I wish I could believe that there will be a horsepower war. If there is, GM and Ford will be fighting it. Chrysler's typical response since the 80s to a superior car is to say "Well, yeah, theirs is fast, but fast isn't everything." And I don't really suspect that Fiat is going to be motivated to get into this, especially since they're dropping the Challenger anyway. As I've said elsewhere, my impression of Fiat is that they want to be known for European sports cars instead of American muscle.
