FRANKFURT (Reuters) - Many of Volkswagen's managers and staff dealing with emissions problems in the engine-development department knew about "defeat devices" being developed, Germany's Sueddeutsche Zeitung newspaper said on Friday, citing results from VW's internal investigation.
A whistleblower, who was himself involved in the deception, alerted a senior manager outside the department who did not react, said the newspaper, which researched the matter together with regional broadcasters NDR and WDR.
A Volkswagen spokesman declined to comment on what he called "speculation", saying the investigation was continuing.
