Volkswagen AG is closing in on a deal to pay $4.3 billion in criminal and civil penalties to settle a U.S. probe into the rigging of diesel-powered cars to cheat emissions tests. The agreement, which VW said Tuesday will include a guilty plea, raises the cost of the scandal to more than $23 billion in the U.S. and Canada, blowing by the 18.2 billion euros the carmaker had set aside to resolve the disputes.
