Audi A8 and Fiat 500X emit more than 12 times the official limit.

Diesel vehicles are still being favored in Europe for their high efficiency and good fuel consumption ratings, but a new study reveals almost all modern diesel cars exceed official pollution limits.

A few days ago it was announced Volkswagen, Opel, Audi, Mercedes, and Porsche will have to recall a total of 630,000 diesel cars in Germany due to a problem with the diesel emissions management software. Now, Emissions Analytics (EA) publishes new data that shows 97 percent of all new diesels on the market emit more toxic nitrogen oxide (NOx) pollution in real environment than the official limits allow. The study covers more than 250 models in standardized road conditions.

Shockingly, EA says only one of 201 Euro 5 diesels tested, a Skoda Octavia TDI, did not exceed the limit and just seven of 62 Euro 6 models are meeting the standards. What’s even more interesting is that most of the vehicles that did not exceed the limits were Volkswagens, while nearly a quarter of the tested cars produced at least six times more NOx than the limit. An Audi A8 and a Fiat 500X were registered to emit more than 12 times the official limit.

Tests were performed on the same route in south-west London using the same drivers, at the same time of the day with the same load in the trunk.

Experts from EA comment that these results show clean diesel cars can be produced but virtually all manufacturers are failing to do so.

“There is a growing worry about air pollution, but while some car manufacturers have been more proactive, others have done only the minimum,” Nick Molden, the CEO of EA, explains. “The point is diesels can be clean.”
