The US has had a harder time in forcing the oil industry into supplying the low-sulphur refined deisel fuel needed for the newer common rail diesel engines. Currently the sulphur content in US Diesel is 500ppm. In 2006 15ppm Diesel will be available. There was a good Scientific American article about it (unfortunately they charge $8 for a back issue .pdf) a few years ago. A somewhat informative link is here.

I believe that Europe already has the better fuel, hence the greater prevalence of diesel engines. ISTR reading that the newer, low soot diesels required the better fuel.

Yeah, your trucking lobby dollars at work again. A few states have managed to passed clean diesel laws of their own, but the Federal laws aren't in effect yet. I thought they were due to be in effect in 2006, but they could have been pushed back again.

It's because of this sad state that VW didn't bring over the PDI version of their diesel engines in the MkIV Golf/Jetta/Passat lines. There was a lot of interest in it on vwvortex, but the PDI needs the clean diesel.
