Diesel models of Volkswagen‘s sports automaker Porsche have much higher emissions than is lawfully allowed, German weekly Der Spiegel reported, mentioning test results.
The publication asked German test institute TUV Nord to examine emission levels for the Porsche Cayenne V6 TDI, an SUV design, under regular driving conditions.
“Emissions in this test were higher than the limits for this kind of car,” the head of testing at TUV Nord Helge Schmidt said.
“With these values the automobile would not have been authorized by the authorities,” Schmidt said.
Porsche stated that it had received and studied the test results from Spiegel. “For us they are not understandable,” Porsche stated.
The automaker stated that emissions depend on numerous conditions such as engine load, speed and temperature.
