The quickest, fastest, and most powerful sedan in the world is American.
It was only a matter of time before the mighty 6.2-liter, supercharged V-8 engine found in the Dodge Challenger SRT Hellcat found its way into its four-door sibling. The most powerful V-8 engine Chrysler has ever made has been stuffed into the new Dodge Charger SRT Hellcat, making it the quickest, fastest, and most powerful sedan in the world. Forget the RS- models from Audi, the M-models from BMW, and the Mercedes-Benz AMGs, none can stack up to the 707-horsepower Hellcat.
