Dodge has dubbed the 2015 Challenger SRT Hellcat as "the most powerful muscle car ever," after releasing its official engine output figures.

The automaker previously said that the supercharged 6.2-liter Hemi Hellcat engine of the 2015 Challenger SRT is capable of producing over 608 PS, but Dodge says the vehicle can deliver more power.   

Equipped with the same engine, the 2015 Challenger SRT Hellcat can generate 717 PS with 880 Nm of torque, making it the most powerful Challenger ever.

Dodge has not release the full specification of the vehicle. The automaker said that the 2015 Challenger SRT Hellcat will come standard with two key fobs: red and black. The red key fob will be the only one that can unleash the full 717 Ppotential of the Hellcat engine, while the black key fob delivers a restricted output of 507 PS.
