It's Not Just Diesel Anymore: Cummins Built a GAS Engine We Want to See in the Next Ram HD!

( www.alltfl.com/) Check out our new spot to find ALL our content, from news to videos and our podcasts! Cummins built a new "fuel-agnostic" powertrain based around their B6.7 diesel engine, including a gasoline variant called the B6.7 Octane. Andre and Nathan go into more detail on this engine including the most obvious place we'd like to see it in action: Ram's Heavy Duty truck lineup!

The EPA is completely corrupt. I used to work in emissions and I watched as the Diesel just got destroyed by regulations. Everything go tso sophisticated it is an abomination. My belief is they EPA is in cahoots and wants to shut down the entire internal combustion prime mover industry. Electricity is a SECONDARY energy. That means you have to generate it somewhere else then put it to work remotely as in wires everywhere or batteries. It is so inefficient to do it that way. but people are just sitting and letting them take our freedom away from us. We need to take a stand somehow and shut the EPA right down and disassemble it.

Agree, The big challenge for a spark ignited engine is the ability to transfer heat into the jacket water. With direct injection, 3 way catalyst and a specific cylinder head this engine could be really successful. It takes more than just putting a spark plug into a diesel head and calling it a day.

[@ramcharger1978]

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.

[@derekbryant6137]

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

[@knightwing4]

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.

[@thevortex6754]

I think it just allows for more and better options. Because Cummins and Ram are so good, and like you said, Cummins has a loyal following, Ram and Cummins might do better with this head change tech. I love Cummins, I’d buy any engine they make, gas, math as, or diesel, great engines

[@gregkocher5352]

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.

[@KevinJames-yg9eu]

As an engineer at a truck manufacturer, I have more recent experience with Diesel engines that have aftermarket conversions to run on natural gas. On smaller engines, like a Cummins B, they entirely eliminate the Diesel fuel by installing spark plugs in place of the injectors and pumping natural gas into the intake manifold. On larger engines, like a Cummins X, they make dual-fuel system that uses a small amount of Diesel fuel as a pilot injection to light off the natural gas.

[@derricklowell]

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. ...

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.

It’s about time they bring it to market.

[@truracer20]

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.

[@ALMX5DP]

Inline engines do seem to be making a comeback, though obviously with turbochargers since people expect a modern level of power and torque.

[@dougzzzie738]

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.

[@roadsplorer]

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.

[@mddunlap03]

Why? The hurricane is a from scratch engine. New tooling new block new everything this is a 6.7 with a aluminum head and cast pistons. Hurricane will shit the crank out the block of it had to make 650+ftlbs at 2k rpm

[@DJ-ve5lr]

If not diesel, but same engine it would be interesting to see the price diff. I wonder how much of that 10k premium is caused by fines and diesel regs.

[@andyharman3022]

If they can keep the cost of the gasoline engine option to $4000 over base, I think it will sell well. The diesel option costs ~$10,000. The gas engine should be cheaper due to no DPF or SCR systems, and the fuel system will be cheaper as well.

[@Lloyd973]

This engine would not, in my opinion, be an option for large hd trucks. It’s fit would be better in the medium duty truck market, say in the freightliner M 200 series or any of the large box delivery vans. The natural gas option for these trucks would be a better fit. Hydrogen gas is a pipe dream for anything not mounted to a stationary platform. Just not enough heat energy in the gas to make it truly viable for anything else. Natural gas options have been around for years. They burn cleaner than gas and have fewer emissions problems and a very good maintenance cost per mile over the diesel. I don’t look to see this in any Ram pickups. Just don’t think there would be enough cost difference to make Ram dump their newly designed six cylinder engine.

[@wtbman]

@@DJ-ve5lr I would think a huge part of the $9k+ Ram charges for the Cummins is due to the SCR/DPF systems. That's like $6k to replace. The 6.4 Hemi to 6.7 gas Cummins would be more like $2-4k I would think.

[@patrickmoran8790]

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.

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.

[@JBansal]

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.

Excited to see this in a future Ram 2500 or 3500. The benefits of a gasoline engine not developing all that carbon soot blocking up the EGR, no DEF, able to drive teh car 5mins down the road to the shops without worrying about gettting a diesel up to operating temps to burn cleanly, there's so many positives. And that's before the aftermarket tuners even get hold of these motors! So much to like about this - and from an Australian perspective, it's like running a big Ford Barra engine that's going to be tuned. The diesel engineering of the bottom end will add an awesome ability to pull much bigger numbers out of these motors!

[@thomasniederberger2950]

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.

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.

[@jeffs2809]

Don't be too surprised if you see a GPF on that truck when/if it hits the market. Gasoline Particulate Filter. They've been on vehicles overseas for several years and are starting to show up on some in the USA. In particular the new Ford nautilus SUV. I expect them to be more common as the new EPA '27 rules get implemented.

[@truracer20]

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

[@brettegbert6985]

I would most certainly buy one of these!

[@saltysteel3996]

Toyota won't sell diesel engines in the US because regulations are too strict and unreasonable.

[@andrewhatton1606]

The liberal way

[@dcooper91g]

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

[@cfyves]

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

[@jasonwooden]

Would have been good to include the Hurricane Six in the discussion. Unsure if it could be beefy enough for a HD pickup, but it's the only current option if the 6.4 is going away.

[@MattChat56]

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.

[@Patrick-xd8jv]

The company I work for has been running thousands of cng otr trucks and package delivery vehicles for probably around 8 years. If you have any thoughts on owning one, you had better make darn sure you have a pumping station everywhere you plan to go. The range is very limited. They eat spark plugs like candy. They crack cylinder heads more frequently than they should. Power is not equal to diesel. I am glad that I still drive a diesel

[@AlienLivesMatter]

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

[@JREwing78]

The aftertreatment tech required to make diesels work is its Achilles' heel. Cummins is smart to push the CNG and gasoline options. The marketing play for the B6.7 Octane is that it's so overbuilt it will basically last forever. The question is whether they can make it efficient enough to overcome its extra weight compared to the V8s in the Ford and Chevy. An interesting alternative would be a turbo 4-cylinder version of the B6.7 Octane; it could boast superior efficiency and not have the weight penalty of the 6-cylinder.

[@GrizzlyDude]

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

[@khakiswag]

Didn’t GM try this in the 80’s and had disastrous results?

[@Journey_of_Abundance]

Tech has improved a lot since the 80s

[@Kevin-xy3yr]

The other way around, they took a gas engine and made it a diesel.

[@marcochavanne]

@@Kevin-xy3yr untrue but that is the rumor. I worked on a lot of them in the Air Force. Terrible design but they weren't just a gas engine they tried to cobble diesel parts on.

[@nm-qt2hb]

​@@marcochavanne They were 350 Oldsmobile gas engines that converted into a diesel engine. Cast crankshafts and rods. The lower end didn't hold up well, also tons of oil leaks.

[@samgford]

​​@@marcochavanne you worked on Oldsmobile passenger cars in the Air Force? That's where they did it. It wasn't the 6.2 and 6.5 Detroit diesels that it was done. It was a 5.7l in Oldsmobile vehicles. Look up LF9 Oldsmobile diesel on Wikipedia. It was indeed true and not a rumor that GM tried it.

[@Mattman2500]

I'm a 6.4L Hemi owner. I drive about 12k miles a year, and almost half that is towing 10k+. I have zero interest in a diesel. So the 6.7 gas has my interest.

[@jdtravelers1361]

I am in the exact same boat. Looking to move to a Cab Chassis in 2026. If Ram offers this as an option it will be them, otherwise F550.

[@DJ-ve5lr]

It would be interesting to see how much of a gov fine there is for building diesels when they also offer same engine but gas for $10k less? Or somewhere in between.

[@mikebrownell8121]

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.
