The higher mass of the electric vehicles and the increasing presence of these vehicles in the fleet suggest an urgent need to limit the stiffness aggressiveness of these vehicles. Published research indicates that much of the benefits of force-limited and pretensioned belts has been offset by the increased stiffness of vehicle front structures. This increase in stiffness increases the vehicle acceleration for each added increment of vehicle deformation during collisions, thereby increasing the crash severity. Control of vehicle stiffness during the initial 400 mm. of the vehicle front structure should be a priority for crash safety regulations.
