Clean Diesel Fraud

September 2015: EPA discovered Volkswagen installed “defeat devices” in 11 million diesel vehicles (2009-2015 TDI models) to cheat emissions tests—emitting 10-40x legal NOx limits while showing compliance during testing. #DieselGate exploded: $30B+ settlements, criminal charges, CEO resignation, and betrayal of “clean diesel” marketing. Volkswagen’s reputation crater; diesel passenger cars effectively died in US.

Fallout

The scandal expanded: Audi, Porsche diesels implicated; other manufacturers (FCA, Mercedes) faced scrutiny. TDI owners received buybacks ($5K-10K+ vehicle value) or fixes reducing performance. Hashtag sentiment: anger, betrayal, environmental hypocrisy. Diesel’s US death accelerated EV transition. By 2020, VW pivoted entirely to EVs (ID.4, ID. Buzz), attempting redemption through electrification.
