It's not official until it's official (BMW announces it publicly), but further confirming clues that the F32 coupe will be badged as the 4 Series Coupe comes from a list of a list of forthcoming miniature scale models that BMW AG has released internally in Germany,
according to BMW insider Scott26.
In addition to the new M6 models and 6 Series Gran Coupe, they identify the F34 3 Series Gran Turismo and the F32 "
4 Series" Coupe as the upcoming BMW miniatures to be released.
If true, with the F32 coupe badged as a 4 Series, expect the M version (F82) to be named the
M4 coupe, as per tradition for M model names. The only reason this doesn't happen is if the BMW board decides to break with BMW's naming convention and makes an exception in naming the upcoming F82 as the M3 coupe (instead of "M4").
