EPA Revises Fuel Economy of BMW 328i Automatic, Lowers to 33 MPG Highway

BMW has confirmed to us that EPA will revise its fuel economy estimates for the 2012 328i automatic, with the official rating dropping from 24/36 mpg city/highway to 23/33 mpg—a 1-mpg difference in the city, and 3-mpg difference on the highway. Since the EPA’s rules currently don’t allow for retests, the revised rating will remain in place for the 2012 model year.

BMW says 328i models equipped with the eight-speed automatic transmission are the only models to receive a revised estimate, with the six-speed-manual-equipped version retaining its 23/34-mpg rating. BMW is investigating the reason behind the discrepancy, but regardless of the automaker’s findings, the EPA’s estimates will remain for the 2012 model year. The government’s fuel economy website currently doesn’t show the change, however BMW’s consumer page has been updated to reflect the revised numbers.

A BMW spokesperson told us that the EPA doesn’t test every car, and manufacturers must instead conduct their own tests following the EPA’s test cycle and submit figures each year. Sometimes, the EPA will validate those figures by repeating the test cycle itself. In this case, the EPA requested a 328i automatic for testing, and came up with different numbers.

We’ve been impressed with the performance from the 2012 BMW 328i’s new turbocharged four-cylinder thus far, and the promise of better fuel economy was a have-your-cake-and-eat-it-too kind of proposition. Now, we suppose you just get slightly less cake.
