Gladiator vs 1500 MPG

[ShadowsPapa]

Correct. My '23 Grand Cherokee averages just over the 23-mpg on daily drives. On a recent open road trip to Michigan's Upper Penisula, I was able to hit the 27-mpg mark. Quite impressive considering the powertrain similarities.

Even if the OP doesn't want to hear the "driving a brick" theory, there is much truth to it!

Not a thing wrong with the GC, it just wasn't purple!

Great to here I sold both my 3.6 i had personally and switched to the diesel only have a 12 jk with 40 k miles on 35's now with a 3.6 its never seen over 19 even stock

My overland when stock did 22 pretty easily.
Every change I made dropped that a bit.

Okay but if two JT’s are traveling at 26.5mph in opposite directions with a crosswind of 1mph how long will it take a freight train of Ram 1500’s to expend the same amount of fuel as a bicyclist pouring kerosene on the street at 1 gallon per hour while completing their paper route in Idaho Springs, Colorado?


(Did I match the vibe of this discussion? I feel like I nailed it)

It only takes 14 crabapples. Trust me.

5 hours because penguins can't fly.

If a hen and a half lays an egg and a half in a day and a half, how many flapjacks does it take to cover a doghouse?

My 21 GC-L with the 3.6 gets lowww 20s on the interstate at 75ish. I'm guessing due to the full time 4x4 transfer case?

I was pretty disappointed, i figured it would atleast match the 23-24 the Town and Country we had the family in before got.

Anything at that speed will do piss-poor. That's just how it is.
And no, it's nothing to do with the transfer case. Even in the 1980s AMC found that the difference between a FAD and 2 WD option and no FAD and full time 4x4 in the Eagle was UNDER 1 mpg so they saved their money. On a modern vehicle with better drivetrains it's going to be less than 1 mpg for sure.
Doing 75 is what's killing mpg, not a transfer case that's likely running 2wd unless it senses traction loss anyway.

My other similar anythings have not been so piss poor. I would have definitely sprung for the proper transfer case if it was available on any of the lower trims, we got the limited.

Transfer case won't make but maybe 0.7 mpg difference and that's assuming front axle disconnect and a true 2 wheel drive option. People have tested these JTs and JLUs with the Selec-Trac transfer case in 2wd vs. 4 high auto and found no real difference.
That's why 4xe owners drive theirs in 4HA all the time - it won't limit torque and they've found no difference in mpg.
So no, don't blame the transfer case.

There is no FAD with Quadra-Trac I. It's full time awd. But it doesn't matter, I'm not here to argue. i too assumed what you said when i bought it.

I have no trouble hitting the 17/22 range. Usually closer to 18 in daily driving . 21-22 on interstate. Sport S / 6 speed MT. Did a couple mpg better before I bought the Rubicon take off wheels and Falkens.

 

[RichDSport]

My Auto Rubicon on stock tires averages around 16, maybe 19 if it’s all highway under 70mph. The Front end treatment is a big factor I think, along with the size of the tires. There’s no fairing for the wheels. Also obviously the Rubicon rear end is not terribly efficient. My soft top is like a mini sail. The EPA numbers really only apply to Sport versions. I definitely wonder how much better I could do with a 1500 on MPG, since I’m either towing or doing errands 95% of the time in the Gladiator.

I wonder what folks who own both a gladiator and 4 cylinder Wrangler Rubicons are normally seeing?

 

[Empty Pockets]

RivhDSport- good points for sure. I dropped a couple MPG when I put on the Rubi wheels. I never considered that I also installed a Rubi steel bumper around that same time (thus loosing the little filler fairings between the bumper and fender) and installed my old trusty Warn M8 (more weight) so there are factors I should have considered. All in all, I’m not disappointed. My old truck, a ‘15 Silverado with auto and a bigger V6, did better- but it was much more streamlined, 2WD, and not as enjoyable.

interestingly, I installed a RLD cap not long ago (200 pounds, I’d guess) and picked up a reliable 1 to 1 1/2 MPG.

These are 2 trucks from the same company with the same engines, and the heavier one gets better MPGs fromn the same BS methodology

Here's another data point: my 2020 Gladiator gets about mpg better than my wife's 2022 JLU, no matter which one of us is driving - both have the 3.6L/8 speed; the only difference in the drivetrain is the gear ratio: mine is 3.73:1 while hers is 3.45:1. Going by gear ratio she should get better mileage than me, but it's the other way around.

It's where it places the engine in the RPM band for THAT engine. Load on the engine.
If the engine is running too slow, it's got more load, more heat rejection, less MPG.
It's doing to depend on how fast each is typically driven as to which gets better mpg. You are likely talking generically or average and so on - I'd bet that there's a range where the numbers would flip.

My Ecodiesel willys dropped 4mpg on my work commute 24 -20mpg with a aev dualsport lift and nitto ridge grappler 35s. Stock gearing. Mostly in town.

How do you like the 23 Grand Cherokee? My wife traded her great 21 for a JLU because she wanted purple LOL.
Not a thing wrong with the GC, it just wasn't purple!

Really enjoy it. I had the previous generation (2014) and loved that as well.

This current WL takes it to another level as far as refinement, power and luxury. I have the 2-row Overland package. Even though the power and torque are similar to the previous gen, I feel that it is snappier. The air suspension in the Overland results in a heavenly ride with vehicle height adjustability for my wife to enter/exit with her physical limitations. I also use it to level my towing angle (depending on which trailer I have hooked up).

Yup, no purple available!
