Thanks for the correction.
I was reading further in AutoWeek and they have another article regarding the Audi R10 TDI that won Sebring. It runs on special synthetic Shell diesel fuel derived from natural gas - not oil - using the same Fisher-Tropsch process that the Montana program is proposing (and used by Hitler to power his diesel tanks and heavy trucks in WWII). They allude to blending this type of synthetic diesel with the new lo-sulfer diesel and biodiesels that will begin appearing in the US in September. They also indicate that Audi/VW will have a system similar to Mercedes and will meet California's "toughest in the world" standards, although maybe not until 2008. I don't think diesel passenger cars are going away anytime soon.
