Former VW boss Winterkorn investigated for fraud
German prosecutors launched an investigation on Monday into former Volkswagen boss Martin Winterkorn over the rigging of vehicle emissions tests, as the carmaker suspended three top engineers in an attempt to tackle the crisis.
Two German newspapers said on Sunday Volkswagen's own staff and one of its suppliers had warned years ago about the illegal use of so-called "defeat devices" to detect when a car was being tested and alter the running of its diesel engine to conceal their emissions of toxic nitrogen oxides.
Environmental campaign group Transport & Environment published new data on Monday showing that some new Mercedes, BMW and Peugeot cars use 50 percent more fuel than laboratory tests show, saying this was evidence of a wider industry problem.
"The Volkswagen scandal was just the tip of the iceberg," said Greg Archer, clean vehicles manager at T&E, adding the gap between lab tests and real-world performance cost a typical driver 450 euros per year.
