Car manufacturers

This is a rough diagram of which manufacturers produce which cars. Most of the details are from Cars! Cars! Cars!, with additional information and fact checking from the Wikipedia. Where a car and its manufacturer share a name the car name is omitted.

I did want to include some indication of the relative sizes of the companies, perhaps by market value, spurred by the news that Toyota is now worth more than GM and Ford together. However, I couldn't find a good source for this data.

Although I'm not a major automobile buff, if any major changes come into my peripheral vision I shall attempt to keep this chart up to date.

Update 28 Nov, 2005: I now use dotted lines to indicate partial ownership.

Update 15 Dec, 2005: I suspect that some of my ownership designations are inconsistent, due to my lack of knowledge. For example, I have shown Toyota as part owner of Fuji Heavy Industries, which makes Subaru. In contrast, I depict General Motors as part owner of Isuzu directly, because I don't know if it's actually owned indirectly through another company. Still, I don't think it detracts from the whole.

Update 28 May, 2006: Added Porsche's partial ownership of VW (as of late 2005).

Update 27 Nov, 2007: Split DaimlerChrysler. Moved partial ownership of Isuzu from GM to Toyota and Mitsubishi. Gave Aston Martin its independence.

Update 1 Jan, 2010: Added Fiat as part owner of Chrysler. Moved Jaguar and Land Rover from Ford ownership to Tata. Added Ford as partial owner of Aston Martin. Removed Suzuki from General Motors umbrella.

Update 4 Jun, 2011: Moved Volvo from Ford to Geely. Moved Saab from General Motors to Spyker.

Update 4 Nov, 2011: Latest diagram has moved.
