The factory-rated output of Dodge’s supercharged 6.2-liter HEMI ranges from 707 hp in the original Challenger SRT Hellcat to 1,025 hp in the Challenger SRT Demon 170. Ranked below are six distinct factory output steps—not six wholly different engines. Dodge’s ratings are manufacturer figures, not independent dyno measurements, and the Demon 170’s rating includes specified engine speeds.

Six Hellcat-family HEMI V8s ranked by horsepower

The ranking follows factory-rated horsepower for the named vehicle and configuration. Torque is included where the cited Dodge material supplies it. Because the figures come from different model years and sources, they should not be read as results from one controlled test or identical fuel conditions.

  1. 707 hp: 2015–16 Challenger SRT Hellcat

    Dodge’s 2016 brochure rates the original Challenger SRT Hellcat’s supercharged 6.2-liter HEMI V8 at 707 hp and 650 lb-ft of torque. This is the early Hellcat baseline, rather than the only output ever assigned to a standard Hellcat. Dodge’s 2016 Challenger brochure.

  2. 717 hp: later standard Challenger SRT Hellcat

    DodgeGarage’s fact sheet for the 2022 model year lists the standard Challenger SRT Hellcat at 717 hp. That later rating is 10 hp above the early 707-hp figure; attaching the model year and configuration avoids treating the two ratings as interchangeable. DodgeGarage’s 2022 Challenger fact sheet.

    The same DodgeGarage fact sheet rates the Challenger SRT Hellcat Redeye’s high-output 6.2-liter HEMI at 797 hp. The Redeye is a higher-output configuration in the same supercharged HEMI family, not a wholly unrelated engine architecture. DodgeGarage’s 2022 Challenger fact sheet.

  4. 807 hp: Challenger SRT Super Stock

    DodgeGarage lists the Challenger SRT Super Stock at 807 hp and describes its high-output engine as using a unique calibration. It therefore represents a distinct factory output step above the Redeye, though the two share the underlying high-output 6.2-liter HEMI family. DodgeGarage’s 2022 Challenger fact sheet.

  5. 840 hp: 2018 Challenger SRT Demon

    Dodge cited 840 hp for the 2018 Challenger SRT Demon in its 2023 Demon 170 announcement. The announcement’s reference to the earlier Demon does not give the same full engine-speed context as it does for the Demon 170, so this figure is best treated as Dodge’s stated rating rather than a directly comparable test result. Dodge’s Demon 170 announcement, distributed by PR Newswire.

  6. 1,025 hp: Challenger SRT Demon 170

Why does a Hellcat have more than one horsepower rating?

“Hellcat” identifies a family of Dodge vehicles and related supercharged 6.2-liter HEMI configurations, not one fixed horsepower number. The original Challenger SRT Hellcat carried a 707-hp rating in Dodge’s 2016 brochure; DodgeGarage’s 2022-model-year fact sheet lists the standard Challenger at 717 hp, with higher-output Redeye and Super Stock calibrations. The vehicle and model year are essential parts of the answer to “How much horsepower does a Hellcat have?”

How do other Hellcat applications fit the ranking?

The six entries above rank distinct output steps, not every Hellcat-powered vehicle. Dodge’s cited materials also list the Durango SRT Hellcat at 710 hp and the Charger SRT Hellcat at 717 hp; the Charger Redeye is listed at 797 hp. These applications show why a list of vehicles would produce a different ranking from a list of distinct ratings. The Durango’s 710-hp output sits between the early Challenger’s 707 hp and the later standard Challenger’s 717 hp, but it does not add a new step to this six-rung ranking.

What the ratings do—and do not—tell you

These numbers are Dodge’s factory ratings. They establish how the manufacturer described each configuration, but they are not independent measurements of output in a particular vehicle. The cited Demon announcement does not establish matching fuel or test conditions for the 2018 Demon and Demon 170, so the ranking is a comparison of stated factory horsepower rather than a controlled performance test.
