Putting the 6.7-liter Power Stroke® Back on Top with a Power Upgrade
AUG
03

The 6.7-liter Power Stroke® V8 turbocharged diesel engine is now rated at best-in-class 800 lb.-ft. of torque and 400 horsepower. This is an increase of 65 lb.-ft. of torque and 10 horsepower compared to when the all-new Ford-built engine went on sale in April of 2010. Current 2011 Ford F-Series Super Duty® diesel owners can get the increased performance through a free dealer-installed software upgrade to the truck’s powertrain control module.

To get the inside story on this power increase, we spent some time with Adam Gryglak, Ford Powertrain Chief Engineer. Adam is often referred to as Dr. Diesel and the father of the all-new Ford-engineered and Ford-built Power Stroke engine.

theFordStory: What exactly will Ford be offering to owners of 2011 Power Stroke Super Duty trucks?

Adam: The 2011 Super Duty is already one of our best products. We have seen a substantial improvement in overall sales. With this torque and power upgrade, we offer class-leading torque with 800 lb.-ft. of torque, up from 735, and we increased horsepower from 390 to 400.

What did you have to change in the truck to achieve the higher torque and horsepower numbers?

The change is made entirely in the calibration, which is basically the programming of the powertrain control module that controls fuel delivery. The engine has the basic foundation to operate there and ensure outstanding durability. We just needed to upload the latest “app.”

What did it take to create a new calibration?

Since this an all new engine – Ford-designed and built – we had mapped the engine at many various calibrations during the course of engine development. That means that we had the data already. We had also already performed durability testing and validated the powertrain at these higher levels.

Will customers be concerned about using a calibration that didn’t go through the same rigorous testing as the rest of their truck?

The revised upgrade went through all of the same rigorous testing, and everything meets all of our internal standards.

Give us some insight into what conversations went on inside Ford when GM announced its numbers?

Having developed an all-new engine, we knew there was more potential in this engine. So it didn’t really alarm us when GM announced its numbers.

The original power and torque numbers were based on what we thought would be the right offerings for the truck and the market when we launched the truck. Behind the scenes, we were already working on more performance improvements. We simply decided to deliver more value sooner rather than later.

Did you or someone your team anticipate GM one-upping the impressive torque and horsepower numbers of the new Power Stroke?

We recognized that we would be announcing our numbers first, and we did think that they might take advantage of that. But Super Duty is number one in the segment, and we expect to stay there.

What will the Ford team do if GM raises its numbers?

Ford is all about value and customer satisfaction. We are always looking to improve our product and time will tell what we do next.

Why not launch with higher numbers earlier in the year?

We had to agree with what would be the best targets a year ahead of time so the complete powertrain and vehicle would be stable heading into launch. To do so, we chose to be more conservative. You can see by the initial consumer response that we made the right choice. The vehicle is doing very well in the market.

Why is it important to have the best numbers? Isn’t there more to the driving experience than just having the top numbers?

The numbers are important to our customers. The customer-impact of these improved numbers gives them torque reserve. They’ll experience less downshifting while they are towing. They should also find a fuel-economy improvement of at least 2 percent, which is a full 20 percent better than the 2010 model Super Duty with the previous generation Power Stroke engine.

What’s the process for owners of the 2011 trucks in order to get the new calibration?

Current owners of vehicles with the 2011 Power Stroke will get a letter that tells them exactly what to do. Basically, starting August 31 and continuing for 12 months, customers can go to their dealership and receive a 30-minute software upgrade for free. This is the first customer loyalty program of this kind.

Fasimoli Fosi I am a loyal Ford customer and I was very disappointed to read Motor Trend Magazine ranked GM as the number one truck over Ford Super Duty. On the bright side, Popular Mechanic ranked the Super Duty as the best truck above both Dodge and GM. I feel Ford should include Popular Mechanics results in their new commercials.

don Yes ford did borrow money. the old fashion way, they also sold of several brands from their pag, like jaguar, aston martin, land rover, and now volvo. the trimmed the fat, produced high quality vehicles that the public was demanding. It is now paying off.

Jeremiah Ford did borrow money just before the markets went all to hell $16 Billion from Goldman Sachs, JP Morgan Chase and Citigroup thats the only reason they didnt have to borrow money from the Goverment pretty lucky or just good timing. P.S. they were losing about $750 Million a month!!!! Dont get me wrong I like Ford way better than GM but I bought a CUMMINS the dodge just came wit it : )

Chris Brown I bought a new Powerstroke F-250 in '97 and while the motor is strong the ole gal is showing her age. After the 6.0 debacle and the limited success since I'm on the sideline until some durability data shows up. Any comments from folks who have put some real miles on one?

Jim Ghilardi Does the new 2011 powerstroke engine have an exhaust brake?
4 year(s) ago via
Adam Bought a brand new 7.3 F250 in 2002. Been waiting on an engine worth trading for, and sounds like you have it. Lack of a REAL manual transmission is a deal breaker for me, though. PLEASE bring back the 6 speed manual trans, with an actual "on the floor" 4x4 shifter. I can get 17mpg on the highway with the old girl set up with a manual trans, manual transfer, and locking hubs. For everyone whining about mileage, you should check which rear-end your truck has. Differential ratios will make a huge difference. Also, please bring back the diesel Excursion. Have kids now, looking at having to buy an old one.

Del The new 2011 Super Duty's look fantastic and Ford's new engine is just awesome. We have a 2004 Excursion with the 6.0 diesel and love. I'd trade it tomorrow if Ford made the Excursion again. Some of us have large families and also need to tow things like campers, enclosed snowmobile/motorcycle trailers. Nothing works better than a diesel but we need seating for more than 6. PLEASE Ford bring out a new Excursion. Just look at the resale prices of older diesel excursions and you will see why you need to make a new one! Lot's of us are hanging onto our old ones longer than any other vehicles we have owned because there is nothing to replace it.

Trent I want a cheese burger without the cheese. Easy solution, and youll save lots of money. Get an XLT and have the King Ranch leather put in, you can even buy the King Ranch emblems to fool others.

michael fischer Im not sure if it is all models or just some but they offer a tap shifter on the selector. I know it is not as good as a good old REAL manual 6-speed but they still count it as one. You cant find many new U.S trucks equipped with a true manual these days. I think you can get a manual in a ranger maybe one in a dakota and the colorado. but im not sure about those

Derrick Soo I find it hard to believe that you can get 20+ MPG. I stopped buying Ford trucks because of the terrible MPG I was getting, 10.5 MPG. I owned two, '05 & '07 F-350's. My contractor buddies got the same as I did, so how did this come about? I really liked the Ford trucks, but with getting only 10.5 REAL World MPG, I stopped buying. Oh BTW, that number is unloaded and NOT towing anything.

pete Boyle I have test drove the truck, love it but the problem is it is not offered with a manual trans. There is still a good number of us that prefer a high end truck with what we want in it.

jim saxon why is ford saying that the horsepower in the super duty 6.2 is 385 and 404 lb of torgue, while the horsepower in the F150 6.2 is at 411 and 434 lb of torgue? is there going to be a new calibration for the 6.2 in the super duty like the calibration done to the powerstroke 6.7?

jack 2011 F350 a month old with 3500 miles on it with a life average of 15.7 MPG. 2000 miles are heavy towing 10,000 lbs+. I just had the upgrade and notice the power increase. Empty on the highway in upstate NY I get 19.7 on my 60 mile round trip to work. Owners of the new truck if you leave the Trip B alone you can watch the MPG average for the life of your truck not just the tank if you have the information center option.

Steve ??? Are you kidding? Of course your oil pressure light is on before you start it. There is no oil pressure when it is not running! All cars will do that if you just turn on the key, but don't start it.

Monter S. The question is if you can do this for the 6.7 why not do it for the 6.4. Ford has left all that bought these trucks hanging.

Brooks Carmichael I have the new 2011 F-350 4x4 dually. I am impressed with the power and the milage. I made an inital drive of 700 miles and got 19.7 mpg. I pull a combination living quarters, horse trailer and got 13 mpg. I was hoping for better milage with the trailer but still very impressed . It was better then my 2006 F-350 with a 6 speed manual. Any improvement with milage is important with today's fuel prices. I am hoping the price of DEF comes down.

Luis Urdaneta Love the new heavy duty F-series, the new gas and diesel engines are awsome ! Will the 6.2 liter receive an upgrade too from 385 hp to 411 hp at least (like the raptor) ? Thank you !

hww how do you get 24-27 mpg on a 20 mile ride. 20 miles will give you no idea of mpg.
4 year(s) ago via
John Clary I traded my '02 7.3L F350 for an '11 almost as soon as they hit the showroom. the '11 is a full-dress lariat and it is an awesome truck! I have to carry a big stick to beat folks (mostly guys) away from it to keep from getting drool all over it! if I'm to believe the computer, I've been seeing 20 in town, 27 hwy. I haven't figured mileage the old fashioned way. my wife says it's like riding in a top-end SUV. love the truck!

Curt Bancroft I have had a 2011 F-350 FX4 crew cab lariat since the end of May, and driven 5,500 miles. The fuel economy I have experienced is 12 to 16.2 actual M.P.G. I usually carry a load of 1,500 pounds, on average, of cargo and equipment, and I am not heavy footed. Nice truck, but not the economy I was expecting. My 05 6.0 gets about the same as the new 6.7.
4 year(s) ago via
Jerry Page I am a Ford Diesel Tech. I have test drove 3 of these trucks now. While my drives have been fairly mellow, no heavy towing, I have seen the fuel economy numbers as high as 27MPG in a F-350. This was just on the instant, my average was around 23-24 over a 20 mile test drive. Very impressive if you ask me. Plus with additional power coming and a slight fuel economy increase Ford has control over this power/economy game over GM and Dodge. I hope to see even more increases when GM increases their power.

Greg Richardson Love the truck. I don't own one, but I am looking at it. Dodge has played their last fiddle string with me, and GM is a non contender. As Leroy indicated, fuel mileage is the real kicker to the deal, and I am NOT willing to put $55,000 into the lottery to find out on my own. Your answer of 2% and 20% overall is great, but lets get down to brass tacks. What in real numbers is the estimated fuel mileage of the 6.7 powerstroke, and how is it affected throughout the series, i.e. 2500 vs 3500 vs 4500
