The fact of the matter is that All big 3, own at least 10% shares of there rivials. Ford almost killed the upcoming RX-8, since Ford management didn't see a future in rotary engines. check out i think it, It was at walgreen mag section ( don't rememnber the mag)
In short Madza engineer argue w/ Ford management to contiune work on rotoary engines. Ford owns shares in the reatively new Daewoo.
The only thing i can is that Honda and Nissian are the only one left that don't "have joint ventures" with anyone.
Okay here is just an execept, but I don't consider it a joint venture, is when Honda Passport=Isuzi Rodeo, Honda Odessey= Isuzi Ossai , they just rebahged it.
What I think ford want to do is buy into every company and "steal/borrow" design/technological advances. They would also have the ability to choose
there board of directors, and therefore have inside info.
Here one example, of borrow technological advances. Honda VTEC engines, it can be found on all engines these days. Toyota VVT-I, Ford DoTECH, Nissian CVTC .......
