* Year: Mustang models have changed considerably over the years, with different engines and aerodynamic designs affecting top speed.
* Model: The GT500 will have a much higher top speed than the EcoBoost.
* Engine: Even within a model year, different engine options will have different power outputs and thus different top speeds.
* Modifications: Aftermarket modifications (tuning, exhaust, etc.) can significantly impact top speed.
Manufacturers rarely publish official top speeds. Instead, they focus on 0-60 mph acceleration times. To find a top speed for a *specific* Mustang, you'd need to specify the year, model, and engine, and then search for independent tests (often found on automotive review websites).
