German Design

I am looking at doing a tour of the more renowned design companies in Germany, such as BSH, Audi, BWM etc. I have found Munich to be loaded with these companies, but other areas such as Berlin, less so. Is this just a flaw in my research (which I expect it may be) or is there a reason for it? What are some of the bigger companies found around Germany (excluding Munich) and also Europe as a whole. Staying within ID/PD/Manufacturing ideally!

If you want to start in Munich you could work your way up
along Ulm, Pforzheim, Cologne and then into the Netherlands.

For German adresses work through the ID consultancies lists on

Munich is strong, but there are other as strong clusters with
different focal points.

Good Luck! (Viel Glück!)
