"This car is not for everybody," Dodge brand head Tim Kuniskis said. "You do a car like this not to be subtle. You do a car like this to send a message to the rest of the industry on who you are, what you are and what you're all about."
For 2015, Dodge will offer the Challenger SRT in two versions, one with its traditional 6.4-liter Hemi -- which has received an output boost to 485 hp and 475 pounds-feet of torque from 470 hp and 470 pounds-feet of torque -- and the top-end version with the Hellcat. Either engine can be combined with a six-speed manual or eight-speed automatic transmission.
The Hellcat-powered Challenger will come with two key fobs: a black one that automatically limits the engine's output to 500 hp and a red one that unlocks the engine's full power.
A valet mode, which requires a programmable code to unlock, limits the Challenger SRT engine's output to 4,000 rpm.
The Hellcat engine achieves peak power at 6,000 rpm. Its supercharger was developed with the help of IHI Turbo, which also supplies Mercedes-Benz's AMG performance division, Chrysler executives said.
Dodge also is introducing electronic drive modes on the 2015 Challenger SRT. The system uses electronic switches through the coupe's Uconnect infotainment system to control horsepower, shift speeds, steering, traction and suspension.
