However, Hennessy is going to sell 500, 600, and 725 HP Challengers. http://www.musclecarblog.com/story-249-620_hp_hennessey_challenger_hits_the_streets_with_eleven_second_quarter_mile_force
I look at all the aftermarket hype on the Challenger and conclude that we will see a cult force of growing aftermarket upgrades unlike any new car since JC Whitney opened a catalog.
