Overview of the car brands and their connections

[1zippo1]

I'm writing my thesis about the automotive industry and I came by this IMO very cool overview of the major players in de sector. I thought some of you might be interested in this overview.



I knew about 99% of these connections but I was surprised to see that hyundai en DaimlerChrysler were so closly linked. Is this correct??

And I think the connection between BMW & DaimlerChrysler is a mistake.
