A dual hinged door assembly for a vehicle is provided, the assembly including an upper door portion and a lower door portion. The upper door portion, which may include a window, pivots about a primary axis formed by its juncture with a structural member in the roof. The lower door portion, which may include a window, pivots about a secondary axis formed by its juncture with the upper door portion. Primary and secondary drive systems may be used to provide independent powered motion of the upper and lower door portions. Each drive system may include a powered strut, e.g., a hydraulic strut, and a non-powered strut, e.g., a gas strut.
