Well, this isn't correct, is it? Even for the NA market:
"There are three different engines available, including BMW’s Advanced Diesel in the 335d Sedan which achieves 36 mpg on the highway."
By my count, there are four engines available for the 3-Series in NA. Unless they purposefully cleave off the M3 as another car category altogether.
