A motor vehicle side door

摘要

A motor vehicle having a side door is disclosed having lower and upper parts. The upper part comprises a window surround for fixed and drop-down windows. The fixed window has a much larger barrel radius of curvature than the drop-down window and the inclusion of the fixed window reduces the chord length of the drop-down window between a beltline of the motor vehicle and a lower edge of the fixed window. This combination allows the use of more tumblehome on the motor vehicle without needing to increase the thickness of the lower part of the side door in order to accommodate the drop-down window when it is lowered.
