Study Finds Almost All New Diesels Are Dirty, Automakers Disagree

While it may appear as though the VW dieselgate scandal forced automakers to clean up their diesel vehicles, new testing reveals that most of them continue to emit more toxic NOx than permitted.

The Real Urban Emissions Initiative (TRUE) uses a beam of light to analyze the exhaust plume of a car, Popular Mechanics reports. The rating system has been developed from over 370,000 measurements taken in the United Kingdom, France, and other countries.

During TRUE tests, Euro 3, 4, and 5 diesel vehicles all returned “poor” ratings for NOx levels. Interestingly, almost all new diesel vehicles classified under Euro 6 emission standards received the same rating, meaning they emit more than 180 mg/km of NOx. The only vehicles to receive a more favourable “moderate” rating came from the BMW stable.

According to Greg Archer from Transport & Environment, TRUE testing reveals that the diesel industry has a long way to got before becoming clean.

“The TRUE rating exposes the legacy of Dieselgate – tens of millions of dirty diesels that are still on the roads producing the toxic smog we daily breathe. The rating highlights that nitrogen dioxide pollution, even from most new diesels, is well above those of gasoline cars, legal limits and manufacturers’ claims.”

However, the European Automobile Manufacturers’ Association (ACEA) says the results are misleading, as the newest Euro6d vehicles coming out for the 2019 model year were not tested.

“As all cars tested as part of this TRUE Initiative were pre-Euro 6d vehicles, the fact that they do not meet emissions requirements that only became mandatory after they were put on the market is not surprising,” ACEA secretary general Erik Jonnaer said.

    This is what happens when you try to “save the world” using technology suited to heavy goods transport in a consumer application. Saving the world by reducing the population.

      I’m all for a purge. I say that for one week we remove all of the warning labels and people and companies aren’t held responsible for others’ stupidity.

        But people buying diesels don’t care about environment, other people, driving experience, real service costs or even suitability of a diesel car for specific usage. All they care about is the fuel price. Many times they truly believe that people driving petrol cars are stupid “cause they have to pay more”.

        • Daniela Wolf

          our taxation for diesel cars is 6 times higher than a petrol car…..
          And u speak about saving money…..

            Oh well, sorry. I forgot that there is only one relevant country. Yours of course. Forgive me that I was foolishly thinking only about most of the European countries.

            So it’s true where you live, big whoop, can you speak for most other places? That’s like me saying poverty is fake because I live in a fortunate country.

            There u can read new tests on a daily basis that reveal thatemissions of petrol cars are way too high .^^

          • D’Arcy Surrette

            Interesting information.

          • ace_9

            The emissions of petrol cars might be high compared to regulations. But I seriously doubt they are even comparable with diesels. It is the question of better evil. Diesel cars are certainly much more harmful and that is why they should not be present in most of the personal cars. But many people are not even thinking about getting a petrol car. That is the actual problem. If people would not buy them, then the manufacturers would not sell so many of them, they could focus on making petrol cars even more efficient and clean and stop caring about diesels. But if half of customers are still stubborn pro-diesel fans, then manufacturers are practically forced to offer diesels if they want to sell as much as possible.

            Dude one statement:
            NOx kills some people ( no tests )

            CO2 will kill us all .

            What is ur choice?

          • ace_9

            Seriously? NOx kills some people and there are no tests to prove it? 😀

          • Daniela Wolf

            Get some.^^
            WHO states that NOx is not deadly ( over 1600 mg Nox per 100 km are needed to harm humans )

          • ace_9

            You are ridiculous… And your intro statements like “dude” or “get some” are so stupid I don’t bother to write anything more.

          • Daniela Wolf

            U played urself out,
            u can’t bring in a study to justify ur point and that’s why u surrender to me.^^

      The issue I have with that thought is, applying many of the ideas that diesel engines use, improved the fuel efficiency (and possibly emissions?) of non-diesel engines. The problem with diesel is that the fuel itself produces too many harmful emissions, so its not even “suited for heavy goods transport” either. Its just that it became the standard fuel for those purposes for other reasons (some of which are no longer valid, its just that it takes a lot to change something that is so ingrained in industries). I feel like hybrids with turbine engines as range extenders would be a more optimal approach. Run the trucks at lower speeds (to reduce the impact of aerodynamic drag) but use autonomous technology to be able to keep them running for the longer time it will take.

      • ace_9

        I find the trucks aerodynamics interesting. I’m commuting on a highway almost every day and the trucks are already quite slow, but I wonder why the trucks are still so boxy? Why not make the front of a truck more aerodynamic and at least cover the sides behind the cabin a bit better. Something on the rear of a trailer would also help a lot to reduce turbulences and it does not have to be very complicated. Even new trucks are rounded, but they are far from being aerodynamic. So I’m thinking there must be something much more important that forces the manufacturers to continue making the traditional boxy cabins. Or maybe the aerodynamics is not really so big of a problem…

          I think they’re more concerned about how much cargo they can haul in each load and less about fuel efficiency and aerodynamics

    This is what Americans have been saying for years and why Americans never really bought them.

    How many times did the egg-in-their-face Euros laugh and snarl at Americans for not buying ir driving diesels? Typical Euro trash (not all, just too many) were so mouthy and now it is being proved Americans were right after all. Oh, and a little Euro brand diesel emissions scandal to boot. https://uploads.disquscdn.com/images/afb03f83610d632a07041ba7cea0e10f2bcee5aa73633789f6142020ac8cb9ba.jpg

    HOW?

    TO SEE IF YOUR POSTS ARE ACTUALLY BEING SEEN BY OTHERS ON HERE, LOG OUT OF DISQUS, LOAD THE PAGE YOU POSTED A MESSAGE ON AND CHECK IF IT STILL APPEARS. YOU CANNOT SEE IF YOU POSTED AND ARE STILL LOGGED IN TO DISQUS (IT WILL LOOK LIKE YOUR POST IS ON THE SITE); YOU HAVE TO LOG OUT AND THEN RELOAD THE PAGE TO SEE.

    • Mr Mister

      Right, which is why there are posts from someone with the username “move on libtards” with them posting blatantly (to the point of outright idiocy) pro-Trump and anti-Tesla comments on most articles. You comments are probably being blocked for being too many words/long.

      • Basically the whole comment section under Tesla articles are from haters.

        • Daniela Wolf

          And u are really wondering urself about the Tesla hate?

    • Stigasawuswrecks

      So where’s the propaganda? I get get why people like you consider facts backed by evidence that proves your beliefs false propaganda Just say you don’t like being shown you’re wrong.

          Sorry, Michgo. Couldn’t resist.

  • Bash

    Well, diesel is diesel. And will always be diesel.

  • D’Arcy Surrette

    Obviously, the technology does not exist to lower diesel emissions. If the governments want lower emissions, they should fund the automobile manufacturers for the research. Don’t force legislation onto the manufacturers and expect immediate results. The research costs money.

  • ProtectOurHeritage

    Most studies can find whatever they like depending on how they skew the figures. Has the average person ever heard of The Real Urban Emissions Initiative (TRUE) or trust their findings?

  • nauticalone

    Not surprised by these findings. And i agree

  • Six_Tymes

    Hey Automakers, what no more “Clean Diesel” advertising? If Automakers Disagree, lets see them bring back their “Clean Diesel” advertising again. BUT, they wont, because its T.B.S.

  • Alfa Giulia QV

    Well damn. That’s not good and there is at least 15 million of them in Germany last I checked. They’re going to have their hands full dealing with that and outright banning them which would force people to buy petrol or hybrid cars may not go so well.

    Personally, diesels should have stayed in commercial vehicles and other heavy equipment.

  • WHO EVER THOUGHT DIESELS WERE CLEAN?

  • eye.surgeon

    I always get all my scientific emissions test results on diesels from advocacy groups dedicated to eliminating diesel.That way I know it’s unbiased. And let’s not forget it was the Green movement that forced automakers to push diesel in the first place.

  • ace_9

    You are of course right. I’m not saying that the current situation is better. I see the solution in making cars lighter, more aerodynamic, but using efficient petrol engines with reduced emissions. And diesel cars should be reduced to the people who really need them. I’m not saying that everybody has to switch to diesel. But for example many of my colleagues are making below 15000 km per year, they are single, but they still own and want bigger diesel cars and they are transporting just themselves and a lot of air in them…
