This article is light on details. What's radical about contracting the production of various models to other manufacturers and selling them with your badge?
I think the only difference will come if the car-built-to-spec can change manufacturer but not name/model badge. The Saturn sedan build in, say, China in 2010 is the same card as the one build in, say, India in 2014. Same parts, same marketing. The end-users won't know the change and it won't make a difference.
If/when this occurs, it'll be a BIG change. It will give Saturn Mark II leverage over its suppliers, although it'll test the design tolerances a bit.
