Nine out of 10 new diesel cars exceed EU pollution limits, report finds

Road test reveals cars emit seven times the permitted level of exhaust emissions when tested in real-world conditions

Nine out of 10 new diesel cars break new EU pollution limits when tested on roads rather than test tracks, according to a new report.

On average, the cars emit seven times the permitted level of NOx gasses, with the worst car producing 22 times the legal limit. Models from every major motor manufacturer breached the limit when they were evaluated in real-world conditions.
