An energy absorbing assembly for impact energy absorption can comprise: an elongated plastic member having a major axis, a first side and a second side, comprising a central portion disposed between a first end portion and a second end portion, the second side defines a channel extending from the first end portion to the second end portion; and an elongated insert having a front, edges, tips, and a rear, wherein the insert is configured to flex upon impact, and is removably friction fit within the channel such that the plastic member surrounds the front, and greater than or equal to 50% of the edges and tips. The energy absorbing assembly can be configured to attach to a vehicle to absorb energy absorption impact. A vehicle can comprise: a vehicle rail and the energy absorbing assembly attached to the vehicle rail.
