Chrysler Gives Cummins a Big Thank You

9 Ram HDa II

Cummins Inc. was recognized by Chrysler Group LLC as a 2013 Supplier of the Year at the 2014 Annual Strategy Meeting and Supplier Awards Ceremony in Auburn Hills, Mich., last month.

Cummins actually received two separate accolades at the award ceremony: Powertrain Supplier of the Year and Technical Cost Reduction Supplier of the Year. Chrysler has been holding this event for several years, but this is the first time Cummins has won two awards in the same year.

"Our supply base manufactures more than 70 percent of the content on our cars and trucks," said Scott Kunselman, head of purchasing and supplier quality-Chrysler Group, in a statement. "It is critical that they are as focused as we are on creating innovative, high-quality vehicles that our customers want to drive. Our award-winning suppliers, like Cummins, have proven themselves to be motivated, capable and excited to be on the Chrysler team."

The suppliers were judged on performance in areas such as quality, delivery, cost, warranty and partnership. Cummins makes the 6.7-liter inline-six-cylinder turbo-diesel for the Ram 2500/3500 heavy-duty pickups and the 3500/4500/5500 Ram HD chassis cab, and has been the diesel option for Dodge/Ram trucks for 25 years.

Congratulations to Cummins. Best diesel in the best truck.

Kudos to Chrysler for recognizing Cummins! Great engines, great trucks, and super durable turbo chargers unlike the ones installed on Ford engines!

Ford had a good relationship with Navistar until they tried blaming all of the issues with the 6.0 and 6.4 engines on them. It is interesting how Navistar did not have any issues with these engines in their own trucks. Why take the blame when you can try to blame it on someone else?






They should because with out Cummins they would have been out of business back in the 80's.

If it wasn't for Cummins, RAM would be nothing!

According to the link below, the next upgrade to the ISB will have a "dual stage sequential turbo." Is this the same as a compound twin-turbo setup?

If you cannot build your own diesel, then you are at the mercy of the suppliers. Less profit for Fiat unlike GM and Ford who does supply their own diesels.

Congrats to Cummins!

@ Alex

Excellent question. I would answer that, but I think I will give our resident turbo genius, Turbo Yoda, a crack at this first. After all, he knows more about turbos than anybody. Although, I bet there will be a lot of Google hits about turbos on his computer to answer the question.

My sister had 4 F350's with the 6.0 and now her crews drive RAMs with the 6.7. Only a few minor problems in 3 years. Now she may have to go with GMC because of Mexico kidnapping one of our soldiers and flooding our boarders with orphans.

Really guys? Where would Ram be without Cummins? Where would the GM twins be without Isuzu and the Duramax? I don't understand why there is brand bashing in a post about a Manufacturer awarding their suppliers. I think it is great that some manufacturers will actually take the time to do this type of thing. I think they all need to do it.

As fulltime rv'ers traveling this country towing heavy fifthwheels for many years we had diesel trucks of multiple brands over the years. The last one was the only Ram with Cummins. Wow, if we hadn't recently stopped traveling after putting 107,000 trouble-free miles on that Ram 3500 I'd be considering a new Ram diesel. That engine is amazing. Some have said Ram should go to a V8 diesel. I sure hope not. That Inline Six has the low end grunt and allowed us to pull those steep hills at maybe 2100 to 2300 rpm instead of the 3800 rpm our diesel trucks from the other brands used to do. And this Ram never had to have any oil added between the 10,000 mile oil changes. And it got better mileage than our other trucks, both towing and not towing. When we sold the truck at 107,000 miles the doors still sounded solid when closing and the power windows made no noise going up and down. In other words, this truck felt like it was just getting broken in. Ten years ago I'd never have thought I'd be saying this about a Dodge. But nothing makes a believer out of me better than experiencing it. I have passed my thoughts on to other friends who are also rv'ers, but who drove other brands, and several of them are now very, very happy with their Ram.

It doesn't matter. What ever Cummins and RAM makes is the best.

The "Would you buy a Ram if it didn't come with a Cummins" debate has often come up in the diesel forums and around the water coolers. It usually comes out the same with more people being more loyal to Cummins over Ram and if Ram dropped Cummins then they would probably switch to which ever truck make offered the Cummins. This is why some bring it up, but I will have to agree with you that it is a bit silly. This also not the first time that Cummins has been Chrysler's supplier of the year. They have won it many times before, but has never been broadcasted on PUTC. That and the fact that the internet makes it easy to spread info nowadays versus just ten to fifteen years ago. Other makes also have their supplier of the year award every year just like Chrysler.

Well said sir! Nobody does it better than RAM trucks! They have all the bases covered and then some!

I agree Ram makes the best HD truck right now. But competition is a good thing and I hope we all agree on that at least. I'm looking forward to the 2016 Super Duty because it will make Ram even better. Chevy? They have lost the plot completely, but I hope they can manage to stay in the game to keep the segment growing and competitive.

GM was the largest owner of Isuzu when they developed the Duramax 6.6L and subsequently purchased all the diesel designs and rights from Isuzu as a part of their divestiture of Isuzu.

So now that Nissan is going to use Cummins, Chrysler gives them an award?

@Joe, many suppliers supply to multiple companies, that doesn't mean they're not trusty suppliers to each one individually. Chrysler rejected the ISV, they must have assumed that this engine was up for grabs. I don't think Cummins needs to sign exclusivity agreements.

The Cummings engine has a square-block shape, if it was designed as a more rounded shape it would be more efficient and smoother running and better cooling transfer in every part of the engine.

@RAZOR: your point is? By the way, some GM trucks are built in Mexico. So your sister gains what?

Chrysler and Cummins changed the truck world when they came out with the first turbo diesel.

There are truck buyers that bought Dodge trucks in the past just because of the Cummins. Nissan is smart to go with the Cummins. Isuzu makes a great diesel as well.

That put GM off the list as well. As long as an American Soldier is held in a mexican prison I will buy nothing made in mexico. That includes the Ford 6.7. We may have to do some research and buy a used truck and have it rebuilt. Like I said I can not understand why anyone would buy a product made in mexico as long as our Soldier is held hostage.

Buy there stock I did!

I will not buy from any company that is from a country that bombed pearl harbor. Scratch Nissan, Honda and Toyota off the list.

I will not buy from any company who sentences innocent Americans to death by fire, with trucks that SPONTANEOUSLY COMBUST. Scratch Ford off the list.

I will not buy from any company who builds crappy trucks. Scratch GM off the list.

That leaves only Ram.






Don't blame Mexico, they are just enforcing their laws.

Now I am not a fan of Mexico but if our government had any balls we would be enforcing our laws and not allowing all those illegals into our country.

If only you would direct that same anger at our own corrupt government.

I am the Turbo Sensei that taught Turbo Yoda everything he knows about turbo! Now I teach you....

What is a Turbo?

TURBO (voiced by Ryan Reynolds) is a speed-obsessed garden snail who, more than anything, wants to compete in the Indy 500.

Is Turbo Good?

Turbo does lots of things right when it comes to making an engaging, funny animated movie for kids. It's got a main character kids can root for and relate to, plus a menagerie of supporting characters who amp up the laughs (White Shadow, voiced by Michael Bell, steals the show). Kids don't care that the concept of a snail being allowed to race in the Indy 500 is completely implausible and full of logic problems. (Nor do they care that the tacos featured in the taco stand/truck aren't authentic.) They'll love the little details, like when Tito puts Turbo to bed with a packet of taco sauce for a pillow and a warm tortilla for a blanket.

Now you know all about Turbo!

Mexico just needs to become a socialist country. All the illegals would go back and jobs would come back here. Please Obama, be the president of Mexico!

@ Ram for the win .. you may have selective reading on RAM fire recalls recently, but your choice.

Me I support trucks mostly made in USA & their parts. I only see one truck on top ten, wait, only one truck in top ten... F150.

Chrysler's partnership with Cummins is one of the smartest business decisions they ever made and did a lot to save them back in the 80's.

To those who criticize saying that GM and Ford have "in-house" diesels now, are you forgetting history? Historically only GM has anything close to their own diesel and that was because Detroit Diesel was owned by them.

Back in the 70's and 80's, their "in-house" Olds diesels were a complete disaster. Additionally, while generally reliable, the 6.2 and 6.5 never gained the following the Cummins 12v did.

Ford used International diesels until the 6.7l and that partnership did not end on a good note.

All one has to do is to look at history and realize the following: 1) No, "in-house" diesel are not always the best idea and 2) Partnerships don't always work out as was Ford's case.

With that in mind, I think the Ram's relationship with Cummins is of vital importance for their continued growth and it also has helped Cummins to be the company it is today. The Cummins brand is virtually a household name. Is Navistar a household name? Is Detroit Diesel a household name? Maybe, maybe not.

Finally to address the speculation on why Ram didn't go with the ISV in the 1500's. I can think of at least 3 reasons:
1) It's not ready yet and Ram wanted a jump on the 1/2 ton diesel market.

2) It's more expensive to offer the ISV because of it being a Cummins, so that price differential might have the effect of inadvertently moving 1500 customers into 2500 territory.

3) The ISV will never get the fuel economy the 3.0 Ecodiesel does. FE is of vital importance in the 1/2 ton segment.

@HEMI MONSTER - agreed.

The 5.0 Cummins may be too big an engine for a 1/2 ton. Nisan and Toyota are rumoured to be going to use the Cummins and both companies do not currently offer a HD pickup.
Those 2 companies will most likely release a 1/2 ton that overlaps considerably with 3/4 ton trucks if not competing directly with them.

@Lou_BC "Nisan and Toyota are rumoured to be going to use the Cummins" where do I start

First of all you spell it "NISSAN"

Second of all "to be going to use..." is that even

Third of all "Nisan" will be using the Cummins....old news idiot...BTW WW2 is over!

And Ford will be using the following diesel....

RAM Big Horn 1500 - I agree with what your saying. America problems are not caused by the politicians. They are caused by the voters. I can't control how my vote is counted because of electronic voting but I can control where my after tax dollars go.
It seems that mexico's government is as corrupt as our government is. As soon as the our government reaches critical control of our lives we will be at the mercy of our law enforcement the same as the mexican people are at the mercy of theirs.
I came very close to buying a 2500 Mega-cab 4X4 with the 6.7. I wanted it bad but I could not bring myself to support the folks south of the here. Even though I like the RAM trucks my values keep me from purchasing one.
In my opinion Cummins is the best. The Ford engine still has a few years before it proves itself to me.
I have a number of relatives that have given there all for our country. One of my older brothers served in the Air Force for 42 years. I have two nephews that are pilots. One just got his wings and one has served 6 tours in Iraq and Afghanistan. Several other nephews have server on the ground knocking in doors. One was the gunner on top of the HUM V. He server two tours in Iraq and said he loved that gun. As for the USA all is not lost but we as a country are in trouble. To find out where we may be headed watch the first part of the movie Idiocracy.

@Lou, perhaps we should be calling the Titan diesel a 5/8 ton?





Sorry, I got side tracked and forgot about your question. Since Turbo Yoda is not smart enough to answer your question then I will.

No, a dual stage sentential turbo is not the same as a compound turbocharger. To understand why you need a bigger turbo and a smaller one, you must know the advantages and disadvantages of both. A small turbo can spool up quickly to reduce turbo lag, but at higher rpms it starts to spin too fast so the pressure has to go through the waste gate to slow it down not giving you any power at high rpms. A bigger turbo has very bad turbo lag because it take quite a bit of exhaust pressure to spin the wheel, but once that wheel gets going then it is able to run at higher rpm ranges.

In a compound turbocharger arrangement, you have a small high pressure turbo and a bigger low pressure turbo. They are in a series and the small turbo always feeds the bigger turbo. This type is a bit tricky and a fine balance between the two has to be achieved or it will not perform that well.

In a dual stage sequential turbo arrangement, the small turbo is used for low engine speed to spool up quickly. Then when a certain pressure or rpm is reached, it diverts all exhaust pressure to the larger turbo through a bypass valve letting it take over. Basically, the small turbo is for low engine rpms and the bigger one is for higher engine rpms.

Hope that helps.

If only you could make a living correcting typographic errors.

Too bad you have to entertain yourself as a troll.......... I'm sure you entertain yourself other ways but considering your cowardly approach, the other method of self entertainment probably lasts less than 10 seconds.


Ram For the Win=Hemi V8
He made the same Peal Harbor comment but he can't understand the world has changed since then with the U.S. Navy keeping a Nimitz Class Aircraft Carrier there.
Now I am going off on a limb and guessing that Hemi V8 is smarter than his comment but he want's to find a reason to dismiss the Japanese brands so he will grasp at anything which is very pathetic even for a fanboi. He could have just said he wouldn't by anything outdated or he just doesn't like the look of.

A very successful partnership.

That rotary dial shifter is so manly in the Ram pickup

@Lou BC

Not being very familiar with the 5.0 Cummins myself I'm wondering if you think the engine is physically too big or too heavy for a half ton truck, or if it's overly capable (too powerful) for a half ton.

Let me know.

@papa jim I don't see why the 5.0L cummins would big to big or heavy. I wouldn't think it be any bigger or heavier then a 454 which Chevy put in their half ton ss sports trucks back in the 90s or the old heavy 6.5L diesels.

extreme guts

extreme glory

rextremely durable turbos engines and trucks


ALL1 is only partially correct in his response.

A staged compressor setup along with IGV's will allow a turbo to spool up at a lower rpm, hence giving the turbo diesel a broader torque band.

This isn't tricky as turbine engines have been using multiple spooled engines for the last six and a half decades.

If you aren't aware Volvo is releasing a compound engine. ALL1 needs to use Wikipedia a little better.

A compound engine is the use of a supercharger in conjunction with a turbocharger, ie, the radial piston engines of old perfected this in the 40s.

What I see it the maximisation of the turbo charger. I would expect a dual spool turbo to bring on high torque from around 1 000-1 100rpm. This is significantly better than current light diesels which come in around 1 400-1 500rpm.

This would make the light diesel able to run at high torque loads at under 1 500rpm on the highway. Again improving the FE advantage diesel already has over gasoline.

This is also cheaper than a twin turbo setup. This advancement will improve turbocharging as much as IGV's had done.

This explains a little about turbo-compounds.

@Big Al

You say I was partially correct. What part of my response to Alex was incorrect?

@All1 and Big Al, thanks for your explanations. Sucks about Turbo Yoda :). No doubt the dual-stage sequential turbo will improve the power and delivery characteristics of the Cummins 6.7 substantially. With a bit more reading, it sounds like the low-pressure turbo will be a VGT, whereas the larger stage will not be. According to the Diesel Power, it could also be DOHC with variable valve timing. Well hopefully we see it sooner rather than later.
