Diesel fuel in the US, presently, can have sulfer content as high as 600 ppp if I recall correctly. Later this year by law it must be reduced to 6 ppm ( ULSD ). This and the NOX problem keep diesels from being marketed nationwide so only a niche player like VW makes an effort. The conversion from the higher sulfur fuel to ULSD will not be overnight IMO so 2008 is realistic to see diesels from everywhere start to flood into this market.

Honda announced yesterday a diesel Odyssey option along with an Acura MDX option for 2009. They are the same vehicle - only different. The Odyssey is really a key player since it is often the primary vehicle of the woman of the house and if it's a positive experience - BLAM - diesels are off and running.

Hybrid diesels seem like a wonderful option to 'multiply' the inherent benefit of diesel over traditional gassers. Using biofuel in a diesel feeds my inner hippie as well . Now a PHDV ( Plugin Hybrid Diesel Vehicle ) powered by B100 is Nirvanna.
