In the automotive world, seven degrees of separation does not apply. If you connect all the major players via their joint ventures, licensing agreements and percentage-stakes of ownership, the degrees of separation should be reduced to something more like two. Visualizing these connections is difficult, but thanks to someone with way too much time on his or her hands, we don't have to. The colorful automotive family tree to the right breaks down the large automotive parental groups and their various children. GM takes up the most space on the chart, dwarfing Toyota. The chart also demonstrates that the split of Chrysler from Daimler broke up a once gigantic tree branch that heavily weighed down the industry. While it doesn't delve into too much detail, it does provide a somewhat manageable outline. Click on the image to view the chart in high resolution. Thanks for the tip, Mike!
