... there is no legitimate reason for a wholesale abandonment of the Zeta architecture. It is a product ready for release with all of its development money spent. It has been crtically acclaimed, and certainly sets a new standard for GM RWD.
I will concede that in its present form its shelf life may be shorter than it would have been due to outside factors, but to toss it aside before letting it prove itself in our market is pure stupidity. If CAFE and fuel prices and currency issues pinch it back in the coming years, so be it. But to invite a huge and obvious loss when the product itself is so strong makes no sense.
A pendulum swing back to all FWD all the time is unnecessary panic. The product mix needs to be there to legitimize and showcase the range of capability GM can bring to bear. A better choice would be to offer these cars in a decent array and trim the models back as the market requires. GM isn't ready to replace them with anything of value at this point, so simply from the perspective of gaining development time for projects such as Alpha, it makes good sense to bring the Zetas to market for at least one generation. Doing this allows GM to get some return on the investment in both real dollars and intangibles as opposed the the defeatist mentality of running scared back to the failed concept of trying to compete with also-ran FWDs exclusively.
GM needs to use the breadth of capability which only it has in this industry to set itself apart. Managed properly, GM can field the widest variety made by any single company worldwide. To restrict itself to only smaller FWD cars and a few sizes of light truck would be to squander its best assets. One would think that GM had learned not to put all of its eggs in one basket by now. That approach has never done anything but punish them in the marketplace.
