HEMI® Power To Keep Going In Ram Heavy Duty Trucks

Not at all…. The Hemi is an excellent engine if you need more you need a diesel.
There is another aspect to this. Some consumers (commercial or private) are also concerned about the War on Diesel, such as in states like CA.

If you are buying a truck that you want to get 10 years out of..... putting your faith in the CA Legislatures and the "Climate Change" mantra if iffy at best.

They might not outlaw diesel, but they have already shown, over the last 20 years, that they will dramatically change the rules on diesel.

Safer to go with the Hemi.

Definitely an aspect for commercial buyers, especially ones with non-pickup beds. You should see the insanity in CA- mostly it’s not laws passed but administrative codes produced by the AQMD. They operate under the clean air act and make their own rules. Consumers can get around things but businesses even can’t run off road concrete pumps or skid steers unless tier 4 compliant or face tickets- all those have to be registered with CARB. Small contractors can get around things but it’s frankly BS.
 
A lot of commercial and gov fleets are moving to gasoline trucks for cost and maintenance savings the last few years as well. Gasoline engines are much more tolerant of idling than diesels are as well (though the Hemis are known to have some Ricki no issues with excessive idling).

They already said diesel and gas vehicles wont be sold after 2035 so who knows all i know is im not in the US and i wont be buying gas vehicles
 
Just Google around, everyone has hell. Supposedly there was a thicker manifold 2019 on that splits open instead of destroying the heads. But the original design flaw is the back cylinders do not have enough cooling. Same thing that is now taking out the prior generation Tundra V8, all be it much sooner and more catastrophic with head gaskets and warped blocks. My exhaust manifold bolts have been re-done 3 times, the back ones held from the last time but it loosened up the front ones and with helical coils in the back we are scared to do it again. Basically the heads are trashed. Lifters have always been a Hemi battle. I have one failing, probably started failing at say 180K. But at this point not replacing the top end of a 200K mile engine, completely new heads. The good news is the ZF replaced the old clunker transmission in the Power Wagon, that was a 60K transmission in reality. But these exhaust manifold and lifter issues are terrible.

Would you be so kind to link to a single instance of a 6.4L Hemi exhaust manifold bolt issue? People like to say it’s an issue but nobody has seen one that I can find. I have asked about it before on here and nobody can find any evidence of it. If it was a widespread issue it would be easy to find information about it.

No new gas engine. No new cab. No 3500 rebel or power wagon. No multi function tailgate. No 4500 pickup option. The updated interiors along with new mirrors and soon to be new 8 speed are all welcome changes. But those along with the other things I mentioned should have been all been released by now in my opinion.
Thank our govt for the slowdown
 
Is it true you can’t get a mega cab in hemi form? All I could configure on the website was a cummins mega cab.

I am also interested in a gasoline version megacab.

Here is a thread with some more information on ordering and configuration.

I don't know anything other than what is being posted on the internet, this forum, youtube and the cummins web site.

My own personal "speculation" is that the 2025 HDs are going to:
- Start off with the one engine option - the Cummins 6.7 diesel
- During 2025, they will release the gasoline version of that same engine and use it instead of the hemi engine

This would make it much easier both in the factory and in the fleet repair shops to support.

Again - I am just guessing.

But if I were a fleet high volume buyer, with an in house repair group, it would be attractive to be able to buy a truck with as much in common as possible for gasoline and diesel versions.

January and February are the release dates for both engines
 
I can't imagine they'd offer two radically different gas engines. A heavy duty gas turbo inline 6 would sure blow Ford and GM out of the gas market though.

Probably you are right. My logic is that fleets that normally would use the 6.7 diesel would want an engine that is similar but in gasoline for states that are overly restrictive like here in CA.

It might be my imagination, but at least historically, an in line 6 looks a lot easier to work on than a V8 space wise. Most of my experience is with gas vehicles though.

Looking at their brochure it looks like they're targeting light commercial and RV.

While I have utterly no idea on this I'd have to guess the in house Hemi is a fraction of the cost that they'd have to pay for this engine. Do you think people would pay maybe a 3 or 4 thousand upcharge for this over a Hemi?

It would seem it would be a very easy engine to use since it's pretty much the same as the diesel as far as it's configuration. Probably could use the same transmission with a different tune that the new diesel is going to use. Cooling system probably the same. Surely there'd be a bit of economy of scale with that.

Looking at the HP/torque graphs I'd be interested. Sick of emissions nonsense with the diesel and it appears it has enough torque at the right RPM to serve many people's needs. It's the same torque as the manual transmission Cummins were just a few years ago. Few complained about those.

Of course Stellantis are experts at shooting themselves in the foot so............

Zero chance the hurricane is easier to work on than the Hemi

Well - if I were buying a 3500 megacab, limited edition, that is already almost 100K. So does 4 or 5k more matter ?

Repair bills and extra license fees in CA can easily hit $1K / year,

If it is easy to work on, I might do some things myself vs if they are hard to reach. I enjoy working on stuff, but my back doesn't.
