Fuel cap door is still rectangular instead of circular.
Interesting that the C-pillar is camouflaged: is BMW M toying with the Hofmeister kink or considering the idea to affix a BMW logo (as on the BMW 3.0 CSL and 3.0 CS and CSL Hommage) ?
Recently the X2 also got this feature as a change for the sake of change (
"For true distinction, the BMW emblem has been repositioned next to the Hofmeister kink on the C pillar. Just another case of breaking the rules.").
Just remember that it is scheduled to go into production in December 2022. Still a long road ahead to a final version.
