What is the top speed of the demon 170?

The Demon 170 is officially rated to reach 203 mph in controlled, closed-course testing, reflecting its lineage as a drag-focused, high-performance variant. This article breaks down what that top speed means, how it was achieved, and the factors that can influence whether a customer reproduces it in real-world conditions.


What is the Demon 170?


The Demon 170 is a limited-edition version of the Dodge Challenger SRT Demon, produced to celebrate a milestone and push the Challenger lineup to extreme straight-line performance. Built on the Challenger platform, it features a supercharged V8, drag-oriented tires, and specialized tuning designed to maximize top-end speed on a controlled track.


Official top speed claim


Dodge officially lists the Demon 170 with a top speed of 203 mph under specific test conditions. This figure is tied to a closed-course evaluation using fuel and tires selected for peak performance in straight-line runs.


Key features and specifications that contribute to the top speed are summarized here:



  • Drag-focused engineering: enhanced aerodynamics and chassis tuning designed to minimize drag while sustaining high-speed stability.

  • Powertrain setup: a supercharged V8 tuned for high-output when running suitable fuel blends.

  • Specialized propulsion and cooling: components calibrated to maintain performance during sustained high-speed runs.

  • Limited production and testing context: the 203 mph figure references controlled conditions on a test track rather than typical street use.


In short, the 203 mph figure reflects Dodge's official testing parameters and the car's design intent; real-world results can vary based on fuel, tires, and conditions.


Testing and verification


How the top speed figure is validated for cars like the Demon 170 involves careful testing and independent verification to ensure consistency and safety.


Notes on measurement



  1. The manufacturer conducts closed-track tests with controlled weather, fuel, and tire choice to establish a baseline top speed.

  2. Automotive media and third-party testers may replicate similar tests under their own conditions to verify consistency.

  3. Differences in fuel, tire wear, altitude, temperature, and driver technique can lead to variations in measured top speed outside the official test.


Taken together, the 203 mph figure is an official benchmark under specific, controlled conditions, with other tests often producing close but not identical results depending on setup.


What influences the top speed


Numerous factors determine whether a Demon 170 reaches its claimed top speed in practice. While the car is engineered for extreme straight-line performance, actual speeds hinge on more than just engine output.



  • Fuel type and quality: ethanol-enhanced tuning can unlock higher output in the Demon 170, affecting peak speed.

  • Tire choice and condition: drag-radial tires used for top-speed tests provide different grip and contact characteristics than street tires.

  • Aero and body configuration: active and passive aerodynamics influence drag and stability at high velocity.

  • Vehicle weight and balance: fuel load and any additional equipment can alter acceleration and top-end reach.

  • Environment: altitude, humidity, and ambient temperature change air density and cooling efficiency, impacting power delivery and top speed.


Ultimately, while the Demon 170 is engineered to achieve very high speeds, real-world results will vary with conditions and setup.


Summary


The Dodge Challenger SRT Demon 170 is officially capable of reaching 203 mph in controlled testing, underscoring its role as a pinnacle of Dodge’s drag-focused engineering. This top speed number reflects specific test parameters, fuel, tires, and conditions. In everyday use, factors such as fuel quality, tire wear, and environmental conditions will influence whether the car approaches that benchmark. The Demon 170 stands as a landmark in production performance, combining extreme power, specialized tires, and track-oriented tuning to push the boundaries of street-legal speed.

How fast does a Dodge Demon 170 go?


The Dodge Demon 170 has a quarter-mile trap speed of 151.17151.17151.17 mph and a top speed of 149149149 mph, which is limited by its factory drag radials. While some sources claim a higher top speed of around 215215215 mph, this is unconfirmed and not recommended due to the tire limitations.

  • Quarter-Mile Performance: It completes the quarter-mile in 8.918.918.91 seconds at a trap speed of 151.17151.17151.17 mph. 
  • 0-60 mph Acceleration: The Demon 170 is famous for its 0−600 minus 600−60 mph time of just 1.661.661.66 seconds, achieved under ideal conditions. 
  • Top Speed: The car's top speed is electronically limited to 149149149 mph due to the rating of the factory-equipped Mickey Thompson drag radial tires. 
  • High-Speed Handling: At speeds above 170170170 mph, the car experiences significant "chime walking" or side-to-side instability with the factory setup, making it unsafe to exceed its speed-limited top speed.
