Diesel pollution in 2016
The emissions of the new diesel cars are still high
While we thought that the Volkswagen affair would push the automobile manufactures to produce models more respectful of the environment, a report from the association Equax Index (EI) demonstrates that the 2016 diesel cars are still not respecting the emission limits, under the condition of real- world driving.
Besides, some tests have demonstrated that the diesel models of Renault (Megane 1,5L and Espace 1,6L) emit twelve times more NOx (nitrogen oxide) on the road as compared to an essay in a laboratory.
The diesel Mercedes Benz CLA 2.1 L produces eight to twelve times more, in real condition on the road, than the limit of the test carried out in laboratory. Whereas a Mazda 3 1,5L or a Hyundai Sante FE 2.2 L produce up to eight times more than the limit of NOx, in real conditions.
Ironically, the only model which respects the Euro VI norm on the road is the Tiguan of Volkswagen.
Other analyses have shown that 97 percent of the diesels launched since 2009, exceed the limit of the European regulation outside test zones. This questions the efficiency of laboratory tests required by European regulatory bodies.
Towards new modalities of compliance testing Euro VII
The European Commission is heading towards a new system of trials for the approvals of the new diesel models. For now, it is legal to sell the polluting models as soon as they manage to pass the laboratory tests.
Starting from September 2017 the diesel engines which produce more than twice the laboratory limit will be banned from the roads.
