Volkswagen Memos Suggest Emissions Problem Was Known Earlier

Volkswagen internal memos and emails suggest that company executives pursued a strategy of delay and obfuscation with United States regulators after being confronted in early 2014 with evidence that VW diesel vehicles were emitting far more pollutants than allowed.The documents also raise the possibility that Martin Winterkorn, Volkswagen’s chief executive at the time, knew of possible emissions cheating by the company sooner than he has said.
