Since its founding, EPA has been at the forefront of developing clean automotive technology and designing programs to reduce and prevent air pollution. Vehicle, engine, and fuel testing is an important way for EPA to verify emission standards are met and ensure the benefits from our programs become a reality. Our state-of-the-art test facility provides a wide array of analytical testing and engineering services for EPA’s motor vehicle, heavy-duty engine, and nonroad engine programs to support the Agency’s regulatory goals.
