How much horsepower does the Dodge Demon 170 have?

The Dodge Challenger SRT Demon 170 is officially rated at 1,025 horsepower when fueled with 100-octane race gas, making it the most powerful production Dodge in recent memory.

Beyond the headline figure, this article details what that horsepower means, how Dodge defines the rating, and other notable facts about the Demon 170’s design, production, and performance.

Official horsepower and fuel requirements

Power output for the Demon 170 is fuel-dependent, with Dodge publishing a precise horsepower figure tied to a high-octane fuel blend. The following points summarize the official stance and related details.

• Official horsepower: 1,025 hp when using 100-octane fuel (race gas).


• Limited production: the Demon 170 was produced in a limited run of 3,000 units worldwide.


• Drivetrain: rear-wheel drive with an eight-speed automatic transmission.

Understanding how octane affects output helps explain why the figure is stated specifically for 100-octane fuel. In Dodge’s release materials, the 1,025-horsepower rating is linked to race-grade fuel, while other octane levels yield lower outputs. The company does not publish a single official horsepower figure for every alternate fuel grade.

Fuel strategy and performance context

Octane rating matters because it determines how much timing and boost the engine can safely tolerate before detonation, which in turn influences horsepower. The Demon 170’s 1,025 hp figure reflects optimized calibration for high-octane race gas, a key selling point for drag-strip use and performance testing.

In practice, enthusiasts seeking maximum performance for straight-line acceleration should note that 100-octane fuel is required to reach the published 1,025 hp, and availability of such fuel varies by region. Dodge frames this power output as part of a broader package designed for extreme, track-oriented driving experiences.

Production details and hardware highlights

Beyond the headline horsepower, several production and hardware elements define the Demon 170’s performance profile. The list below covers the core facts Dodge has emphasized in public materials.

• Engine: 6.2-liter supercharged Hemi V8 powering the Demon 170 to its peak output on race fuel.


• Transmission: eight-speed automatic paired with chassis tuning aimed at drag-oriented use.


• Production run: limited to 3,000 units globally, reinforcing its status as a specialty model.

These elements—exclusive production, a high-output powertrain, and race-oriented calibration—underscore the Demon 170’s role as a halo performance car for Dodge, rather than a mass-market performance option.

What this means for enthusiasts

For collectors and performance enthusiasts, the 1,025-horsepower Demon 170 represents a culmination of Dodge’s drag-focused engineering, packaged in a street-legal car. The requirement for high-octane fuel, limited production, and the vehicle’s track-ready features position it as a benchmark for capability rather than everyday usability. Prospective buyers should plan for fuel availability, maintenance considerations for a high-performance powertrain, and the exclusive nature of the model.

Summary

The Dodge Challenger SRT Demon 170 stands as a landmark in Dodge’s performance narrative, delivering 1,025 horsepower on 100-octane fuel and existing in a strictly limited run of 3,000 units. Its power comes from a tuned 6.2-liter supercharged Hemi V8 and is supported by an eight-speed automatic transmission in a rear-wheel-drive layout. While the headline figure highlights its extreme capabilities, the actual output will vary with fuel quality, making the Demon 170 a rare blend of showroom legitimacy and drag-strip raw power.

• Top Speed: The official top speed is not a high number, capped at approximately 151151151 mph because of its specific purpose as a drag car. Its quarter-mile trap speed is also 151.17151.17151.17 mph. 
• Acceleration (0−600 minus 600−60 mph): The Demon 170 achieves a 0−600 minus 600−60 mph time of 1.661.661.66 seconds, making it one of the fastest-accelerating production cars ever made. 
• Quarter-Mile: It can complete a quarter-mile in 8.918.918.91 seconds, with a trap speed of 151.17151.17151.17 mph.

What is faster, a Demon 170 or a Hellcat?

The Challenger Hellcat posted an 11.7-second quarter mile3 in MotorTrend testing, and while that is an impressive feat that would've blown minds back in the heyday of American muscle, the Challenger Demon 170 would've been mistaken for witchcraft with its 8.91-second quarter-mile time.

Is the Demon 170 street legal?

Yes, the Dodge Challenger SRT Demon 170 is street-legal and meets all safety and emissions regulations for public roads, despite being built for drag racing. However, its extreme performance capabilities and specialized drag radial tires mean it requires careful handling on the street, especially in wet conditions. Due to its sub-9-second quarter-mile times, the National Hot Rod Association (NHRA) has banned stock Demon 170s from its sanctioned competitions, as those events have a rule against cars running faster than 10 seconds on their own.

• Street-legal compliance: The car is engineered to meet all necessary safety and emission standards, but it does not come with a roll cage as standard equipment. 
• Performance and handling: It can go from 000 to 606060 mph in as little as 1.661.661.66 seconds on an ideal surface. The specialized drag radial tires, while providing necessary grip for drag racing, are not designed for the same level of durability as a standard road tire and can be particularly risky in wet conditions. 
• Drag racing ban: Its incredibly fast performance means the stock Demon 170 cannot compete in NHRA-sanctioned drag races, as it runs the quarter-mile in under 9 seconds, which is too fast for the current regulations.
