A free-ranging ride vehicle for an amusement park ride. The vehicle includes a vehicle base supporting a passenger compartment. The vehicle includes a drive system with a support platform supporting the vehicle base. The drive system imparts a set of motions including translation, cornering, sway, and heave to the support platform and, in turn, to the vehicle base and passenger compartment. The drive system includes first, second, and third leg assemblies each with a rigid leg pivotally coupled at an inner end to the support platform and supporting a wheel at an outer end. Drive motors are mounted on the legs above the wheels to, independently and concurrently, rotate the wheels and change the directional offset angle of each wheel.
