WASHINGTON–The U.S. Environmental Protection Agency (EPA) is revising estimates for four 2014 BMW Mini Cooper vehicles to ensure consumers are given accurate fuel economy values.

The EPA performed a fuel economy audit on the BMW Mini Cooper and obtained values that differed from those BMW submitted to EPA for certification. With EPA oversight, BMW conducted new emissions and fuel economy testing, and EPA conducted its own testing at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan. As a result of this subsequent testing, EPA is requiring BMW to relabel four of its 2014 Mini Cooper models with lower fuel economy values.

“Fuel economy values matter to consumers and automakers,” said Christopher Grundler, director of EPA’s Office of Transportation and Air Quality. “To provide consumers with the most accurate, reliable and repeatable fuel economy values, we are continuing to strengthen our oversight to ensure fair competition among automakers.”

EPA’s National Vehicle and Fuel Emissions Laboratory conducts fuel economy testing on vehicles each year to ensure that their performance matches the mileage and emissions data automakers submit to EPA. These audits are part of the oversight program that helps ensure all carmakers are following the same procedures for calculating mileage estimates. The oversight program also helps the EPA verify that vehicles on the road meet national tailpipe emission standards to protect public health and the environment.
