Stellantis Brings The HEMI Back !!

IF

Do you mean like the grid heater bolt/nut falling into a cylinder?

Nah, more like cheap connecting rods turning back into the dust they were made from.

Powder metallurgy for connecting rods? I didn't see that one coming.

I’ll pass on a straight six with no dipstick !

Already been in use on the hemi.

Nothing new there. I worked in a powdered metal factory for over 25 years. Although our plant did not produce connecting rods, other places did, mainly for GM.

Pretty sure most of the Ford modular motors have been using them all along.

Cummins motors live forever under just those circumstances....and inline motors are by nature, torque monsters. Just look at the old 4.0 Jeep motor. If it was designed properly for the intended use, it should do just fine. Just like the Cummins, and the 4.0.

The hurricane is 3.0 liters making about 2.3-2.8 hp/cubic inch depending on if it’s the 420 or 520 hp version. That is a lot of stress on a small light duty engine with sequential turbos in a heavy vehicle. The Cummins trucks in stock form are either slightly under or slightly over 1hp per cubic inch and have massive internal parts compared to any light automotive gas engine. The jeep 4.0 is laughable. The reason for their longevity in stock form is their low output, only about .75 hp per cube, and their fairly robust design. They also are not torque monsters, they are ok, and nearly adequate for the vehicles they were installed in. I like my 4 liter TJ, but I think a 2 barrel 318 would make it more fun to drive.

I think the hurricane would probably be good in a car, but who knows about long term reliability. Seems like all of the newer direct injection gas engines , and turbo engines have a lot of issues that get expensive to repair. I’d rather have a larger n/an engine myself.

Have you seen the internals on a Hurricane? I haven't yet, but I do know my ecodiesel is overbuilt, with six-bolt main girdle setup, beefy rotating assembly, and bone stock output (for 3.0 liters) of 240hp and 420 lb-ft. Banks makes their own version called the 630T, using stock architecture with updated boost and fuel, and it puts out 301/505 - same as a 6.6 duramax at less than half the displacement.

It's a shame to see folks rule out a new engine design, just because it's new, and/or smaller displacement.

Especially before they have a chance to get on the road, and put up some data.

I equate turbo's on engines to steroids in humans: they are going to be life shortening, with nasty side effects.

I suspect the Hurricane has pretty beefy internals. The HO one is rated for 28 psi boost out of its turbos. If they aren’t beefy, they are an explosion waiting for a place to happen.

My son has a 1992 Twin Turbo Stealth. When we tore it down to replace bearings, I was surprised to find a one piece stud girdle holding the bottom end together.

Just kiss the RAM 1500 goodbye and look at the 2500 or 3500 models. Ouch on the sticker price though.

the Ram 1500 isn't gone
it's just 'The Classic' version 1500 Ram,
they still make a new Ram 1500, New 1500 Ram's in other/more costly trim levels
that "classic" was the cheapest model they made, probably best seller (maybe ?)
& the dumbasses bean counters, talking heads at Stellantis, closed that plant down
& laid off most all of the (2,400 ? UAW) workers too
a while back now

Agree, but the new Ram 1500 isn't available with the HEMI. So, it's gone (not an option) for those that want a HEMI in a 1500.

Gotta go with a Ram 2500 or 3500 if you want a HEMI; like I said earlier.

But hey, I see a lot of people cruising to work/home or to the store and not ever carrying or trailering anything large or heavy in their "grocery getter" RAM 1500 pickups. The Hurricane engine is probably fine for their use.

I dunno...maybe some people get a pickup because they can't find a suitable (large) 4 door sedan?

I'll bet the new Stellantis Management (now purged of the EV Lover)
will continue the use of the Hemi, in the future too...

It'd be a smart move
That's their demographics/buyers for the most part

not the straight 6, with a couple of snails attached
no matter how much they market them
I'm sure it a fine engine, just not for the masses "yet"
maybe after it's been proven for some time, barely even out of diapers

I equate turbo's on engines to steroids in humans: they are going to be life shortening, with nasty side effects.

And yet diesels without turbos are practically useless for any real power. They seem to go on forever and ever with turbos though. Something like a Supra with turbocharged inline six has proven that they can last a long time too, even when built to four digit power levels.

One thing about the Hurricane Six is that it was designed and engineered from the outset to handle the power; unlike the wimpy slant six bottom end, this one has seven main bearings and a very beefy rotating assembly. Taking two similar power levels, a highly boosted low rpm engine will have much less rod stress than a high rpm. non boosted engine.

The hemi wasn't originally designed to handle Hellcat power either, which is why the block had to be redesigned to avoid blowing up, but the Hurricane was built to take it from the outset.

Agrre with everything you said, but they are not sequential if you are meaning compund, they are twins, each boosting 3 cyl. In a car It'd be bmw cool, but not dodge cool, imho, so I agree, bug V8 for me.
