I like how the rear diffuser is more pronounced than the tiny one on the F30. This one looks more like like the F20 M sport or the M Coupé diffuser.
The color seems a nice Valencia Orange-like color, with a more red hue in it. They'll probably use the same approach as they did on the M6 series, (sakhir Coupé and blue cabrio). This would translate in EBII as leading color for the F30 and this red for the F32 M Sport versions.
