* Condition of the vehicle: Worn parts, tire pressure, and overall maintenance significantly impact performance.
* Aerodynamics: Any modifications affecting drag (like aftermarket spoilers or even just accumulated grime) will change the top speed.
* Gear ratios: The final drive ratio in the differential affects how speed translates to engine RPM.
* Altitude and weather conditions: Air density plays a role; thinner air at higher altitudes means less power. Headwinds will also decrease top speed.
* Driver skill (and bravery!): Pushing a car to its absolute limit is risky and shouldn't be attempted unless on a closed track.
While factory specifications might suggest a top speed in the range of 120-130 mph, achieving that in real-world conditions is unlikely and unsafe. It's more realistic to expect a maximum speed closer to the 110-120 mph range in ideal conditions for a well-maintained vehicle. Anything beyond that would be pushing the car's limits and potentially compromising safety.
