In this case, the diesel emissions cheating affected almost 5 million cars sold by the Volkswagen group in Europe and the United States, prosecutors said.
Both the Audi- and Volkswagen-developed engines were engineered to limit emissions during laboratory testing, but work in a normal non-compliant state when being driven on the road. As a result of the administrative order imposing the fine, "the active regulatory offense proceedings conducted by the Munich II public prosecutor against Audi AG will be finally terminated".
The massive fine prompted Audi to cut key financial performance indicators and parent automaker VW also said the fine will affect its earnings. Specifically, it concerned V6 and V8 diesel engines manufactured by Audi and installed in Audi, Volkswagen and Porsche brands, and Audi vehicles equipped with EA 189 and EA 288 engine made by Volkswagen.
Earlier this month, Volkswagen broke the contract of Audi Chief Executive Rupert Stadler, who is now being investigated over his alleged involvement in the diesel cheating.
The Wolfsburg-based group's 2018 earnings suffered another one-billion-euro blow in June when it agreed to pay a similar fine levied by Brunswick prosecutors over its own-brand vehicles. By accepting the fine, Audi admitted responsibility for its actions in producing vehicles that did not meet regulatory requirements. The case covered some 4.9 million Audi cars sold in Europe, the US and elsewhere between 2004 and 20018.
Authorities in Germany, the company's home market, issued the penalty as the company's chief executive at the time the so-called dieselgate scandal broke remains in prison, pending the findings of an investigation into the extent of his personal involvement.
