18. Dodge Challenger SRT Demon
If for any reason 707 HP from the Hellcat package is not enough and you want the ultimate modern muscle car and the most powerful street Hemi engine, the Demon package is for you. With standard fuel, it delivers an insane 808 HP. However, if you use the high-octane stuff, it will pump out almost 840 HP.
The rest of the Demon package is equally insane from a special transmission, suspension, and brakes to the widebody stance and exterior details. The acceleration from 0 to 60 is less than three seconds. Under full power, the Demon will accelerate with 1.8 G force, which is faster than being dropped off a cliff. The car can cover a quarter-mile sprint in less than 10 seconds straight from the dealer.
