Porsche pulled into VW emissions scandal

US environmental regulators have leveled additional charges against Volkswagen, pulling the German automaker’s subsidiary Porsche into the global emissions-cheating scandal. 

The US Environmental Protection Agency (EPA) said on Monday that it is now looking at 3.0-liter V6 diesel engines in addition to engines on some mass-market models that were suspected to have been equipped with test-deceiving software, Reuters reported.

The 3.0-liter V6 diesel engines are used mostly in larger, more expensive models like the Porsche Cayenne sport utility vehicle.

On the road, emissions of the smog-causing pollutant nitrogen oxide on the affected high-end vehicles could be nine times higher than allowed, according to the EPA.

Volkswagen took issue with the EPA’s findings, saying that “no software has been installed” in its 3.0-liter V6 diesel engines “to alter emissions characteristics in a forbidden manner”. 

The V6 diesel was designed by VW’s Audi unit and widely used in premium models sold by the VW, Audi and Porsche brands in model years 2014 through 2016.

The EPA’s move pulls Porsche and Audi deeper into the scandal that has already engulfed the corporate parent Volkswagen AG and its mass-market VW brand, Reuters noted.
