Rear overhang seems definitely longer.
Front looks more rounded and balanced.
The arch form of the window line less bent than the earlier shots.

A BMW 5 series size and not 3 series.
Same tricks in effect like MX, this time vice versa.
(MX 2012 protoype was longer and more elegant with a softer roofline compared to what we have today).
