Gladiator vs 1500 MPG

[Gren71]

@Jrap

Man…it seems like you either have the answer yourself or are just baiting people by denying or shooting down every possible reason presented.

We may as well say they get different MPG because FCA wants to make people wonder why they get different MPG. Or maybe the earths poles shifted between the tests, or perhaps it was particularly humid on one day of the testing. ?‍

All of the reasons given (not mine) have been well thought out and logical answers….if they’re not good enough than PLEASE share your theory for the difference.

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?

I hate word problems. ?

I normally average 22 to 23, but its mostly highway. I think the big difference is probably gearing. I think the ram is geared for better mpgs.

Wow thats awesome i sell alot of 3.6 Jeeps have never heard of one averaging that much usually 14 to 16 stock whats the secret?

Well, heres how I see this problem.

This is distracting information meant to muddy the waters

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?
At what unit are we measuring fuel? Calories perhaps?

next we need to figure out what the average length of a bicycle paper route is, and at what speed a bicyclist would travel while pouring a liquid.

presumably the route could be the distance in miles of an average neighborhood in idaho springs Colorado. And the speed could be assumed to be the average speed of a teenage cyclist.

then we can calculate the calories needed to travel that distance and speed.

Assuming the train is traveling the average speed of a freight train and has the same weight as an average freight train of 3,000 tons it takes 0.48 min to expend a gallon of fuel. A paper route probably takes 2 hours so .96 minutes to expend the same amount of fuel as the person on the paper route pouring kerosene on the ground. But i don't know how long it takes to do a paper route in Idaho Springs Colorado so lets just answer 0.48X were X is the ammount of time in hours it takes to do a paper route.

So that has an answer but I'm not sure there is an answer for the op as he stated aerodynamics don't exist.

So are you not questioning the published MPG's:

No, I was not questioning the published MPG's.

Or are you questioning the published MPG's?

I was questioning why under the same EPA testing methodology (I.e. the published MPG's on the window sticker)

They got different MPG ratings because they have different levels of efficiency. Like you have been explained, there are many factors that go into it beyond the engine used and the vehicle weight. So what are you getting at? Do you believe, or not believe, the numbers?

EPA does controlled testing, it's very methodical and repeatable. So it seems silly to me to suggest they're not methodical.

Doubt there's been any study on this sort of thing...

That's exactly what the testing the EPA does is. It's a study on a vehicle's efficiency...

Arguments can be made that their ratings numbers might not reflect real-life driving results, but that's not the point here. Apples to apples, car to car, they give you an efficiency rating. The 1500 is simply a more efficient vehicle.

Grand Cherokee gets far better mpg than the JT and yet - same engine, same transmission.
They have different tires, there's a lot less air getting under a GC than a JT, the fenders on the Grand Cherokee don't act like big air scoops. The weights are similar - proving that shape and height does matter.

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!

 

[The Duck of Earl]

Clearly the OP never did the pinewood derby. Aero is a big part of this. Can't believe this is even debatable.

Wow thats awesome i sell alot of 3.6 Jeeps have never heard of one averaging that much usually 14 to 16 stock whats the secret?

I use the ACC a lot, but other than i dont do anything special. The bed is full of tools too. My best average was 24.9 on my old tires and that was with 7.5k miles averaged.

Last year, I did 12 hours round trip at 70-75mph and averaged nearly 24. Sport S with the stock 245/75R17 Bridgestone A/T's, 3.73 gears.

Did the same trip a few weeks ago having since added Rubicon springs/shocks and Rubicon-size 285/70R17 load C Toyo A/T3's and averaged about 20.

 

[Jrap]

i got my answer as concluded in post #41. anything else happening here is where ya'll take it

 

[Orange01z28]

Why is it that a 3.6 4x4 Ram 1500 is rated 19/24 MPG and a 3.6 4x4 Gladiator is rated 17/22? The Gladiator weighs several hundred pounds less. Please don't say aerodynamics because that is negligible in city driving. Both have the same exact 8-speed auto transmission. This makes no sense whatsoever! I guess the cold water on all this is who the heck is even getting 17/22, because I'm not. No, I didn't buy my Gladiator for the MPGs, just wondering what the heck.

I had both with the same exact drivetrains outside of the rear end and rear end gearing

The tune is different, and the Ram has the e-Torque as opposed to the Gladiator's ESS.

In the real world, my JT got better mileage than my Rebel in the few weeks I had it stock

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

Wow thats awesome i sell alot of 3.6 Jeeps have never heard of one averaging that much usually 14 to 16 stock whats the secret?

Both our 3.6 jeeps get right around 19-20 almost everywhere, whether in town or on the highway
Have seen 23's on very long rural runs where we can stay around 60-65 mph.
They will both also drop into the 18's on the highway above 70 mph.

The Wrangler got a little better +1-2 mpgs in some instance with the stock wheels/tires, before I added the Rubicon take offs. It was more of a 20-21 almost everywhere stock.
