A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.
