I just read a similar article in the Toronto Star this past week-end.
If this car flies (meaning goes into production), something is going to be sacrificed. Viper or Xfire is your guess. I personally think it will be the Viper but I could also envision that both could be replaced. Presumably, this would be 100% American home-made and as a "Corvette Fighter", in the words of the Chief Design Engineer, it would make more sense.
Price would come in much lower than the Viper but higher than the Xfire. I can only hope that it's not an automatic only. Worst nightmare!
