3.0L “Tornado” Straight-Six Engine (GME T6) Coming to Various Jeep Models?

[2018JLRUSellersremorse]

Not available in the 2 door, but the diesel has that power. Well, not the HP, but more than that for TQ. And, frankly, you don't need HP unless you are going to high speed. TQ is what gets you moving. HP keeps you moving faster.

And the 4Xe already has it. 375 HP and 470 TQ

Not really, it says that the other engines are destined for.
5.7 Chrysler 300, Dodge Charger....
6.2 Supercharged Hellcat for Challenger....
6.4 Apache for Jeep Grand Cherokee SRT....
6.4 BGE for Ram 2500....

But it's blank after the GME T6 3.0 so we can't be certain what vehicle they are building the engine for yet.

Looks like Stellantis edited the website. I did some heavy searching on the Stellantis media site yesterday (the info was hard to find) and it definitely listed this engine on there being produced in the Saltillo engine plant in Mexico As well as the models it was going into. I’m guessing they didn’t want all this info to get out yet. Link to the plant sites fact sheet. I had found the info here, gone now It appears. https://media.stellantisnorthamerica.com/newsrelease.do?id=333&mid=105

Here’s a link to all the manufacturing sites info. https://media.stellantisnorthamerica.com/factsheets.do?&mid=105

Well stated and sadly true...

While I agree that the ICE's days are numbered, I don't think it's going to happen before I'm eating baby food...again. I think you have at least a decade and more likely a few decades before the ICE is no longer available. The infrastructure for plug-ins isn't there for the masses. The "grid" has been aging and being overworked for decades. Put even another 10% of households on with plug-in cars and it can't support it. There's lot of things that have to happen before everyone will be driving electrics.

That'd take a 300,000 mile engine and make it like 100,000. A turbo itself is lucky to go 100k, less if it's doing heavy boosting a lot. Bearings go, then the carbon/ceramic oil seals, engine starts eating aluminum and oil from the compressor side..... Good for the 30-50k owners, bad for the 10-15 year owner crowd.

You're acting like forced induction production cars haven't been a thing for the last 30 years. The vast majority of consumers will be spending nearly all their time in low-RPM highway driving barely touching boost, not racing the damn things. The Subura Legacy has had turbo options since the late 80s and has been long known for engines that last hundreds of thousands of miles with proper maintenance.

I'll agree that forced induction puts more strain and wear on an engine vs naturally aspirated, and I'd personally love to see more NA 8cyl engines put into production, but as the options start dwindling down to either you get an electric or a more fuel-efficient smaller engine, I'll gladly take boosted ICE over no ICE at all and be thankful to finally get an engine more powerful than the relatively under-powered Pentastar.

I totally agree, just try and convince the tree huggers of that...

Anyway I recently ordered what may be one of the last gas powered super trucks and selling my 19' Longhorn...A big, bad 22' TRX should arrive sometime in January!

Remember they developed the Pentastar with a lot more in mind. They worked on versions of it that would be turbocharged, direct injection, different displacement, etc. The engine in the Maserati SUV is based on the Pentastar. So forced induction was definitely a possibility. I don't know why they shifted gears towards this new design over the Pentastar. But it is probably a financial decision.

 

[roaniecowpony]

The new inline 6 would be built to handle the turbo. The 3.6 is not designed for it.

Yeah, an open deck wouldn't be my first choice for a supercharged engine.

Still, turbochargers on performance engines, especially small diameter, high spool rpm, turbos, aren't going 300,000 before the turbo needs replacement.

$1,000 to a replace a turbo at 300k miles isn't exactly a deal-breaker compared to everything else that would've needed replaced/repaired by that point <shrug emoji>

You are assuming that the goal is to continue to allow all people the freedom to own and drive a vehicle. If bureaucrats simply legislate ICE vehicles out of existence, they needn’t worry about the lack of infrastructure to support mass EV ownership. Public transportation, long vaunted as the “true green alternative” (alongside pedal power), would then become the default… as it is in most second and third world nations. Only the wealthy Elite will be able to afford to own an EV and use it. Welcome to 21st century America, peasant…. Where the true meaning of “equality” is the lowest common denominator: Equality of Poverty.

Funny how much of the rest of the First World nations have heavily invested, and use, public transit systems for moving people around. It’s only North America that seems beholden to the automobile.

You’re being overly dramatic. If we want to keep personal transportation a thing, we must eliminate or greatly reduce our reliance on ICE.

Just curious, but why did Stellantis move engine production from the US to Mexico recently? Afaik, the Pentastar was still being built in the US up until 2018 models, iirc.

Two different engines.

Up until 2018 the JK used Gen 1 Pentastar which is built in the US.

JL uses the Gen 2 built in Mexico

All FCA needed to do was twin turbo the 3.6L...

They were, along with direct injection.

But an article from Nov 2019 said that poor results in early tests on direct injection are what prompted development of the new I6.

Allegedly due to poor early tests with direct injection.

Well DI is still not perfected though it has improved amongst some of the OEMs. Funny, there are plenty of turbo MPI engines out there that are pretty effective and efficient, but I digress...

Good info, thanks! But, I was more interested in the 'why', as in why did they need to move production to Mexico, regardless? Compass, Cherokee, Renegade, sure, if it somehow keeps their costs down, why not? Imo, a $50k+ Rubicon or Grand Cherokee 'made in Ohio' should be using a US-built engine.

According to Stellantis' website (link posted above by @legacy_etu), they're supposedly still building 3.6L Pentastar 'for Wrangler' engines at plants in the US, but I haven't come across a single window sticker in the past few years to support this.
