In Grand Theft Auto VI, vehicle handling and weight have been dramatically overhauled compared to GTA V. The Principe Diabolus Custom benefits from heavier physics simulation, realistic roll dynamics, and authentic torque curves designed to reward skilled drivers on both Leonida's open freeways and narrow downtown alleys.
