Former Audi CEO Rupert Stadler, on trial over charges related to Volkswagen Group's diesel scandal, blamed engineers for his failure to uncover widespread cheating on emissions tests.
Stadler, testifying for the first time, told a Munich court on Tuesday that engineers gave the management board at the VW Group's luxury-car unit insufficient information to detect the fraud.
The 57-year-old is the first of several high-ranking VW executives to go on trial in Germany over the diesel scandal, which has cost the company at least 32 billion euros ($39 billion). A separate trial is scheduled to start next month against former VW CEO Martin Winterkorn, 73, and other suspects in Brunswick in VW's home state of Lower Saxony.
Stadler’s testimony stuck close to the standard corporate defense that any engine manipulation was the fault of a group of rogue engineers.
He told the court that instead of coming clean, like their counterparts at VW after the cheating was uncovered in September 2015, leading Audi engineers still pursued "a salami tactic" to get around internal scrutiny.
He said that meant the engineers disclosed only bits and pieces, or slices, of information, rather than giving the full picture.This hindered his efforts to get to the bottom of the misconduct and caused damage for the company, he said.
Stadler is accused of failing to stop the sale of affected diesel cars in Europe even after U.S. authorities uncovered the engine-rigging to bypass emission tests. Aggravated fraud carries a sentence of between six months and 10 years under German law.
His defense lawyer, Thilo Pfordte, has lashed out at prosecutors in previous hearings, claiming they tried to force the former Audi chief to stand trial even as allegations against him are less severe than those leveled against the other suspects.
