Result: The systems also functioned well in continuous operation. Up to 80 percent emission reduction is possible, according to ADAC. But according to ADAC, their effect at lower temperatures is not enough. In summer temperatures, the systems would have managed to lower the nitrogen oxide emissions below the now established Limit of 270 milligrams per kilometer to press. If it getting cooler outsideHowever, the systems hold the meanwhile set by the federal government limits for such retrofit solutions, however still not one, said the ADAC Württemberg in March in Stuttgart. And: fuel consumption and CO2 emissions rose partly strong. This was the result of the ADAC endurance test in detail:
