A vehicle midgate includes a generally U-shaped reinforcement member that cooperates with an inner panel and an outer panel to define a cavity for containing a selectively retractable window. The U-shaped reinforcement member has a closed cross section so as to form a channel separate from the cavity. The reinforcement member provides increased stiffness and improved water management inside the midgate.
A vehicle closure system includes a first track portion rigidly connected with respect to a vehicle body and a second track portion rigidly connected with respect to a closure panel. The closure panel is selectively movable between open and closed positions. The first and second track portions align when the closure panel is in the closed position. The track portions facilitate movement of a window between a closed position and a stowed position, while allowing independent movement of the closure panel with respect to the window.
