The present invention is a vehicle stability system that affords safe turn with higher speed as well as maximum brake performance and resists rollover by using one or more electrical and mechanical modes to shift the center of gravity of the vehicle into a more stable position in the event of a turn condition. A preferred embodiment of the present invention utilizes an active tilt control to tilt the vehicle in the opposite direction to the vehicle's natural inclination to tilt. A second preferred embodiment utilizes a shifting weight, that is a ballast or any heavy part of the vehicle to move the center of gravity toward to side of the vehicle tending to lift up during a tilt condition. The first and second preferred embodiments can be used alone or in combination to create a more dynamic stable condition for the vehicle in turn mode.
