Dodge Challenger Horsepower Specs By Year
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| E85 maximum output | 1,025 hp | At 6,500 rpm |
| E85 peak torque | 945 lb-ft | At 4,200 rpm |
| E10 maximum output | 900 hp | Premium gasoline calibration |
| E10 peak torque | 810 lb-ft | Fuel-dependent factory rating |
Dodge states that output changes automatically with detected ethanol content. Maximum output becomes available above the specified high-ethanol threshold; the cluster indicates the detected state. That makes the fuel qualifier part of the specification, not a footnote that can be removed from the headline. The 1,025-hp figure occurs at 6,500 rpm and peak E85 torque at 4,200 rpm.

2023 Dodge Challenger Demon 170 Horsepower: E10 vs. E85 FAQs
How much horsepower does the 2023 Challenger SRT Demon 170 make?+
1,025 hp at 6,500 rpm on an E85 ethanol blend, with 945 lb-ft of torque at 4,200 rpm. On E10 premium gasoline the same car is rated at 900 hp and 810 lb-ft.
Why are two different horsepower figures published for the same car?+
Output changes automatically with the ethanol content the car detects, so the fuel is part of the specification rather than a footnote. Maximum output becomes available above the specified high-ethanol threshold, and the instrument cluster indicates the detected state.
Does the Demon 170 rating apply to a Hellcat, Redeye or 2018 Demon?+
No. These figures describe only the factory Demon 170 and its ethanol-sensing calibration. The 2018 Demon, Hellcat, Redeye, Super Stock and ordinary Challenger models carry their own ratings even though several share related supercharged 6.2L HEMI architecture.
Will running pump gas in a Demon 170 reduce its output?+
Yes — on E10 premium the factory rating is 900 hp and 810 lb-ft rather than 1,025 hp and 945 lb-ft. The reduction is a designed calibration response to detected ethanol content, not a fault.
