ABSTRACT:
A vehicle door includes an inner panel having strengthening corrugations to function as an impact beam, thereby negating the need for a separate impact beam. The inner panel is preferably characterized by a generally concave shape to increase vehicle interior space compared to prior art doors. A forming technique employing fluid pressure is preferably employed to form the inner panel.
