* The specific model year of both the police Challenger and the "regular" car: Performance varies significantly between model years and trims even within the same car line. A 2023 Challenger Pursuit might be considerably faster than a 2010 sedan, for instance.
* The "regular" car: A base-model economy car will be significantly slower than a high-performance sports car. Comparing a police Challenger to a Honda Civic is a much different comparison than to a Mustang GT.
* Modifications: Police vehicles often have modifications that impact performance (though usually not for top speed; they focus on braking and handling). Regular cars may also be modified.
* Driving conditions: Speed is affected by road conditions, weather, and driver skill.
While Dodge Challenger Pursuit models are designed for high performance, exceeding a regular car's speed depends entirely on the comparison. Some "regular" cars could come close to the Challenger's speed. Others will be considerably slower.
