Which Dodge Challenger has the most horsepower?
The Dodge Challenger SRT Demon 170 is the most powerful Challenger ever built, delivering about 1,025 horsepower on E85 fuel (and well over 1,000 hp on other high-octane blends). This crown surpasses all earlier Challenger variants.
Current king: the Demon 170
The SRT Demon 170, announced for the modern Challenger lineup, represents the peak of horsepower in the model’s history. It uses a heavily upgraded 6.2-liter Hemi V8 with advanced forced induction and fueling to exceed the 1,000-horsepower threshold. This is a limited-edition variant designed with straight-line performance in mind rather than everyday driving comfort.
- Power output: up to 1,025 horsepower on E85 fuel; commonly over 1,000 horsepower on high-octane pumps
- Engine: 6.2-liter Hemi V8 with supercharger and enhanced internals
- Fuel capability: flexible-fuel system optimized for maximum power on E85
- Transmission: TorqueFlite eight-speed automatic
- Production: limited-edition model, part of Dodge’s final-era Challenger lineup
These features collectively make the Demon 170 the apex of Challenger performance from the factory, reflecting Dodge’s intent to end the modern Challenger on a high note for horsepower enthusiasts.
Historical horsepower milestones in the Challenger lineup
To place the Demon 170’s achievement in context, here are notable horsepower benchmarks from previous Challenger variants. This helps illustrate how the model’s power has evolved over time.
- 2018 Dodge Challenger SRT Demon: factory-rated up to 840 horsepower on 100-octane fuel
- Dodge Challenger SRT Hellcat (non-Widebody, early models): around 707 horsepower
- 2019–2022 Dodge Challenger SRT Hellcat Redeye Widebody: up to 797 horsepower
Together, these milestones show the dramatic leap to the 1,025-horsepower Demon 170, which stands as the current horsepower crown for the Challenger family.
Why horsepower matters for the Challenger audience
For enthusiasts, raw horsepower is only part of the story. Power must be translated through traction, gearing, weight, and chassis tuning. The Demon 170 pairs its high output with drag-focused launch systems, specialized suspension calibration, and a drivetrain designed to handle extreme straight-line acceleration—the core reason it holds the horsepower crown within the Challenger lineup.
In sum, the Dodge Challenger SRT Demon 170 is the most powerful Challenger to date, delivering about 1,025 horsepower on E85 and surpassing all prior variants. No other production Challenger currently surpasses this figure, cementing the Demon 170’s place in the model’s history.
Summary: As of now, the strongest Dodge Challenger is the SRT Demon 170, with approximately 1,025 horsepower on flexible fuel. This capstone model eclipses earlier power figures from Demons and Hellcats, marking the peak of horsepower within the Challenger lineage.
