Nitrogen Oxides, one of the common toxic pollutants emitted by diesel-fueled cars are still being emitted in high amounts even by newer models, far more than the limit set, despite the issue with Volkswagen earlier on. The carmakers found to have diesel cars which high levels of NOx include Mercedes-Benz, Mazda, Hyundai, and Renault, and was discovered by a test done by Emissions Analytics, the data gathered by the said firm is utilized by the car makers in Europe.
The only new diesel car found to have met standards for NOx emissions is the Volkswagen Tiguan. Volkswagen previously came under fire due to cheating NOx emission tests in laboratories by using software, and it exposed the reality that Diesel-fueled cars have much higher NOx emissions in the real world than in laboratories.
Furthermore, since 2009, a mere 3% of the diesel cars launched were able to pass the standards set for NOx emissions. Pollution caused by the said gas is a huge problem, so much as to cause deaths of more than 23,000 people annually in the UK.
On Tuesday, a new research shed light on the problem of air pollution in the UK, that it is not one of primary concern, as government officials have higher regards for safety on the road and progress of the economy. Emission standards and regulations have been made rigid and starting September next year, diesel cars which emit twice more than the limit for NOx emissions would be pulled out from markets.
This particular road test is almost like the test EU is implementing, which found that the 2016 model of the Renault Megane and the Espace breached the limit for NOx emissions by up to 12 times more. Other cars which failed the test include the Mazda 3, Mercedes-Benz CLA, and the Hyundai Santa Fe, which had emission levels 6 to 8 times higher than acceptable levels.
Once the testing standards would be altered next year, from then on it would be illegal for cars with high NOx emissions to be sold.
