Maybe that's a good indication of the benefit of the N20, plus stop/start etc.
Oh, yes, I forgot about the F30's start/stop advantage, which they say adds 1 mpg to the ratings it gets.

And, yes, this is a good example of how much more you get from a four paired to a manual transmission than paired to an automatic.

Interesting too is that the mileage goes the other way when you pair the manual with the six. Down to 20 & 30.

This is also a pretty clear indication that we have the N20 here in the U.S. because it was a money saver for BMW. Four bangers with manuals are the norm in Europe and it was much easier for BMW to ship this new motor over here than R&D a new, smaller inline six for the U.S. market. Add that to the fact that Audi already was only offering a four in the A4 and Merc was also moving to a four banger in the C and it was the perfect storm.

However, all of that does not change the fact that, contrary to popular argument, BMW did not have no choice other than a four to meet CAFE requirements. If they had wanted to they could have done it with another inline six. But, as is clearly indicated, most U.S. consumers don't give a rat's ass.
