You can still get the 3.6 with an automatic transmission in Rubicon trim. You can even order it with 4.88 gears.

Just picked up a 2021 JL with the 2.0. I was searching for a 3.6 as I was skeptical of the 2.0. My wife really liked a Snazzberry Altitude with everything she wanted. After driving the 2.0 I am pleasantly surprised. This thing rips.

3.6 is nearing the end of possibilities of advancement. It's about as far as you can go.
And it's necessary to sell world-wide, size matters. If Jeep can't sell in the EU, they crash and burn.
Selfish Americans think only of selling to the customers here. If Jeep can't compete there or sell there, Ford or someone else will jump in and fill the gap - Jeep loses.

I believe they are also taxed on engines over certain sizes?

I saw that just not into spending that kind of extra coin on rubi in a wrangler. The willys pack comes with the wide axles, larger factory tires, 4.10s, top stereo, led pack and a bunch of other stuff for $7,500 extra which seems decent enough.

Other than the very early JL's with 2.0 engines that caught fire and got sorted pretty quick, I think it is a decent engine and would have no problem getting a vehicle with it.

We have a 2019 JL with 2.0 and it has been a great engine especially in the little 2 door

Never owned a 3.6 with follower or cam issues (no tappets) and we've had a number of them in my JTs and my wife's Grand Cherokees. I'd not be a bit afraid of a 3.6 in anything.
That being said - the only choice for JL now is the 2.0



the 2.0 does really prefer higher octane fuel, especially in hot weather or with a load.
It's DI so will require a closer watch on oil changes. Direct injection is more prone to fuel contamination of the oil - but that's true of any DI engine.
(thankfully the 3.6 is not DI)

We have a 2.0 in our 4xe and that combo blows the 3.6 away in power and torque.
We drove almost non-stop (except for multiple fuel stops due to the tiny tank and poor mpg) so we were running as a hybrid with battery down and it was fine.
Granted, we had the added torque of the electric system, but it was running the 2.0 the whole trip once we got into GA from FL. It never shut off unless we were in heavy heavy traffic or stop and go city driving. It did fine.
Can't say how it would be in a non-4xe, but as a combination it is excellent.
I'll never feel the same about the get up and go of my 3.6 in my JT after driving my wife's JLU 4xe with 2.0
I believe you are spot on. We had a 2.0 JLU and there is a big difference from the 3.6. We enjoy and have the 4Xe Grand Cherokee and a 3.6 Mojave. The 2.0 just seems faster overall than the 3.6. But the 4Xe is in a class all by itself. Think V8 without the sound (that part sucks) but all the smiles of speed and torque. There is a reason for this too The new JLU is pretty badass. Either way you won’t be disappointed.

I read somewhere that one of the new EVs has a feature - speakers - that allow you to have V8 engine sounds as you drive. Man, I'd be recording my 73 and blasting that around town and setting off car alarms.

I have a 2.0 in a 2019 Wrangler 2dr and the 3.6 in my 2022 Gladiator. Yes, difference in weight between the vehicles, but the 2.0 is much spunkier and gets better MPGs. I favor the 2.0 without a doubt

The only issue i foresee is direct injection and the need for a walnut blast ~100,000 miles. Beyond that, turbo 4 bangers have become the norm and really can last quite a while.

I wonder if pouring a Coke bottle full of water slowly through the intake would clear off the intake valves.....................

They make chemicals just for this purpose, and they are said (I cannot vouch for this) to work really well on NA DI motors. The argument is what are you throwing at the turbo hot side when the carbon breaks free.

Arguments included: heck no you'll destroy your turbo, and:
the carbon is soft and small when this chemical goes to work on it.

I never tried it on my old Ecoboost 2.0t for fear of destroying the turbo hot side, as I already had 70k on that motor before I heard about this process. Maybe if you started early and kept up with it from a young age?

Not a fan of throwing a ton of water in a motor...

Or you could ascribe to the snake oil of sea foam into the vacuum line ?

We've done it dozens of times - decades ago. My first shop boss showed me that trick. Got rid of knocks and other issues. Sometimes the carbon built up compression to the point of ping, other ties the carbon built up and held valves off their seats, and still other times, carbon built up on the piston heads and it smacked the head on each up-stroke. I've torn down a few with that sort of carbon and it gets pounded until it's hard as a rock and near impossible to chip off.

Or use top tier gas with each fill and not run short drives all the time.....and accept it's more like 40 years ago as far as watching build-up on the valves and so on. Buy a borescope and check at 90K
