From the rear PDC sensors, the solo G80 from the Nürburgring appears to be painted in Portimao Blue.
It also appears we can kind of get a glimpse of the rear bumper reflectors on both the G80 & G82.
They do appear to be the final design as they fit nicely into the contours on the sides of the rear bumper a la F87.
Interestingly, the G80 seen testing in Southern Europe with the G82 appears to be an older mule based on the mirror design and the rear reflector placement compared with the solo 'Ring G80 and
yesterday's spy shots.
Wheels seem to differ as well but that can also be due to specs that are yet to be determined.
