As far as I understand the leaked picture:
- M side mirrors instead of M235i mirrors (color is up for debate: is it AW like the body color or is it the new Hockenheim Silver Metallic, or - who knows - some light grey as signature color for side mirrors of all M2 Competition cars ?);
- kidneys 'stretched' closer towards the headlights;
- surface below kidneys is now more vertical to allow front PDC mount + added: a crease line starting below the kidneys w(e)aving towards the headlights;
- a crease line above the fangs now runs through the tow hook flap (instead of above);
- front PDC (park distance control) (the dot located next to the tow hook cover);
- if no optical illusion (picture angle): the fangs angle seems pushed more inward towards the air curtains (longer horizontal fangs crease line);
- headlight washer nozzles still at the same spot (cover is visible if you look closely);
- air guidance intakes on the chin spoiler (1 out of 3 visible on the leaked picture).
Air guidance intakes on the chin spoiler of the BMW Vision Concept GT6 and BMW 3.0 CSL Hommage:
