Several Volkswagen engineers have admitted to cheating on carbon dioxide emissions data.
According to German publication Bild, the engineers say they were forced to falsify data because goals set by former Chief Executive Martin Winterkorn were very difficult to achieve.
The paper says VW engineers messed with tire pressure and mixed diesel with regular motor oil to make VW vehicles use less fuel. It claims that the deception began in 2013 and carried on until the Spring of this year.
“Employees have indicated in an internal investigation that there were irregularities in ascertaining fuel consumption data. How this happened is subject to ongoing proceedings,” a Volkswagen spokesman said.
The names of engineers involved in the Volkswagen scandals have not been released. It is believed that between 10-20 people were involved in the cheating scandal.
German officials are investigating the case and recently raided the company’s headquarters.
