Its funny you said that.
A few months ago, there was a "release of info" from a person who had a "reliable source" that talked about that specifically.
Eventually, and sooner than later, the GT500 will be Ford's top gun. Big HP, everything. Almost what it is now. Ford knew that the ZL1 was coming out with at least 556hp so lets ask ourselves, why such a big jump. Well, that big of information now makes complete sense.
Now, this reliable source mentioned something along the lines that "...dont be surprised if they (ford) brings back the cobra/terminator." This car would represent a middle of the line performance mustang that will bridge the gap between the 5.0 and the GT500. Much like the GT500 was when Ford GT was in production.
Lets assume that this "new" model stang would be a supercharged 5.0 motor (much like the boss 302 5.0) making similar power to the ZL1.
I think that, in essence, is what ford is planning. A base 5.0, a track version that might stick around (boss 302), a middle the ground performer that will probably be more inline with the current ZL1 and then their top dog, the GT500.
Whatever car anyone of us has, these are awesome times! 600hp+ from the factory are a blessing.
Now, chevy needs to answer back and piss the stang boys off with a lighter, big HP camaro to get their attention.
