Cummins Makes Its 2 Millionth Engine

By Dave Lee

Cummins has built its 2 millionth diesel engine for Ram Trucks, the company announced Monday. Don't expect to see that milestone motor in a truck, though: The 350-horsepower, 6.7-liter six-cylinder turbo-diesel will go on display and tour the country.

"The Ram Truck-Cummins diesel partnership is one of the industry's most enduring and certainly fitting of such a tribute," said Fred Diaz, Ram president and CEO. "Both companies have benefited greatly, but Ram diesel customers are the real beneficiaries. Every day they experience the toughness and capability a Cummins-powered Ram can deliver."

Cummins began supplying engines to Chrysler Group in 1988. When it launched in 1989, the engine was rated at 160 hp and 400 pounds-feet of torque. In 2013 Ram heavy-duty pickups, the top-of-the-line Cummins HO makes 385 hp and a class-leading 850 pounds-feet of torque. Diesels make up nearly 80 percent of Ram HD sales.

"I am immensely proud of our association with Cummins," says Bob Lee, Chrysler Group vice president and head of engine and electrified propulsion engineering. "And I have no qualms matching our truck diesels against those of any competitor for performance and durability."

Last year, visited the Cummins plant in Columbus, Ind., and saw how a Cummins is born. Additionally, both Ford and GM celebrated their own select engine milestones as well. Now everyone has a reason to be happy.

Features in the Cummins engine for 2013 include a 10 percent improvement in fuel economy; dual-inlet Ram Active Air, which adjusts induction in different driving conditions; a "smart" exhaust brake; 15,000-mile oil-change interval; a new cooling system for improved performance; and a dual filtration system for enhanced durability.



Nice, pickuptrucks should do a thing on Ram trucks and Cummins

Duramax build over 1.5 million engines since 2001, and Cummins 2 million since 1989. I feel sorry for power stroke owners, they got gipped with quality!

That B Series Cummins is one ultra reliable engine. No denying that. Been solid since day one.

Chris, you got a link for that?

Only 2m since the 1980's? That's not a lot. Last time I checked Ram was the lowest on quality. Just ask Tundra Headquarters for the info.

I live in Columbus Indiana it's pretty cool see test truck driving around tow all day, semi trucks with cummins stickers on the side they have parking lots filled wit test trucks

Does Ford still own a huge stake in Cummins? I remember for years Ford wouldn't let Dodge build crew cab trucks while under contract using their Cummins engines. Did Ford sell off what they owned?

Cummins is the only thing a Dodge truck has going for it. A Cummins engine in a Dodge truck is like a diamond in a Goat's Arse.




Bottom line is, powerstroke can't stand close to Cummins or Duramax!

"Cummins has built its...."

You didn't build that.

If you've got a business, you didn't build that. Cummins stole from you. Now we gonnaa steal from Cummins.

The rich and Cummins didn't do anything on their own. We did it for 'em. You did it for 'em and you didn't get paid. You got stolen from and you got used. It has nothing to do with roads and bridges or infrastructure. Keep Obama in President you know!

Mikes FX4, that's a long-dead fallacy. Ford owned approximately 7% of Cummins common stock (the same stock you and I can buy from any trading firm) in the 90s while they still manufactured class 7 and 8 heavy trucks. It was an investment made because Ford used Cummins engines as the standard offering in those trucks. When they sold that line to Freightliner (which became the Sterling brand), Ford sold that stock. Ford had absolutely no say or control over the Cummins-Chrysler relationship, or whether Ram offered crew cabs (that was Chrysler's choice, not Ford's command).

The original 5.9 Litre Cummins was part of a joint venture by Fiat in the European Engine Alliance in 1996. Fiat got their Tector engine a clone of the Cummins from that partnership. I do not suspect that Fiat is going to replace the 6.7 Cummins with its own engine, but I think tey will use other Fiat Diesels in other Chrysler products.

Speaking of the 5.9, in 2008, Cummins was a named defendant in a class action suit relating 1998-2001 model year Chrysler Dodge Ram trucks, model 2500 or 3500, originally equipped with a Cummins ISB 5.9 liter, diesel engine built using a pattern 53 Block.[4] The case has been settled but some qualified Chrysler owners may receive $500 for repairs to the block, which was alleged to crack and create a coolant leak.

I have not owned a diesel, and not realy in the market as of yet, but I do know if I did buy a new diesel, it would be a Ram/Cummins, if I were to buy a used diesel, that would have to be up to the truck, you know mileage, useage and all that, but I do know better that to buy any 6.0 PowerStroke! and if it was a Ford it would have to be one a the last m/y 7.3's or a 6.4-6.7, and then it would have to have led a very pampered life, and have very little mileage, and as far as a Chevy/GMC DuraMax, again it would have to have led a pampered life and have little mileage, and NO way have ever had a plow! I woul like a new Ram 6.7 standard output with a man.trans! after all how much power do you realy need! or should I say how fast do you need to go? and at any rate you can get a lot more out of the Cummins 6.7 anyway after the warrantee anyway, and the same goes for the rest of them. There is a guy out here with a 2010? with a 6.4 F-250 and he has got that thing all tweaked out, and does that truck ever run! it smoked my E/B from the get go! and he gets 15-20mpg!!!!, before he did anything though, it was a fuel hog! he was luchy to get 12mpg in town and 18hyw, but the truck has always run pretty good, then there is the guy with a 5.9 Dodge 3500 man.trans all tuned up, (black smoke and all), let me tell you that is a monster!! he can leave the line with all 6 tires burnning up! needless to say he has a LOT of $$$ tied up un the engine, trans, and rear-front ends! and it sounds like nothing I have ever heard before! Just goes to show you that for now the Americans have the domestic market all sown up!

The 5.9L came about from Case Corporation approaching Cummins to come up with a line of engines to replace their aging tractor engines. Cummins would also sell the engine on their own, such as to Dodge for use in trucks. There are 3,4,6 and a big 6 that came from this program. Cummins wanted to push a v8 instead of what would become the 505ci big six but did some analysis and saw the big 6 a better fit. The plant in Indiana, and design of the engines was started with Case and Cummins money. This engine is actually began life as a Consolidated Diesel Corporation (CDC) engine the partnership of Case Corp and Cummins. The plant was the most state of the art at the time and the engine was one of the most efficient in the industry. Parts commonality across the 3(3.0L),4(3.9L), and small 6(5.9L) kept prices at rock bottom. This is one versatile engine line and I wonder how many engines were sold of each variation since. It has been put in almost anything and everything.
Eldon Burnbaugh a former engineer at Case up until the Case, International merger has a nice write up in volume 2 of his Case history book, where he mentions what I said.

@robert ryan

After reading that article you shared it is interesting how this came full circle. How all the parties once collaborated together, then began to go their separate ways wound up working together again. And Fiat owns CNH, which has Case, who still uses the 3.9L 4cyl in their backhoe line, and dodge which uses a variant of the 5.9L from CDC.

That newest Cummins Ram, BTW, the one with the new Aisin transmission, is an absolute beast. In their own testing, they are smoking the F350 on the Davis Dam pull. Going to be exciting when we get an independant rematch.

If they are doing the testing then sure they are going to smoke everything put in front of them. You don't put your own test together and then let someone else smoke you!!

If a diesel was a necessity for me, hands down I`d be buying a Dodge.

They're only putting Aisen trannies in the 3500s.
I love the look of the new Rams. They've upped the quality! Interiors, durability, etc. Although, I'm pretty disappointed the EPA is slamming the diesel world. It's a shame they have to put egr's and def crap on them now adays. Really killing fuel mileage and durability. Even so, Cummins will always make the best diesel engine.

WOW! with 2 million engines, they are going to have to make 2 billion Head Gaskets!!!

@K- its called benchmark testing. Everyone does it, and you sure has hell don't run crooked tests. WE're not talking about any PRBS here. This is internal testing.

Kudos to Cummins.
I do recall reading about #53 blocks. Those were casted by a Brazilian company.
The best Cummins block was one made in Mexico. I think that was known as the #56 block.

I do wonder if Fiat would consider one of their engines in the Ram HD's. That may be a non-starter since Cummins is what sells Ram HD's. 80% of them have a big "C" badge.
Fiat could bring in Fiat diesels for 4500 and larger trucks or for the new vans.

@Robert Ryan,

The Cummins 5.9L is not due to a 1996 joint venture with Fiat--it has been offered in Dodge pickups since 1989.

Cummins makes good engines, but I think their engines are commercially and industrially orientated at the moment.

Future diesels will be more like Euro diesels, they will be higher in power/torque, use much less fuel and rev out more, especially for small diesels up to 4.5 litres.

I can't really see current HD engines surviving for many more years. They will become 2/3s their current size and put them into the light diesel class. This will achieve 2 things the first is to reduce costs and the second will improve fuel efficiency well beyond what they are currently obtaining.

I would think the average diesel performance in less than a decade will be similar to the 4.2 litre V8 in the Porche. In Australia Kia currently has a 2.2 litre diesel with 190hp and 330ftlbs of torque, this is a European designed engine that is cheap.

Right now this engine would power a HD upto at least a F-450, that's a 4.2 V8. This is the future of diesels.

Read the link I have provided and look at the weight of the vehicle, fuel economy, and performance, quite staggering.

Quite expensive too, Al

LOL Jason, trying to sway some folks into buying a Tundra? No thanks, those that buy HD Rams mostly buy them for work, unlike the Tundras that can't slow down once you put 1000 pounds in the bed. But keep trying! LMAO! Last ditch effort as the Tundra sales start to totally fall!

@Dan, More Flames, More Fires, More Ford Garbage!!

Navistar slaps Ford with $2 billion lawsuit.

Ford has not been having much luck with the 6.4-liter diesel engines for its Super Duty trucks of late. In the latest twist of a saga that began in January, Navistar, the company that makes those engines, had added additional charges to its $2 billion counter-suit against Ford.

Navistar has been the exclusive maker of Ford's Super Duty diesel truck engines since 1979. In January of this year, Ford sued Navistar over the price of the engine and excessive warranty claims. In February, Navistar halted shipments of the just launched 6.4-liter engines, saying Ford had stopped paying for them. Ford got a court order to compel Navistar to ship the engines (which Ford paid for) -- then Ford had to recall more than 8,000 trucks because customers were reporting tailpipe fires. Navistar has now filed a counterclaim that seeks more than $2 billion in damages, and alleges that Ford is planning to develop its own diesel engines prior to 2012. There is no indication as to which party, Ford or Navistar, has a better case. For now, though, while the engine issues can't be good for Navistar, it is far more damaging for Ford to have to deal with these kinds of problems with its newly-launched bread-and-butter vehicle.

@TRX4 Tom
So were the diesel we are running now a decade ago, some didn't even exist. As I stated this is in the future.

@TRXTom - a while back I looked at most of the mid-sized European diesels available in SUV's in North America. Most were in the 3.5 litre range. They all posted similar performance figures when compared to the gas engines offered in the same vehicles. MPG was 20 - 30 % better as well. All seemed to fall into a 3,000 to 4,000 dollar price premium. Those engines would neatly split the difference between a gasser and the current crop of HD diesel pickups.

Sure, a Porsche Cayenne is expensive, but that is the case regardless of the engine under the bonnet.

"The 5.9 litres (360.0 cu in) 6BT, aka the Cummins "12-valve" was the first member of the "B" engine family to be used in a light truck vehicle. The 6BT used Robert Bosch GmbH fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BT's were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard. This engine started life in 1984 designed as an agricultural engine, for use in Case agricultural equipment.[1][full citation needed] After 1989, the 6BT engine was adapted to be used in light duty, medium duty and select heavy duty trucks and buses"

. Case is part of CNH a company owned by FIAT. I know they developed the 5.9

What confuses this more:

"And here we come back to the intended Chrysler-Fiat engagement, if not eventual marriage. Under the banner of what has, since March 2005, been Fiat Powertrain Technologies (FPT), the Italian group produces automotive diesels in almost every power bracket. Most significantly it offers the 4- and 6-litre Tector range. These are engines developed during the late 1990s under the EEA (European Engine Alliance) joint venture between Fiat and Cummins. THE FIRST TECTOR ENGINES WERE IDENTICAL TO THEIR CUMMINS ISB COUNTERPARTS , differing only in their fuel system electronic controls.

Whether the ISB Cummins and Tectors are further developments of the 6BT engine done by both Fiat and Cummins is probably a guess, but at least both engines were identical at one point.

@Robert Ryan - great link. It would therefore be incredibly easy for Fiat to replace the Cummins. There would be 2 reasons stopping them:
1. Contractual obligations
2. Alienating tradtional HD Ram truck buyers

Here is a wikipedia link that actually is quite good in describing the problems that you are talking about with I-5 engines.

I really don't know how they balance out the inherent harmonics in the Ford Duratorque I-5 diesel engine. But there are a lot of engines that have used balance shafts other than 5 cylinder engines.

Interesting, I'll try and find out. But I do know my engine is much "smoother" than a 4 cylinder in both delivery of power and and vibrations. Hmm?

5 cylinder engines are actually incredibly well balanced. That's why Mercedes used them so extensively, even where a gas I6 fits. From an engineering stand point, there is absolutely nothing wrong with an I5. Really, the only challenge is some perception that an engine ought to have an even number of cylinders.

93,000 trouble-free miles on my 2007 6.7L so far. The engine is solid. I hope they keep the inline six configuration. I like towing 16,000 pounds up steep hills at 2100 to 2500 rpm (redline is 3200) rather than screaming at 3800 to 4000 rpm like my prior V8 diesels did. Sweet, sweet engine, that Cummins.

No wonder we had problems with our Case backhoe. It was a Fiat. Fiat-Ram. Fix It Again Tony.
