It's not maybe, it's a fact. Ford owns nothing of Cummins.
This rumor has been bantered around the tow vehicle/light duty diesel P.U. forums for years.
It has a lot to do with the fact that the Cummins 5.9 is such a good, reliable oil burner compared to the trouble prone 6.0 Ford Power Stroke.
Also, consider, why would Ford use an International/NavStar built diesel, if they owned some or part of Cummins?
.......
Cummin's 5.9 is going to be enlarged to a 6.7 liter to make up for emissions changes that will be bringing the H.P. and Torque numbers down on current diesels without displacement increases.
......
Dodge is planning to go with the 6 -speed Aisin Automatic as it is a match if not a better auto-tranny than the current 6-speed GM Allison. Dodge currently uses the in-house built 48RE Automatic for their Cummins powered Rams. It is a very reliable, and sturdy tranny, but lacks the extra gears of the Allison. The 48RE actually is patterned after the famous Mopar 727 Torqueflite automatic that was used in Hemi, and 440 cid hi-performance muscle cars back in the late 60's and early to mid 70's. The 48RE was first introduced in the 2004 1/2 Cummins powered Dodge Rams. It replaced the 47RE which was pretty good, but did have some problems. So Far the 48RE isn't having any reported problems that follow a major trend.
......
When Nissan goes with a diesel that's competitive with the U.S. big 3 offerings, they will definitely need a beefier automatic, and a much heavier rear-end too. If their current 5 speed Automatic can be beefed up to handle the monumental torque of competitive diesel torque, that would be great. I hope they don't go with a 1/2 measure, but invest R & D in a good heavy duty unit. I also hope that Nissan might go away from Dana rearends and go with American Axle that supplies heavy duty units to GM, and Dodge. I'm not sure about Ford's rear end venders.
If that upcoming diesel is Cummins, Navstar, Duramax, or a Hino....etc.., it will certainly be an interesting development. If Nissan goes with the Cummins, they will need to lengthen their engine compartment considerably as the Cummins is an inline six. The Powerstroke and Duramax are V8's. The Cummin's pistons and rods make the powerstroke and duramax's look pretty puny. Only the Cummins is rated for medium duty service as the powerstroke and duramax are not(light service rated diesels).
Ultra low sulfur diesel will be the norm and will be the main offering of diesel fuel in the U.S. by the time Nissan and Toyota jump into the light duty diesel p.u. market.
.....
Where Nissan and Toyota could really trump the Big 3, would be if they offered a smaller diesel that has H.P. in the 200+ h.p. range with torque in the 400+ ft/lbs. range. The mileage difference between that type/size diesel and a midsize gasser engine would be unique and incredibly popular in my opinion.
Never the less, if Nissan and Toyota were to jump in with diesels the size of the big 3, it will make for an interesting situation for "us" the consumers. Maybe it will even drive down the premium prices tacked onto diesel equipped p.u.'s.
