Shed no tears over General Motors' (NYSE:GM) decision to unload its stake in Fuji Heavy Industries. GM's alliance with the maker of Subaru brand vehicles never amounted to much, and the American automotive giant certainly can use the cash from the deal. GM needs to get focused, and getting there could mean that even more sales are in the offing.

General Motors disclosed on Wednesday that it will sell its 20.1% position in Fuji Industries in two segments. Toyota (NYSE:TM) will purchase 8.7% of Fuji from GM for $314 million, while the remaining 11.4% will be sold into Fuji's share-buyback plan and on the open market, if necessary. All told, the U.S. car and truck manufacturer should raise about $735 million from unloading its stake. Sadly, that's about half of what it paid for Fuji about five years ago.

While losing 50% on an investment in just five years is never something to be celebrated, it seems unlikely that General Motors' interest in Fuji would ever have been particularly productive. The major product of GM's collaboration with Subaru was the Saab 9-2X, which never became a huge seller. General Motors delivered only 96 of the cars in September, down 69.6% from the 316 it delivered in September 2004.

And let's face it: When first- and second-quarter losses come in at $1.1 billion and $286 million, respectively, it's time to consider selling some unproductive investments. It would be nice to think that GM will plow the proceeds from the equity sale into developing vehicles that are more attractive to consumers, but unfortunately, it may have to use the cash to quell a more immediate problem. The automaker's main supplier, Delphi (NYSE:DPH), is contemplating bankruptcy and is asking General Motors for $6 billion in bailout aid, according to Bloomberg.

Granted, GM's sale may aid its competitor Toyota by giving it access to Fuji's superior battery technology, which in turn could help Toyota strengthen its hold on the hybrid segment. But GM doesn't even compete in that market, so it can't be that concerned.

In the end, General Motors' unloading of its Fuji stake is a positive for the company. GM seems to understand that although grand global alliances are fine when times are good, what it needs right now is a serious retrenchment.
