What engine Would You Chose? (Poll)

[y2kcbr600]

The 5.7 should have been in the JL and especially the JT from inception, the 6.4 is just overkill and way overpriced.

Jeep is missed an opportunity to expand the 2.0T e-tourque into a 2.0T non-plug-in hybrid. I would never buy a gas-plug-in vehicle! Talk about an identity crisis.

I love Cummins, but with emissions requirements deisel doesn't make sense in a Wrangler to me.

My choice would be a four speed dual quad posi-traction 409.

With the four-thirteen's really digging in?

As long as we are dreaming, the ultimate would be an all-electric wrangler with one of those new toyota solid-state lithium battery systems that they claim will be scaled up in 3-5 years. They are promising 700-900 mile range with a 10-minute charge time. When that happens, adios to the ICE.

Gotta disagree when it comes to diesels. I’m old enough to remember the smokin, chokin, stinkin, gutless NA diesels. The NA 6.9 IH in Ford PU’s made Gale Banks a lot of money, including from my father, father in law, and just about everyone else be it Banks, ATS etc. …. If you ever got stranded, trucks right lane only behind a struggling NA truck you would want all non turbocharged diesels scrapped. ?

I agree for the big trucks and towing big loads, but a turbo isn’t needed in a Jeep. Different application.

With compression ignition diesels the turbo supplies the high compression for an efficient burn. With the smaller NA IH in Fords or the converted Olds V8 in GM , even the HD 2 stroke supercharged GM Detroit Diesels before adding a turbo they burned your lungs and eyes with the black smoke rollin’ up around the tail lights, thank god and greyhound she’s gone. Oops-thank god and advances .

I remember those oil burners. They reminded me of “Pig Pen” from the Peanuts. Are all the newer small Cummins I4’s turbocharged? I would have thought the modern diesels wouldn’t have the black smoke issue, but I must admit I don’t have a lot of experience with them.

Diesels without boost are inefficient. The added turbo turned the 6.9 Fords into a good PU. I sold the FIL’s Banks turbocharged one to a work friend who still pulls his 24’ RV trailer with it. ? ( those Fords likely made Banks what it is, damn near everyone added one) I would bet my retirement fund the Cummins is and would be profoundly surprised if any modern diesel isn’t.

Makes sense at high elevation?

None of the new diesels, if left stock, put out black smoke. That black smoke is just unburned fuel. And yes, all the new Cummins aftermarket diesels are turbocharged, even in tractors. https://www.cummins.com/engines/repower

I remember the older diesels, without turbos. They were inefficient, underpowered, and belched smoke. The first ones that Ford installed a turbo on it was like a switch had been thrown. Now it worked well.
As for the longevity of turbos, they should last several hundred thousands of miles, with frequent oil changes.

And you need at least 2 of them for when one is in the shop...

What the endless 2.0 and 3.6 engine problems? 3.0 ED 2 years ZERO TIME IN SHOP. Besides them changing my oil for free. 3.6's and 2.0s. The two engines have far more problems than 3.0 Eco.

3.0 is the best engine ever put in the Jeep Wrangler. Clowns. Fuck your V8 we did it half of the cost with better power than the 392.

As a 4xe owner, I will freely admit I would 100% buy an EcoDiesel for my use case if I were to do it again (a 3rd time). No ONE powertrain is a perfect fit for everyone. The 3.6 is virtually unkillable (unless you're the guy that's had 2 die in a very short period of time on this board ) and the 2.0L Turbo has more than earned it's place as a great everyday power plant. The 392 might be overkill for some and perfect for others while the 4xe gets you close to the same kind of numbers with the added short trip fuel saving benefits (mind you with a sketchy reliability history if you believe everything you read). Then there's the EcoDiesel. It's NOT for everyone. It's fantastic for people that need range, torque, and reliability (assuming your HPFP doesn't quit and you don't mind filling up the DEF tank), but if you do a ton of short commutes, it'll punish you in the long run.

No engine worth having than the 3.0! Full of power and smooth.

4xe is a POS half assed EV. Terrible MPG on anything beyond 30 miles.

Has your fuel pump failed yet? How many miles in those 2 years? Wheeling tough trails or dd or mall crawling? The 2019 with the 2.0t ran tough trails all over the country, multiple 1k+ mile road trips, and was the wife's dd, all on 37s or 38s. 0 issues, 0 time in the shop. Unfortunately it was stolen with 64k miles on it. The 2022 is at 26k miles on the 3.6L same use case, now on 39s, again trouble free. An example of one 3.0ED without issue is pretty meaningless when they have a documented failure rate much higher than either of the others. Are their more 3.6L failures total, probably but they outsell the ED like 1,000-1.
