The vehicle frame assembly (100), comprises a frame (3) having two rails (6) extending in a longitudinal direction (X), and at least one cross-member (7) coupling the rails and extending along a transverse direction (Y), an electric subassembly (10) comprising a sub-frame (11) which is arranged between the rails (6), forward of the cross-member (7), the sub-frame (11) being secured to each rail (6) by at least one side mount (13), and an energy-absorbing system (50) which is arranged between the sub-frame (11) and the cross-member (7), and attached to at least one of the sub-frame and the cross-member, the energy-absorbing system (50) extending in the longitudinal direction and being less stiff than the sub-frame (11) and the cross-member (7) to deform and absorb p energy from a vehicular collision. L'ensemble châssis de véhicule (100) comprend un châssis (3) comprenant deux rails (6) s'étendant dans un sens longitudinal (X), et au moins une traverse (7) accouplant les rails et s'étendant dans un sens transversal (Y), un sous-ensemble électrique (10) comprenant un sous-châssis (11) qui est agencé entre les rails (6), à l'avant de la traverse (7), le sous-châssis (11) étant fixé à chaque rail (6) par au moins un support latéral (13), et un système d'absorption d'énergie (50) qui est agencé entre le sous-châssis (11) et la traverse (7), et fixé à au moins un élément parmi le sous-châssis et la traverse, le système d'absorption d'énergie (50) s'étendant dans le sens longitudinal et étant moins rigide que le sous-châssis (11) et la traverse (7) pour se déformer et absorber une partie de l'énergie d'une collision de véhicules.
