This statement, from the Obama administration's "New Path to Viability for GM & Chrysler" outlines the issue:
Industry financial analysts and industry experts are nearly unanimous in their views that, to be competitive in the decades to come, auto companies will need to transform their processes and products to improve efficiency, reduce costs, and offer higher quality, more fuel efficient fleet.
In other words, both companies need to get a whole lot greener if they want to get bailed out. Obama's administration is forcing a point that's long been clear to many, many people (excluding the Big 3, that is)--fuel efficiency is a necessity now, and will be even more so in the future auto market. So what does Obama have in mind for the future of the two failing car giants?
