Kobe Steel, Ltd.'s aluminium side-impact door beam is being used in Mitsubishi Motor Corporation's Lancer Evolution VIII MR, a four-door sports sedan that went on sale earlier this year in Japan. This is the first time the aluminium extrusion has been adopted by Mitsubishi. In comparison to door beams made of high strength steel sheet rolled into the form of a pipe, aluminium side-impact beams reduce the weight of a four-door car by roughly 3.5 kg.
