WASHINGTON - The U.S. Environmental Protection Agency (EPA) today announced that Hyundai Motor America and Kia Motors America will lower their fuel economy (mpg) estimates for the majority of their model year 2012 and 2013 models after EPA testing found discrepancies between agency results and data submitted by the company.

The auto companies have submitted to the EPA a plan for cars currently on dealer lots to be re-labeled with new window stickers reflecting the corrected mileage estimates. The mileage on most vehicle labels will be reduced by one to two mpg, and the largest adjustment will be six mpg highway for the Kia Soul.

“Consumers rely on the window sticker to help make informed choices about the cars they buy,’ said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “EPA’s investigation will help protect consumers and ensure a level playing field among automakers.”

At its National Vehicle and Fuel Emission Laboratory (NVFEL) in Ann Arbor, Mich., EPA routinely tests vehicles – 150 to 200 a year, or about 15 percent of the possible vehicle configurations – to ensure that their performance matches the mileage and emissions data required to be submitted to EPA by automakers.

This auditing helps to ensure that vehicles on the road meet tailpipe emission standards to protect public health and the environment and that all carmakers follow the same procedures for calculating mileage estimates. EPA conducts both random and targeted audits, based on factors such as consumer complaints.

EPA had received a number of consumer complaints about Hyundai mileage estimates. Through the agency’s ongoing audit program, staff experts at EPA’s NVFEL observed discrepancies between results from EPA testing of a MY2012 Hyundai Elantra and information provided to EPA by Hyundai.

The agency expanded its investigation into data for other Hyundai and Kia vehicles, leading to today’s announcement.

EPA’s audit testing occasionally uncovers individual vehicles whose label values are incorrect and requires that the manufacturer re-label the vehicle. This has happened twice since 2000. This is the first time where a large number of vehicles from the same manufacturer have deviated so significantly.
EPA and DOE are updating their joint fuel economy site, www.fueleconomy.gov, to reflect the Hyundai and Kia corrected numbers.
