2.0 or 3.6 ??????

[Windshieldfarmer]

I have the 2.0; power is never an issue…especially at altitude where the turbo makes a huge difference over the NA V6. That said, the 2.0 sounds like a tractor when cold…something I do not like. So far the 2.0 is proving to be pretty reliable. A 392 would be fun but that thing is way overpriced…. If I were spend that much $$$ and not planning to do hard core rock crawling I would look at a big battery Rivian…far faster and fairly capable at the same time.

I’m trying to decide which engine to choose when ordering a 24 Ribicon X. I do very little off-roading and love going fast. I’m hooked on jeeps so buying a “muscle car” isn’t what I want. I have a 22 4Xe but the benefit of 22 miles on the battery doesn’t fit our long distance driving habits and the scarcity of charging stations when traveling usually leaves us using the ICE most of the time anyway. Crappy mileage on the 392 and big price tag is a turnoff for that model. Any suggestions?

Our 2.0 is silly fast. It’s a two door and feels like a go cart?

I have a 3.6 unlimited rubi manual and a 2L turbo 2 Dr auto. Very different between the 2. Love my manual and the torque, but the 2 door is zippy as hell and gets better gas mileage

I’d go 3.6, unless you really don’t care about engine sound. The 3.6 is extremely reliable, the 2.0 is proving to be much more reliable than people first thought they would be and it is slightly better mpg wise.

At the end of the day, any engine is good when the axle gearing is dialed-in with the tire size.

Go try a 392 for yourself, and if it moves you, go buy one. You never know what may be available in the future....could very well be that the 2.0 might be the only ICE engine, or there will only by hybrids.

Good luck finding a 392 to do a test drive in. I dealt with a good size dealer that moves a lot of inventory. The 392’s come and go on their lot. It was mentioned that there were no test drives not that I was considering one anyway. My 3.6 with the XR package and the 4.56 gears is a rocket for a Jeep. Definitely meets my needs both on and off road.

I opted for the JLUR 6-speed 3.6l without e/torque. I chose it for the simplicity of a naturally aspirated engine with complications of a turbo and a secondary battery (that seems to cause a lot of issues). If acceleration is your thing, the Rubicon probably gets off the line faster with its 4.10 gears. The other models with a higher final drive ratio (and road oriented tires) will cruise faster at a lower RPM which definitely makes a difference in your MPG.

The e torque has actually caused less issues afaik than the non etorque you did get with its auxiliary battery, but the aux battery delete is a simple matter while etorque is integral to the design.

Neither of those motors are fast and at the end of the day none are breaking 100mph. That said fast is a relative term. Either 2.0 or 3.6 is fine and you already said you weren't doing the 392 which would have been the only motor remotely 'fast' in a Wrangler as it goes to 60mph in 4 seconds where the other two engines are probably looking at a 6 as the first digit unless they are two door, bare bones on factory passenger style tires.

I’m disappointed this hasn’t been shared yet.

I've owned both. A 2019 3.6L JLUR (sold) and a 2023 2.0L JLUR. I prefer my 2.0L. I run 87 octane in both.

You want a 392.

If you’re buying something because you’re Ricky Bobby and wana go fast, neither the 3.6 or 2.0 go fast. They’re Jeep wranglers. Maybe look at a Grand Cherokee SRT.

I’m confused by this post in general. If you don’t really off-road, don’t get a rubicon. You’re just wasting $20k for no reason. If you like going fast, the wrangler is a bad option unless you get the 392. However, you’re concerned about gas mileage, so the 392 is not an option. Sounds like you need a fast car with reasonable gas mileage…

I went back-and-forth over this before pulling the trigger myself....
I ended up with the 2.0....reasons?
1) Fast, which was a big change for me and my Jeeps (I had 2 - 3.6s and 2 - 4.0s previously)
2) MPG - it is a noticeable and HUGE difference
3) Just wanted a change

The thing about needing a higher octane gas is a myth IMO. I've had nothing but 87 octane in mine for months now. Just put in some 89 octane yesterday just for a trial. No noticeable difference to me.

Bottom line for me in ordering 3.6 in 24 2 door...it can be had with a manual. End of discussion for this child.

I've owned a 2015 JKUR 3.6, and currently own a 2020 JLUR, 2.0T. For me, the 3.6L gives me peace of mind because it is naturally aspirated and uses regular fuel. I would opt for the 3.6L if you plan on keeping the Rubi for a long time. On the other hand, my 2.0T has more pep and has better gas mileage (even when using regular). The downside of this is that the 2.0T uses premium fuel but I question its longevity before something goes wrong with the turbo. I am not a fan of turbos because of its questionable lifespan over time. Also, Jeep recommends using premium fuel but you can use regular. I use regular fuel all the time and have not had any problems with this engine, so far. BUT, using regular fuel in the long term could cause a problem with the turbo (my hunch). Therefore, for the sake of longevity - pick the 3.6L. For fun with slightly higher operating cost due to premium fuel - opt for the 2.0T.
