From the depths of hell the all- new 2015 Hellcat Hemi Challenger is unveiled at the Brampton assembly plant in Ontario, Canada.  With a demons purr the new ’15 SRT Challenger is powered by a supercharged 6.2-liter Hellcat Hemi engine, and listening to it come alive in the video above is yet another treat for us.

Producing 707 hp and 650 pounds of torque, the most powerful  muscle car to come off the factory line to date. Trumping the Viper and the 2013 Mustang GT500, this is now the most lethal street-legal muscle car.

With the release of the new 2015, this is the first application of modern V-8 supercharger technology for SRT. Making history, the Challenger SRT comes standard with two key fobs -red and black. The black key fob limits the driver to a tamed down 500hp engine output. While the red key fob opens the gates of hell and unleashes the Hellcat at 707 horses of fury.

Delivering new design changes and performance enhancing technologies, consumers can expect to see the all-new SRT displaying a new cabin interior design, inspired by the 1971 Challenger.

Taking this beast to a new level of firey hell, the transmission has been upgraded to a 8HP90 gearbox from an 8HP70. This giving the ride the ability to handle the extra power and torque.

The new ’15 Challenger is also sporting a new front fascia and vertical-split grille, along with a larger front splitter and supercharger fender badges enhancing the aggressive stance. Continuing with the appearance changes, the ride is sporting a new power-bulge aluminum hood with a dedicated cold-air intake that will come standard in body color or offered in a Satin Black finish. The rear design gets a new split tail-lamp, fascia, and the diffuser, an all new design as well, along with a taller rear spoiler completing the Hellcat hellbound look.

The Dodge brand celebrating its 100th birthday in 2014, is moving the brand back to its performance foundation. The Challenger inadvertently becomes the flagship ride of the Chrysler brand, beating out the Viper in HP, and will be on showroom floors across the nation this August. What remains to be seen, with the Mustang and Camaro getting a little pumped up as well, will this be the muscle car of 2015 to be beat? SRT says, “bring it!”.
