Porsche Cars North America has stopped sales of the Cayenne diesel model owing to new emission scandal that surfaced. The SUV sales will be suspended until further notice.
The Environmental Protection Agency (EPA) found the emission cheat devices in Porsche and Audi vehicles that are powered by the 3.0-litre diesel engines. Cayennes made from 2014 to 2016 models come under this category.
Porsche say that this stop sale notice was made voluntarily and "in view of the unexpected U.S. EPA notice. We are working intensively to resolve this matter as soon as possible. Customers may continue to operate their vehicles normally."
The EPA said that more cheat devices were found in vehicles such as 2015 Porsche Cayenne, 2014 VW Touareg, 2016 Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5 models powered by the 3.0-liter diesel engines, developed by Audi.
EPA came to this conclusion after testing vehicles in real world conditions, beyond laboratory tests. Previously, only the 2.0-litre diesel engines were affected under the Diesel Gate scandal.
After the announcement was made by the EPA, only Porsche suspended sales of vehicles as of Tuesday. The EPA found around 10,000 vehicles with the 3.0-litre diesel engines that had the cheat software, which would show lower emissions while being tested in a lab.
