I think right now they have some good products on hand.
Volt is controversial as it was almost/is given freedom from taxation or some subsidy or something like that, though I am not sure what it was and Toyota opposed it.
The new Daewoo Lacetti i.e. new Optra i.e. new Nubira has made it to Korean market. Just launched with 1.6 114bhp motor.

So these two cars have sufficient strength to avoid bankruptcy.
Moreover the Camro just made it and if the success of retro sytled Mustang is anything to go by, then Camro will sell well.
This is very close, but now GM has sufficient weapons on hand to fight.
