Abstract
A vehicle differential case is disclosed, the case having an interior and an exterior configuration which provides an increased internal volume for, among other things, lubricant for components of the differential mechanism, while at the same time providing excellent structural strength. Importantly, the weight versus stiffness ratio of the differential case so described is significantly improved compared to known differential cases.
