9 Oct 2015 – <\/em>Mercedes-Benz, Honda, Mazda and Mitsubishi have joined the growing list of manufacturers whose diesel cars are known to emit significantly more pollution on the road than in regulatory tests, according to data obtained by the Guardian.<\/p>\n

In more realistic on-road tests, some Honda models emitted six times the regulatory limit of NOx pollution while some unnamed 4×4 models had 20 times the NOx limit coming out of their exhaust pipes.<\/p>\n

\u201cThe issue is a systemic one\u201d across the industry, said Nick Molden, whose company Emissions Analytics tested the cars. The Guardian revealed last week that diesel cars from Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and Jeep<\/a> all pumped out significantly more NOx in more realistic driving conditions. NOx pollution is at illegal levels in many parts of the UK and is believed to have caused many thousands of premature deaths and billions of pounds in health costs.<\/p>\n

All the diesel cars passed the EU\u2019s official lab-based regulatory test (called NEDC<\/a>), but the test has failed to cut air pollution as governments intended because carmakers designed vehicles that perform better in the lab than on the road. There is no evidence of illegal activity, such as the \u201cdefeat devices\u201d used by Volkswagen<\/a>.<\/p>\n

The new data is from Emissions Analytics<\/a>\u2019 on-the-road testing programme, which is carefully controlled and closely matches the real-world test the European commission wants to introduce. The company tested both Euro 6 models, the newest and strictest standard, and earlier Euro 5 models. Data showed that:<\/p>\n
