GM is planning to bring diesel Saturns and Caddies to the U.S. market in 2010. (A Caddie that gets decent mileage? Who’d have guessed?) They join Nissan, Honda, DaimlerChrysler, and of course Volkswagen in planning to market clean diesels that will meet the new 2008 regulations on NOx and particulate emissions from diesel vehicles.

Missing from this list of diesel adopters is Toyota, which is saying that clean diesels "… would end up being more expensive than gasoline-electric hybrids," a market segment which it dominates.
