In a wave of trouble, VW may drop CEO Martin Winterkorn in the vehicle emissions test cheating scandal reported Reuters on September 22. Winterkorn, the head of Volkswagen AG, will be replaced after the beleaguered German automaker was found to have falsified emission tests in the United States. This could affect some 11 million cars worldwide. The Tagesspiegel newspaper quoted sources who said Volkswagen's supervisory board would decide Friday on whether to replace Winterkorn with Matthias Mueller, who heads the company's Porsche sports car business.Volkswagon may drop VW CEO Martin Winterkorn in emissions test cheating scandal | Examiner.com
