So I saw pics of the car without camo just now, someone who works at BMW showed them to me. They just received one at their development center. Essentially, front headlights are the same as the 2 series with a vent integrated into the bottom corners, as we have seen in some of the renders. Honestly kind of disappointed, as I was told the lights would be completely different, but it looks good nevertheless. Laser lights are more than likely coming as an option.
Front bumper looks wayyyy more elegant than the spy pics from China. Bottom side vents stick out very far and make the front end look very aggressive. The grill doesn't stick out as far as we have seen; was more of a relaxed shape rather than a cookie cut shape.
The side skirts are body colored and have an interesting shape behind the doors that points upwards and attaches to the rear quarter. Looks good and also interesting. Kind of hard to explain, but it was a relief seeing it body colored. It seems kind of like a piece that will eventually be an M performance part. Can't say I've seen an M car with a side skirt design like this before though.
Carbon buckets inside.
Updated with new Information:
-Carbon roof has what looks like the traditional 1x1 weave pattern seen on the M3/4
-Rear bumper is pretty much dead on with the picture that has the front and rear bumper next to each other posted below
-This specific car has full black leather in the interior (seats included) and apparently the large screens of the iD8 don't look out of place
