I would see what Corning has to offer. They make (or will be making) particulate filters at their facilities in Erwin, N.Y. VW selected Corning to make particulate filters for their diesels. This article talks about that. And they have been making these sort of things (with ceramics) for a long time.

If I am not mistaken, all modern railroad "diesel" locomotives are "hybrid" as are such ocean liners as the QE2. Why shouldn't they be used in automobiles or other passenger vehicles?
