No way or I should say they must have used the Lie O Meter to get that more Ford BS

If you believe that I have a bridge I will sell you!

Well, that ends all the debate... Ford DOES have the straightest antenna. !!!!... . too bad there wasn't a chassis dyno on-hand with some truly independent people to test these trucks after the fuel mileage race...

I would really like to see these trucks dyno'ed to verify that the fuel map is the same as the boasted 400 hp and 700+lbs. and that the regen system WAS enabled.

Hey, what if it is true? If it is total BS there are going to be some unhappy customers. As a Cummins advocate with 500k on my old 95 I have to say that it wouldn't bother me if Ford ended up building a better engine! That's great for America!



A friend of mine worked at Ford for some time and is now an engineer at Paccar. I asked him about the new Ford designed diesel and he had good things to say about it. He did not have such great things to say about the 6. 4! Time will tell.

I read somewhere that these no longer use the regen system, but instead use the urea catalyst system. This supposedly dramatically increases fuel economy. Still seems a bit too overblown, especially in real world driving.

The DPF is still used, but with the use of SCR (urea) the engine can be tuned to run cleaner with more timing and less EGR, so that regeneration will not be required as often. I think Dodge is on the wrong side of history with their adsorber strategy, which requires almost constant regeneration. I would not be surprised to see urea used in the future- with the accompanying MPG improvement.

Friend who was engineer at Foed and now with Paccar says this is unrealistic by a long shot for anything near reality. My guess is we all understand this. His internal sources say the truck will be upper teens. He's heard of this and said these events occur often and it's very possible with the perfect tune, driving in the sweet spot for the engine, lower speeds, light fluids, aired up tires etc.



I trust his comments as he worked on the diesel program at Ford. New engine he thinks has more promise than recent past Navistar / Ford mills.

Like mentioned above, I'd be willing to bet that fuel mapping was altered, no one would notice the horse power difference in an empty truck. I'd like to know how much they paid the testers also, I'd say almost anthing for enougth money. I wouldn't be surprised if the frame was probably boxed and full of fuel and the motor probably was drawing fuel from there as well so that the tank wouldn't go down as fast. Were the filters hollow?
