Ford Power Stroke Hits the 500,000 Mark

67PS Engine II

Ford Motor Co. hit a milestone Tuesday when it installed the 500,000th turbo-diesel 6.7-liter Power Stroke engine into a Super Duty chassis at its Kentucky Truck Plant. The engine construction was moved in-house several years ago after a rough breakup with the previous supplier, International.

The V-8 diesel engine has many industry-first design features, not the least of which was the first application (for anyone in the auto industry) of the inboard exhaust and outboard intake runners that made the engine much more efficient. This allowed the turbocharger to be mounted in the valley of the engine where heat and vibration could be better controlled. Other features include high-pressure piezo injectors, six head bolts, B20 biodiesel fuel capability, aluminum heads and a compacted graphite iron engine block along with many more.

The 6.7-liter Power Stroke currently produces the most horsepower of any Big Three heavy-duty truck makers with a rating of 400 hp at 2,800 rpm. However, it is bested by Ram’s current 6.7-liter Cummins inline-six-cylinder in the torque department: The Power Stroke produces 800 pounds-feet at 1,600 rpm, and the Cummins produces 850 pounds-feet at 1,700 rpm. We should note that Ford is the only manufacturer that designs and builds its own diesel and transmission combination; both GM and Ram Truck use outside suppliers.

Updates for the 6.7-liter Power Stroke will be announced at the 2013 State Fair of Texas this week.



Way to Go Ford keep it up!!

Driven one. As a Duramax/Allison owner I can say the 6.7L is an impressive engine, as is the transmission (although it's sort of a copy of the Allison). Still too new to make long term comparisons to the Duramax or Cummins but so far it's the best Ford diesel since the 7.3L.

Way to go Ford.

Still wanting to see the engine last 500,000 mile mark.nThen it will be good in my book. Glad it didn't turn out to be another 6.0....Anyway GJ Ford.

@Bryan- in the case of GM, you're only half right- Allison was part of GM when they started using the 1000 series trans. And the Duramax was developed WITH Isuzu- who were also partly owned by GM. The partnership has since expired GM now runs its own Duramax operations.

Does anyone here actually have over 100K on a 6.7? How are they holding up? All engines work great when new. What I'd like to know is how they are working as the miles rack up. We already know there are tons of Cummins diesels running around with 500,000+ miles on them. Let's see the 6.7s when they have some age on them. Then and only then will they be worthy of the label "good engine".

Mr. Knowitall, Until GM comes out with a new one the statement still stands.

Awesome Ford! Can't wait till later this week to hear the news! I love to see all the manufacturers having success.

@WXman They look to be okay engines at least better then the 6.0 and 6.4s. Just seem to be turbo problems mostly and some blown engines.

Looks like there is some trans issues too, but over all no big stink yet like the 6.0

Regarding Chevy teaming up with Isuzu for the Duramax...
Isuzu is the world's #1 diesel engine manufacturer.
It was smart for Chevy to team up with a manufacturer that knew how to mass produce a modern diesel engine.

I heard about some results of testing from a company that makes performance chips for vehicles. They test a lot of different engines to see how much power they are capable of producing before it is too much for the engine. They do the testing obviously so they can give it a good tune without destroying the engine. The 6.7 they say can reliably put out an incredible amount of power. More than anything they've seen before. Time will tell but I think it will prove to be a good engine.

Our family farm has an 11 F350 dually and a 12 F450 dually with this engine, and so far, 11 has around 90k miles, and 12 haS 55K miles, and they have been exceedingly reliable. Efficient too, the best we have seen in a long time. They are incredibly powerful, make towing an easy task. We consistanly haul four horse trailers long distances, and they do so without a sweat. I have to say tho, our two 6.4's are excellent, tho not as efficient. the 08 has 150k trouble free miles, and the 10 has 100k trouble free miles. We also have two 6.0 diesels, one an 05 with over 200k miles (had a turbo and 8 injectors replaced, other than that, fine) and an 06 with almost 200k miles (8 injectors but otherwise fine) we are very pleased with our Fords. The 11 7700 Ecoboost is pushing 80k miles without a hiccup. We use these trucks very hard and they just keep on going.

@ Bryan, also only half right about RAM and their 68RFE transmission for the Cummins in the is an in-house Chrysler designed and built transmission. You could argue that they have the Aisin in the 3500 pickup, but keep in mind the Aisin trans is only included with the optional 850 ft/lbs Cummins. Yes, the Aisin is the only trans for a Cummins in a RAM chassis cab, so no argument there. Nonetheless, facts are facts - - you weren't 100% correct on your statement as others pointed out with GM and Allison transmissions, or RAM too.

Here's a 6.7l with 500k miles already.

So far this engine is turning out to be their best diesel since the 7.3l. Beats the hell out of the 6.0l and 6.4l. You don't need to take the darn cab off anymore to work on them.

How many Duramax's has GM rolled out? Bet its a lot more than 500K but hats off to Ford for finally getting it right this time. Have many friends that were bit by the 6.0 bug...

You're only half right. Mark Willaims is 100% right. The key words are: designed, built and COMBINATION.

This was a statement by Mark Williams. The combination is what he is referring to. If you have a tranny built and designed in house, but not the engine, then you do not thave the COMBINATION.

As for GM, who owns the GM company now doesn't change the facts that the engine design dates back to the early 2000's. If GM builds and designs a new Duramax then they will have the in house designed egine part of the combination.

My source:
"The new Duramax diesel engines are built to meet new clean-air regulations, plus they feature other key improvements in technology and capability. Like today’s Duramax, the Isuzu-GM joint venture engine will continue to be available in two versions.

“The new Duramax diesels are based on the same engines that have been around since 2001,” said Gary Arvan, a GM diesel powertrain engineering chief."

If you disagree with the statement and believe Mark Willaims is wrong and the Ram has an in house desgined and built engine AND Ttranny COMBINATION, please do not point it towards me and inform Mark Williams with the facts.


Dooms, yes you do need to take the cab off to work on the power stroke.

I have read that the Ford Lion diesel was used as the basis of the design for this engine.

The PowerStroke isn't a copy, but an 'extension' of the Lion V6. The Lion is British in origin. As for the truck, well it's a truck.

I have driven a SuperDuty and found this engine to be very addictive. Plenty of power and torque.

But did I use that power and torque or did I need that power and torque?

No, I think the HDs across the board should have a lower power diesel option as well. 300hp and 500ftlb should be enough for most.

A smaller diesel of this size will make it cheaper to buy a diesel HD and enjoy the economy of the diesel.

I have notice some who whine about the additional cost of the diesel. How much is spent on the drivetrains. The smaller diesel could run existing V8 components.

It will still have the power to achieve most of what is required for a work truck.

But this is a nice diesel.

One thing I think is interesting is how often every pickup engine undergoes a refresh or even a complete replacement. Consider, say, the old Ford 300 I-6. It was offered in F-series starting in 1965 and was produced all the way until 1996 (was it made for the last '97 F-250HD/350's? Somebody help me out here)--that's 31 years! The same was true of other companies' engines. And sure, there was a lot of changes made over that time period, but it was still the same basic engine underneath.

Then you look at modern engine-building in pickups--if you keep an engine for more than 5 years without updating in some way, your model is helplessly outdated.

Not really sure what to make of that. Could be a good thing, could be a bad thing. Just thought it deserved a comment.

And congrats to Ford on achieving this milestone. Heck, congrats to everybody with where they are today! Except maybe Nissan--and then only until 2015.

2015 will be an amazing year. Brand-new F-150, brand-new Super Duty (will they look similar again? Probably not.), brand-new Titan, AND Star Wars Episode VII! (Not that that's really relevant here, but whatever.) My body is ready.


Nope. Every repair on the 6.7l can be completed with the cab on. Dealerships will still take the cab off because it makes repairs easier, but it isn't required.

This should make the previous Ford Diesel owners with pending warranty claims happy.

I have a couple of friends that bought V10 gas, due to the bad experience they had with the previous Diesel's.
Ford lost alot of trust with its customers over Diesel warranty claims.
Our Salesman has a 2012 SD.
He was complaining that the extended warranty wasn't from Ford, as it had been in the past.
When its in the shop, it can be down for a couple of days waiting on approval.
But overall, I don't think he has had any major issues.

Still need a new truck to put this engine in.
Am I the only one that notices the doors rattling in their opens over small bumps?

@David - good point.
Part of the reasons engines have been changed so much is due to emissions and MPG standards.
Another reason is the access to information. The internet and mass media put more pressure on companies to come out with the "latest and greatest". Short attention spans and the need to have the "newest" drives development. Many people expect vehicles to be like cell phones, they expect new versions all of the time.
I'd prefer to see a drivetrain stay in service a long time. There are always gremlins to be worked out on any new model. Engineers can do computer simulations or dyno runs until Armageddon, but once a product ends up in the hands of Joe Public anything can happen.
I was looking at TrueDelta and the F150 showed the least amount of problems in 2009 and 2010. That was basically at the end of the modular Triton engine lifespan. In 2011 and 2012, they showed an increase in problems.

Yes 500'000 and they still can't out perform the old dmax...maybe ford could keep this news for himseif ???

Outperform? Who is the one who couldn't show up at the King of Beasts monster tow test?

The first to have inboard exhaust, and outboard intakes? wasn't the GM 4.5 Duramax engine almost made and brought to market before? but the design was ahead of the Powerstroke? maybe the word brought to market have something to do with this argument.

“To me it’s not a luxury car, it’s just a truck,” said Dan Edelman of his 1996 Dodge Ram 2500 4x4 truck -- a truck that has more than a million miles on it. That’s 1,000,000 miles – with six zeroes. While the auto industry seems to be distracted by comfort and style, owners like Edelman buck the trend; valuing dependability and keeping their vehicles running well beyond the first 500,000 miles.

Dooms, you are wrong.

I've worked on several, pretty much anything beyond taking the intake off means that the cab NEEDS to come off as well.

@ ASE Certified, Your right my friend Ron told me to change the spark plugs in his 02 Ford F one fitty. They would have to remove the cab. lol :((

before anyone gets carried away with the Cummings comments-please remember-each generation of cummins is as different from each other as a 7.3/6.0/6.4
