Everyone is watching with bated breath as General Motors teeters on the brink of bankruptcy, wondering if Chrysler's 'surgical' run through the courts isn't a practice session for GM's own. The latest victims of GM's preparations for a smaller, lighter future appear to be the 2010 Chevrolet Impala SS and 2010 Cobalt SS Sedan. Neither will be built.

The information, revealed through GM's online ordering guide and caught by the fans at GM Inside News, shows no order codes for either the Impala SS or Cobalt SS Sedan for the 2010 model year. The Cobalt SS Coupe is still available, however.

With all that's going on both in the public eye and behind the scenes at GM, it's not really a surprise, but on the flip side, GM hasn't announced the deaths of either car yet. Still, it's likely a business decision based on order and sales figures, so it's hard to argue that GM is abandoning its fans - if they were there buying the cars, they'd probably still be available.

But it'll be hard not to miss the Cobalt SS Sedan - it was one of the best cars in GM's lineup, and one of the best turbo-four four-doors sold in America.
