The Volkswagen emissions-test cheating scandal has enveloped a wide array of Porsche and Audi six-cylinder diesel vehicles.
As reported by the BBC, Matthias Mueller has been appointed as the new chief executive after Martin Winterkom resigned.
Regulators accuse the carmaker of using the same software, which changes engine performance during emissions testing with six-cylinder engines as it has admitted using in about 11 million four-cylinder diesels worldwide.
Audi and Porsche are VW-owned brands. The new infractions add an additional 10,000 luxury vehicles to the 482,000 VWs and Audis already cited by the EPA.
