Wide range of cars emit more pollution in realistic driving tests, data shows

Diesel cars made by Renault, Nissan, Hyundai, Citroen, Fiat and Volvo among others emitted far more NOx in more rigorous tests, research shows

New diesel cars from Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and other manufacturers have been found to emit substantially higher levels of pollution when tested in more realistic driving conditions, according to new data seen by the Guardian.

Research compiled by Adac, Europe’s largest motoring organisation, shows that some of the diesel cars it examined released over 10 times more NOx than revealed by existing EU tests, using an alternative standard due to be introduced later this decade.

Adac put the diesel cars through the EU’s existing lab-based regulatory test (NEDC) and then compared the results with a second, UN-developed test (WLTC) which, while still lab-based, is longer and is believed to better represent real driving conditions. The WLTC is currently due to be introduced by the EU in 2017.
