The 10 harsh truths Jeep didn't come out with a V8 Jeep gladiator.

[JmattNYC]

I've always said Stallantis is The Gladiator worst enemy and is holding it back. That 2021 merger with the euro globalist corparation, EPA mandates(Green Fraud) and all that EV bullshit they wanted to push onto us really hurt the development of drivetrain options. We are stuck and hopefully that changes very very soon.

Yeah, I’m fine with the EPA and the clean Air Act. I sort of enjoy air that isn’t crunchy and water that doesn’t catch fire.

People opposed to these things tend to be from places with low industrial density, low population density, or are too young to remember how toxic and polluted our country had become. The last time the air and water were this clean was prior to the industrial revolution.

I live where we had coke ovens and steel mills. We still hate the EPA for some of the shit they did.

Just redesign the 4.0 I6 and throw a turbo at it. I’ve looked at the 2.0t a little bit. It’s cool but I’d like to have at least a 6 cylinder in a gas truck. I’m fine with the 3.6 for now. Don’t see myself going for a 5.7 any time soon.

So where did you grow up? People in favor of overzealous environmental regulation tend to be from overpopulated city's.

I do, and that’s why my Gladiator will be my last modern car. Every week I’m online shopping for a low-mileage gem that’s 30 years old at a minimum.

Your truck does the same things, reports your location, telemetrics, even your phone’s contacts to Jeep so it can be packaged and sold.

They can take the data I give them BECAUSE

- Never touched the "accept" icon when the radio boots up. (Legally this permits it, especially on the MY24+)
- Not allowed data sharing in the radio, via device setup (contact, messages, etc.)
- Disabled/turned off those settings in iOS (more privacy rights than Google/Samsung devices)
-- Also running an old Beta of iOS 18.4 (doesn't violate privacy like iOS 26+ does, and can go back to iOS 17 if desired.)
-- Separate accounts for personal data vs accounts I use for music or maps, which is all I use my phone for in the JT. I also avoid using Apple/Google maps when possible.
- And have pulled the XM and Cellular antenna from the radio, so they can't update or pull data (Non-Nav radio too).

This is one of the reasons I stayed away from the 22+ as most of them had either the 8.4" radio (usually Nav, and other data features) or more bs for using your phone. The 24's were really nice looking, until I found out the bigger 12" screens: force ads and force updates. That's one reason the 4xe people got their Wranglers bricked or caught fire, forced updates OTA.


If I don't actually OWN my product, then I won't buy it. If BUYING isn't OWNING, then PIRACY isn't THEFT. If MY PRIVACY isn't PRIVATE, then REVERSE ENGINEERING isn't HACKING. If FREE SPEECH isn't tolerated, then there is no FREEDOM.

Excuse me? Maybe the west coast doesn't know how bad those rural areas get affected, if you aren't...it's due to those high density population/industrial areas that were allowed to pay fines instead of FIXING their emissions output, which went into the atmosphere and dispersed across the USA and world. Like China, who outputs more emissions globally than most other countries combined.

No, it's not just "people from places with low industry or population or those too young to remember". And name one NORMAL place where the town isn't corrupt af and the water ignites. Because if your local gov allowed fracking, that's NOT NORMAL for intelligent/uncorrupt people.

The EPA only runs off of lobbyist backed choices. Really, go research it.

The 4.0L was not a good design other than being a straight 6. Poor main supports, poor seals, and compared to other straight 6 engines of the time, performed worse than most. Saying the 4.0L was a good engine was like saying the 3800 from GM was a good engine, better than most, but not great.

From a VE standpoint, any engine should have 2 cylinders for every Liter of displacement. Go smaller, lose efficiency. Go bigger, same thing but gain low/mid TQ.

California people took offense to this.

Also, the Dunning Kruger Effect is strong in those who watch the news and parrot vs educating via reputable scientific sources and common sense.

Shit, I forgot "common sense" isn't common in the last 20 years.

Clean air act is a great thing. I grew up in Bushwick Brooklyn,NY where the asthma rates for low income people were off the charts in the 70s/80s/90s. Some of the revision have help cleaned up toxins, remove garbage burning from buildings (Special permits only) and improve air quality for the next generation. My problem is when they were weaponized to do bidding the bidding of the demonic globalist and began heavy hand tatics against our people. That is no beuno.

The reasons so far in this thread are more valid than most of that video. It's also the same reason why they stopped offering the Gladiator with a manual transmission, not that people didn't buy them, they didn't make up enough of the sales to be worth it to investors, regardless if they still offer the same option for the Wrangler with the same powertrain.

The 3.6 CAN make better power, just not quite how the EPA (let's be honest, Cali) wants engines tuned. There's a reason people like Livernois Motorsports are making 20+hp with a retune (just an easy reference).

Also no one discusses FI (mostly turbocharging) for a couple reasons, mostly down to cost in the end. You can say they aren't reliable, yet most don't want to spend on forged internals to handle the boost they seem to want. This isn't just a Jeep thing either, you build your engine for the load you'll put on it. So in the end, COST = reason for most people.
-I'm not (generally) a fan of supercharging, so I'll leave it to this: they have similar issues to turbocharging in terms of tuning, and their own drawbacks such as power loss/gain ratio and increased crank wear over time (by design).

Expecting 100+hp from a stock engine that's built on a budget to pass emissions, after pumping 12+psi into it and not having a safe tune, or at least the ability to take full control, is insanity. Go slap a 100+hp turbo on a stock MODERN civic, or wrx, non-ecoboost v6 mustang, or camero...they'll blow up too.

These aren't built for power as is. And as such you will need to upgrade parts to handle the power you want from a modern vehicle. You do this for off-road, why not for power too?

The engine can handle mild boost, it is the valvetrain that struggles to keep things together and there are not enough diagnostics to definitively tell you things are going south. On top of that jeep detuned the diagnostics so a stock engine could make it out of warranty before you noticed the intake valves are not opening all the way. A 5.7 with E-torque would be an ok world powertrain, and would give the gladiator some guts to match its exterior.

This is what I’ve been saying. An updated inline 6 with a turbo would give just enough performance increase to satisfy the super majority of people, while also increasing reliability, and possibly even gas mileage.

 

[Stormtroopin]

Ok I’m gonna say something not very popular. That is why would anyone want a V8? Their heavy as a Hemi is built out of cast iron, with the truthfully one cool thing is sound. Mileage goes away as soon as tires over 32/33” are used with any engine. But Jeep has developed an incredible engine lately with granted a short record. But the 2.0 Hurricane in the latest Grand Cherokee, with 324hp/332lbsft tq, at a considerable weight savings, plus mileage increases across the board. In a clean sheet engine design that has been built from the bottom up with the best technology available today. Like in the Grand Cherokee, leave the 3.6 as the standard, but offer the 2.0 across the trim levels. I say this only after taking a ne Grand Cherokee for a nice ride with a friend who just bought one. Who told me about the test drive in a 3.6, but then a 2.0, that was just an eye opener! Not quite as smooth as the 3.6, but with twice the power at half the rpm, not peak power at high rpm’s, but the equivalent at 2,000 in hp and tq being twice. Seems like a good deal in a mid sized truck.

Big tires and small engines = terrible MPG. However the 5.7 with big tires also = terrible MPG….if I’m gana have terrible MPG give me the roar of the v8 over any small block+turbo….

While I agree with you, you can make some good numbers on an inline 6 turbo charged but still not drink like a V8 does idling down a trail. Thats what I primarily think of when I’m talking Jeeps and engines. Does it throw down torque on demand and what does it do when at idle? A turbo on the smaller scale will spool faster to provide the power you need for those certain obstacles that need the oomph but not swig gas when you’re waiting to pull up on the obstacle. Maybe something around a T3 size would work. I’m not sure what has gone on in turbo technology in the last decade or so as I’ve been out of it since around the R34 Skyline time frame.

Do you know much difference in fuel use? Maybe 1/2 gallon per hour?

You guys are literally just describing the Hurricane engine. That's what that is. It exists.

I have a supercharger on my 4.0 in my TJ and I get about 8 mpg on premium and it drinks a gallon of water/meth probably every 50 miles although I've never measured. Love the engine for it's durability and characteristics but it is not an efficient engine.

There is plenty of argument for a straight six being the best engine configuration. And again, we loop back to the Hurricane. A modern engine with modern shit bolted to it but that's a twin turbo 3.0 straight six.

 

[BlueScapegoat]

The 4.0L was not a good design other than being a straight 6. Poor main supports, poor seals, and compared to other straight 6 engines of the time, performed worse than most. Saying the 4.0L was a good engine was like saying the 3800 from GM was a good engine, better than most, but not great.

Poor main supports? People stroke those engines and boost them and I've never heard that cited as an issue. Is it? The only seal issue I'm aware of is that stupid two piece rear main

 

[Walldo]

Lets face it, Jeep didn't look at any other powertrain options cause they know that people will still purchase it no matter what engine they put in it.
