The Spanish Ministry for Industry has analyzed the nitrogen oxides emission levels of 16 diesel models. In contrast to usual laboratory tests, the Ministry’s tests have been conducted on the road. The Ministry has detected significant differences: the on-the-road tests have yielded much higher NOx emission values. For this reason, from now on the homologation of a new vehicle in Spain will have to undergo both the laboratory and the on-the-road tests.
