A quick update: My A200 AMG line build is June 2020, with delivery early July. The build sheet shows it has multi-link axle. So, my guess is the 200 is going to torsion bar in the new July builds (based on the July 2020 brochure), and they removed reference to axle type in the December 2019 build, April 2020 version of the brochure, to avoid confusion during the transition.

Movement in the interior also triggers visual and acoustic warnings. The theft notification and parking damage detection function of Mercedes me alerts you by app in such circumstances.
