The 6.7 L diesel is built by Ford. The severed relationship between Ford and Navistar is the reason.

 

If thats the case, then the project isnt even being considered. The reality of it is that these trucks all must compete with each other. They also must be driveable in the sense that these modern engines deliver all the smoothness and higher rpm power exhibited by gas engines, then pull like hell when required by its owners. Thats the reality out there! A good number of these trucks spend very little time pulling or hauling and thus must exhibit the performance demanded by the consumer.

 

Yes, that has been the reality for many years. But as fuel prices continue to rise demand may change. I read today where Ford is adding Saturday shifts to the plant that builds the Focus due to increased demand. When consumers start buying based on fuel economy instead of power there will be a change.

In my worthless opinion the Superduty is the perfect place to test this line of thinking. Do you think a business cares more about their employees having plenty of power under the hood, or what they are spending each month on fuel?

 

I say its time for a medium speed torque monster like the big rigs, and make it an INLINE that doesn't need the cab pulled for servicing the turbo!!!!!!!! I won't buy a truck that I can't service myself. Lower more steady RPMs are the way to go for long service life, better emissions, heavy towing or even light load fuel economy. Heck, even the old 6.9L V8 has peak torque at only 1400 RPM. Ford would have to build a new transmission to match such an engine though. All this talk of trying to make a truck "feel" a certain way just makes me sick. I bet even the 6.4L has (or had) some real potential if ford marketing would only stay out of the way.

 

If ford adopted the 7.2 320hp 1000ft/lb monster stated earlier, the SD could come with built in factory 5th wheel hitch, and beefed up drivetrain, and could probably pull 30,000-40,000 lbs no problem.

Red lining at say 2500, it may not win every race, but that truck could be built to run smooth and steady down the highway boy.

2500rpm is plenty of room for downshifting and other "problems" with running on 4sp tranny's, It would be nice to see a 6sp with lockup though.

If they cant fit a transmission/ drivetrain cobo in there, put a gear up box between the engine and tranny (like i might for a 466), and make the tranny spin 1.4 times for every engine revolution. That will make the transmission see "1400rpm" instead of 1000. This will keep death tourque from destroying the SD tranny. This could also change the gear ratios so that cruising could be 1400-1600, to keep mpg up.

 

As for all the comments and people presenting the facts on the ford 6.4 being junk let me just go ahead and defend this engine for a moment. This engine is a great platform for power

426 hp on tuner alone no DPF no CAT and awesome mileage. has driven alot of miles with no DPF or kitty and not a problem no check engine light.

you want to get more MPG get rid of the kitty and DPF they suck the life out of these engines.

Next up all this talk about the 7.3 we want the 7.3 back. I want diesels to move forward not backward and most of the people wanting MPG and a 7.3 and power. heres a idea. go pickup a used 1994-2002 F-250 or F-350. spend the money on a vegistroke system and get it tuned a DIY intake a 5 inch exhaust bigger turbo. and well you may have spent 30000 dollars on all of this (truck included) but you now have more horsepower than a stock truck and you get about 0.15-0.30 cents a gallon.

the 6.0 is a bad motor. well I live up here in canada where it can get 100 degrees out in summer and -40 in the winter. and my dads truck a 04 6.0 has been through it all. and nothing has been replaced on it since we bought it. the oil still looks like honey.

and saying that dodge has had the same engine for the last so many years no they have had the same block not the same engine.... even saying they had the same block is a stretch I do remember there being a few 24 valve blocks that got a hairline crack in them. 12 valve no electronics 24 valve electronically controlled injection. 24 valve common rail. all very different injection setups and all very different ways needed to produce horsepower.

as much as I have seen in the past few years with these diesel engines when you buy a truck from the big three chevy 6.6 you have to accept a weak frame and weak IFS. dodge 5.9 cummins you have to accept one of the weakest auto transmissions and drivelines. ford 6.0 liter I have to accept putting in headstuds and gaskets IF I want to go over 400 HP.

The 6.7 liter if it exists for 2010. all I can say is we know really nothing
about it other than ford is making diesels in house now. I will finally be able to say my superduty is a Ford from bumper to bumper.

 

I don't see why everyone is getting all worked up about Ford building there own diesel. We have a 1986 L-8000 Tri- axle, and a 1991 L-8000 single axle dump truck that both have a Ford in line i believe 7.8 liter turbo charged. Both engines were built in Brazil. The 91 has 242,000 no engine problems, the 86 has 359,000 no major problems. In the single the motor is awesome 10sp and power for days it seems.In the Tri it's a little under powered but it does pretty well on fuel. We have an 85 L-9000 with a big cam cummins and it has 545'000 no major probs. The little inline ford is a great motor for the 33,000 and down trucks.The big trucks it's night and day differant.
But back on topic, i have a 03 250, 7.3 and i love it. If the diesel ford makes in house is as good as the ones in our dumpers sighn me up.

 

I`m saying 33,000 could be a 40,000 superduty rating with a little work.
Mabye instead of ford competing in the horsepower rating war with dodge and chev, they should go for a 40,000 lb towing capacity superduty that gets the same mileage as a regular 1 ton.

Who wouldnt buy that, it would appeal to everyone who knows a thing about mechanics. Theres even the distinc possibility that this hypothetical beast would get better fuel mileage than the 6.4.

Also, ford would corner another market, people now using 3-5 ton trucks for towing may be able to use the superduty and SAVE money , AND FUEL!!!

Farmers might be able to get rid of old grain trucks, and other similar trucks, and buy 1 superduty and trailers for hauling. Imagine the money that could be saved by a customer !

And at the end of the day, you can still take the kids for a ride to the store, or haul a camper.
*(or semi trailer )

 

This is of course based on my want of ford to use that 7.2 inline 6 common rail 320HP"2200 1000ft lbs engine described above.


Another thing, people are buying trucks for power right, so wouldnt the ability to pull a house behind you at cruising speed be more proof than a HP rating, right É

 

Agree, makes a lot of sense for the future.

 

an inline does not have more torque it just produces its torque at a lower rpm than a v8. as far as otr trucks having only inlines Detriot diesel made v8 and v6 for otr trucks for ages.

 

Ford offers two diesel options for the ranger in places like asia and europe, I think it makes complete sence to start marketing diesels as more than just a one size fits all as ford is doing right now with the SD powerstrokes.

 

I am sorry but I am not going to spend 50,000 - 60,000 dollars on a new truck to put a tune to it and remove the dpf just to have no warranty so I have to pay for anything that WILL go wrong with the motor. All of that just to get the MPG's out of a motor that they could make it get to begin with.

Ford needs to quit putting themselves in the HP war and start getting mpgs out of these diesels or they will not sell as many of them.

 

Thought Nissan was going to rebadge the Ram as their own, like Sterling does?

 

I would sooner spend 50-60 grand rebuilding an older truck, at least that way I know what I have when its done. A warranty is not worth as much as it used to be IMO.
