Reports in the German media indicate that Porsche is being probed in the ongoing Volkswagen emissions cheating case.
The investigation commenced after it emerged that even Porsche had its cars installed with emissions cheating software that is capable of disguising its cars’ carbon dioxide emissions under test conditions. Further, reports also emerged that Germany’s Motor Transport Authority (KBA) is “examining software to see whether it could measure the angle of a car’s steering wheel.”
Earlier this year in summer, it has already been found that Audi vehicles’ were also equipped with the cheating device that lowered vehicles’ exhaust emissions under test conditions. According to findings, the technology that was used in Audis were capable of detecting when a car’s steering wheel is dormant and if it were, it was an indication that it was in lab-testing mode and hence it needs to lower its emissions output. If the wheel was turning in any direction more than 15 degrees, it means that the car wasn’t dormant, but was driving and hence it can return to elevated emissions output. Audi reportedly stopped using the software in May, and suspended several engineers.
In September 2015, the California regulator began using enhanced detection and screening procedures on all modern vehicles—diesel or gasoline—to find undisclosed devices that impact emissions. Volkswagen admitted that 11 million of its diesel cars had software that recognized when the car was undergoing official emissions testing.
The Department of Justice, on behalf of the Environmental Protection Agency, sued VW, Audi, and Porsche for violating EPA standards and the Clean Air Act. Volkswagen in January proposed a catalytic converter fix for up to 430,000 vehicles affected by the emissions scandal.
