In the largest auto scandal settlement in U.S. history, a federal judge has approved a $14.7 billion settlement over the Volkswagen diesel emissions cheating scandal. The payouts include buybacks for impacted vehicles and cash compensation to U.S. car owners. Volkswagen has admitted to rigging some 11 million vehicles worldwide.
