    Vauxhall Insignia worst polluter in UK

    http://news.sky.com/story/1682956/ca...ts-out-on-road



    All diesel cars tested by the Government after the Volkswagen emissions scandal exceed laboratory pollution limits in real-world conditions, a study says.

    A report by the Department for Transport on nitrogen oxide levels revealed that none of the 37 top-selling diesel vehicles met the legal level of 180mg/km when observed out on the road.

    But a spokesman for motor industry body the Society of Motor Manufacturers and Traders said the difference between results from laboratory tests and those performed in the real world are "well known".

    Cars that met Euro 5 standards, which could be sold up to September last year, were all "substantially higher" in real-world conditions than the measurements recorded in the laboratory, according to the research.

    The worst performer was the Vauxhall Insignia, which emitted more than 1,800 mg/km.

    Even the best performer, the Citroen C4, was found to emit around three times the legal laboratory level.

    Real-world emissions tests will be introduced next year, although diesel cars will at first be allowed to pollute more than double the current legal level because of their limited ability to reduce real-world emissions in the short term.

    Cars that meet the current Euro 6 standards have to meet 80 mg/km NOx limits in laboratory tests, but in real-world driving for 90 minutes on normal roads the average level recorded was six times higher.

    The Peugeot 3008 was found to perform the worst, at around 13 times higher.

    The £1m investigation found no evidence of car manufacturers other than Volkswagen fitting devices to cheat emissions tests.

    But the study did reveal the widespread use of systems to prevent engine damage, which can also lead to higher emissions in the real-world when the temperature is lower than during the approved laboratory test.

    VW admitted last September that 482,000 of its diesel vehicles in the US were fitted with defeat device software to switch engines to a cleaner mode when they were being tested for emissions.

    The German-based firm said some 11 million vehicles were affected worldwide - including almost 1.2 million in the UK.

    Transport Secretary Patrick McLoughlin said: "Our tests published today have not detected evidence of manipulation of emissions lab tests as used by the VW Group by any other car manufacturer."

    He added: "The UK has been leading in Europe in pushing for real-world emissions tests which will address this problem.

    "Real-world tests will be introduced next year to reduce harmful emissions, improve air quality and give consumers confidence in the performance of their cars.

    "Following the Volkswagen emissions scandal, the whole of the automotive industry must work hard to restore public trust by being transparent about the systems they employ and advancing plans for introducing cleaner engine technology."

    Transport Minister Robert Goodwill insisted the manufacturers "have not done anything illegal" by using engine management systems which cut emissions outside of the laboratory.

    On the real-world emissions observed, he said: "What's been disappointing is the levels of non-compliance have been higher than we'd expected."

    Mr Goodwill continued: "It's a bit like, you can pass your driving test on the day that you're being very careful but then in the real world it's slightly different.

    "That's the difficulty that we face."

    So.......if nobody can meet the standards, then isn't there a problem with the standards?

    Is it possible that VW created the situation with its cheat? Meaning the car mags were gushing over their seamless, fun power. The other companies that weren't willing to cheat so blatantly were forced to keep up and make their cars only compliant at very limited parameters, otherwise highly polluting. Probably not, but it couldn't help having VW being the dominant maker in the EU....

    But it does sound like the standards are pie in the sky....

    Here is the full Conclusion of the Report.

    Seems many are already tryin' to spin this away from Ford and onto whoever is handy.

    Which is basically everybody else but VAG and largely BMW.

    The issue with this (and really many other test) is that your mileage will vary, this is something that is really well understood. When you test something then those results only apply to the conditions in that test, you also can't make car companies liable if consumers drive in an unreasonable fashion. Though having one party willing to cheat and have an unfair advantage does push others to cheat, its like doping in sports. Everyone starts to do it because someone starts winning a lot and doesn't get caught.

    The problem with the old/current EU test is that it doesn't represent any sort of normal real-world driving - it's carried out at a temperature between 20-30 degrees C (68-88 F) despite the average European temperature being 0-5 C (32-41 F) and the cycle involves driving like Hoke Colburn which almost no-one does. We have the absurd situation that most cars/brands show improved fuel consumption from Euro 5 to Euro 6, but owners are finding that real-world fuel consumption is worse under Euro 6, up to 10% in some cases.

    The other problem with the EU test is the obsession among EU governments to drive down CO2, at the expense of other pollutants - until Euro 5b (2010 model year) there was no limit for cars on particulate matters which allowed and encouraged diesel domination due to their inherently better fuel consumption and since NOx limits were introduced in Euro 3 (2000 model year) they've always been higher for diesel cars than petrol/gasoline ones.

    The EU emission regulations are worded quite differently to the EPA in the US, as well as higher limits there's more scope for loophole exploitation - that's why the illegal cheat software in VAG cars in USA is just a devious loophole exploitation in Europe.

    The issue in USA caused a wider examination of diesel emissions in Europe which has shown that other brands use loopholes which would either be legal, just, in the USA or more likely they only sell petrol/gasoline in the USA - it has also brought the EU test itself under scrutinity and is now shown to be totally inadequate in measuring real-world emissions.

    It's the wider examinations of real-world emissions that has shown in each case that VW Group cars aren't the worst, indeed often among the best (or least bad, really) given that there's a much wider range of brands selling diesel cars in Europe than in USA.

    I'm not trying to defend VW for their actions in USA, they're indefensible, just to highlight that Ford, Opel/Vauxhall, BMW, Mercedes-Benz, Nissan, etc are just as bad.
