Pollution test cheating software 'on more models than thought'

Software allowing six-cylinder Volkswagen diesel engines to cheat on pollution tests is on more models than was originally thought, US environmental regulators have said.

The Environmental Protection Agency (EPA) accused VW on November 2 of putting the software on about 10,000 Volkswagen and Audi vehicles with three-litre engines from the 2014 to 2016 model years.
