Daimler has reportedthat its subsidiary, Mercedes-Benz, was asked by theUnited States Environmental Protection Agency (EPA) to reveal the emission levels of certaincar models. Daimler has said that the request for thisinformation was made in responseto a class-action lawsuit filed by the law firm Hagens Berman on February 18, 2016. The lawsuit was filed in the US District Court in New Jersey.
The class-action lawsuitstates thatMercedes-Benz misleadsprospective buyers with its BlueTEC vehicles by claimingthat they are'the world's cleanest and most advanced diesels'.

A Daimler spokesperson has said that the lawsuit is without merit butthe company is co-operating with the EPA's request for information. The spokesperson further addedthat all Mercedes-Benz cars comply with the rules and regulations of the land.
However, Daimler did add that under some circumstances, a system which treats exhaust fumes could function at a lower level of efficiency in order to prevent condensation from building up. This condensation can lead to corrosion and affect the efficiency of the exhaust system and the engine. The spokesman confirmendthat this is permissible and not illegal.
