The front part look close to the f20 1er, with the same hood and similar headlights (the upper part its the same) with one light bigger than the other. Immagine a f20 light cutted on the bottom...
The kidney grills has the style of the 4er concept and 6er in my opinion, with the external border stretched to the lights.
The back has something that recall an f30, but it's hard to have a clear idea of the final car, the lights clearly wont be small as on the 1er.
Why they can't just use the front part of my E92?! I love it too much
