    @ John,

    Just to clarify, the previous (six cylinder) diesel version of the BMW 3 series was the 335d, not 328d. 328d is a new designation with the introduction of this model (even Europe doesn't have a 328d).

    I know because I have a 2010 335d. ;)

    @Loren: Entirely right, and thanks for pointing that out. I've edited the article accordingly. Brain fade while writing!

    if they could find a way to make use of the 80% wasted energy in the form of heat which is pertinent to all ICEs of any kind then i would probably give it a good looksie but otherwise, no thanks, electric trumps ICE as it currently stands.

    You completely missed the new 2015 Mazda6 diesel that will be here next year.

    @Steve Note that the title of the article says "2014". We'll cover the 2015 Mazda 6 diesel, assuming it arrives, when we do a similar roundup of 2015 models.

    Explain to me please, how this technology, which is neither new nor expensive, should be sold at a premium by Automakers? Shouldn't there be a shift away from gasoline ICEs to diesel or natural gas? And shouldn't those cars be more attractive to buy because of immediate savings, not those which can be realized in 3-5 years? Heck, with immediate fuel savings, one might turnover a car in 2 years which would benefit the automakers.

    I just think these grand old manufacturers are senile in their sales and marketing strategy, and is another reason I own a Tesla Model S.

    @David: The diesel engine itself is not new, but the complex and expensive aftertreatment (including urea injection) to enable diesels to meet current North American emissions standards is new--and quite expensive.

    Automakers say that a diesel engine is about 15 percent more expensive to manufacture than a gasoline engine of the same output, largely due to its having to be stronger to withstand higher compression ratios. Then there's the aftertreatment and associated plumbing that have to be built into the vehicles.

    THAT'S why diesel models are more expensive.

    I doubt these regulations matter on diesel generators do they..? They seem to always be dirty and pretty cheap, starting at around a thousand and putting out much more power than a gas generator…

    Besides aftertreatment (which gasoline engines also have...catalysts...although not as costly as the urea and particulate filters on diesels) they generally require larger & heavier components due to their high compression ratios, and more sophisticated fuel systems since power delivery isn't throttle controlled, rather fuel rate controlled. Materials and sophisticated components do cost something.
