The head of powertrain for Stellantis says otherwise and I think he'd have a better idea. That guy is just looking for clicks by making up fairy tales

That is quite possible.

I just thought he had some interesting food for thought. And I wouldn't put it past Stellantis to say one thing that could enhance today's sales and then turn around and do something else.

The true inside info was that the 392 was going to get bumped to 426 inches (just by using a 4" crank) and that was going to be the new 510hp engine but the Hurricane H.O made that and more, so they went with it. That same dreamer was saying a new hellcat was coming out in 2030. I guess just in time to compete against 3000hp EV's and stuff

At the current rate that the other car companies are reducing or stopping production of the EVs, The current build up of unsold stock, and the distain for the current governmental leadership, maybe some one at the head office is in charge of coming up with an alternative performance car to replace the HP EV car in order to " save" the company. It would be something the company would want to keep under wraps until they needed it to show up.

Head of powertrain came from American Axle but was wit GM for 23 yrs before that

Are Ford and GM dropping their V8's (and Toyota too) ?

To throw away six decades of HEMI V8 as a sales attraction and bragging rights at this point would be downright stupid. Only a foreign car company would do that. Foreign car companies stupidly put smaller, more efficient engines into a car and get away with it and then tried to sell them in the USA. In America we put BIGGER engines into a smaller car and kick the cr@p out of those little engine foreign cr@p cars. No replacement for displacement and a 4cyl or 6cyl turbo is just un-American. A HEMI-V8 with a supercharger now that's AMERICAN and not just my opinion.

I can see another 8 coming. This whole EV thing will last, but will take years and the "Mania" stage is now ending for it. Reality is setting in. SCOTUS may well end up hearing the "Mandates" and into the junkpile those will go. Would it be a hemi? I have heard doubtful due to combustion chamber design but others are much smarter. That and Dodge would probably be forced to take some sort of Euro design input just like they are for the platforms. Remember, this isn't the old Dodge.

I think you are missing a decade. First Chrysler Hemi was in 1951, that's 72 years.

Regardless, there was a l-o-n-g time between the Gen II and Gen III versions where Chrysler was focusing on crap wagons.

Oops, yeah that's what I meant SEVEN DECADES

I6. (Walter Chrysler loved the I6)
I4 Hybrid,
Balance shaft I3

We’re all really Peugeot now - so why not an opposed Twin?

If Ferdinand Porsche sitting in a French prison cell with plenty of time to think decided that opposed twin was the ideal engine for the masses, who are we to argue?

Sadly,
the two valve,
two spark plug,
cross flow cylinder head engine that was cheap to mass produce in Mexico
(Chrysler Hemi as modified by
Nissan NAPS-Z
and then Maximum Bob Lutz
and those two engineer brothers who quit GM due to a Lutz promise to let them design a 347 ci cylinder head that would outflow any 350 GM)
....has been murdered by liberal arts degree staffers in DC.

I hope a Moparts member buys the last new vehicle with a Chrysler Hemi V8 under the hood.

You cannot step in the same river twice as the water constantly changes.

They were getting slaughtered by fines, more on the 5.7 than anything else oddly enough, this video shows

'The EPA says the added fuel economy will save the typical Hurricane Twin-Turbo 510 owner about $600 per year, over the HEMI, based on a 15,000-mile yearly average. Now, keep in mind, that checking the option box for the Hurricane Twin-Turbo 510 will set you back an additional $2,000. Both engines require Premium 91 octane fuel, so using today’s numbers the EPA says you will spend $4,350 annually on fuel for the Hurricane. The Hurricane Twin-Turbo 510 delivers 510 horsepower (thus explains the name) and 500 lb.-ft. of torque, a significant upgrade over the 471 horsepower and 455 lb.-ft. of torque rating of the standard 6.4-liter HEMI V8. Despite the added power, the Hurricane’s additional fuel economy won’t really impress the masses .'

https://moparinsiders.com/epa-releases-fuel-economy-ratings-for-hurricane-twin-turbo-grand-wagoneer

EPA rates these engines at 17 combined mileage on 91 octane in the Grand Wagoneer.

15,000 miles @ 17 MPG takes just over 882 gallons of gas.
87 octane gas here is $3.29, so 882 gallons would cost $2,901.78.
91 octane gas here is $3.79, so 882 gallons would cost $3,342.78.
The EPA says that the better economy will save driver's $600 a year, but don't mention that the 91 octane requirement will cost an additional $441 year.

So, these engines make a little better power than the V-8s that they replace, are rated to get a couple of MPG better (although typical end user reports don't often reflect that), require 91 octane, cost $2,000 more, and (particularly the HO) are much more complicated and expensive to work on.

Someone tell me what I am missing here. Where is the benefit to the buyer?

All of this EPA and emissions and fuel economy is all BS in that the manufactures know how the game is played. Manufactures do their reporting by Corporate Averaging and engine families and they can have a gas guzzler and high emissions (to a limit) beyond the regulations by off setting test results with very overly compliant models in the fleet. The whole reason for the hybrids and EV's etc., in the fleet. EPA and the Feds don't mind collecting the "Gas Guzzler Tax" that you see right there on the Monroney label/window sticker. It's not like all of those EPA emissions and fuel economy regulations just came about they have been here for decades and the manufacturers know how to play the game or delete or modify models. IMO there will be another HEMI V8 especially if Ford and GM don't drop their V8 engines. Do you really think an inline 6 or a turbo 4 or anything other than a V8 will be a good option in a RAM or any other towing capable or workhorse pickup truck??

Stellantis would love to keep selling the Hemi V8 whether the current version or a new one BUT BUT BUT as I've written before, automakers are squeezed by the CAFE Standards and are left with no choice. 2025 CAFE is 54.5 mpg! Don't blame the automaker/automakers. I have to leave it at that because this is general forum.

What does CAFE stand for?

Corporate Average Fuel Economy. Their fleet has to average 54.5 or whatever and they get fines if not met, they're getting eaten alive by the fines at the moment. Their head of powertrain said it best, they had to decrease the engine size and increase the power, the TT I6 accomplished that. They dont sell any small cars to make up the difference, all they sell is Jeeps, Rams and muscle

Now all know why you got the title below your user name. Both the 500+hp Hemi and the Hurricane turbo require 91 octane fuel, yet you blather on about 87 octane and wonder what the benefit is.

You don't even know the parameters of the question, much less capable of understanding the answer.

as said, Corporate Average Fuel Economy.
plus, any that don't meet some standards, are rewarded by the new owners paying a "gas guzzler" tax upon purchase.

I am not surprised that you bring up the coward mod that uses his own special powers to troll and snipe in safety.

I made a comparison of the merits made in the article. You choose to ignore those and go off on a tangent about octane or some such nonsense. As usual, you are just being a troll with nothing of merit to contribute. All you can do is bash and complain. You can bring nothing of consequence to the conversation. But that in not your mission. Your mission is to be a TROLL. And you are very good at that.

Say hi to your troll mod butt buddy for me.
