Overview

The Grotti Speeder VI is a boats & watercraft-class watercraft from Grotti, engineered for high-speed aquatic pursuit and coastal exploration. Drawing clear inspiration from the Riva 66 Ribelle, it brings passionate Italian design flair to the streets of Vice City.

In Grand Theft Auto VI, vehicle handling and weight have been dramatically overhauled compared to GTA V. The Grotti Speeder VI 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.
