M fans need wonder no more; the BMW Concept M4 has just been revealed at the 2013 Pebble Beach Concours d’Elegance taking place in Monterey, California this week. Though still a concept, the car is an almost perfect representation of BMW’s successor to the M3 Coupe, the new M4 (F32) , which we’re expecting to see debut at the 2014 Detroit Auto Show in January.
