Hexagon is very prominent in precision manufacturing through their dimensional measurement robots (CMM Coordinate Measurement Machine) and other metrology software/hardware. This is most likely why they were chosen by BMW, as I imagine they already have a working relationship together, although the EU aspect could have contributed as well.

I wonder if this is a newly acquired subsidiary producing these robots (they've been doing a lot of acquisitions recently), or if these have been in development in-house for a while.
