* Condition of the vehicle: Tire wear, engine tune, and overall mechanical condition all affect performance.
* Road and weather conditions: Headwinds, altitude, and road surface greatly influence top speed.
* Driver skill and weight of the car: Aggressive driving and added weight (passengers, cargo) reduce the top speed.
While some sources claim a top speed *around* 140 mph, this should be considered an optimistic estimate under *ideal* conditions. It's likely that most 1992 Dodge Stealth R/Ts would reach a top speed closer to 130 mph in real-world scenarios. The car was electronically limited to some degree, but the exact limit varied. Therefore, there is no single definitive answer.
