It’s official: the Dodge Challenger SRT Hellcat is the most powerful production muscle car ever—and even more powerful than the Viper supercar, with 707 horsepower and 650 pound-feet of torque on tap.

The massive power output dwarfs even the previous ludicrous power title-holder, the 2013 Ford Mustang Shelby GT500, which rates 662 horses.

Generating its power from a 6.2-liter supercharged HEMI V-8, the Challenger SRT Hellcat won’t always be a complete handful to drive, however, thanks to a dual key fob system. The black fob limits the car’s output to 500 horsepower; opt for the red key fob, and you’ll get the full 707. We hear the potent powerplant may also make its way into the 2015 Charger.

A TorqueFlite eight-speed transmission, uprated suspension and classic 1971 Challenger-inspired interior design are also part of the Hellcat package.

The first examples should reach the market in the third quarter of 2014. You can listen to it rev below.
