When BMW rolled out the M4 at the 2014 New York Auto Show, it represented the culmination of the 3 Series splitting into two distinct models. The four-door sedan version and all of its derivatives still carried the 3 Series name, but the sportier two-door variant was renamed the the 4 Series. The latter then gave birth to the M4 performance coupe, and three years after the first M4 burst into the scene and into our welcoming arms, BMW has finally announced an update to the coupe that has turned into one BMW’s most popular models.
