MOTOR VEHICLE PROVIDED WITH A RELEASE SYSTEM TO UNCOUPLE A CROSS MEMBER IN THE ENGINE COMPARTMENT IN THE EVENT OF A FRONT CRASH

A motor vehicle has two upper struts, which project forward from a passenger compartment and are arranged above two lower struts, which extend along respective substantially rectilinear axes inclined from the bottom upwards, going forward; the lower struts have respective intermediate portions with such a variation in cross section to define a preferential bending zone; the rear ends of the lower struts are fixed to a cross member connected to the upper struts by means of two connection members, which are substantially vertical and have respective breakable zones designed so as to break when a given load threshold is exceeded; the motor vehicle also has a powertrain connected to the cross member and to the upper struts by means of supports which are distinct from the connection members and are breakable in the event of a front crash.
