VW cheated on U.S. pollution tests for 'clean diesels'

Volkswagen called them “clean diesels,” branding them as the fun-to-drive alternatives to hybrids as it dominated the U.S. market for the engine technology.

Turns out the increasingly eco-conscious buyers of the sporty German cars have been unwittingly pumping smog into the air — because of software VW installed to cheat on U.S. emissions tests.

The world’s largest automaker has admitted selling 482,000 such diesels since 2009, California and U.S. regulators announced Friday. The scandal could cost the company billions of dollars in fines and lawsuit judgments and threatens to stunt the development of all diesel vehicles.

VW’s software trick allows the cars to emit up to 40 times the legally allowed amount of nitrogen oxide, environmental officials said.

Additionally it could face a fine of about $18 billion, or $37,500 per car, federal environmental officials said.
