Isn't power relative anyways? I had enough "power" to pull a stump out. I had enough "power" making it through a mudhole that was fender high. I have enough "power" to haul a demolition job to the dump...

IMO power is relative to what is average for all vehicles on the road. The pentastar configuration in the Jeep Wrangler/Gladiator models seems behind the curve.

I think in 2025, it's disappointing for a manufacturer to produce a modern engine with less than 300HP.

Okay I get that, but the Pentastar gives you 285 hp. I would say in the manner in which I use my JT I've never felt a lack of "power." And I admit that could change if I decide to use it for a different application. But numbers are just that numbers. I work in the medical field, and we have a saying, "treat the patient not the number." Not that numbers don't matter but in the big picture if you focus only on the number, you can miss what matters most.

You are comparing apples to oranges. The perceived "power" you feel (or don't) is a product of the entire vehicle. Even with the exact same model/weight/engine/transmission gearing, factors like axle ratio and tire size have a huge impact on power.

A JTR with factory 4.`0 gears and 33" tires is going to feel more powerful than a Grand Cherokee with factor 3.45 gears and 30.5" tires, even if they have the same engine and transmission.

That's fair, your necessities might not necessitate more power but I'm sure that you wouldn't mind having more also, right?

More power and torque would satisfy a larger consumer base. Someone like me, who hated towing with the 3.6. Over 20 seconds to reach 60MPH makes merging an apologetic struggle, and being a road block to other drivers while trying to balance engine temps, RPM, and speed was a really bad driving experience.

"Move over and let faster cars pass" just restarts the struggle of trying to regain momentum. My strategy was to only pull over on the down-hill.

I disagree. And I think you are missing my point. From a purely physics stand point when measuring power you would take all those things into consideration. I'm merely pointing out that when I'm taking my loaded truck for a camping trip in the woods that frankly 90% of vehicles couldn't get to and I'm in the process of getting from point A to point B the last thing I am thinking is, "The JT sure doesn't have enought power." Like I said it's relative. If I was pulling a 6K lb trailer to that spot I might very well be thinking that.

My opinion could change if my use of application does, absolutely. And no I wouldn't mind more power and torque if it was feasible in the current rig I have now. But frankly I think if I needed something more than what I have now I would probably get a 1/2 or 3/4 ton Ford or Dodge.

My trailer only weighs 2360 lbs fully loaded for 3 weeks and the tongue weight is less than 50lbs. I can move the entire trailer in my garage alone, by hand, without assistance. I'm not making an unreasonable request. That's below the rated towing capacity. Our camping trips sometimes take us a long distance and there's a lot of road miles involved.

Last month we did CA -> NV -> ID -> UT -> CO. It took us 2 LONG days on the highway to get home after CO. Should be a 3 day trip with a 3.6L.

If you think the 3.6 has enough power, you've never driven the 3.0 diesel...
i have absolutely driven the 3.0 diesel. I was expecting this massive difference based on the kinds of comments people make on here and reddit.

Instead, i was met with an experience much more in line with the vast majority of 0-60 results that motoring mags publish, which is to say: the EcoDiesel is faster by an amount nigh imperceptible.

Did i feel a difference on the low end? Yea, sure. Would i prefer it if i were towing 3-4k on a regular basis? Absolutely. But there isn't one bit of objective measurement that says the 3.0 is markedly faster in stock guise with no trailer behind it, and the subjective "seat of my pants" measure agreed.

It's close to 1.5 seconds faster to 60mph which doesn't translate to much on flat ground until you're fully loaded and/or towing, where it's about 5 seconds faster to 60mph. Climbing hills is also where it's noticeable.

The HP numbers aren't that much different between the two but the torque is massively different.

That's a far cry from Motortrend's testing:

https://www.motortrend.com/reviews/2021-jeep-gladiator-ecodiesel-first-test-review said:
The quickest Gladiator we've ever tested, another base model Sport but one that was fitted with the gas V-6 and a manual transmission not available with the EcoDiesel, needed 7.9 seconds to hit 60 mph and 16.3 second to complete a quarter mile at 84.1 mph. This diesel truck got to 60 mph in 7.6 seconds and past the quarter-mile mark in 15.9 seconds at 86.1 mph

This is a common misconception about diesels. People always hear how they make so much more torque, so they expect them to be lightening fast, but they aren't. It's a different type of power, different type of torque. It's all low rpm.

When I first bought my BMW X5 diesel I was expecting it to blow the doors off everything else. Off the line it would destroy almost anything... until about 40mph then it tapered off and was really no different that anything else in its class. Try to shit can it at 70 mph and it was ok at best, but roll a little into the throttle at 70mph and it would pull away hard because the rpms stayed low in the powerband.

Really gotta understand how to use diesel power and stay in its torque band. It's not like a gasser where the more skinny pedal the better.

I didn't use motor trend's data. 0-60specs.com takes actual track time slips from controlled environments (NHRA tracks and other verified sources) and averages them.

https://www.0-60specs.com/jeep/gladiator-0-60-times


The average for a gasoline engine models is about 1-1.5 sec slower than for a diesel.
According to your own source, the fastest gladiator tested was a gasser...

Also... you may not use MotorTrend's data, but your source does.

Not a single one of the sources used by your source is NHRA or track slip times... they're all motoring mags.

Every single time is from Motor Trend, Car and Driver, or Motorweek.

'23 Jeep Gladiator JT - Willy
I drive my Jeep JT in MI greater Wayne County - I able to pass anything besides "suped up sports cars" just fine. JT is fine. If you want more power; which is a loose word to use. Then I guess you should of bought that Dodge Challenger Demon.
