A vehicle body structure includes a forecabin crossbeam and two front longitudinal beams disposed at intervals along a left-right direction. The forecabin crossbeam and the two front longitudinal beams are integrally formed and are at least partially located at the bottom of the front longitudinal beam.

A vehicle support structure according to an exemplary aspect of the present disclosure includes, among other things, a cross-member of a vehicle support structure. The cross-member extends longitudinally along a cross-member axis. The frame assembly further includes a rail of the vehicle support structure. The rail extends longitudinally along a rail axis that is transverse to the cross-member axis. The rail extends into a pocket of the cross-member such that a portion of the rail is nested within the cross-member.
