oh..sorry..i was talking about the regular GT...the GT500 will likely be faster, but with ford cancelling the GT (40), the GT500 is now their flagship performance car...and compared to the SRT10 viper, or the new Z06, the GT500 is nothing...also, the GT500 is going to be VERY expensive from what i have read...and the challenger still has the possibility of a 6.4: "392 hemi" in the future, which very well could have the ability to handle the GT500...

and for what it is worth, like the rest of the fords fast vehicles, the GT500 is a forced induction car, as ford cant make a competitive vehicle without it...
