This is the M-performance package you can order on top of the M-Sport.
Carbon diffuser lip front W/WO color decals. Quite a few F31 here in Norway with that option
First time I have seen it on a F34 thougt. I got mine in January 2014 and the M-performance wasnt ready yet.
Also a slight tuned up engine if you want. For exmpl 320d(328d in US) from 184 hp to 200 HP
