how much horsepower does a challenger demon have
Well, in its press release, Dodge said nothing is a coincidence and everything means something in these Demon teasers, which sounds to us like an obvious wink at the Demon's power output. That 757 horsepower is 50 horsepower more than the 707-hp Challenger SRT Hellcat on which the Demon is based. Dodge has also done this sort of teasing before.
