A control arm includes a wheel side end, a body side end, a first connecting member extending between the wheel side end and the body side end, a second connecting member extending between the wheel side end and the body side end, and having a reduced section portion, and a fracture zone extending through the first and second connecting members in a substantially fore-aft direction of the vehicle, the reduced section portion being within the fracture zone. A thickness of the reduced section portion is tunable to establish a controlled fracturing during a small overlap rigid barrier impact event where: (i) an initial fracture of the first connecting member occurs within the fracture zone, and (ii) a secondary fracture of the second connecting member occurs within the fracture zone at the reduced section portion, to thereby provide a desired rearward trajectory of the wheel assembly during the impact event.

A motor vehicle has a passenger compartment and two side members provided with respective rear portions, arranged longitudinally at the passenger compartment, and respective struts, which project forward of the passenger compartment;

the motor vehicle has a crossbar with front attachment portions and rear attachment portions fixed to the side members by means of connecting devices, so as to keep the crossbar suspended in relation to the struts; the connecting devices have at least one weakened zone, designed so as to cause at least part of the crossbar to detach from the side members when a given load threshold is exceeded; the connecting devices have a first pierced wall, which is part of the front or rear attachment portions, a second pierced wall, which is part of the side members, and a bolt that tightens the first and second wall together; the weakened zone is defined by at least one slot cut in the first wall, beginning from a hole edge of the first wall itself.

An embodiment vehicle rear body structure includes a partition panel coupled to a boundary point of a vehicle body intermediate portion and a vehicle body rear portion, a first mount assembly connected to the partition panel and configured to support a hydrogen tank, and a second mount assembly connected to a rear cross member provided in the vehicle body rear portion and configured to support the hydrogen tank at a position lower than the first mount assembly.
