The EPA just released its ratings for the 2025 Ram 1500, and there are some big surprises. Contrary to expectations, the High-Output Inline Six gets worse fuel economy than the outgoing 5.7-liter naturally aspirated Hemi V8. Similarly, the Standard-Output variant of the 3.0-liter twin-turbocharged inline-six Hurricane engine only surpasses its predecessor on the highway. And the V6 is still the most miserly of the group. However, there are silver linings to these findings.

Comparing the HO Hurricane against the pedestrian Hemi is not really applicable. I mean, seriously, it takes fuel to make HP so one would expect a higher HP engine to get worse mileage, all else being equal. Be more equal if they compared it to a Hemi with similar HP. I mean 540hp vs 395 hp and the HO Hurricane is only available in the 4wd trucks, bet those Hemi numbers aren't in 4wd configuration.

I believe Mark Twain said, figures don't lie, but liars figure.

I can see a Ford F150 3.5 Ecoboost debacle coming....look at all the HP, look at what you can tow with it.....followed by failures and unhappy buyers looking for an out.

I've owned quite a few 1500s with stock 5.7s and various engine swaps and the 6.4 SRT8 engine swapped 2011 got the best MPG of them all.

Also people should not be surprised the 6 cylinder gets worse mpg, it was built because some stupid engineer convinced em they needed new technology to get past emmisions (Chevy and ford have no problem getting pushrod engines past emmisions). And on top of worse MPG it needs premium fuel vs the hemi being just fine with low grade.


I am not causing global warming, I am just trying to hold off a impending Ice Age!

A buddy recently traded in his 2019 Ram 4X4 for a 2023 Bronco with the 6 cylinder ecoboost. Nice vehicle, but he jumped on it before doing his homework. The Bronco has a max towing capacity of 3,500 LBS, which is pretty close to the weight of his boat...maybe less.

Even the 420hp standard one gets worse mileage except when going down the highway off the boost. They could have easily got the 5.7 hemi to 420hp.

HotRod I also had a 392 hemi, it would get 28mpg in 4cyl mode and even climb hills like that (was a 3.2L 4 cyl afterall)

My guess is that if you drill down to the detailed emission numbers the Hurricanes come out better than the Hemis.

That is really what drives most all drive train decisions in my opinion.

After owning an 85 Shelby Charger that you could only run premium in and only use Mobil 1 oil I will never own another vehicle that requires premium and special oil to drive daily, especially at today's prices! tsk

This is my concern too.
Meanwhile the EPA ratings are determined with some weird academic drive cycles, so I'll be waiting to see how real world abuse turns out. Plus the article states the mileage was achieved on 92 octane.

As a sidenote, I had a 96 Neon that got best summertime mileage on mid-grade, and wintertime did best on regular.
Maybe the constant AC use triggered different timing maps or something.

We need to get one to Rhinodart stat. We'll know the story within 30,000 miles.

It’s a joke to get better emissions and worse fuel economy- more fuel burned is going to be more volume, duh. But such are gubmint central planning outcomes. Hey at least the sample sniffs a little better.


I want my fair share

All they have to do is pass the test. The footprint of what it takes to get there doesn't matter. Diesel emissions are a prime example. The carbon footprint from millions of DEF plastic jugs stuffed inside cardboard boxed cannot be good.

let's see...............bigger, heavier vehicle, smaller engine.........less fuel economy ? haha haha haha
reminds me of the dodge 4x4 i used daily when i was a junkyard owner years ago...........
fabricated a bead that was indestructible from 1/8" plate. after it was all said and done, the truck was 7000 pounds plus. 3.91 gears and 33" tires.
the thing had a real healthy 318, but the gas mileage was only 4-5mpg. eek
grabbed a 440 out of a chrysler wagon. stabbed in an rv cam, hp manifolds from a super bee, and a thermo quad from ??????
instantly went to almost 15mpg ! plus, it ran SO much BETTER !
didn't need to constantly keep the right foot glued to the floor.
in this instance, bigger was DEFINITELY better ! boogie up
beer

I'm predicting these motors are going to have a very short life & will be very problem prone.

I tend to think the same way.
"If it sounds too good to be true....."
I hope they prove me wrong.

Probably a race to the bottom between the Hurricane 6 and the Eco Diesel motors. hammer

a very expensive transmission is probably on the way to fix that.

It'll have lots of speeds and that will make it super impressive or may even be a CVT, everyone's favorite!

I,.......fail to understand what the issue is here?

Wait: the issue appears to be CarScoops "click bait". smirk Sour grapes? Ram never gave them a Fuel Card and a loaded Half-Ton to drive for free for 6 months? pity



Turbo 1 and Turbo 2 are 60 and 110 lb-ft of torque MORE than the 5.7. For starters, does anyone have any idea what an additional 60, let alone 110 torque feels like in the seat? And, at LESS rpm?

They are comparing their 2024 numbers with 5.7 E-Torque. NOT apples to apples. Turbo 1 and Turbo 2 do not have a 48 volt generator and battery on them.

Look at the '24 Classic WITHOUT E-Torque for a fair comparison. Turbo 2 and Turbo 1 are a 1 and 4mpg improvement, which is significant! See attached.

I see NO downsides to the Hurricane engines: Better fuel mileage, AND more power at an rpm you can use. What is the problem here? shruggy

As far as being a little more complicated: all of Our hands are tied on this, get over it. The 5.7 has it's own history of miserable problems both computer and mechanical. Not a popular opinion, but an inline six is bullet-proof. At least you'll be able to change a cooked turbo out on one of these in an afternoon instead of tearing a 5.7 half apart to do lifters or a cam.

A lot of People thought the 5.9 Cummins was a pissy little joke compared to the Mighty Detroit 6.2 and 6.5 Blunder Motors, and Internationals' 6.9 and 7.3 How did that work out for Chrysler Corp? I guess Cummins was so bad Ford sold their Stock position in them. wink

Lastly, Premium Fuel: NOT an issue. Even the article says "Ram recommends the use of premium fuel to achieve those power figures, but regular gas will get those miles per gallon". I've run 2, high compression 3.5 Nissans, since new, and a combined mileage of 370,000. They both have giant stickers inside the fuel cap "USE PREMIUM FUEL ONLY". 99% of those miles were on Regular. The 1% I tried Premium there was absolutely ZERO difference in mileage and power. And they have yet to "blow up".

You have other problems if you need that extra 8hp you might get with Premium.

My thoughts are that a motor like this with twin turbos, will not be beefed enough to withstand the power output. They will tear themselves apart. Watch......
