Stanford Professors Sue Volkswagen

Two Stanford professors filed a class action lawsuit in federal court Friday, alleging that the automaker intentionally manipulated its vehicles’ emissions systems by installing so-called defeat devices designed to evade mandatory emissions testing. The suit also raises suspicions about a Volkswagen lab in the Bay Area and its possible connection to a scandal that has left some skeptical about the company’s ability to regain public trust. Robert Handa and Scott Budman report.
