VW probe widens to Porsche and Audi
Volkswagen is facing fresh questions after US regulators yesterday widened accusations of emissions-test cheating against the German carmaker to include the luxury Porsche brand previously run by new ceo Matthias Mueller.
The US Environmental Protection Authority (EPA) claimed VW used devices to rig air-pollution tests in 3-litre diesel engines mostly found in Audis and Porsches - the company's biggest sources of profit. Europe's largest carmaker had previously admitted to installing cheat software on up to 11 million vehicles worldwide with smaller diesel engines. VW said on Monday "no software had been installed ... to alter emissions' characteristics in a forbidden manner" on the larger engines. It did not immediately respond to questions yesterday, saying it would only correspond in writing. The biggest business crisis in VW's 78-year history has wiped as much as a third off its stock market value, forced out long-time ceo Martin Winterkorn and rocked the car industry - a key employer and source of export income in Germany.
