Silly argument from the beginning here -- who cares ?
the 2.0 and 3.6 fill almost the same hole so if they kill one it doesn't matter
As far as the manual goes, Jeep will have that available for the next 40 years, who cares what engine they bolt it to and why would anyone think it couldn't just as easily mate to the 2.0 flawlessly or the diesel, just because they dropped it from Sahara meant nothing as Sahara is more of a luxury middle between the basic Sport and the Rubicon made more for folks who actually like the mall crawler term, if you really wanted an off road Jeep and could afford a Sahara you would have added a little more and gotten the Rubi
The manual is perfect for the lowest end cheap Jeep and the "built for off road right at the factory" Jeep and the sales probably showed just that
Besides that the Sahara has those extra vanity mirrors and makeup cases at no extra charge for the ladies
Just messin around guys - I love em all ?

That’s fair.

Unfortunately, whatever we wish has little bearing on things.

Two facts to keep in mind:
  1. Stellantis continues to produce and sell vehicles that were originally developed ten years before the I-6 was launched. The chances that the two will work with each other are pretty slim
  2. The recent announcement that Stellantis plans to continue production of the 3.6 V6 signals that it cannot accommodate the I-6 on every vehicle. If it did, it would simply get rid of the V6
I have no idea if JL is one the vehicles that won’t take the I-6. But the fact that JL started development well before I-6 did, and how tight everything looks under JL’s hood, strongly suggest to me that it is unlikely to fit. As I recall, FCA struggled to fit the 8-speed on JL. It had to extend the wheelbase by 1.5 inches, thoroughly redesign the firewall and the floorpan, and delay launch by six months.

Hopefully, the I-6 was included of JL’s mid-cycle redesign plan...
I was there when the first SRT Viper V10 made it into a TJ. I am sure an I6 can fit in the JL.

I would think that the 3.6 would be their biggest seller by far. Taking into consideration that it is used, in most of the Jeep and Chrysler vehicles sold. So why would it go away….

I don’t think they will drop the 3.6 anytime soon until the epa squeezes tighter and forces them to drop it. The 3.6 pentastar has been one of their most popular and successful engines ever. Not a very exciting engine but a great all around build and reliable.

There is no 12v starter on a jeep with eTorque? Everything I've read says different.

Curious, where does one connect to try to jump the 48v battery?
Yes, there absolutely IS a 12V starter on the JL with e-torque.

The 12V starter is used to initially start the engine. The E-torque is a belt drive system which is used only during the start/stop cycle at traffic lights, etc., not for the initial start.

The E-torque belt drive starter is EXTREMELY smooth, almost instant, and far superior to a normal start/stop system that uses the 12V starter. Of course after the warranty runs out, who knows how reliable it will be, and/or how expensive it will be to repair. The E-torque system adds a LOT of extra complexity that the non-E-torque system does not have.

So far, after 31,000 miles on my 2021 JL Rubicon, it has been buttery smooth, and extremely reliable.

The reason the 2.0 or another engine has not knocked out the 3.6 is due to simple economics. The 3.6, not being direct injected or turbocharged, is less expensive to build or repair. It also has one of, if not THE, lowest warranty claim costs of any mass produced engine. In that regard, it is the envy of the auto industry. That's why they continue to invest in it and it isn't going away soon.

Ask Ford about warranty costs on their DI/turbo engines. (Not saying they aren't reliable. They are. But they are EXPENSIVE to repair and replace.) In a recent year their warranty costs for engines were $1 billion greater than that of rival General Motors. It became a top corporate priority to reduce it.

A local oil change shop had to replace the Ecoboost in my Ford Transit about 4 years ago after screwing up the filter installation causing its destruction. It cost them $11,000 for a Ford certified remanufactured unit. OUCH!!!
My feeling is the Pentastar engine will "upgraded" to a DI engine in the 2024 model year. When the engine was originally designed it was stated it could be made with DI at some point. I hope I'm wrong. IMO DI will be a step in the wrong direction for the 3.6L. I hope they leave well enough alone and it remains a port injected engine. Flame suit on.

Agree 100%. Most direct injection (DI) engines are very susceptible to carbon build up around the valves, unless it is a DI and port fuel injection (very complicated, and more maintenance/expense down the road)

It could but won't. That ship sailed. Why? There is baggage that comes with it, starting with increased warranty costs. Remember, low warranty claim costs makes the Pentastar very healthy for the bottom line. It also makes for happy customers.

My understanding is that there are no plans for major changes. Just the PUG with running minor changes until it is discontinued. It's all about the bottom line. They'll have optional engines for those wanting more power and willing to pay for it. I'm betting the Hurricane makes its way into the Wrangler at some point soon.

I also believe that while the original 3.6 was made with DI in mind as a future upgrade, by the time they did the PUG they had been pretty solid in their decision to avoid it.

But you never know. I certainly didn't see this investment in the PUG's future coming. I really thought it would be grandfathered and ultimately replaced by the 2.0. But again, the low warranty cost and its positive effect on the company's bottom line just could not be given up so easily.

Interesting, and I hope you're right. The way I interpreted it, they're going to upgrade the PUG. Maybe it's some slight enhancements, maybe it's going with DI. You could be right though, the way I see it is the engine has been around a while, and has been very successful. Why risk messing things up with first year DI in that engine, and the possibility of nightmares in warranty claims. They might be able to get a few more years out of it with a few enhancements and leaving it as port injected. Then again DI is the norm.

I was going to to buy a new 2023 jeep williys with the 3.6 automatic
But when I found out I could only order it with the e-torque I SAID NO WAY
I did a little research on the e-torque and they are having problems
The battery cost today is about $1500 to $3000 depending on the what you may want
It looks like it may be covered for 80K or 8 years put I know it wound last that long so it will have to be replaced under warranty
So in 8 years and the way battery prices are going $2000 to $3000 for a battery or more
My other truck is a 2000 Toyota Tundra with almost 400k on it
So lets say you put 400k on your e-torque and you get realistically 5 years from each battery
At about $2500 each time is $10,000 for battery's and that's if nothing else goes wrong like the dive motor
This takes me back 30 years when I worked at Goodyear and the new corvette came out with a tire size that only fit the corvette
It was about $3000 for a set of tires
I had people literally crying in my show room because now they have a car they cant afford to fix
So I went and purchased 2018 Rubicon from a little old lady
It even has a new starting battery and auxiliary battery So I am good to go
THAT'S MY TAKE ON THE E-TORQUE

high compression engines fail, the little one is absurd, the new 3.6 in JL is too much.. pings all summer on CA hippie gas
try running 91 octane fuel. Ive been running 91 for two years in my 3.6 all pre det. is gone. plus the added 1-2 mpg gain

Could certainly be some things, including DI. I was told by an insider, though, that they've felt the cost/benefit analysis went against DI.

I've not seen any pattern of problems with the E-torque or its battery. That said, I think you made a move that makes good sense if you are nervous about it.

All battery's will fail
The question is are you ready to spend 3k for a battery after 80k miles
The last thing I need out in the middle of no were is for a 48 volt battery to fail
I can swoop out or jump 12 volt on the trail
Good luck with a 48 volt
The jeep Rubicon is a full off road vehicle maid to be used and abused
Leave the E-torque for the Sahara mall crawlers

I hope you're right! I'd rather not have DI for as long as I can possibly avoid it.
