Dodge Challenger SRT Demon
If for any reason 707 HP from the Hellcat package is not enough for you and you want the ultimate modern muscle car, then the Demon package is just your thing. With standard fuel, it will deliver an insane 808 HP. But if you use high-octane stuff, it will pump out close to 840 HP (via Top Speed).

The rest of the Demon package is equally insane, from the particular transmission, suspension, and brake to the wide-body stance and exterior details. The acceleration from 0 to 60 is less than three seconds, and the Demon will accelerate with 1.8 G force under full power. The car can cover a quarter-mile sprint in less than 10 seconds straight from the box. If the reports are accurate and Chrysler is considering discontinuing the Hemi engine lineup, Charger fans should buy these now.
