Why Wrangler doesn't get the 5.7L option?

[Willys.JLU.2021]

Dont they have to go through the same sh!t just to sell a hand full of 392s. Sounds like it would be worth while to sell a lot of 5.7s

Good point. The V8s get better MPG. So why is the government favoring a 3.6 over it ? My 1995 Impala SS with the Corvette (RT1 ?) got 25 miles per gallon highway 30 years ago. Gas mileage hasn't improved 1 MPG in 40 years! My 1985 CJ-7 got 20 highway and 17 city. 40 years later (WITH START/STOP) My 2021 JLU gets 20 mpg highway and 17 city. CAFE is a bunch of BS and probably increases the price of a Jeep by 5k minimum. The 5.7 at a 4k premium would increase Wrangler/Gladiator sales 100k plus the Gladiator is under powered w the 3.6.

Simple answer - it takes an enormous amount of effort and cost to certify, at the federal level, drivetrain choices offered in vehicles sold in North America. Stellantis has laid off a lot of US based engineering resources and the ones that are left (and the ones outsourced overseas) are trying frantically to get the Recon launched (one year late), the 4xe Gladiator (should be easy, right?) as well as the upcoming replacement for the JL Platform.

Sorry mate,. ain't going to happen.

But they sure got the 5.7 back in the Ram 1500 awful fast and certified.I dont think that will be the reason they don't do it. But we all know they would sell a lot of Wranglers w a 5.7. Keep hope alive.

Hi,

Believe it has more to do with vehicle classification, trucks have less stringent emissions than a station wagon/ car as believe that is what they classify a Wrangler.

Yep, and they cannot yet produce enough 5.7’s to meet the Ram 1500 demand. … they have already said “stay tuned” for the 5.7’s return to the GC. The Wrangler is not at the top of the list.

Could be. But as was said by someone else on here, Jeep has already promised the 5.7 will be back in the new Cherokee. Is that a wagon/car? But maybe im wishing for something that will never be. Oh well you are most likely right..

True but by the time the J70 comes out in 2028 they might have caught up with demand and make it an option in the J70. Too much demand. What a problem to have. If there is too much demand that is telling Jeep what they should be doing. I man can hope

It takes time to re continue the all but abandoned V8 program. Plus IIRC from articles the same plant is now also producing the T-6’s. One article was extensive giving numbers on Ram wait times, expected ramp up times etc.

Understood. Honestly, the Hurricane 3.0 in the Wrangler would be second best thing. We will see..thanks

Are we trying to argue that the 392 puts out less emissions than the 5.7L also? With the moab and willys 392s they are clearly trying to move a lot more v8 Wranglers than they did before. It's not emissions or ability or weight or any of the reasons that have been argued. It's supply and that's it in my opinion. And even if it's an SUV emissions thing, why doesn't the JT have the 5.7L then?

I doubt there will be a J70 in 2028, if at all at this point. I believe the Recon will be the market test for whether or not Jeep foolishly puts all of it's eggs in one basket, that being EV/ERPB. That having been said, I also believe that the very much full size Scout will fail for the same reason, a lack of buyer interest in a vehicle that should be simple, but will in fact be very complicated.

Now, I don't mind if the J70 makes it to production, as long as it isn't a replacement for the Wrangler. I don't see it performing well in the market though, as it would have to come in priced above the Recon, which starts at about $65k. Be careful about what you get excited for.

As for the 5.7, no real need to certify it, as the 392 is essentially the same block. It will fit easy enough. It would just need EPA certification. Crash tests on the 392 would be the same. But, as said, the demand is too high. But I think a 5.7 Gladiator would be a game changer for it. Because then it would be able to tow a decent size, boat, camper, or utility trailer.

I think one of the key reasons is that the Wrangler isn't designed to handle the stress and heat put out by the 5.7L engine, unlike the Gladiator which has a more robust design to accomodate it. The Wrangler's frame and transmission are just not built with that kind of power in mind.

Explain better please. For those of us that don't know about these things..

The 392 got a little bit of frame strengthening and that's it. The 5.7L weighs about 50lbs less than the 6.4L. The pentastar is only ~100lbs lighter. It's not nothing but the EcoDiesel weighs more than the hemi's and makes similar power to the 5.7L (less hp but more torque). It's not a frame or weight or agility issue as proven by the various JLs that have been available already.

The cab forward is the same frame and the JT has the same cooling system. It's an entirely made up argument. And the EcoDiesel made more torque and way more heat than the 5.7L, not to mention the 392 Wranglers exist.

To my understanding the J70 is a replacement for the JL just like the Jl replaced the JK and the TJ replaced the YJ. The Wrangler will live on im 100% sure of that. Worst case the 6 cylinder Turbo will help the underpowered Gladiator and give the Wrangler a boost

They would have to discontinue the 392 if they brought out a 5.7. If it was priced well I’d consider upgrading from my 3.6… maybe.

Good point. The V8s get better MPG. So why is the government favoring a 3.6 over it ? My 1995 Impala SS with the Corvette (RT1 ?) got 25 miles per gallon highway 30 years ago. Gas mileage hasn't improved 1 MPG in 40 years! My 1985 CJ-7 got 20 highway and 17 city. 40 years later (WITH START/STOP) My 2021 JLU gets 20 mpg highway and 17 city. CAFE is a bunch of BS and probably increases the price of a Jeep by 5k minimum. The 5.7 at a 4k premium would increase Wrangler/Gladiator sales 100k plus the Gladiator is under powered w the 3.6.

40 years ago I had an 83 F-150 with a 300 and AOD that managed about 14 mpg and wouldn’t pass a Yugo. Now I have a 2019 F-150 with at least twice as much hp that gets around 21-22. I think things have changed a little.
