Executives for Volkswagen’s U.S. operations told lawmakers during a hearing on the company’s deceptive emission systems, that he’s confident the 500,000 so-called “clean diesel” vehicles secretly set up to cheat on emissions tests can be fixed with little disruption for owners. Michael Horn, CEO of Volkswagen’s U.S. operations, told the Oversight & Investigations Subcommittee of the House Energy & Commerce Committee on Thursday that while the carmaker previously said it could fix the issue by the end of 2016, it would likely take much longer. “The repairs will take five to 10 hours,” Horn said.
