new I6 vs old V6

[Old Dogger]

I never purchase the first year of anything new. There will be some issues with it, as there always are with new product. I am very happy with our 3.6 engines, and am currently dealing on a 392. The Hemi is another long term proven engine.

...everyone says don’t buy first year productions. so keeping all of this in mind, why is it that when an I6 thread comes out, everyone can’t wait for it to make its way into a wrangler?? the only thing i can put together is that the increased HP is worth the risk of having a first year turbo engine? correct???

There's always going to be a constituency of early adopters who want new technology for the sake of having it. IOW, not everyone is dissuaded by first year production. By extension, this means not everyone is actually saying Stay Away.

I'm rarely an early adopter, period, but I did go all in on LED vehicle lighting, and flashlights, and weapon lights, as each came to market. Money well spent, IMO. Granted, even the best in each linked category is an order of magnitude less costly than will be a fancy new engine.

So far as I know, the 2.0T in the Wrangler remains reasonably reliable and functionally unchanged from its original 2018 model year introduction. Five years on, it's clear that it was a reasonably safe bet, but that's just hindsight talking. Perhaps the new I6 TT, if or when it finds its way into the Wrangler, will eventually be able to make the same claim.

The quicker it is released the faster they can start working out the bugs if any should arise. The I6 should have a great power band with smooth power and nice torque down low with the turbo and power throughout its range.
The V6 is great for what it is and I have had many but I’d love a turbo I6 in the Jeep. Ever driven a BMW with their I6? I have owned a few and I love them.

Can anyone point to any information from a reliable source that indicates that the new twin turbo inline 6 is going into the Wrangler?

I don't see it happening. It's rated for too much power and the photos I've seen off it show a lot of plumbing that would be hard to shove into the Wrangler engine bay.

For arguments sake, no one saw the HEMI going into a Wrangler either. Not that I would buy the TTI6, but I'd like to see it happen for the guys that want it.

I believe the initial source of rumors/speculation about the i6 going into the Wrangler goes back to David Zatz, who founded Allpar decades ago and first broke news of this engine 5 years ago. He's made several mentions of such while writing for Stellpower, including the potential fitment challenges for non-STLA platforms (Wrangler) that weren't designed for this engine. All along he's known more about this particular engine than likely anyone outside of Stellantis, and he wrote this..

The new inline six-cylinder engine, possibly the last completely new gasoline engine to be made by Stellantis (Hyundai announced today that it was stopping new gasoline engine development), quietly joined the production list last month. It will have standard and high output versions, and will be used in the Ram 1500, Wrangler, Gladiator, Grand Cherokee, and Wagoneer, joining the Dodge Challenger when, in 2023 or 2024, a new generation hits the streets.

And no idea if the found Excel spreadsheet is from a reputable source, but it does show the Tornado GME T6 aka Hurricane 510 with both JL/JT applications. There's other pages from the spreadsheet at the article, but it just seems like such a mundanely specific thing to create as a 'fake' that very few people would give two shits about.

Searching the Internet for more information on the six-cylinder engine, we’ve come across an Excel published by Centro Ricerche Fiat. As the headline implies, the file in question lists four applications of the GME T6 within Fiat Chrysler: the Ram 1500 (internally referred to as DT), current-gen Jeep Wrangler (JL), Gladiator pickup truck (JT), and the Wagoneer (WS).

I will jump all over a straight six turbo, first off I love forced induction and the 3.0l straight six has been around a long time granted not from mopar but you can bet they’ll take ques from like say bmw. A straight six is basically a perfectly balanced engine easy to work on and the crowd knocking turbos I don’t get there’s nothing mysterious about them and the new turbo tech is spot on. The second they say that hurricane is going in a wrangler I’ll be at the dealer trading in this 23 JLUR lol

Exactly what I was thinking. While this is a “clean-sheet” motor from Stellantis, it’s all been done before. So to go back to the OP’s original question, I think it’s lower risk. Obviously everyone has their own risk/reward threshold.

I’m sure nostalgia is also a factor: the 4.0 straight six was one of Jeep’s most venerable engines.

I feel the same. Over the years I’ve had 2 of these, an old school 258 CI in my CJ and then a 4.0 in my 2003 WJ. Both were solid units and in both years there were V8’s available, but I’ve been a straight 6 guy since I had my Jaguar over in England in the 70’s.

okay, so yes i understand horsepower can be a good thing but i have a thought…

every time i read something about the V6, everyone always says, “there’s 2.2 gazillion made” and that they are tried and true. “a solid workhorse”. etc. i also hear in reference to turbos - “the turbo just adds more crap to go wrong” and “simple is better”. lastly, everyone says don’t buy first year productions. so keeping all of this in mind, why is it that when an I6 thread comes out, everyone can’t wait for it to make its way into a wrangler?? the only thing i can put together is that the increased HP is worth the risk of having a first year turbo engine? correct???

keep in mind, i’m not for or against an I6 engine, i’m just making an observation resulting in a question.

An I6 is arguably the most balanced ICE motor made, far better than a 'V-block' design. And while any 'new' motor can have its troubles, the 3.0TT is being deployed next year in the highest cost SUV Jeep makes. Yes, it could still have its issues (and will) but the fact that Jeep is releasing it in the highest end model it makes, should make people consider the level of testing done. As a large scale failure of that motor in a $100K+ vehicle will not go unnoticed. Frankly, I'm quite happy Jeep has the faith in the motor to release it in the GW. By the time it finds itself in a new Wrangler model (say 2028) the engine will have been thoroughly vetted. IMHO.

Despite knowing about the ‘’never buy the first year of anything’’ belief, I couldn’t help but trade my 10A Rubicon back in early 2018 when I found out that the Selec-track transfer case was available on the ‘’new’’ wrangler….. I must say that I’ve had a lot less trouble with my 2018 than a lot of 2021-2022 owners. I’ve had one S/S and main battery change and all other problems were about the 8.4 inch screen that would bug on me , was flashed a few times and changed once and backglass defrost connection that came undone 5 times, which are all still current problems. Never saw any electronic problem with a party of warning lights like what seems to be very common on newer years. So that belief doesn’t always apply.

Engine wise, my 3.6 has been super reliable and combined with 4.56 gears, turns my 35s with extreme ease, as if they were 31s. So I don’t see myself rushing to trade my Jeep for an engine choice. But then again some people trade for colors, so same logic doesn’t apply to all.

With this said, I am pretty confident that the new L6 will be a lot less problematic than the L4 was when it was introduced, since the Jeep techs at least now have a clue on how to fix them, which was the biggest problem of the L4.

And never forget the amazing 2JZ GTE Supra engine. Probably the best turbo 3.0L inline 6 the world has ever seen. Loved mine, bolt on parts made it an absolute monster.

I love my old 4.0 in my TJ-one of my favorite vehicles Ever. Went literally everywhere in that thing. Trouble free and reliable as a stone ax. Only had what 190 hp, but plenty of torque. Absolutely great engine. I’d think a non turbo straight six as a standard with a turbo as the hot engine. I’d suspect that Wrangler will be”down the line “ a bit and not introduced during the first year of production, so hopefully it wii be proven prior to the Jeep ever seeing one.

I'm gonna burst a lot of hope bubbles here but just in case non one thought about it, if they didn't put the Diesel into the 2 door because it was too long then to all the 2 door owners, don't get your hopes up, I would be Extremely surprised that they would offer it in a two door even if they start offering it in a wrangler, I can possibly see it in a 4 door for some models (probably a premium etc and I could see it being the motor replacing the 392) but I don't think its happening in a 2 door ever unfortunately for a lot of hoping owners.

The 4.0 straight six was one of the most overrated pieces of shit engines ever.
Heavy, gutless, fuel sucking and most years in the TJ’s had problems.
That being said, I’ve had a handful of them over the years and never had any problems with any of them but also never owned one with more than 110k miles on it.

This is a complete guess on my part but I'm betting that has much more to do with the heavier weight of the diesel engine ... more vehicle behind it helps offset the heavier weight up front. It could also be to keep their total configurations to a manageable number.

What is the weight difference between this new engine and the current EcoDiesel?
