- I Review the 6.7L Cummins Gasoline Octane Engine rumoured to be going into the Ram 2500 HD pick up trucks and replacing the longstanding 6.4L Hemi engine . I discuss 5 reasons why this new Cummins Gas engine would be a great replacement in the Ram 2500 trucks. starting with the massive torque figure of 660 lb-ft of torque.

Well I was very excited Dive into the new 6.7L cummins Gas engine apart of their new HELM engine project allowing for the same engine platform to run multiple fuels with the hope of reducing the carbon footprint using low carbon emitting fuel and well the first engine of this project is the 6.7L Gasoline running cummins engine.
just so happens that Ram is probably looking for a new engine in their HD trucks to replace the 6.4L hemi V8 and well the timelines line up very well so there is a large speculation that the 6.7L cummins gas engine could find its way in the Ram trucks.
this cummins gas engine is putting out 325HP and 660 lb-ft of torque which is way more then the current hemi v8 offered in these HD trucks and much more then the compotition like the 7.3L godzilla V8 in the ford F250 superduties.
and that is the first reason - the torque generation
the second reason why I like these engines is the strenght they will most like have. being built on the 6.7L diesel backbone and sharing most components this gas engine will be a complete stronghold.
the third thing I like the the reliability. again being built on the 6.7L platform from the diesel engine. these gas engine should be just as reliable and well they are also coming with no emission systems which could make them even more reliable.
the fourth thing I like is the Cummins/Ram relationship developed over the last 30+ years so ideally this gas engine will be very easy to sort out between the two companies.
lastly is that this GAS cummins engine would most likely perfectly bolt up to the new ZF 8 speed powerline transmission which could be an absolute killer combination.

If you listen to the acolytes of carbon emissions reduction, they will continue to crank up the regs like a python until we are all riding bicycles. Ultimately YOU are the carbon they want to reduce....
commuting by bike sounds pretty based ngl
Reducing carbon meanwhile the lithium mines off gas way worse on top of leveling water tables eco systems etc
There is actually no reason at all to reduce carbon emissions. Let’s look at this like we aren’t insane liberals pretending Hunter isn’t a crack head. Our planet which has been here for about a billion years longer then humans is actually smarter then we are. The more animals (humans) or any other animal on the planet, the more food the planet has to produce to support said animals so the planet knowing this heats up to create a longer growing season for the herbivores and in turn more food for the carnivores. So the planet heating up isn’t a bad thing at all. Now I know I know everyone says but but but the oceans are gonna rise and flood the coast lines. Negative not gonna happen the hotter the planet gets the faster the water on the planet evaporates and the more it rains to produce more plant matter if every gram of snow on the planet all melted tomorrow because the planet was so hot it would just evaporate and fall back down as rain somewhere and more then likely our deserts and Sahara’s would turn back into forests and grasslands for the herbivores. Every single liberal green idiot needs a real lesson in how our plant works.
Ding ding ding.
im down for that, ID even ride a damn pennyfarthing. (for style and brass huevos points.)
Because it makes sense is why stellantis probably won’t do it
I really want to see this gaser live. Inline 6 with turbos, simple and just a tad of tech has to be a hit.
Agreed
I don’t think it’ll be that bad it’s a good idea everything below the head gasket is going to be the same with I’m sure a little different pistons of course but a new head and ignition system and the elimination of a dpf system that’s a trade I’d be willing to make especially if Cummins is doing it I think that would put ram hd trucks ahead of the market a ways
@@nashdavis4607 get ready for the GPF (gas particulate filter) for 2025.
@@user-yd1dx5qs4j is it in the works? The damn epa needs to back off lol
@@nashdavis4607 yes. It's in the works. So I am hearing we will be seeing GPF in 2025 or 2026 vehicles. Get ready bud.
Sounds great! The biggest problem right now is that not many can afford the new trucks now.
and I can't see this cummins gas engine being cheap!
@TheGettyAdventures that's a good point. Basically a gasified 6.7 so yeah probably expensive
That’s by design. These “democrats” are pushing for a socialist/communist one world order where the majority are dirt poor and only the filthy rich own vehicles, property and eat real foods
As a Dodge/RAM truck fan all my 63 years and being a mechanic for 45 years I think it would be foolish if they don't use this engine in the HD RAM trucks.
I'm not sure why they haven't done it before, as the 5.9 was available in diesel, gas and natural gas and or propane.
I couldn't imagine being a mechanic and still somehow being so ignorant that I'd continue to buy dodge vehicles. The amount of short cuts and cost cutting I find on these trucks is disgusting and that's speaking from experience on our half ton and 1 ton service trucks. And from experience doing a resto on a 90 ramcharger. Junk brand selling you a half ass product designed to fail, at least they made them simple to fix for the most part.
Heaviest HD gas engine for sure. It might be the next great engine for the segment.
I think only the moving parts matter for weight in this application since the truck is already heavy. Still won't be good for mpg.
Well done video. I like the Cummins gas motor option in the heavy duty truck applications. Should help bridge the gap with low end torque between diesel and gas engines, especially while towing. Cummins is the perfect company to introduce these new generations of gas engines based on their previous reputation of power and reliability across the board.
The Cummins gas engine might just be the ticket. Imagine everything you love about your current Cummins including the awesome fuel economy, now imagine the fuel is 50 cents cheaper and there’s no def. Win win win.
I'm not sure about the rest of the country, but here in southern Nevada diesel is finally about 50 cents less than regular unleaded. NOW the world is no longer upside down like its been for several years in this aspect. Now, cheaper fuel, better MPG, better reliability and longevity in a diesel, so I'll keep my 2006 pretty EGR system 24 Valve 5.9 Cummins. Never had an issue with this engine.
I’m sure it’s going to require premium fuel to meet octane requirements. Which is more than diesel in Texas at the moment.
@@dingo3190 Not if its DI. Direct Injection injects fuel at the time the fuel is needed, minimizes the pre-detonation issue. Almost diesel like.
Yeah but that mpg is gonna be down in 5s 😂
Diesel was always $0.50 cheaper then gasoline until the year 2000. Consequently, gasoline was $1.46 in 2000. Now in 2014 diesel prices went to being $0.50 cheaper then gasoline that year but, no one ever said anything or ask why. Like it never happened.
arge bore / long stroke straight 6'shave always been real workhorses, remember theM Ford 300 cubic inch straight 6 pickup it was a good tow vehicle.
Them Chevy and dodge had straight 6s that where work horses not just trucks but big sedans and station wagons
Wrong, I've owned several of them including the fuel injected models and they are absolute dogs compared to a 302/5.0. My current daily driver is a 95 Econoline with a 4.9 l and even after converting it to a side draft Delorto 2v carburetor it still gets 10 to 11 Mi per gallon and is a total dog, causing me to hand shift it to keep up with traffic
@@woodardkingsbury1648the Chevy 292 was way much more of a Workhorse than the Ford 300 and I have owned both
I think hotrodders and tuners are also going to love an overbuilt gas engine.
big tunes incoming lol
I can imagine the sound living in an emissions state of a gas 6.7 cummins with no muffler. I think I can live with the loss of the hemi in the 1500 if I can hear that cummins sound legally. And the reliability of a deleted 6.7 and some because id assume that a failing gas injector cant melt a piston, let alone a diesel piston. Pray they actually do this. Id go as far to say that if done, the gas 6.7 would lower current pre emission diesel prices back to normal.
The Duke says, who says it's going to be overbuilt? Diesel engines are overbuilt by design because of the high compression they create. You don't need an over designed overbuilt block for a gas motor.
For example the 6.4 hemi is not built like a diesel engine.
That includes Chevy and Ford.
Stellantis is going to want them to make it as light as possible.
What did I teach you?
@@bigedmayrait would be more expensive to design and build two different engine blocks, did you not watch the video at all. He literally said they plan to use the engine base engine design and essentially only change the head based on what fuel the engine will be using. Much cheaper to design and produce 1 engine with interchangeable parts than design 2 or 3 different engines
Will be holding onto my 2006 5.9 G56 truck till I die.
Good, keep it it will serve you well
From my personal experience with hd diesels, paccar cummins perkins detroit CAT, and learning from old school mechanics. I personally believe that the gas inline 6 could be a new power base do to displacement and revamped designs, coming a long way from prior inline gassers, with alot of upgrades to the older style engines they could get pretty rowdy. In short I'm excited🤘
I like this gas engine with a turbo. The horsepower and torque numbers sound good and is prolly a lot more cost effective than a diesel. I like my diesel but this would be a good alternative
You know, I love the idea of this. Especially the “overbuilt” aspect of this gasoline engine. However, I can’t help be skeptical wondering if Stellantis will do this. I have no inside information, but it sure seems to me it’s going to be one heavy, and expensive engine. I can understand the efficiencies in manufacturing, but I’m not sure it will be enough to prevent a large increase in MSRP.
As far as performance, it’s going to have to be a low-revving grunt monster. I can’t see this reciprocating mass revving much. Probably will be fine (probably great) in a big truck. I’m cautiously excited.
The expensive parts of the diesel Cummins are, the ultra high pressure fuel pump, the Ultra high pressure injectors, the $8,000.00-ish to replace exhaust, take this away and you get a much simpler, much lower cost, much lower maintenance engine. The problem with all the current gas turbo truck engines is super high cylinder pressures, heat etc from squeezing tons of horsepower out of half this engine size.
I hope you’re right. I’m rooting for this potential option. We’ll see.
Good idea that has merit. Add a7 speed manual and I will be first in line.
Large I6’s tend to have exactly the torque curve you’re talking about. Max torque well below 2500 rpms. The old Ford 300s acted just like that. A bigger, more modern HD I6 just makes sense. V8s are great, but an inline just makes more sense for a truck.
Great info 👍👍
Tuners are gonna have a field day with these.
A 6.7 turbo gas 8spd would be interesting. Class leader most likely.
Lol
It's not going to be turbo
@@bigmurph1447it is turbo charged look it up the info is all over the place
@bigmurph1447 yes it would be Turbo. As Cummins is marketing that 6.7 gas with a Turbo. Since it would be interchangeable with the head, to run on different fuel.
@bigmurph1447 Yes, it is single turbocharged. There's already published information on this engine, Google cummins B6.7 Octane engine and see for yourself. This engine looks very promising, having no aftertreatment, no EGR, just turbo GDI with a three-way engine mounted catalyst. I really hope Stellantist uses this engine
Great video mate.👍
Incredible show sir 👏
Well thank you sir!
Awesome idea- love inline motors-
Maybe Ram might even update their ancient HD platform at the same time….wayyyyy overdue
The initial concept of the 8.0 V10
Definitely interested in that gas Cummins and what is in the future for Cummins projects.
Great video!
I've always like inline gas motors starting from the 292
I had a 250 in a 67 Camaro, plenty of power and got 30mpg.
There were big Hi CI Gas engines back in the day IH had some. GMC had some V6 engines. Cummins and Cat has had industrial NG engines for years!
GMC also made the v6s in a V12 version. Cummins offered the 5.9 in gas, diesel, natural gas and or propane
They did this because aftertreatment woes on the mid duty diesel trucks are causing too many problems. The 6.7 gasser is going into class 5 trucks only
My bet is that the base engine in the 2500 becomes the hurricane (with the existing transmission) since it already has more torque at lower RPM then the 6.4, but it won’t be good for high work duty cycles so they offer the 6.7 gasser as an upgrade with the new HD transmission for a hefty price and significant extra weight but boosting towing numbers; possibly better payload too if they offer stiffer springs with this package to help achieve towing tongue weight
As powerful as they are, a 3.0L gas engine will never be in an HD truck.
Once it’s established and with some track record, I’d get in line to replace my 6.7 HO 3500.
My brother ran a 6 cylinder with a 4 speed manual and it was a great truck with a 9 ft bed and you could not kill that 300 ford in line six it was a bad ass with twin turbo it has to be a beast !!
I am a Chevy man and had a 300 six 77 ford 3/4 ton that had a trillion miles on it from service as highways truck, it never gave up, one of the best engines ever. I think any inline 6 is the best
I'm glad you put a turbo on it, because it is not impressive otherwise. Nowhere near the torque of a 302, whether it is fuel injected or carbureted
@@MrThewhip333definitely a very durable engine that's for sure, but as for horsepower Orr torque not so good
I would be interested in seeing it
Two spark plugs per cylinder is a great ideal and I flew small planes and it’s amazing the difference between one spark plug per hole and two plugs per hole and it makes a big difference!!
Aircraft have two plugs for redundancy not for performance . Thats why the mags are selectable incase you drop a mag you can switch over to a secondary mag
Yeah definitely makes a difference. Doring primary training I was doing touch and go's and I eas thinking this Cherokee is a dog today. It wasn't a hot day and the barometric pressure was pretty good that day. I looked down and noticed one mag was off. Switched it back on and it was back to it's old self
@@apollorobb You are not a pilot, are you?
You're dealing with magnetos. We haven't seen those in passenger cars in 50 years. 😂
A new good coil on plug system is capable of 60000 volts, so it's already like running 2-3 magneto driven plugs.
Then you have combustion chamber shape, and piston squish. Both of which wildly change the spark required to reliably ignite the charge.
Basically, relating airplanes to cars is dumb, as airplanes are old tech and haven't had to keep up with EPA to make them efficient.
@@leftyeh6495 With 2 plugs you are also having the flame front start from two different locations. It's not all about higher voltage and a wide gap. If you had a engine indicator graph, the pressure-volume curve is quite a bit different
That's a great idea! As you said, the strength of the bottom end, and the rest of it is perfect. It would probably require very little re-tuning. Another hole in the head, a sensor or 2 on the crank and re-profile the cam timing. Even with the turbo, it should bring reliability up and equal to the iron block LS. I have that in my GM Silverado and it's a great engine. No reason the 6.7 would not be a very high mile engine also. Even if they used the Aisin trans, like the diesel option. Thanks!! --gary
Fuel efficiency good towing characteristics, good midrange torque output, good parts availability, user serviceability. Longevity being high likely. Definitely a contender if offered in power wagon trim. Or just general work truck trim.
My 2021 Ram 3500 6.4 Hemi workes great for me.. my rv is only 8k loaded my truck will pull 14.5k lbs, that puts me in the sweet spot...👍🇺🇸🙏
Ewww V8
Any electronic issues.
Have yet to be impressed by a 6.4 hemi 🤷🏼♂️🤷🏼♂️
@@Austin-jd4mceeewwwww electric vehicle loving liberal
Whata your mpg on that load?
Tentatively I’m interested to trade in my 22’ Tundra. As long the reviews are solid and dealers don’t go greeting and do mark ups.
YES!!!! Gasoline simplicity and something the competitors don't have big gas engine turbo charged. I think these might sell better than the Diesels
The VW VR6 was designed as a diesel but was resleeved for gasoline. A 2.5 ltr one cylinder head turbo v6 good for 750hp daily driving.
With an aluminum block will make a huge difference for weight savings. JS
I love the thought of this.....only thing I wonder about is the cost. Considering it shares a bunch of components fromt the diesel, whats the price difference going to be compared to a diesel. People would probably stick with a diesel is its only 3k difference. My 7.3 gas was almost 10k less. It needs to be really cheap or it may not gain traction in the hd truck market.
I think it would be a great idea., all I hear about with many new engines from all companies are timing chain and cam phaser issues. These high dollar vehicles with expensive repairs before you can even pay the vehicle off. Put the Cummins in with a 100K warranty and it should sell well.
Will I be rushing out to trade in my all paid for bought new 2023 Ram 2500 HD 6.4 for this? No I’ll let the overzealous guinea pigs test it for me first on their dime ! 😂 My 6.4 does whatever I need it to do.
You bought a HD without a Diesel ?
Damn that sucks
@@billyzgoneape no it doesnt
@billyzgoneape it make sense for what he or she needed it for everyone doesn't need a Diesel
@billyzgoneape umm... you probably are completely unaware that diesel is quite a bit more expensive than gas. If you factor in price per mile, gas wins or equals out. Those 2500s have over 3k lbs of payload compared to 1,800 with a diesel. I have a megacab wit 4.10 rears. I live in an area thats flatter to my east and mountains to the west. I get 19mpg+ if i go east and 17.5 going west. If I am pulling horses, I get 12.2 everywhere. It doesn't seem to matter the direction. I don't drive like a jackass though. I have way over 1 million miles pulling oversized loads in a big truck. That 392 is plenty for 15k lbs. The raiting on my vin says 18,900. I don't think that's logical with any 2500. This 6.4 is fully forged. You probably didnt know that. Right down to the wrist pins. I have seen a guy with a fleet of 6, 6.4l 3500s that pull hot shots of 20k all the time. He's getting 350-450k .miles with zero issues. This cummins gasser is the same as the diesel with a different head. It probably will be better yet.
@@billyzgoneapeYa who wants more payload, no emissions or def, and to spend $10k less? A diesel makes less and less sense- these days it’s almost always going to cost more in the short and long term.
Should be a game changer, anyone remember the 300 Ford straight 6
Who knows that Ram has in store but it could be.
Personally I think they should stop taking things away from us like children and let us choose ex. 6.4 6.7 5.7 etc. why try and fix it/take it if it’s not broken! Grow up!!!
the more options the better in my opinion.
Is this the modern Hall-scott gasser? Hope tbe mileage is better.
I could totally see companies like fedex and ups using a Cummins gasser in their delivery trucks as opposed to the v8s and v10s they’re currently using
The problem with that transmission, based on those specs, it's rated max torque is 1000. The High Output Cummins is rated at 1075. Maybe for a standard output Cummins that is under 1000 torque. Interesting to see what happens next.
Being turbocharged I just wonder what the MPG would be compared to the 7.3 Ford. I know towing with my EcoBoost is not eco under boost.
I'm all for it though!
No engine is great on fuel when towing
Love the idea. Can’t help but think how much less pollution gear than a diesel. Should work pretty sweet.
A lot of people like to compare the price of gas engine HD trucks vs diesel HD trucks. I see a lot of people compare things like MPG and fuel prices as well as maintenance and upfront costs. What I don't see a lot of is the resale factor. I could absolutely get away with a gas engine, but I drive a diesel instead, and it's simply because of longevity and resale. When you factor in how a diesel holds its value, they're almost always a better financial decision in the end.
Imagine if Cummins did a Ford PowerBoost version of this engine. Possible 400+hp with 700lb-ft of torque plus the ability to add as an electrical generator. It would be a hell of a service truck.
Ram and Cummings should do it!
Well I for one am not a v6 fan with or without turbos. So I will be looking into these model's because I am a hemi fan to start with.
The better question is which EPA rating is the 320HP and 660ft lbs from, below 14k lbs GVWR or above 14k lbs? Due to differences in the EPA tests for those two cases, you get different power and torque ratings.
I'd be interested in a 6.7 Octane in a Ram 3500 with a ZF Powerline trans. My 2012 Ram 3500 with 6.7 is rated at 350 HP and 800 ftlbs.
Very interesting, does make sense.
@@TheGettyAdventures Here is a brief explanation of it: ruclips.net/video/TNRwwUIsG4Q/видео.htmlsi=c1xluxeUPLvefgnd&t=224
I would buy one today
With few bolt on part changes, like oil pan, intake and exhaust, Ram could tilt the block and call a Ram slant 6. Just a little old school.
If they do this it will be the next “12 valve” in terms of reliability and cost of ownership. Cant beat it especially if the do an industrial generator/ hybrid. Generator for use as an exhaust type brake.
It will certainly be a pretty stout gas engine.
Lack of emissions equipment alone might be the selling point, with that strong bottom end, seems like a win to me.
Torquee turbo gas 6.7 in a HD paired to a 8spd ZF? Yes please. Those power numbers are very mild for a turbo gas engine, read reliable. Compared to 3.5EB making over 100hp/140ft-lbs per liter, vs this cummins at 50hp/100ft-lbs per liter...so hopefully it should live a long time doing HD stuff. I drive a 18 dmax but would love if there was a reliable turbo gas option from ram
I'm sure you'll mention this in your 5 con's video, but unless Ram finally gives up their blind adherence to the 10k GVWR for the 2500's, switching to the gas Cummins could be the death nail for their gas HD truck line. One of the prime benefits of a current gas 2500 over a Diesel is the difference in curb weight thus higher payload.
If you've got a common block and a lot of similar componentry, yes you'll shave some weight by ditching the aftertreatment system, but that is gonna be one hefty beast. Far heavier than a gas HD buyer is going to be accustomed to.
I understand when you say "no emissions" what you mean, but consider you will still be looking at catalytic converter(s), EGR, EVAP, etc. I fully understand the advantages you refer to not having an exhaust filter SCR, DEF etc and not having those are huge but there are still emission control devices involved.
GPF is coming..
100% but the carbon output of a gas engine is a fraction of a diesel making EGR gas much much less destructive.
If there was a decent substitute for the outstanding exhaust brake on my 2016 Cummins, I'd honestly switch ASAP just to get out from under these emissions issues.
But will it still be a 20k option upgrade?
If the 6.7 Gas is going to make such strong torque numbers, especially at such a low RPM, it’s going to have to be boosted in some fashion. You can’t build that kind of cylinder pressure that low otherwise. Also, I don’t think the stroke or weight of the rotating assembly is what helps the engine make that kind of power so low down. The heftiness of the bottom end will definitely help with reliability though. If the 6.4 was designed to handle the forces as reliably, it could do the same thing with a smaller cam, smaller ports, a redesigned combustion chamber with DI, and a turbo.
Would buy one ! 👍🇺🇸
The 6.4 engines is a good engine. Great power
PLEASE MORE GASSERS amd diesels too
I suppose this goes along with the Hurricane I6. For smog reasons it may have been more cost effective to have an all new I6 than add new items to the 6.4 hemi. I never heard of a GDI hemi V8, and I do not know what would be needed to make one. Until GM made the Gen V LS, I figured it took a DOHC 4V engine to have a GDI engine.
A low revving I6 makes sense for long life. The Ford 300/4.9 was an overbuilt engine with a low redline. It only got cancelled to meet smog. The 1996 F150 was the last one, and it had all kinds of extra smog stuff. It led to the basic 1997 F150 getting the 4.2 V6.
Maybe they could fix the suspension on the 3/4 ton while they are at it.
I think I will keep my 02 80k miles fully built...and my fully DELETED 27MPG 600HP 1,500 ft lb 18 CUMMINS....and diesel is .50 cents a gallon cheaper, almost always where I live. But great video and good options for future buyers
I do believe partly that the 5l was a fail and the 6.7 issues all stem from epa standards. I had a 12.7l Detroit from 2000. I put on am oversized turbo and turned it up around 525hp. I ran the piss out of it for about a million miles before I sold it. Still didn't use oil. Had an N14 from 1995, same thing. 410hp. I had another n14, it was a wierd hp, 485. No issues. My dad's last motor was a C15 from 2004. He had 650k miles and then went in and took the egr out and slapped on a big turbo, then had it turnned up to over 700hp to the ground. He ran it to 1.8 million miles like that. It was using a gallon of oil every 12k miles at the end. He did an in frame and he's around 2.5 million right now. Cat made him put all the crap back on to get the factory warrenty in the rebuild. When you're blowing 30k to rebuild a motor, you want the 250k mile warranty. They need to just leave these makers alone and let them build what sells. My dad still has a 2003 ram with the 5.7l he bought new in aug of 2002. Not a thing wrong with the mechanical aspect at all. The body is rusting.
When you said how long Ram has partnered with Cummins, that appears to date back to 1989 when the first Dodge/ Cummins truck came out on the market. Had Dodge not done that and if they had not come up with some other diesel engine source or made their own and would have had to have been a reliable hit with the market, Dodge "Ram" sure wouldn't have the presence they have today. I know a lot of guys that bought a Ram simply because of the Cummins engine, not because they were thrilled with the truck itself ( at least years back anyway )
You're 100% correct. Without Cummins, Dodge / Ram would be a small fraction of what they are today, or may not even exist at all.
I see a ProCharger in your 6.4 hemi future. Do it
Confused here?! The Cummings gas turbo engine sounds like a great idea, but I keep hearing about the hurricane engine which will it be?
So I’m assuming it will be turbocharged. Should be the same as the diesel except for the head and pistons right.
More or less what I'm thinking. obviously different fuelling set up. it should have a different turbo as well. but the rotating assembly looks and block look to be very similar.
The root problem of the current turbo gasoline engines is the strength of the engine platform. Ie: main, rod bearings, heads are made as light and small as possible to maximize profit and payload.
CAT has long had a natural gas version of their motors. Valve recession is a significant problem with those engines, but otherwise pretty reliable.
Cummins needs to pay attention to head and valve seat cooling in particular to avoid this issue.
I’ll be watching!
It’s hard to imagine a 464 ft/lb gasser (L8T) being in last place but yet here we are. It’s a good time to be forced to “settle” for the gas option.
I'm very interested in this if it has a zf8 speed, I wonder what the fuel economy will be??? Personally I won't buy a new diesel because of all the bull shit emissions, I'm still running my 07 5.9 and 96 f350 460....
I’d buy one for sure. 6.7 inline six with turbo charging? That would be perfect for my needs. I have a diesel but it’s getting up there in miles I’d trade it in on this
The one downside I see is that usually spec'n a truck going from gas to diesel is an additional cost of $6K-$10K. I think with these new gas Cummins the price for the gas/diesel may very well be the same and the price of the base truck price will just be higher. Granted the gas doesn't have a $8K exhaust system on the gas version I could be wrong.
Very interesting. Love my 6.7 3500 (2011 so no def😊). Amazing truck and motor. Could be a big winner for both RAM and C to have gas version. My negatives are: 1- Cost. C motors adds a big premium to HD trucks. No way the gas version can compete with Stellantis cost to build a 6.4 Hemi. 2- Untested bleeding edge. Risk to both Ram and C to go high production of first gasser. The could be devastating to both if this engine is a stinker. 3- Performance. High torque, yes, but will likely be quite slow by going with the diesel block and long stroke pistons. So RUclips will have fun showing off how Ford and GM walks over the C Rams ( except for towing, which is what counts). 4- Ram HD production very limited to what Cummins production volume of gas power plants. C volume of 6.7 Diesel was much less than half of the total Ram HD trucks. This new gas power plant would mean all Ram HD must have a C engine. 5- Weight. The 6.7 power plant is about 1100lbs. 6.4 is less than half. This could be a real issue for those that need high payload more than high towing capacity.
Anyways, I still think good on Cummins for coming up with modern solutions.
Agree with everything you said sir! going to be talking about this Tomorrow actually - well maybe tonight if I can get everything done!
Any plans to review the new Ford 6.8 gas?
That Cummins would be cool but seeing the numbers the hurricane high output is putting out I see that more likely in the 2500s
Torque is great but 325hp is pretty weak tbh. Having over 400hp just makes the truck drive better IMO. Thanks for the review
Would be cool to have a gasoline Cummins engine, but where would it fit? Would it be able to tow the same as a diesel engine? If it’s just going to tow the same as a 7.3, our company would rather stick to that since ford HD gas engines are pretty easy to work on and very reliable.
I think Ram would probably want it to sit above the 7.3L but obviously below the diesel engines. It is an interesting question because the gas engine are starting to really push into the diesel engines territory. the 7.3 I think can tow north of 18K when properly equipped so I can't blame anyone going with Fords Godzilla engine!
Heaviest HD gas engine for sure
Seems like the hurricane HO will most likely be the replacement for the 6.4 hemi in 2500/3500 Rams
Sounds good, probably will be very expensive to repair.
This combo could keep me in a Ram
From what info I have seen out the only difference between the gas and diesel 6.7 is from the head gasket up I am sure there will be slightly different pistons but they are claiming the rest is the same engine
I also think the piston will be different but ya it sounds like the vast majority will be the same.
Its too good to be true. It will get watered it down, they cant have anything lasting too long.
That would be pretty awesome to have low end torque like a diesel, but be able to rev like a gas engine! I think it would be a win fir both Cummins and Dodge!
Just from the numbers this will be a diesel like low RPM engine. High torque, low horsepower and long stroke dictates this will be a very low RPM engine. If you take a similar torque curve I would assume this isn't revving over 3200 RPM from the factory.
I'm waiting for that 6.7 gas engine to come out because I'm going to swap my 5.9 with it I'm also going to put a 6-speed manual behind it waiting for that crate engine to come out
I like the sounds of that!
RAM is a REAL man’s truck
lol...they all do about the same things.
I like the style of the ram’s I like the Cumming’s engine,even the gas motor is cool, my concern is the overall price of these trucks and trucks in general in the market.
stellantis seems like it’s circling the drain right now, Ram is laying off,
As much as I want a new truck these manufacturers have gotten extremely greedy and it’s just too much for a lot of people and that’s why I’ll be keeping my old truck running for as long as I can.
Banks is going to have a field day with this...
I get a stiffy thinking about this cummins gas with a 8 speed.
Will buyers pay 10-12k for a gas option?
Holy cow, 660 out of a 6.7 gas would be huge for Ram. That has me asking if the gas version has 4 valves per cylinder like the diesel. Also, what are the other internal differences compared to the diesel?
If Ram wants to gain market share on its HD trucks, it’s going to need to significantly improve payload, towing and it should discontinue the mega cab and bring the 1/2 ton crew cab body over to the HD trucks. I’d simplify the HD trucks offering a single cab, and crew cab. I’d the. Make sure they have the best body, frame and powertrain with an update scheduled for every 4 years and an “all new” truck every 8 years.
Currently the RAM HD is the old frame, pretty much the old cab with updated interior and front end.
Turbos for diesels and superchargers for gas engines, that’s my preference.
