No one gets into a 707 horsepower Dodge Challenger Hellcat and says “you know what, I wish this thing had more power.” But since the whole concept of tuning is addressing issues nobody’s complaining about, here’s a Hennessey Challenger Hellcat with 850 horsepower.

And this is not even the end of it, as there is a 1000 hp package coming. The Hennessey Challenger Hellcat we have here boasts the Texan tuner’s HPE850 package, and if you thought an extra 150 hp won’t make that big a difference in the performance of the car, well, check out how this monster moves about in this demonstration video. It’s a Navy destroyer with a nuclear-powered engine!

Hennessey Challenger Hellcat HPE850 tuning package includes a new ECU with upgraded software, high flow air filter element, lower pulley upgrade which increases the supercharger boost by up to 2 psi, and port matched throttle body. There are visual upgrades as well, such as Hennessey embroidered head rests, exterior badging, serial numbered dash and engine compartment plaques. That’s what you get by default. Hennessey is also capable of customizing the vehicle to your liking inside and out and offers custom wheels and suspension treatment as well.
