I'm sure 0-60 in 4.5 seconds is real useful during rock crawling. Or mall crawling for that matter like 90% of them will be driven. If they had some sense they would put the Cummins under the hood.

I have 4:1 and it’s annoying not locked in 4 Hi but over geared in 4 Lo … waiting for a guy at work to test his black box solutions and can also kill the SS on the engine …

that is indeed one problem but again it’s also because the things are heat machines.
having the blower on a clutch keeps the charge cooler at idle and gives the ecu the ability to completely cut boost when there is no more timing to pull. very handy when you have an IC cooling failure or soak the crap out of it just driving it flat out for miles.
A Cummins? A giant heavy cast iron monster with modern day emissions equipment? No thank you.
15 years ago I rode with my friend in his then new Wrangler Rubicon from Columbus, Ohio to Austin, TX. What a miserable ride that was. Cramped and noisy. Why anyone would want one of these as a daily use vehicle is beyond me.
If I wanted one to go offroading as a weekend-only type vehicle, I'd get an old one and drop an LS or a 3rd gen Hemi in it, then put a positive displacement supercharger in it if I needed more torque for rock climbing. But the supercharger would defeat the purpose anyway, you climb rocks with low gears, not brute force.
So the 2021 392 version goes 0-60 in some really fast number. Who cares. You could probably do it faster in the cheapest V8 Camaro, Challenger or Mustang you can buy and you have a vehicle that is enjoyable to drive and comfortable to boot.
Really dumb vehicle. Exercise in marketing for all the pre-pubescent boys to ooh and ahh over.
What's next for FCA, I wonder. Put a Hemi in the Fiat 500?
They should do something smart that might actually appeal to a broad range of customers, like bringing back the Dakota. It's working for GM and Ford having a mid-size pickup. They'd probably sell 30 or 40 times as many of those as they would a 392 Wrangler.

This is why
You really want to drop 70k+, only run 13s and get bullied by a rental mustang gt? Really? The hellcat motor would give it very respectable performance, more than enough to trample all over the overweight G63 and run 11s.
It would break the internet and be the new flavor of the month in every gated community, but again somebody at FCA realized it’s a recipe for disaster and lawsuits. This is a very conservative choice, not the powerhouse i’ve come to expect from SRT.

Here's my perspective as wanting to buy a Camaro LT1 6MT in the next year or two. The budget muscle car would out accelerate and handle the Jeep as well as cost half as much. You open it up in a camaro and everyone thinks you want to race or are racing/are a bad person. Nobody looks twice at hard accelerations in a Jeep. I doubt people would want to race you. You blend in as just another Jeep guy. I like blending in.
You have the "loafing around" factor. A JL wrangler can move around well with the pentastar but you do need to work it. A burly 6.4 would be under light loads and live a long happy life in this thing. I like big engines that effortlessly move the vehicle around.
Longevity Factor. I'm in my 30s and hopefully will live for many more decades. What is the usefulness of a 392 wrangler 20-30 years later? Camaro could last long as well but serving a more narrow scope of a sports car/on road only platform. We see very old jeeps/4x4s still running with dinosaur power plants from the 70s. How well can this 392 hold up with very good care over the next several decades? With my use level of about 5,000 miles a year per vehicle and good care, hopefully a very long time.
Long term Resale Value would probably be exceptional in the 392 Wrangler because its a Wrangler and the days are limited of being able to sell big V8s. We all know they are almost out of the market for small engine and EV alternatives.
Would i ever care that somebody in a 4 cylinder mustang ecoboost could out accelerate my *theoretical* Wranger? Nope. Even my Alltrack could be modified to beat it in a quarter mile. Or if i bought a Camaro ZL1, would i care that a Tesla easily ate my lunch at the drag strip? Nope. It's comparing apples to oranges.
Hellcat Wrangler wouldn't be worth the extra ~$18k the hellcat versions typically add onto a 6.4 model, at least to me. Much in the same regard the ZL1 is not worth the large premium over the base V8 Camaro. Just my points of view.
I don't think anyone with a Wrangler wants a V8 to get a faster quarter mile time. They want the V8 so they can run giant tires and not have to drop 2 gears in order to climb a small hill.
I really hope I never grow up then. The wife and I really enjoy our overpowered bikes and cars...
There is a bypass valve that the ecu controls electronically to adjust boost. The bypass valve is actually a tigershark throttle body that was adapted for this application.
Something like this is more to my interest. But I'd still prefer the manual trans, a little more stealthy exhaust note, and no badges announcing what it is.
That being said, having a factory V8 eliminates a lot of the conversion work issues.
hellcat shortblock conversion with a brocharger can certainly be a winning recipe
So COVID has a 99+% survival rate for those under 35....
Under 35 drivers in This 392 Jeep won’t even come close to that high of a number!

Not sure about the Cummins, but I think I know where you're going with this. The VM diesel was a real turn off when we were considering a GC equipped with it. There has to be a better choice for a diesel engine than the 3.0L VM diesel they offer it with. Flame suit on.
The last V-8 “Wrangler” type Jeep was the 1981 CJ with 124 HP. However, it looked cool when lifted and equipped with long tube headers that were visible in the wheel well.
I have the 4 banger VM in an old Liberty and it's still going strong. The newer ones are even better I've heard.
