In an utter disbelief, the Environmental Protection Agency (EPA) has done its test with 2012 BMW 3-Series to knock down the company’s claims of 328i’s MPG to 33 highway, 23 city for the automatic. The car’s rating for the model will stand for the moment as there is no possibility for BMW to petition an EPA retest.

Confirming this to an online media, the BMW claims that that the EPA has issued revised numbers for the eight-speed automatic-equipped F30 328i, with highway fuel economy taking a 3-mile-per-gallon hit to 33 mpg and the city number consistently dropping by a single digit to 23 mpg. For the first time when the 2012 3-Series made its debut, speculations were rife about the mileage. The BMW 3 – Series 2012 is powered by a 2.0-liter TwinPower turbocharged four-cylinder, ditching the inline six that formed the basis of the E90. By all calculations, 33 mpg is still the highly impressive and well out in front of the competition.

Tom Plucinsky, BMW spokesman, said that “Unfortunately, there is no provision in the EPA rules for a re-test this year. Therefore regardless of the results of our investigation, the new rating will stand for this model year.” Though the fuel efficiency hit is disappointing, even with the downgrade to 33-to-34 miles per gallon, the 3 Series’ fuel economy figures and performances are still class-leading. It still competes with the Acura TL and TSX, Audi A4, Cadillac CTS, Infiniti G, Lexus IS and Mercedes-Benz C-Class.
