What Dodge motor has the most horsepower?
The Dodge engine with the most horsepower is the supercharged 6.2-liter Hemi V8 used in the Challenger SRT Demon, officially rated up to 840 horsepower on 100-octane fuel (808 horsepower on 93-octane).
How horsepower is measured and what counts for Dodge
In modern Dodge muscle cars, horsepower is measured as SAE net horsepower, which reflects engine power after the engine’s accessories are accounted for. Dodge’s top figures often depend on fuel grade and testing conditions, with race fuel unlocking higher numbers in limited runs. The Demon’s prestige rests not only in raw horsepower but in its factory‑turnished, street‑legal design for drag racing, while other Hellcat variants offer very high power in more broadly available configurations.
The horsepower leaders in Dodge’s current and historical lineup
Below is a look at the Dodge engines and configurations that have pushed the horsepower envelope, including a limited‑run halo car and the top modern production option. The list focuses on factory specifications rather than aftermarket tuning.
- 6.2-liter Hemi V8 supercharged (Demon) — Challenger SRT Demon: up to 808 horsepower on 93‑octane fuel, with up to 840 horsepower when running 100‑octane race fuel.
- 6.2-liter Hemi V8 supercharged (Hellcat Redeye) — Challenger/Charger Hellcat Redeye: 797 horsepower in standard configuration.
- 6.2-liter Hemi V8 supercharged (SRT Super Stock) — Challenger SRT Super Stock (introduced for the 2023 model year): 807 horsepower, making it the most powerful Dodge production car outside the Demon lineup.
These figures illustrate how Dodge has stacked high horsepower into a relatively narrow family of high‑performance V8s, with the Demon remaining the benchmark for a factory, street‑legal production car when race fuel is used. The Super Stock represents the peak for non‑Demon production cars in recent years, while the Demon’s numbers are tied to its limited‑run, drag‑focused engineering.
Current status and context
As Dodge transitioned into updates for its modern performance lineup, the Demon remains a special‑edition model that was produced for a limited time and is no longer in regular production. The 807‑horsepower Super Stock is the closest Dodge currently marketed as the top‑ranking non‑Demon vehicle, while the company continues to push performance through aerodynamics, handling, and track-ready variants rather than simply chasing higher horsepower figures.
Summary
In Dodge’s catalog, the champion for horsepower is the 6.2-liter Hemi V8 supercharged Demon, reaching up to 840 hp on octane-boosted fuel (808 hp on 93 octane). Among ongoing production cars, the Challenger SRT Super Stock holds the crown with 807 hp, representing the peak for non‑Demon Dodge models. Dodge’s approach blends extreme power with exclusive engineering, producing a lineage where horsepower serves as a headline alongside track-ready capabilities.
