- BMW has agreed to lower its fuel economy ratings for four 2014 Mini Cooper models after testing by the U.S. Environmental Protection Agency.
- The affected vehicles are the 2014 Mini Cooper and Mini Cooper S three-door models equipped with both manual and semi-automatic transmissions.
- The EPA found that the combined city/highway ratings were lower by 1 mpg than the figures submitted by BMW.
The EPA performed the tests at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan, and found that the combined city/highway ratings were lower by 1 mpg than the figures submitted by BMW for the 2014 Mini Cooper and Mini Cooper S three-door models equipped with both manual and semi-automatic transmissions.
As a result, BMW will lower the combined fuel economy for the 2014 Mini Cooper with manual transmission from 34 mpg to 33 mpg, and Mini Cooper semi-automatic from 33 mpg to 32 mpg. The 2014 Mini Cooper S with the manual transmission will drop from 29 mpg to 28 mpg, and the S model with the semi-auto tranny will be reduced from 31 mpg to 30 mpg.
On the highway, the manual-transmission Mini Cooper is being reduced from 42 mpg to 40 mpg, and the semi-auto version goes from 40 mpg to 39 mpg, while the Mini Cooper S manual will drop from 38 mpg to 34 mpg and the semi-auto model is being reduced from 38 mpg to 35 mpg.
City fuel economy is also being adjusted. The 2014 Mini Cooper equipped with the manual transmission will be reduced from 30 mpg to 29 mpg, and from 29 mpg to 28 mpg with the semi-automatic trans. The Mini Cooper S manual goes from 25 mpg to 24 mpg and the semi-automatic Cooper S will drop from 27 mpg to 26 mpg.
"Fuel economy values matter to consumers and automakers," said Christopher Grundler, director of EPA?s Office of Transportation and Air Quality in a statement. "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."
The reason for the discrepancy, according to the EPA, is that the Mini Cooper vehicles were "found to have road-loads (i.e. aerodynamic drag, tire rolling resistance, and driveline friction) which exceeded EPA audit criteria when compared to the values originally reported by BMW at the time of certification."
As previously reported by Edmunds, earlier this month Mercedes-Benz reduced the fuel economy ratings on its 2013 and 2014 C300 4Matic sedans following a similar EPA audit. In that case, the partial zero-emissions vehicle received a new rating of 19 mpg in city driving and 28 mpg on the highway, reflecting a drop of 1 mpg for each rating.
Edmunds says: EPA audits help ensure that consumers have the most accurate information possible to help inform vehicle purchase decisions.
