Whoa shit...
Pics according to Autobild, and according to CAR magazine, the coupe version of the 3 series will have it's own old-school kidney-style grille (as oppossed to the saloon's new version), and a 4.4L 425bhp V8.
My my... if the next M3 looks like the pics, then there is still hope for an aesthetic fight between it and the RS4!
