EPA says Volkswagen cheated a 2nd time on pollution tests
The US government says Volkswagen cheated a second time on emissions tests, programming about 10,000 cars with larger diesel engines to emit fewer pollutants during testing than in real-world driving.
The German automaker installed software designed to defeat the tests on VW, Porsche and Audi vehicles from the 2014 to 2016 model years with six-cylinder diesel engines, according to the Environmental Protection Agency and California Air Resources Board. While on the road the cars give off up to nine times more nitrogen oxide pollution than allowed by EPA standards, the agency said.
The cheating was discovered by EPA and CARB tests performed after VW acknowledged in September that it rigged emissions tests for four-cylinder diesel engines on 11 million cars worldwide, including almost 500,000 in the US
