EPA to Road Test Cars

News

(NBC) The Environmental Protection Agency is toughening its stance on emissions tests, after Volkswagen fooled regulators and violated standards.

Today, the EPA told automakers it’ll begin road tests of all new and used vehicle models to examine their emissions claims.

In a letter to manufacturers, the agency says it’ll no longer rely exclusively on lab tests to validate emissions performance.

It also plans to begin testing all light vehicle models already on the road in the U.S. to check for violations similar to Volkswagen’s.

Volkswagen has admitted to using software in diesel cars that evades emissions tests and acknowledged the problem affects eleven million vehicles worldwide.
