As a reminder, Challenger SRT Demon will officially have a promotion next week at the fair in New York, a car will be compared to the already known Challenger SRT Hellcatimati 91kg less weight while the other changes related to the management, suspension, brakes, exhaust system, 18 -inch wheels, aero body kit and interior. It remains a question how much power to dispose of this 6.2-liter V8 engine, which is located under the hood with large opening for air (the Challenger SRT Hellcat otherwise has 717KS).
