I'm doing the same thing. While I would love a diesel fusion/milan, it's probably not going to happen. They wouldn't use the 6 that's going in the f-150 as it would be much to heavy. They would probably use a 4 from europe, which is already available. Engine certification is a PITA, and it's cheaper for ford to use engines already in development for the US. Sucks, but that's the way it is. Cost down, profits up, and all that jazz.
