A door assembly is provided that includes integral impact regions that ob viate the need for a separate impact beam. The door assembly includes an out er panel and an inner panel, operably connected to the outer panel so that a compartment is formed therebetween. At least one hardware-mounting surface is integrally formed from the inner panel and extends towards the outer pane l. Each of the hardware mounting surfaces is operable to mount a hardware co mponent between the inner and outer panels. At least one integrally-formed i mpact region is provided on the inner panel that is operable to strengthen t he door assembly and increase its intrusion resistance of the vehicle door d uring a collision. The inner panel has substantially no large access opening s that would be deleterious to impact resistance and substantially seals the vehicle passenger compartment from the external environment. The at least o ne impact region is also displaced at least as far away from the outer panel as the at least one hardware mounting surface.
