Ford Diesel's are ace !!
They are shooting themselves in the foot not introducing them here. At the moment VW has that section of the market covered, and I would say probably 1 out 3 VW's I see is a TD.
If Ford stuffed a Duratorq into a Focus they would sell, I'm sure of that. Plenty of people, especially now, are looking at cutting gas costs.
As for the quiet, no smoke/smell, from it. I've heard some rattley diesels back in the UK in my time, but never experienced one which was a 'smog-machine' like how people seem to depict them here. A 1.8l or 2.0l diesel is nothing like the beasts you have on the aging construction dump trucks you see pushing out plumes of smoke.
