The EPA will be systemically re-testing all models of light-diesel vehicles on U.S. roads, reports Newsweek.
“Today we are putting vehicle manufacturers on notice” that there will be additional testing to look for defeat devices, Christopher Grundler, director of EPA's Office of Transportation & Air Quality told Newsweek.
“We aren’t going to tell them what these tests are, they don’t need to know. They only need to know we will be keeping their cars a little bit longer, and driving them a little bit more.”
The EPA says it has the proper expertise and equipment to detect the defeat device.
