WASHINGTON (July 15, 2014) — The Environmental Protection Agency (EPA) wants to put auto makers' mileage claims to the test.
An EPA proposal would require auto makers to road test vehicles to verify mileage claims posted on window sticker prices, The Wall Street Journal reported, citing EPA officials.
The move follows the recent restatement of EPA ratings on several cars and light trucks by Hyundai, Kia and Ford.
It's part of a broader effort by the agency to more carefully scrutinize mpg figures published by auto makers.
The difference between a driver's actual mileage and what a vehicle is rated is among the most frequent consumer complaints and questions posed to the agency.
“Some auto makers already do this, but we are establishing a regulatory requirement for all auto makers,” Chris Grundler, director of the EPA's Office of Transportation and Air Quality, told The Journal.
The proposal also would make it difficult for auto makers to manipulate lab results to deliver higher mileage claims, the newspaper said.
