Gladiator vs 1500 MPG

[Jrap]

lol the laws of physics say otherwise.

What about the 300+ pound advantage of the Gladiator? No physics in that?

You‘re not getting 17/22 on a vehicle you’ve added a steel bumper and winch to?

Vehicle weight has nearly no effect on actual steady state fuel economy, even then it typically takes very large changes in vehicle weight (300 pounds on a 6k pound truck is nothing) to have a noticeable effect.

Ram uses a mild hybrid 3.6 etorque setup you gain a couple mpg, 12hp and like 40 lb-ft of torque.

Not talking steady state, talking city start and stop. Ram 1500 heavier by 300+, same engine, gets better city mpg in start and stop traffic where 300 lbs should come into play.

Internet says etorque adds .7 mpg, so it helps, but doesn't fully explain. Nice answer!

Dude, not talking about my vehicle, talking about 2 stock vehicles and their MPGs according to their window stickers

Even then 300 lbs is negligible. You are talking 1-2% mpg at most. Compare that to aero that can easily cost 20% or more mpg

300 lbs is exactly 6% extra weight

Sure there is. But the truck's weight has nothing to do with your claim that physics don't apply at 5mph ?

I had a fully loaded 2020 ram rebel with a 5.7.

I got the same 12 to 14 miles a gallon in that that I get in my Gladiator with the 3.6.

Because of etorque. Here’s a comparison, left one has etorque and middle doesn’t. Compared to a non etorque 1500 the JT is 1 mpg better in city and 1 less on highway. 1 less on the highway is because of gearing.

Maybe some don't realize this but the "city driving" isn't what you think it is.
The test's average speed is 21 mph, it's a dyno test about 11 miles long, takes just over 31 minutes to complete, involves 23 stops, reaches a top speed of 56 mph.
So that 5mph is out the window. Yes, drag will factor in, and like I posted before - the EPA even says the drag of cargo on top can drop CITY mpg up to 8%. That's almost 2 mpg if you usually get 22 mpg in town. So can't say drag doesn't matter. And factor in that the EPA testing is up to 56 mph with an average speed of 21 - yes, there's drag.

And if RAM being compared is e-torque, then there ya go.

EPA city mpg test gets up to 56.7 mph and roughly 15% of the test is at or near those speeds.

Meh, so I rounded and pulled from memory ?

The EPA doesn't actually test most vehicles, they take the manufacturer's word for it and do spot checks.

I haven't read every post in this thread, but if it's comparing a 3.6 JT with a 3.6 e-torque RAM, it's a big DUH on the differences.
