Volkswagen's emissions-cheating engine software was actually developed by Audi in the late 1990s, according to a new report.

So it’s Audi’s fault, huh?

According to Reuters, a new report from German newspaper Handelsblatt says Volkswagen’s emissions-cheating defeat device software was actually developed by Audi in 1999. But despite the software’s development, it wasn't used at that time. Instead, Volkswagen waited six years to actually use this technology, when the company was unable to reduce its nitrogen oxide emissions below legal limits.

Of course, this software came under huge fire recently, as Volkswagen Group engineers fitted these defeat devices to more than 11 million diesel-powered cars globally to improve emissions stats. Reuters says both Volkswagen and Audi declined to comment on this latest report regarding the 1999 development.
