BMW has issued out a statement that its 2012 328i automatic now has a rated highway fuel rating of 33-mpg as opposed to the originally announced 36-mpg.
The EPA reserves the right to validate the fuel economy figures that automakers submit through their own testing and reporting. Most of the time, the discrepancy is negligible – maybe a 1-mpg difference – but this time the EPA fuel economy figures has the new 3-Series automatic at 3-mpg (highway) less than BMW’s reported figures. City mileage also drops one tick to 23 mpg.
Of course this comes as a shock to BMW (surprise, surprise) and the German automaker is currently working to determine how it was possible. Unfortunately for them, the EPA doesn’t allow for re-testing this year, so BMW has done their due diligence in updating all of its 2012 3-Series automatic information to reflect the 33-mpg highway rating.
Even though it’s quite the hit to its numbers, the BMW 3-Series’ 33-mpg highway rating still bests all its rivals within the segment.
Those who opt for the six-speed manual will see fuel economy unchanged at 23/34.
