Hennessey is well known for taking high performance cars and raising the bar another notch with them. For their latest creation, they used a Sublime Green Dodge Challenger SRT Hellcat. As most know, the stock power numbers produced by the Hellcats come in at 707 horsepower. While plenty for most, Hennessey wanted to see what they could achieve with some modifications.

After some tweaking and putting their famed Hennessey touch on it, they came out with something quite fantastic; The Hennessey HPE850 Upgrade package. Available to order for your 2015-2016 Hellcat Challenger; with this upgrade package, it bumps the power on the Hellcat to a staggering 852 bhp @ 6,200 rpm! They say this is an estimated power rating at the engine. Actual power will be measured at the rear wheels, before and after the upgrades are installed and tuned. Rear wheel horsepower and torque figures are approximately 15-20% lower than the factory published power figures which are measured at the crankshaft on an engine dyno.

The HPE850 package includes the following:
• New ECU
• Upgraded tuning software
• High flow air filter element
• Lower pulley upgrade (increases boost by 1-2 psi)
• Port matched throttle body
• Hennessey embroidered head rests
• Exterior Hennessey emblem
• Exterior HPE850 emblems
• Serial numbered dash plaque
• Serial numbered plaque in engine compartment
