I just happened to scan the TV past PBS and caught the back end of Motorweek. They were reviewing the '07 E320 Bluetec. (hope I have the number correct)
They had nothing but good to say (they always say almost exlusively good things about the cars they review, leading me to believe they get paid by the car manufacturers to "advertise" their models). The thing that struck me is that while he acknowledged that it was a diesel, and touted it as an environmentally friendly alternative, along the lines of hybrids and the like, he mainly referred to it as a "Bluetec". I know this is the name being used for these new diesels and that it refers to some new clean technology, but it made me wonder if Mercedes is trying to avoid the use of the word "diesel" and thereby cut down on the negative stereotypes associated with the word.
