The Hellcat's significantly more powerful engine usually gives it a clear advantage in straight-line speed. The Mustang GT, while still very fast, typically has slightly less horsepower and torque.
Therefore, while a *specific* Mustang GT might outperform a *specific* Charger SRT in certain circumstances (e.g., a particularly skilled driver, different track conditions favoring the Mustang's handling), in a direct comparison of comparable models, the Charger SRT Hellcat is almost always faster in acceleration.
