An internet prophet says 2027 for the 5.7
Again, why would they shift gears with the 6.4 going into Wrangler but offer a SMALLER V8 in the TRUCK version?
Jeep has done some stupid things, but that would really be amazing -
Gee, we build Wranglers with our big hemi engine - how about putting the SMALLER V8 with less power into a TRUCK that we brag about being able to tow.

I can’t answer your question, Just what I saw, which may or may not be just internet blather,

6.4 in 2026, and also 5.7 available in 2027.

If it's from the joker who I suspect it's from - LOL - he makes a ton with his crystal ball and should be called "Oft Wrong garage"

Have you read the first couple of pages of this thread?

Maybe because they can rate it to tow more with the 5.7L as you pointed out the 3.6L tows more than the 6.4L.

That's about the only reason I could think of them doing that.
It makes no other sense - detune it a little bit to control the heat at full power and still get close to tow rating - likely would follow the same path as the diesel - slightly lower towing, but many won't care.

**IF** they did offer a 5.7 I could see them beefing stuff up like larger brakes and HD springs to get a slightly higher rating edition. Chevy did this with the heavy half in the 70's(though that was to skirt emissions)

Who knows, maybe with two or three model years remaining for JT now Jeep is going to go big and offer both Hemi engines to go with the P-star. That would be amazing IF and only if they make the 5.7L a relatively small upcharge. Like, let’s say you can option the 5.7L on any trim from Sport S to Rubicon and it’s a $4,995 upcharge (5.7L engine and more robust 8HP75 transmission as a package). In that case they would sell them faster than they can make them, and this would give them something the competitors don’t have which Jeep desperately needs right now in the face of stiff new competition.

But, I still maintain that back in 2020 when I had my Max Tow JT engineers were telling us that the 2.0T wasn’t going to be offered because they couldn’t keep it cool enough during SAE J2807 testing and I don’t see how a V8 is going to help that cause any. So I’ll believe it when I see it. I think they either don’t do a V8 for JT, OR maybe they do it but they drastically reduce towing capacity which is the opposite of what pickup buyers want. Tough either way…

I wonder if the heat generated by a turbo four cylinder is 'different' than that of a 5.7L. Turbo motors are generally bad about generating really high oil temps (the turbo is oil cooled, after all), and the turbski being tight to the engine helps put a lot of heat in one spot.

The V8 has no turbo (may or may not be easier on the oil temps?) and won't have a heat compressor stuck to its side.

Just talking out my ass, like the Motel 6 Hemi is coming soon guy...

I'd look hard at buying one if it didn't cost $70K, and if it was rated at 5,000 pounds or more. That would be close enough to do anything I need to do.

Otherwise my next truck will be a fullsize - though ironically I am considering things like the 2.7 Ecoboost then 😂

other reason to put the 5.7 is price and you still get a V8

How about all the reasons why it isn't necessary 🤔
Thats the perspective of Stellantis

Think back to the diesel - I doubt you'd get HIGHER rating as it's not about the springs and so on - it's about heat control in this platform with this nose
The diesel didn't gain them anything for tow rating because of heat.
I gave an example earlier how GM LOWERED the tow rating of a pickup to make it better on the trails and so on. They lost cooling area, so had to lower the tow rating.
Again - 3500 for the 6.4, while 5,000 for the 3.6 - in the Wrangler
Until they make the Gladiator into something bigger with a bigger nose, I doubt you'll see higher towing capacities any time soon, and especially not for a V8 kicking out more BTUs of heat per mile.
Brakes and springs aren't going to do it - this isn't the 1970s and today they do the SAE testing

It's not surprising the JL 392 has a lower tow rating than the JL 3.6.
Ram did the same thing with the TRX.

You never know what Jeep will do. For the 2026 Wrangler Rubicon there is a Steel Performance Hood Group which is the Mojave type hood and there is no info about that option.

You get it with a Rubicon X no matter what. If we actually accept that Jeep as it comes in, at this point up in the air as Jeep as f'd up the options - I'd prefer to trade for a Rubicon aluminum hood. Why the hell would I want a heavy steel hood? Because it looks cool?

The people on the dark side - I mean, Wrangler side of these forums claim it's a misprint and they really mean steel bumper. Nope, sorry, it's a steel performance hood.. .The bumpers have their own line item in the build sheet. .
