Nm of torque from 2,000 rpm to 4,000 rpm. This maximum normal torque figure can be automatically overboosted to 710 Nm from 2,250 rpm to 3,500 rpm."


The Heads were popping off, well they still are on the Iron block. not uncommon as so they are also on the Coyotes.

The Coyote under performs other than in low volume Halo models where they can manage the engine failures or blame the owners. GM is putting some awesome bespoke engines in it very exclusive and pretty rare Vette, other than that they have move on.

The Truck GM V8 underperforms even the base Hurricane at 5.3L EcoTec3 V8 engine 355 hp 383 lb-ft of torque and so does the Coyote Ford V8 400 hp 410 lb.-ft. of torque,

I am sorry I DON' GET IT..... exactly why do we want a heavier more complicated and lower power engine for our Pickups and Volume performance Cars?

HEMI, that there got a HEMI ..... AWESOME marketing maybe too Awesome.

Management has introduced a new line of engines that outperform the previous engines and it seems some cannot get over what it isn't, not what it is.

Even a Bespoke Halo Model V8 would only slightly outperform the potential in the new I6, and would purely be marketing.

We keep going around on this, but the same reason the Cummin beats the GM and Ford .... no on in the HD world wishes there Cummin was a V8. Basically, one is in the same world when we are talking about high boast and DI, the internal pressures keeping the valve train intact is a big deal. It is geometry issue the I engine configuration gives you room to secure it in a way that is impossible in a V8. Not to mention that it only one and I6 is perfectly balanced while a V8 is not.

Continue to get no acknowledgement on this other than we want what we want even though it might not make sense..... I don't know if anyone else has ever had to get a ROI approved for a multi-million dollar project, I have.... Not to mention to write one for multi-BILLION dollar project, I can't even imagine.

So no offense to anyone here and if I sometimes come off harsh or direct that is the Engineer in me. But is dang near impossible to get Project approved on its just what people want, there has to been hard factual reason documented why and with none of the technical solved for a mass production engine. I love V8 also but when I look at the engineering challenges and the performance realities, I can't figure out a viable ROI on it. Seems to me the best money spent is on marketing.

Evil Management just spent a crap load of money on engine that benchmarks and exceeds all the Volume offering in world, and now you have to go back and ask for money for something less, so it can be a more fragile configuration based on the old solution? It just has to be a V8 and just has to be marketed as a Hemi .... is not a ROI.

I know they are going to go bankrupt without it.... that is not a ROI either.

I do look at GM and Ford and what I see is that they have moved on to low displacement Turbo engines and Electrification asside from Halo models. I see they offer lower power legacy V8s as legacy option on pickups.

With the EPA fines Mopar moved on, because they were inverted on the volume and didn't have the capacity or offering until now. Maybe they can do the same with Trump administration but it still from pure numbers perspective make little sense.

Don't just write fanfiction.... try to write a viable cost justification. It might be based on marketing on a V8 as that is the only path I see, not technical.
600 bucks for a 5.7L
How's that for cost?
 
As someone who owned a Dodge Avenger with the 2.4 liter "World" four cylinder, let me add a few thoughts. I could live with the exaggerated horsepower claims. The sedan was also fuel efficient for its size. The Achilles heel for the World Motors engines was the cheap Chinese plastic parts. My Avenger was plagued with mysterious cooling problems due to the oddball dual thermostat arrangement. The plastic radiator cap housing would warp and let the coolant pressure drop unexpectedly and at one point decided to simply burst. (It happed while I was backing into a parking space at work, so I was able to immediately shut the motor off.) My engine was unharmed, but my bank account was severely damaged fixing everything.

I haven't really examined the newest four cylinder GME and inline six in detail, so I don't know if the practice of using cheap Chinese plastic parts for the cooling system's plumbing continues. I heard it does. Ram and Jeep ask too high of a price on the vehicles which use the Hurricane Six to then use cheap plastic parts of questionable durability.

Quite frankly, I would be wary of any all new V8 developed during the reign of a few Penney pinchers. I don't care what the specs are.
 
No cheap Chinese parts, Injection molding is more expensive in China than the USA. The machines are slower, the resin, is more expensive ..... and labor is irrelevant because of automation, only saving is in the secondary processes.

Most Metal replacement is not for cost be for weight, using engineered resins has taken a bit of learning curve but it is needed for the future. The Italians are the leaders in this and have piloted programs that started out lower volume and exotic cars that find the way to volume vehicles.

Living in MN one would be testing the lower limits of the resins cold fragility. Design, material selection, and processing would be reasons for failure. During the PE ownership there was a lot of false economy around molding. A well designed component or properly tooled component is not more expensive... sometimes the tooling is bit more but that is pennies of the volume.

Honestly one of the issue is sourcing the tooling in America instead of Asia or even EU. You send more in the USA to tool than anywhere else in the world including Austria (best tooling hands down in the wolrd) so you get less content and therefore slower and less intricate tooling. So it is backwards, There is really no reason for American tooling to exceed Austrian, Italian, or Portugese. NONE other that margins,

So if one builds in Italy or China the capacity you get better components and if molding in USA better material and process quality.

But what do I know about the subject. Chinese tend to run to hot and damage the molecular chain,
 
popped heads are awesome.
Why do you continue ad nauseam with lies? It’s embarrassing for you…

Hemis don’t “pop” heads. They don’t have head gasket issues. They have almost no issues overall. Great engines.

Every attempt you make to discredit the Hemi and combustion in general is ignorant, foolish, and a pitiful reach. You should be ashamed pushing such lies
 
More thinking out loud. Seeing the article here at Mopar Insiders on advancing the Ramchager further up on the priority list, leads me to wonder if a V8 could be designed for hybrid use. The Pentastar V6 is offered in an Atkinson Cycle version for the Chrysler Pacifica PHEV and there is speculation there will be further modification when used strictly as a range extending generator in the Ramcharger.

I could see a V8 built along the same space saving principles of the Pentastar for use with mild and full hybrid models as well as a range extender used for an ReEV. The supplier chosen for the blowers when the Hellcats were introduced was also the same supplier for the blowers on a Miller Cycle Mazda V6 that brand offered briefly in our market. My fantasy power train would be a small displacement Miller Cycle V8 connected to the ZF 8-speed hybrid transmission. The V8 could supply power for Ram HD trucks if they decided to offer a ReEV option.

Why would you want a multi-head unit to drive a generator... Packaging and marketing? Honestly a small 4-cylinder diesel would be an awesome option.
