Italian carmaker Fiat is breaking EU safe limits for nitrogen dioxide emissions with one of its models, a German environmental protection NGO said Tuesday.
Measurements by the German Environmental Aid Association showed the Fiat 500X 2.0 diesel four-by-four vehicle was putting out between 11 and 22 times the acceptable minimum values, the group said in Berlin.
Fiat-Chrysler declined to comment on the test results on Tuesday.
Last week, while stating that "its diesel engine applications comply with applicable emissions regulations," the carmaker announced a voluntary update of its Euro 6 diesel engines to adapt to tougher "real driving conditions" emission tests under EU consideration.
The NGO said its tests had been carried out on the appropriate equipment at the Bern University of Applied Sciences in Switzerland.
The German Environmental Aid Association has made similar claims against Opel, Mercedes and Renault vehicles in recent months. All the manufacturers said their vehicle emissions were within the limits.
