It doesn't matter if Chrysler was to sell the SRT-8 at $15K while getting 30 mpg having in excess of 500hp, with the conventional models costing in the low teens, and it came with a guaranteed cure for cancer and many other diseases. The Mustang will never be dethroned in this class by the Challenger in sales. The Mustang has in excess of 40 years of momentum behind it. The Challenger is starting fresh. The thing we can hope for though is when the Challenger is in full production, is that the different models give the Mustang a beating.
