BMW CEO Dr. Reithofer recently had this to say at a press conference:
That would suggest that the BMW M4 Gran Coupe is currently under development. The news is a bit surprising since previous rumors suggested that the new model wouldn't have an M version because of its tailgate and the disadvantages it would bring from a structural point of view.“The new BMW 4 Series Convertible came out in March. In June, following the Coupe and Convertible, the third model in the new 4 series will be launched: the Gran Coupe. And for those customers who enjoy an even sportier drive, the M version will be available in September. Two further new M models are the BMW M3 Sedan and the BMW M4 Coupe, both available as of June.”
