US Volkswagen chief knew problems in 2014

WASHINGTON D.C.: The US head of Volkswagen prepared to apologize to Congress on Thursday over the “deeply troubling” pollution scandal as it emerged he knew of a potential problem with vehicle emissions as early as spring 2014.

In testimony released ahead of his hearing with the House energy committee, Michael Horn offered a “sincere apology” for Volkswagen’s use of a software program “that served to defeat the regular emissions testing regime.”
