We recently reported that BMW was struggling to gain EPA approval for its range of diesel engines in the US. Even though "there [was] no indication that BMW's diesel models do not meet all requisite emission standards or that there [was] a defeat device in the vehicle," the EPA put the engines through extra scrutiny all because of Volkswagen's Dieselgate scandal. According to Reuters, after a series of extensive tests, BMW has gained approval for its range of 2017 diesel models. BMW says that a measly 4% of its US sales are diesel models.

This may not sound like huge news, but BMW has now done something that other automakers are striving for, getting EPA approval for diesels in the US. Volkswagen has yet to receive approval for its 2016 model diesels, and has not asked the EPA to approve 2017 models according to EPA boss Chris Grundler. Mercedes-Benz is another manufacturer lacking EPA approval for diesel models. Daimler Mercedes has stated that the EPA and the California Air Resources Board were also conducting inquiries and that it could face "delays in obtaining regulatory approvals necessary to introduce new diesel models."
