Berlin:
Scandal-hit Volkswagen has suspended officials from the research and development wing of its core brand VW, luxury division Audi and sports-car maker Porsche, news agency Reuters has reported citing sources.
Europe's biggest automaker has acknowledged installing software in diesel engines designed to hide their emissions of toxic gasses. Around 11 million cars of its group brands worldwide are affected by the diesel scandal, it has said.
Countries around the world have launched their own investigations after the company was caught cheating on tests in the United States.
The company's internal investigation is likely to focus on how far up the chain of command were executives who were responsible for the cheating, and how long were they aware of it.
