A toy vehicle includes a central housing having first and second oppositely disposed sides. A first wheel is rotatably mounted on the first side of the housing, and a second wheel is rotatably mounted on the second side of the housing. Each of the first and second wheels has a central hub and a plurality of individual vanes rotatably attached to the hub. Each hub has a center disposed along a first axis of rotation. Each vane is rotatable about a second vane axis extending transversely with respect to the first axis. An end of each vane distal to the hub forms a circumferential surface portion of one of the first and second wheels.
