The Dodge Charger Hellcat certainly isn't lacking in power but that hasn't stopped Hennessey Performance from creating a new HPE850 package for the "fastest and most powerful sedan in the world."
Starting under the hood, the supercharged 6.2-liter V8 engine has been equipped with a port matched throttle body, an upgraded lower pulley and a high-flow air filter. The company also installs a new ECU and a ported supercharger housing. Thanks to these modifications, the engine develops 852 bhp (635 kW).
Besides the performance tweaks, the model has embroidered headrests, an individually-numbered plaque and Hennessey exterior badging.
