Bought the simplest (no etorque battery and cooling lines) and cheapest automatic option available for my model year.

Since it is a 2021, had to have the 2.0T.

I really wanted 3.6 no-etorque auto, but that option was taken away in 2021. Having sald that I'm delighted with the 2.0, except that it sounds awful at start up, and barely OK once it warms up.

Until the 392 owner puts a K&N on his! Checkmate 2.0T owner :)
Sorry you’re wrong. It is a proven fact that the K&N filter addition to the 2.0l T provides an exponential power increase. Whereas the inclusion of the filter to the 392 is ONLY additive. Therefore, the 2.0l T will be at parity with the 392!

I think 2 things play a role in the 3.6 being more popular:

1. At least through the time i was ordering in 2019, the 2.0 was a $1000 premium which to some was a turn off and not worth it

2. Those who already had Jeeps prior to getting the JL knew the 3.6 has been around for a long time and is a very good engine.

my wife’s 2012 WK2 gas the 3.6 and through almost 150k miles has been a rock. To me there was no contest between the new 2.0 vs the true and tested 3.6 when placing the order.
I think you're right. But when I read the forums and see videos on YouTube it seems like the 2.0 is more common.

i wanted something different in a Jeep that i never had so Diesel 3.0 fit the bill with a really different power delivery . also you get the Dana 44's 210 front 220 rear axles and the 8hp-75 transmission

If the diesel was offered with a manual I would have considered that. But as we know, only the 3.6 was. Not that it is a bad engine; it has a proven track record and has decent linear power over 2K rpm.

I think it would be interesting to do this poll again in a year. I think the percentage of 2.0's and PHEV's will be much higher.

I can see PHEV sales growing; it is brand new. But what makes you think 2.0T sales will grow? The motor’s been out for awhile now.

The 2.0T is now the standard engine with an auto transmission, the 3.6 is now a premium option. I think people were skeptical of it at first but as time has passed it has proven to be reliable and make plenty of power. I also think they are making a push for the 2.0T to be the future of the wrangler and phase out the 3.6

I don’t know why FCA offers two mainstream engines. Output and efficiency of the 2.0T and V6 eTorque are virtually indistinguishable.

I believe FCA’s main goal to offer the 2.0T on JL was to grow Wrangler sales overseas, where tax laws tend to penalize larger displacement engines. But that hasn’t really materialized; 80% of Wrangler sales remain in N.A. The fact is the 21/24 MPG numbers of the 2.0T are simply not good enough for overseas buyers.

I would like to see FCA replace the 3.6 V6 with a 3.0T inline six. That would place the six cylinder above the 2.0T in power output, and below the 392 HEMI.

PS - the 3.6 V6 isn’t going anywhere; the all new 2022 Grand Cherokee uses the Pentastar V6 as standard motor.

I'd imagine that the main answer is simply cost. To replace the 3.6L entirely with the 2.0L, they'd have to re-tool not only the 3.6L plant, but all the suppliers of 3.6L parts as well. That's a big investment, and typically automakers will only do this over time.

I drove both engines but wound up getting the 3.6L eTorque. As an ex engine design engineer the newer technology doesn't worry me much. What was more on my mind was simply that the 2.0 was built in Italy. If it was built in Germany, I would have gone that route for sure as the engine felt spirited to me and would have appreciated the small bump in fuel economy.

What is significant about the countries for engine choice?

Some countries are limited to 2.0 liters, or they face massive fines. So, you see a lot of high powered, multi-turbo 2.0 liter cars out there.

At 344 votes, the poll shows what I thought...3.6 dominates 2.0 by 2 to 1. The others are a low percentage. I would have liked the gas mileage of a 2.0T, it's what's in my GTI, but known carbon buildup issues and lack of manual transmission made the 3.6 an easy pick for me.
