Hennessey Performance is in the business of taking extremely powerful cars and turning them into full out street monsters. Case in point, the Hennessey Charger Hellcat HPE850. The insane performance upgrade takes a stock Dodge Charger SRT Hellcat and increases the power output to an unbelievable 852 hp. The Charger SRT Hellcat is already the world's most powerful sedan, so what would that make a Charger with the HPE850 upgrade? We're afraid to even ask.

With the Charger HPE850 kit comes extraordinary power and an unmatched sound. Seriously, this kit gives the world's most powerful sedan one of the world's greatest soundtracks.
