5. Dodge Challenger SRT Demon
If 707 HP from the Hellcat package is not enough and you want the ultimate modern muscle car and the most powerful street Hemi engine they ever made, choose the Demon package. With standard fuel, it will deliver 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 the special transmission, suspension, and brake to the widebody stance and exterior details. The acceleration times from 0 to 60 is less than three seconds. And under full power, the Demon will accelerate with a 1.8 G force. Amazingly, this car capable of covering a quarter-mile sprint in less than 10 seconds straight from the box.
