I work for Cummins and seeing the tech they’re coming out with behind the scenes is mind blowing. Excited for what’s coming out!

We have 7 15L Cummins running on natgas here in the oil field. All have over 50,000hrs on them trouble free.

Gasoline. The best delete kit made. I literally specifically ordered my Duallie 3500 with a Hemi to avoid the issues of Diesel Regulations.

Cummins already makes natural gas engines for their natural gas generators that we use offshore and on hospitals in South Louisiana and also for water pump stations some big 6.7 L engines that work off natural gas. Or to run on diesel, the engine designed to run on natural gas or diesel whatever fuel you have.

The look on Nathan's Face @0:17 when Andre makes a Sir Mix Alot reference, is priceless, lol.

One thing I think is that if they give up Cummins in heavy duty truck while the other manufacturers still have their diesels they will loose. Ram Trucks are very nice trucks but Cummins is a big part of what people like about them. Replacing the Hemi with a Cummins gas engine might work as long as it performs but if they give up Cummins diesel for some in house motor I think that would be a huge mistake. Cummins has a loyal following and I think people will walk away without it.

Kubota did this because they already had diesel blocks, doesn't work the other way around because diesel blocks are stronger than gas blocks. Could make a VERY long lasting gas enginge

Good to see some ICE innovation in the face of the EV onslaught.

this will be the next "12 valve" as far as reliability and cost of ownership. I have been saying this for years, someone needs to build an industrial straight 6 gas turbo commercial hybrid platform. they will eventually get a ton of torque out of this thing.

Well if they got a crate engine solution and you can put it in an existing Ram because you want to get rid of the death filters and still have the ability to pull a trailer or haul a load that would be awesome and the possibility you could retrofit this to an older truck and have a stick shift behind it

I think it's a great idea for Ram to use these. Heck, they don't have to change any tooling, just built the chassis for the existing diesel and the gas version of this will bolt right up.

The gas Cummins, especially with numbers like you mention, would absolutely entice me to look at new trucks. I think it could wipe the floor with Fords 7.3 v8.

International used to build a huge I6 gasoline engine. The biggest one was 501 ci. But they also had 401,406,450.

So will the gasoline 6.7L inline 6 cylinder be turbocharged? A 6.7L turbo inline 6 gas engine would actually be pretty cool.

YES, this interests me very much. In fact the concept and application of multi-fuel diesel/inline engines has been used by US Army 2.5 and 5 ton military trucks since the 1960’s. This has a military component in it as well!!!!

Here's hoping we actually see this show up in HD trucks preferably in both gas and diesel versions, but if nothing else, in a gas version!

Absolutely interested in all the power plants that Cummins is making, and hopefully ram stays with Cummins

Multi fuel engines have been around for industrial and military since the the 1930's

Imaging this with a 10 speed Eaton

Great news from Cummins.

We have buses with the 6.7 that run in CNG. Super quiet engines.

Really nice to see more Internal combustion options for real world needs. especially working & commercial duty trucks.... Plus... being that it's using the traditional Diesel block.... which is designed for high cylinder pressures of diesel combustion/Turbo..... This would make this a Very Robust candidate for performance upgrades.... this might be a MONSTER if done right. looking forward to more details... Imagine a Ram 5500 with a Cummins Gas? sweet.

Cummins is gonna do this. I spoke with a sales rep years ago

In the 90s there was available a natural gas and diesel mixed fuel aftermarket kit for large trucks and later for smaller diesel vehicles. These used about 25% methane and 75% diesel. The improvement in noise, emissions, mpg, and smoothness was incredible. It was also complicated. But it might have been better than DPF measures.

Wow I thought this was an April fools gag, but it's on their site. Ha.

More Nathan, he is the best. I want to see him in every video

This is old news. Interesting, but even with an alumimum head, the 6.7 bottom end is still extremely heavy.

Old School. Been doing it since 1981. In a BIG Truck. And in the Oil Field For Many many Years. We Ran on Propane over the Road. The B 5.9 in the Oil Field on Nature Gas. 220 Cummins on propane was the first one we did then a 270. Ford HIE off a Volkswagen distb. Gear 10.5 comp. Imco carb. It’s about time they bring it to market.

According to rumors in Auburn Hills, a second engine is planned for these trucks. It, too, would be an inline six-cylinder, but engineered specifically for truck engines. The new engine is rumored to be larger-3.7 liters-and to have a more traditional design, other than an odd 30° tilt. A source within Engineering told us that it was tilted over to make room for accessories on the side so that it could fit into smaller engine bays; and to provide space for a better air path, increasing its efficiency. ...

The M35A2 DUCE 1/2 engine was also one of the first multi-fuel platforms able to run on diesel, Kerosene, Marine Oil, And gasoline. Powered by an LDT 465 in-line 6 cylinder turbocharged multi-fuel engine.

Very interesting and great new technology!

I had a 250 straight six in a 74 C20 that I preferred over 305 V8's. Same thing with 300 straight six Ford's, I preferred the 300 inline six over 302 V8's in trucks. They don't lug as bad as more powerful V8's. There is a legitimate reason why the inline six is the preferred platform for industrial diesel engines. My 74 C10 was used to haul scrap metal here in hilly western Pennsylvania. It wasn't worth taking a load in if it was under 2,000 pounds and she kept up with traffic just fine even on hills. I had an 86 F250 with the 300 six that was a rack truck that spent its life overloaded with ladders and scaffolding. The same deal, she kept up with traffic without giving any thought to it. Both happened to be manual transmission equipped, the 74 C20 was a column shift 3 speed and the 86 F250 was a 4 speed. Both had great fuel economy and neither had overdrive. With OD I suspect either would rival the fuel economy of any modern 3 liter v6 powered SUV or truck.

I imagine that Ram will probably offer the Hurricane I6 as a base engine with the upgrade to the 6.7 Cummins gasser or diesel. The diesel will probably remain as the highest priced and highest performing engine while the gasser 6.7 will be a mid tier offering. I think the gas powered Cummins will be cheaper because it doesn't require the emissions systems the diesel does, and diesel fuel injection is more complex versus gasoline fuel injection, even in direct injection applications.

I drive a 2014 school bus and it uses a natural gas Cummins

I thought we were expecting a derivative of the Godzilla Ford 7.3 or 6.8 with twin turbos to work in this class but with regular petrol. It sure would be cool to see these options in the Heavy Duty space.

Nice.... I could see the possibility of the 1 block for 3 different engines (if you can call it that) would make manufacturing more effective both in process and in cost. Great concept

I remember when I was younger, all the UPS step vans used the Ford 300 inline 6. Makes sense to bring back that engine architecture. Less moving parts, better reliability, and since it's gasoline powered, there's more available fueling for it.

The model T used a multi fuel engine. A look back on big truck engines I have a 1948 Brockway with a Continental R6572 gas engine (inline 6 572 CID) Continental built the RD6572 which was the diesel version just a different head.

I’d love to see this power train open the door for some gasoline powered Super C RV’s. Something that can tow better than the Godzilla but not break the bank like a Diesel.

I saw one of the natural gas semi trucks on Texas Interstate operated by UPS a couple of weeks ago.

The cowboy hat looks good on Andre. As for Nathan's cap: Taxi! 🚕😁

YES ! I am all for a gas 6.7L as long as they can keep the EGR off of the motor ! Also having it available as a crate motor option for hot rod builds 👏🏻

We have a few school busses with Cummins V8 CNG/Propane..they have done very good...

I have a 2019 Ram 2500 with 6.7 Cummins and would make the move in 2025 to a 6.7 Cummins gas if it came out. I think it will happen just unsure of timeline. Time will tell! Thanks👍

My '08 Jayco RV on the E450 chassis has a Cummins gas engine in it. It's the generator, but... 😉🤣

Was waiting for something like this a long time! Nice to see some major changes and trying to get away from the DEF crap somehow.

The reason it says no after treatment or DEF is because it is the screen highlighting the gas version.

This approach makes sense in a number of ways, I do expect Ram to offer this relatively soon!

This would be the only reason I would look at a Ram 2500. I was all in on another brand and there gas engine. I will wait and see where this goes. Straight 6's have been around a very long time and proven how good they are.

Cummins has been working on a CNG/Hydrogen version of the X15 for along time. They already have a Head conversion for the X15 and ISB 6.7

Ford could always dust off the schematics for the ford 300 and just improve the head and maybe add a turbo changing nothing with the bottom end and be bulletproof

In my line of business, we run the ISX15 natural gas engine, which is the same as their diesel engine, but the head just has spart plugs, and everything else is almost the same.

My wife love her Ram 2500 4wd with that beastly 6.7L. As long as the gas engine has a VGT turbo, it will be accepted. The ZF 8-speed powerline transmission should be a plus. The Jeep JLU performs better than the JKU because of the extra lower gears with the 8-speed transmission.

Would be crazy for the racing scene. Could run some wild boost numbers with e85+/race fuel

I’ve been waiting for this to come out since I heard about it a while back.

They do have parts in common, but Stellantis has a deal with Cummins to have a separate motor for the Rams. The B6.7 Diesel is found in the Freightliner M2-106 and International Medium duty and ICCEs so it will most likely be in thosr

There are transit busses running CNG manufactured by Nova Bus. They are Cummins manufactured diesel based power plants. Very emissions clean, ISL 8.9 L .

Cummins has been using natural gas 5.9L engines in generators for a while now. There is even natural gas DD series 60s in generators too.

In the 70s when I was in the air force Cummins already had multi fuel engines. So now there doing it in the electronic Era.

Great video guys! Unfortunately, with Stalantis being an Itaian company, I honestly don't see the Ram HDs lasting much longer. They don't care that much about the American market, and the truck doesn't sell as well as the the other two. This is the start of the downhill of Ram.

Bring it on now

Chevy did this in the late 70’s and early 80’s. They took an Oldsmobile v8. They took the olds 350 changed pistons and put on diesel heads and intake. My dad had one in an 81 caprice. When it finally gave out. We swapped the heads out for gas heads and 2 barrel intake and ran the heck out of it for several years.

Brings back nightmares from the days when GM and others tried converting gas engines to diesel engines! We don’t ever want to go back to those days!!

I've had 12 BMWs built and tuned like a diesel but with gas e85 fuel. low 4500rpm, small turbo, same afr as a diesel would. works fantastic. cheap corn fuel but 30mpg in a 6000lb x5 that tows with zero issues and makes diesel low end torque an new normal diesel top end. I'm really surprised it's taken this long for anyone to do

Very smart idea

i love big trucks, i cannot lie lol

325hp and 660lb-ft torque is incredible. Those are 05-07 diesel engine numbers and those trucks tended to pull heavy loads just fine.

If you know anything about older military trucks, White Motor Company built the multifuel engines for the M35A1 trucks. Instead of complex electronics, the injection pump system measured the viscosity of the fuel to cause the distributor injection pump to deliver the proper amounts to individual mechanical fuel injectors. This is a more complex way to do some of the same things using a common rail fuel system, or did they go back to individual fuel injector pressure lines from the high pressure pump source? Cummins has already tried extremely high pressure common rail fuel feed to the injectors. Any screamer Detroit 2 stroke is a common rail fuel source engine, any 855 Cummins and brethren. A new version of old with new engineer trying and money.

The computer's prompt "You're a manager'? 😂

That 5.0L Cummins V-8 was super reliable. As a boat anchor. Hopefully this is better.

Heck yeah, I'd be interested in such an inline six for the Ram HD. What other reasonable alternatives are there? I don't think I'd trust the new Hurricane six for such duty, and if it's based off of the Cummins 6.7 diesel block, it should be more than stout enough for HD pickup and fleet duty too. This could easily grab Ram some market share!

Based on current trends the only thing I'm certain of is stellantis will probably do the wrong thing.

I thought this was announced that they were working on this a couple years ago. In fact I think I heard the news from TFL

It's something they've been doing already for years. It's expanding to more fuels now, but the diesel and CNG versions of their mid range road going stuff has been sharing a block for years, among other components. I'm interested to see how many other components the new versions share across platforms. The natural gas versions in the bus fleet locally seem to be the most cost efficient, and least maintenance intensive option. With minimal aftertreatment required, they are very simple. But, they run HOT. There was/is a massive recall for the early models that melted the pistons since they ran significantly lighter than the diesel. Turbos are vacuum controlled wastegate systems as opposed to VGTs. I personally don't like the lack of power, but they work well overall.

Makes sense, but will it work in the current power wagon?

I would most certainly buy one of these!

This engine would be crazy expensive for a gas engine compared to the hurricane. I can see this as a replacement for the diesel but will someone pay 10k for an upgraded gas engine.

You put the gas version in a 2500 and you would convert my fleet from GM to Ram overnight. That 6.7 Cummins gasser with a ZF 8 speed IS A PERFECT recipe.

HAPPY EASTER! Glad you put videos out on Mondays so i can focus on CHURCH and FAMILY on Sundays.

When I started working in the oil fields, I was surprised to find out that Cummins made a massive natural gas engine to power the gas compressors.

Ram should have an option to bolt on an Eaton Fuller manual transmission to the Cummins engine

Come to Rocky Mount, North Carolina and see them put together NOW 👍 4/10/24

It will be nice to have a cummins that can be idled without the anxiety of wet stacking slowly leading to lifter failure. Let's just hope it doesn't have some hilarious oversight like the grid heater bolt coming loose and grenading the engine.

i am very interested in such an engine. Please continue research.

So here’s the Ram thing: currently, the Power Wagon isn’t optioned with a diesel because (according to Ram) the larger engine interferes with the sway bar disconnect and the winch. If the 6.7 Cummins moves into the Ram lineup, it either means that the PW gets redesigned to accept the bigger engine, or it goes away entirely.

That would be awesome in a heavy duty truck for folks who don’t need a diesel!

I think it would be a genius move and a very cost effective way to have multiple engine options for Ram. The manufacturing cost would be streamlined like crazy

I’ve always wondered the kind of life expectancy you could get out of a gasoline engine if it was way overbuilt like the typical diesel engine. 500k would likely be no problem. Probably could go well beyond that with good maintenance. Big straight 6 gas engines are awesome, better than V8s. With a turbo it’ll be a monster. This would be awesome in a HD ram. No DPF, DOC or SCR. 325hp 660lb ft is more than enough for what most do with a pickup truck. Although I do love the 850lb ft of torque with my 6.7.

Sounds good and cool at first but then comes the price. Im already priced out of the market with the existing trucks. I'll enjoy and admire from a far. Doubt I'll be able to purchase one if and when they put them in 2500s. Thanks for the info!

Seems like a great idea keeping a lot the same would definitely keep costs down

I've got an F-350 dualie with a diesel, it runs great but it's not a Cummins. I bought it just because it was pre-DEF. I'm just learning what that is, used to work on newspaper trucks back in the eighties, wish I'd realized then what they were going to do now.

Nathan, that would be awesome. 6.7 gas and 6.7 diesel options. All problems solved.

looks amazing. Slap some turbos on it

I've seen this coming for years. Diesel aftertreatment systems such as SCR, DPF, and EGR has been increasing initial purchase price and operating cost to the point where a durable gasoline engine could be overall cost-competitive with diesel. If their engine runs on regular, which currently is at $3.57 in my hometown, it would be cheaper than diesel, which is at $3.96. Without the aftertreatment systems and HPCR fuel system, initial cost should be a lot less than the diesel version of the same engine. If they expand the engine's capability to run on ethanol blends, the power and torque would go even higher, and fuel cost could be even less. E85 in my area costs $3.19 now, and running a blend of 50% E85 / 50% regular would bring fuel down to $3.38. Cummins has a long history with spark-ignition engines. They have run a subsidiary called Cummins Natural Gas Engines in Clovis, NM since the 1960's. And I worked on a natural gas C8.3 at Cummins in 1994-5. It used the same block and head castings as the diesel, but the head had spark plug machining where the injector used to be. Dished pistons at 10:1 compression ratio replaced the diesel pistons at 16.8:1. Doing production qualification tests on that engine, I accumulated 6000 hours of testing in about 18 months, and they never failed to perform. If Cummins engineers an aluminum head for the gasoline and natural gas versions, it would save ~200 pounds on the engine. Could be good. I would like to see the HP of the 6.7 gas engine get to 350 HP. The torque is good at 660 lb*ft.

Make it happen !!💯💯

Nice to have the option to switch fuel at rebuild time. Especially with turbulent fuel prices. Swich again if things change up

there is at least one ram with a 6.7 gas cummins, there is a video on youtube that is at a cummins event and there is a 2018 Ram with the engine as well as some 3 and 5ton trucks.

I would jump at the opportunity to get that 6.7l gasoline engine.

I would 100% take a long look at that.

What I really want to know is if I could swap out the 68rfe for the new ZF 8 speed in my 2017 Ram Cummins....??
