The redesigned 2012 BMW 328i, with its 240-hp, twin-turbocharged 2.0-liter inline-four cylinder and an eight-speed automatic transmission, gets a fuel-economy rating of 23/33 mpg city/highway, according to the EPA.
While that figure is respectable, it's lower that what was expected compared to the original EPA rating of 23/36 mpg, according to Autoblog.com.
The EPA revised the figures recently, knocking off 3 mpg from the 328i's highway figures. The city mileage number remains unchanged.
In a press release to Autoblog, BMW said it was "surprised" by the revisions. While the EPA is known for making small revisions, the 3 mpg downgrade is steep, and BMW says the figure is "abnormally low" in relation to its other vehicles like the recently discontinued 335d, which gets a 23/36 mpg rating with its inline-six diesel motor.
BMW can't have its 3 Series retested this year, so the EPA figure is sticking around. The 2012 BMW 3 Series went on sale in February with a starting price of $34,900, excluding an $895 destination fee.
