Until now, the EPA’s investigation into NOx emissions has centered around Volkswagen’s four-cylinder diesel engines equipped in the Jetta, Golf, Golf/Jetta SportWagen, Beetle Coupe/Convertible, Passat and Audi A3. The EPA is now investigating the larger 3.0-liter diesel, used by Volkswagen, Audi, and Porsche, to see if it is compliant or affected by the same “defeat device”, says David Shepardson of the Detroit News.

The larger diesel mill is used in the Touareg, Audi A6/A7/A8/Q7, and Porsche Cayenne.

More as we have it.

    11 million VW diesels are said to contain the ‘fraud bug’. VW sets apart 7 billion to remedy this calamity (and I don’t mean Jane). CEO Winterkorn is expected to step down…

    Oops, that’s already old news. Sorry. Anyone at VW considering the noble art of Harakiri?

    Congratulations VW, you’ve done more damage to the reputation of diesels in the US than Oldsmobile ever could.

    As someone on TTAC 1st mentioned yesterday, now we know why Mazda and ze rest of ze Japanese haven’t brought zeee diesel to U.S. & world markets in significant quantity.

      Heh.. yeah, I’ll make fun of Engrish all day long but I would *never* expect Japanese to be dumb enough to think:

      “Hmm.. need kreenah kah. Ret’s use srudge instead gas!”

      In most of the markets where the Japanese carmakers have a big market share, there isn’t that large tax differential between diesel and gasoline, there’s not so much incentive for them to emphasize diesel in their light vehicles.

      Also, both Toyota and Mazda have been doing some interesting work in Atkinson cycle style engines that get the thermal efficiency of gasoline fueled engines closer to that of a diesel than they ever have been before, so the incentive to go diesel is just not there.

      Diesels were regulated to death in the US on purpose but VWoA sales were 25% diesel (and I imagine a high percentage in Europe and China as well) so they decided to buck the system.

        “Diesels were regulated to death in the US on purpose”

        That “purpose” being that several major North American cities have geographical features that turn them into smog havens. Europe, despite being fairly progressive on many fronts, doesn’t seem to worry about ground-level smog, likely because Paris and Berlin aren’t subject to the fishbowl effect that Toronto or Los Angeles are.

          More so to the purpose that the European economies were devastated by the triple whammies of World War I, World War II, and post-war socialism such that the luxury of using more oil to choke less was unaffordable.

          Well France is trying to get rid of diesel vehicles now. Maybe they finally got sick of the levels of smog in Paris. Last time I was there, it was terrible. It was worse than Nairobi.

          always loved the fact the upper air current allowed us chicagoans to have our pollution blown to indiana and the east….

          as for the vw issue…i wish now i owned one. it would save me the trouble of monkeying with the pollution controls myself.

          as far as these cities with constricted geos…the fault is still in their city planning. they were responsible for their ridiculous growth and haphazard urban design and sprawl.

          trying to find public transportation in los angeles is like finding a waterhole.
          their freeways system is more the result of a child scribbling on a paper and then naming the lines as 10/405/90/110/91/5/105/605/170/134/710/ etc, etc, etc.

          this is l a county freeways alone!!!

            “the fault is still in their city planning”

            I can’t really dispute that, but cities grow fastest in flat terrain, and that means valleys. It’s only natural that cities should be disproportionately located in inversion zones.

          Toronto? Fishbowl? Where are those mountains that you speak of?

            Ah yes, the majestic and rugged mountain ranges of Ontario.

            “Toronto? Fishbowl? Where are those mountains that you speak of?”

            On the south side of the lake, you have the Niagara Escarpment, on the north, the Oak Ridges Moraine.

            The result, along with the thermal effects of Lake Ontario, create a handly little bubble along the Lake Ontario shore. Toronto gets the worst of it, but the rest of the horseshoe suffers as well.

            It’s because it was actually filmed in Vancouver. Every city in North America has a majestic mountain range in the background.

    “EPA Expands Emissions Investigation”

    No kidding! I think it should be obvious at this point that they will expand investigations to all diesel cars and trucks, and then to gasoline-powered cars and trucks.

    Who knows, this may actually convince some Republican reps to increase the EPA’s budget so they can do their own testing instead of trusting manufacturers.

    In related news, toxic air contaminants are down significantly in CA, thanks to EPA and CARB measures.

    I think at this point VW has gotten over the denial stage, and that it is not likely that the V6 diesels are affected.

    I don’t think this announcement is any more significant than Europe, Korea, et al, also announcing they will be testing more cars.

    This is good to see. After this is over I hope they turn some of this energy towards U.S. companies who manufacture in China and are really destroying our environment. Go EPA!

      Never happen.

      The common denominator in all “global warming” or “climate change” pacts I’ve ever seen or heard about, is that China and India are exempt.

      They’ll have to become appreciative enough of life over there to decide to do something about the pollution themselves.

        High populations need a certain level of employment, and employment creates pollution/waste.

          Hell so do we! Do you know what’s happening in major cities right now? Half of Chicago is a combat zone and our taxes keep going up to support the non-producers. The people need jobs! Use this momentum to do that. Today a few little Volkswagens. Tomorrow the big fish!

        It hasn’t been about the environment for decades. In 1970 when the rivers were afire and the sky was brown, absolutely. But those problems are long since addressed. The environmental movement today is just a PR cover to advance centralized government partnership and co-ownership of industry. And increasingly, of private citizen.

        There’s no need for American fascists to be concerned with Chinese and Indian pollution because the Westphalian principle of sovereign states, at least when those sovereign states have nuclear arsenals, reserves Chinese and Indian oppression to the Chinese and Indian governments. Respectively.

    I’ll be surprised if this ends without another major manufacturer or two found to be doing similar things. Given all the issues inherent in making clean diesel work, I’d be shocked if competitive analysis had not uncovered this years ago.

    I wonder if this will spread to boat engines? Mine had a Mercury TDI 3 litre V6 which is of course a marinised VW engine with claims of Tier 3 emissions compliance?

    Is there more than one diesel 3.0L V6? Because my Audi A4 has it, as does Q5, Passat and so the other two diesel powered Porsches. Just saying, it’s going to be ugly.
