The series LR's had complete Birmabright (aluminum/magnesium alloy) bodies; though the more recent models Discovery I/II, LR3, Range Rover have used only aluminum body skins.* Meaning the structural body is steel, though the outward panels are aluminum. The 2013 Range Rover has a complete aluminum body (skin and structure), with a 700lb weight reduction for US models.[1] 1. http://www.caranddriver.com/news/2013-land-rover-range-rover-photos-and-info-news http://www.caranddriver.com/news/2013-land-rover-range-rover... * Various differences among models some have steel roofs, doors etc.
