"Either they couldn't (possible, but unlikely). Or they did, and knew VW was cheating," he added. "If so, why didn't they say anything? Because they had their own shenanigans?"
In the wake of VW's emissions-fixing scandal, BMW's stock prices also plunged today after German magazine Auto Bild reported one of the carmaker's diesel vehicles emitted 11 times the European standards for NOx.
In a statement in response to the Auto Bild report, BMW said it "does not manipulate or rig any emissions tests."
The emissions scandal has also opened the door to numerous lawsuits, amid accusations that the extra pollution cost the lives of an unknown number of people. Yesterday, Vox.com estimated the amount of added NOx pollution from VW's U.S.-sold vehicles to be from 5,800 to 14,200 tons to the atmosphere per year, assuming the cars are driven the U.S. average.
Vox.com estimated the number of premature deaths from the additional NOx pollution to be from 5 to 27 per year in the U.S., and from 74 and 404 each year worldwide.
