Automakers will have a new set of EPA guidelines for conducting fuel-economy tests, the agency announced Monday. The move is in response to some automakers — Ford and Hyundai/Kia — that have had to lower fuel-economy ratings on their cars during the past several years because of testing errors.
These guidelines cover vehicle preparation for the fuel-economy testing such as tire wear levels and breaking in a new car beforehand. They also cover the impact of aerodynamic drag and tire rolling resistance on a car’s fuel economy.
“Without question, [the] industry is paying more attention — and that’s a good thing,” Chris Grundler, EPA’s director of the Office of Transportation and Air Quality, told the Detroit News.
