EPA Steps Up Emissions Testing in Wake of VW Dieselgate Scandal
The U.S. Environmental Protection Agency announced it will introduce addition tests in an attempt to look for so-called defeat devices such as those used by Volkswagen and Audi in its four-cylinder diesel automobiles to cheat emissions tests.
The EPA “may test or require testing on any vehicle at a designated location, using driving cycles and conditions that may reasonably be expected to be encountered in normal operation and use, for the purposes of investigating a potential defeat device,” it said in a letter sent to vehicle manufacturers on Friday.
The new tests will start immediately. “Manufacturers should expect that this additional testing may add time to the confirmatory test process,” the agency said, although it would not disclose exactly what the new tests would be.
“We are not going to tell them what these tests are, and they don’t need to know,” said Chris Grundler, the agency’s director of the office of transportation and air quality, during a conference call on Friday.
