A vehicle frame assembly comprising: - a frame having two rails extending in a longitudinal direction; - an electric subassembly comprising a sub-frame arranged between the rails and secured to each rail by at least one side mount; - an energy absorbing device (50, 150) arranged rearward of the electric subassembly and secured to the frame, the energy absorbing device (50, 150) comprising at least one elongate member (51, 151) formed as a single piece of rigid material, the elongate member (51, 151) having, in the normal state: -- a mounting portion (52, 152) secured to the frame, the mounting portion (52, 152) having at least one transverse segment (54, 154); -- at least one leg (60, 160) which extends globally downwards and which at least partially faces the electric subassembly along the longitudinal direction, the leg (60, 160) having an upper end (61, 161) connected to one end of the transverse segment (54, 154) and a free lower end (62, 162), the leg (60, 160) including an inclined segment (63, 163) which extends downwards and forward from the leg upper end (61, 161) to the leg lower end (62, 162), wherein the elongate member (51, 151) is configured to be deformed according to at least a downward and rearward pivoting movement of the inclined segment (63, 163) relative to the mounting portion (52, 152), further to a rearward movement of the electric subassembly resulting from a vehicular frontal collision, thereby absorbing energy from said collision. - a frame having two rails extending in a longitudinal direction; - an electric subassembly comprising a sub-frame arranged between the rails and secured to each rail by at least one side mount; - an energy absorbing device (50, 150) arranged rearward of the electric subassembly and secured to the frame, the energy absorbing device (50, 150) comprising at least one elongate member (51, 151) formed as a single piece of rigid material, the elongate member (51, 151) having, in the normal state: -- a mounting portion (52, 152) secured to the frame, the mounting portion (52, 152) having at least one transverse segment (54, 154); -- at least one leg (60, 160) which extends globally downwards and which at least partially faces the electric subassembly along the longitudinal direction, the leg (60, 160) having an upper end (61, 161) connected to one end of the transverse segment (54, 154) and a free lower end (62, 162), the leg (60, 160) including an inclined segment (63, 163) which extends downwards and forward from the leg upper end (61, 161) to the leg lower end (62, 162), wherein the elongate member (51, 151) is configured to be deformed according to at least a downward and rearward pivoting movement of the inclined segment (63, 163) relative to the mounting portion (52, 152), further to a rearward movement of the electric subassembly resulting from a vehicular frontal collision, thereby absorbing energy from said collision. -- a mounting portion (52, 152) secured to the frame, the mounting portion (52, 152) having at least one transverse segment (54, 154); -- at least one leg (60, 160) which extends globally downwards and which at least partially faces the electric subassembly along the longitudinal direction, the leg (60, 160) having an upper end (61, 161) connected to one end of the transverse segment (54, 154) and a free lower end (62, 162), the leg (60, 160) including an inclined segment (63, 163) which extends downwards and forward from the leg upper end (61, 161) to the leg lower end (62, 162),
