Abstract

A vehicle frame includes first and second lower rails and first and second upper rails operatively interconnected. Cross members horizontally interconnect the lower rails and the upper rails, and stanchions vertically interconnect the upper rails and the lower rails. The frame provides improved stiffness and strength at a reduced mass compared to the prior art.
