For more than 40 years, one inconspicuous building outside of Ann Arbor, Michigan has been making the air we breathe cleaner. It’s the home of The Environmental Protection Agency’s National Vehicle and Fuel Emissions Laboratory. No engine can be sold in America without its stamp of approval.

This week John McElroy gets an exclusive look behind the walls of the Lab as he talks with the EPA’s Chris Grundler about the work they do there, how it impacts the auto industry and the motorized products that we all buy.
