If Toyota were putting a diesel in their trucks, why would they put a Cummins in when they have a full line of reputable Hino diesels at their disposal.
Ecodiesel is another example.
From what I understand, the Hino isn't currently designed to meet USA diesel standards, whereas it meets European standards. There was some question about cost and reliability to "retrofit" the engine to meet our standards.
I tend to think that Toyota would rather create an "in house" diesel rather than purchase a diesel from an outside supplier. Toyota generally likes to design its own products.
I think rumors about a Cummins in a Toyota are just rumors. I would be more likely to believe that ***IF*** Toyota offers a diesel Tundra, they will design their own engine. That being said, I don't have much faith that Toyota wants to design a heavy duty Tundra. I think they are happy producing 100K +/- Tundras a year in their current facility in Texas.
