Meet the 850 Horsepower Hellcat Challenger by Hennessey Performance
Hennessey Performance has recently made a more powerful version of the already powerful 2015 Dodge Challenger SRT HEMI Hellcat. To be more precise, there are three versions of the Hellcat Challenger, the HPE800, HPE850 and the most powerful HPE1000. Now, we’re going to make a small review of the Hennessey HPE850 Challenger version, which as you know, it has 850 horsepower.
The exterior and the interior of the challenger remain the same, but the most dramatic changes are made under the hood. The Hennessey Performance has added their performance HPE850 package to the well-known Supercharged Chrysler’s 6.2 liter or 370 cubic-inch SRT HEMI Hellcat small-block V8 engine. With this change the engine now produces 852 horsepower at 6,200 rpm. Bellow, there are videos of the actual HPE850 version, Dynojet engine and road testing. Enjoy.
