Challenger Hellcat from Dodge is the most powerful production muscle car ever

The Challenger SRT Hellcat is the most powerful production muscle car ever—and even more powerful than the Viper supercar. The Challenger Hellcat should reach the market later this year.

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.
