Hennessey unleashes 850-hp Dodge Charger Hellcat

If 707 horsepower isn’t enough, Texas-based tuner Hennessey Performance has released an even wilder version of the Dodge Charger SRT that benefits from a generous bump in power.

Dubbed HPE800, Hennessey’s Hellcat packs an evolution of the stock model’s supercharged 6.2-liter V8 engine that has been tuned to deliver 805 horsepower at 6,200 rpm in its most basic state of tune. The additional grunt comes from a new ECU, a beefier lower pulley that increases boost, a high-flow air filter and a port-matched throttle body.

If 805 ponies is still too low, Hennessey can raise the eight-cylinder’s output to 852 horsepower at 6,200 rpm by adding more boost and a ported supercharger housing. Performance specifications haven’t been published yet, but it’s safe to bet the 852-horsepower HPE850 is considerably faster than a stock Hellcat, which is capable of reaching 60 mph from a stop in about three seconds.

Both versions are otherwise stock except for minor details like model-specific emblems all around and embroidered headrests. Numbered plaques on the dash and in the engine bay wrap up the custom design.

Hennessey has not disclosed how many examples of the HPE800 and HPE850 it plans on building and how much of a premium each one will carry over the stock Dodge Challenger SRT Hellcat.
